We rely heavily on our RV’s water system, for personal hygiene, washing dishes, and in some cases for doing laundry or drinking. So it’s worth taking a few minutes to give this vital system some attention.
Pressure Regulator
To protect your RV’s plumbing from damage due to excess pressure, use a water pressure regulator when connected to any external main water source. These are available at most RV dealers and supply stores and online. Many of them can be simply screwed onto the water supply hose going from the campground tap to the coach. Other larger regulators can be permanently mounted to the coach.

Prevent Freezing
To prevent damage to your RV water system from freezing weather, completely drain the system. You can do this by turning off the water pump and opening all the water faucets, hot and cold. Next, open the low point drain valves. Leave the faucets and valves open to allow all the water to drain. Do not forget to drain your water heater. This can be carried out by removing the plug in the water heater situated at the bottom of the tank. Keep the plug inside the water heater compartment so it’s not lost and reinstall it before reactivating the system.
Related video: Overview of RV Fresh Water System
Run the water pump briefly to purge it of water, to prevent freeze damage to it and the inline filter. Pour some RV antifreeze down the toilet and all the other drains (basin, sink, and shower) to ensure that the “U” traps are protected from freezing. Unscrew the shower hose from its fitting on the faucet and allow it to drain. Check ice makers. Leave the system empty and drained to prevent the build-up of micro-organisms in the water in mild weather, and to prevent pipes bursting in freezing weather.
Some owners prefer to use compressed air to blow out the lines; there are special adapter fittings which connect the campground water inlet connection to an air compressor fitting.

Another way to protect the water system from freezing is to use special RV antifreeze, which is designed for potable water systems. It’s drawn in by the RV’s water pump and circulated through the system by opening faucets and valves until the colored fluid emerges, which indicates it has reached that component.
Draining Fresh Water Tanks
To drain the fresh water tank, locate the drain valve. This is usually located outside near the water tank. Open this valve and let the water drain until empty (remove the fill cap to let air enter for a faster drain). If the tank has no drain valve or plug near the bottom, you’ll have to empty it by running water out of faucets. If you do this make sure that you do not let the water pump run dry for more than a few seconds.
Cleaning the Fresh Water System
To clean out the fresh water system follow these steps:
- Fill the water tank half full.
- Add a solution of 1/4 cup bleach and 1 gallon water for every 15 gallons tank capacity.
- Open all the faucets until the air has escaped from the system and the solution has filled the water system.
- Let the RV sit for several hours.
- Drain the water system and refill with fresh water.
- Run the fresh water through all faucets and drain the system again.
- If the water still has an unpleasant smell or taste, add a box of baking soda mixed with water into the system. This will freshen the water.
Related video: Tips for Filling Your RV Fresh Water Tank
When preparing for a season of RVing, pressurize the fresh water system with the onboard pump and with all faucets closed, allow the pump to stop when it reaches full shut-off pressure. Listen for the pump coming on after a while. If it comes on frequently with all faucets and valves off, you have a pressure leak somewhere. Check the system over for this and repair as needed.
Final Thoughts
Most trailers and motorhomes come with specific instructions on how to maintain the water system and prepare it for freezing weather. Always follow factory recommendations when they are available. This generic procedure is intended as a general guide to be used by experienced do-it-yourselfers, and if it differs from the factory information, follow those procedures.
I cannot get my system to drain…AT ALL. I have all faucets open and the low point valves ARE open as well. There is no indication that the pump is running and I do not know where it located but I dod not understand how that would impact the drainage of the system. Please please help if you can! Thank you…

Just purchased used 5th wheel. Water is cloudy white with foul odor. Filled and drained per manual; refilled with bleach water per manual; drained after 12 hours; refilled with potable water. hot water tank still has odor. Any way to get ALL the crud out of hot water tank?
Hi Richard. The best thing to do is flush the hot water tank. This is done by removing the drain plug and then turning the water supply back on while the plug is out. Water will flush out of the tank. Do this for about 10 minutes or more and then put the plug back in and fill it up. The inlet to the tank points down so by having the drain plug out and forcing water in, it stirs up the sediment on the bottom and eventually pushes most of it out of the drain. I know some people that put white vinegar in the tank to help break down sediment as well but most of the time giving the tank a good flush for 10-15 minutes seems to help a lot.

how do I drain the water heater?
Hello Michael!
What is your RV’s year, make, and model?
Thanks!
For some time I have had an occasional floor water leak on the right side of the rig starting below the wardrobe and cabinet section. After watching it for some time I know that it happens after taking a shower, and at no other time. I assume it is not the hot water heater itself, but a line coming off the heater. I can’t see any water on the floor when I take the panel off under the wardrobe/cabinets. Can you give advice?
Hi Ron!
The best thing to do is check the plumbing under the shower. There is usually access to the plumbing under the shower. It is possible it leaks anywhere under there and comes out at that cabinet. Remove what you can in that area from the shower to the cabinet and anything else around. Run the shower water into the drain for a while and inspect the exposed areas. The only way to trace where it is coming from is to re create the scenario and trace where it is coming from. Since it only happens when taking a shower, it is best to check the plumbing underneath and also the back of the faucet. There should be a way to gain access to the faucet lines and check to see if there is a leak. Many times the leak can happen at a connection and drip down the line and end up somewhere else so it makes you think the leak is elsewhere. You have to inspect the lines and connections where you can to try and trace the issue.

I recently purchased this RV. It is winterized. This is my first experience at de-winterizing. What do I do to get the antifreeze out and potable fresh water in?
You just need to connect water to either the city water connection or fill the fresh tank and then turn on the water pump to pressurize the system and flush out each water line one at a time. Make sure to do the cold and hot water at each fixture, the toilet and any outside water fixtures as well. It just takes a few minutes really to flush out the whole system. Just run water out until it is clear. Once this is done you want to add water to the hot water tank. Most RV’s have a way to bypass the hot water tank when pumping antifreeze into the system. You don’t need to add antifreeze to the tank, only drain in. Install the drain plug and then open the valves on the back of the tank. These valves can be on the back or you might have a valve in the wet bay or somewhere else. It is best the check the owners manual for the location of the valves as they are different in all RV’s but typically they are directly on the back of the tank itself. This is all that is really needed to de winterize!

Dan

I have low water pressure coming from my fresh water tank. I already put a new water pump but is still the same it start with a good flow of water a go low until die.
Ruben,
There is most likely a kinked line or blockage in the line or tank. It is common for debris to get into the fresh tank and something could have plugged the line or something is kinked. You will need to trace the water lines and inspect them to see if there is a blockage. You should be able to take the water line from the input of the pump and blow through it (when the tank is empty) and if it is hard to blow through then there is a kink or blockage. It can also be past the pump as well. Make sure you are testing this with all faucets as well, it could just be in a certain area. If it happens at all faucets and the pressure is even on the cold and hot side most likely the issue is within the pump area or from the tank.
Sincerely,

I bought this unit gently used…but there wasn’t a owners manual to be found. How might I procure one for this make and model?
Scott,
The best thing to do is check the manufactures website. Most manufactures have an online catalog of all models and an be downloaded. If you wanted a hard copy, you would have to contact them directly and see if one is available. A lot of manufactures are doing away with the hard copies and just send people to their website to view it.

Using gas hot water tank, gas heat & flame cycles ok, tank gets hot, but hot water at shower & sinks is barely warm, pressure out of faucets is same as cold but the water is only slightly warm. Any suggestions: should tank be drained & refilled, could bypass valve be malfunctioning, can tank be vapor locked, etc.?
Most likely the problem is with the bypass valve. If the valve is functioning properly only hot water would be allowed through. If there was a vapor lock on the tank, there would be no water coming out of the hot faucets. Since you are getting good flow through the faucets but it is only slightly warm, it is most likely cold and hot water mixing together. This is usually caused by a bypass valve being in the wrong position or the valve is bad. I would check the valves and make sure they are in the correct position, if they are you might want to remove the valves and check their operation. I hope this helps!

Dan

Water does not coming through toliet and cold water in bathroom sink is barely coming out.Hot water comes out as normal, any suggestions please help
Have already replaced the water valve kit to toilet and water still isn’t coming out
Hi Suzie. It sounds like there is little to no pressure in the cold supply line. You would have to check and trace the lines to see if you can find a kink in the line or a possible blockage. If the cold line ties off of something else, the problem could be there. The toilet usually gets the water supply off of the same line the sink and shower is attached to so if both are experiencing low pressure problems it is most likely the line itself. I would trace the water lines the best you can and see if you can find any obstruction. If you have flex tubing that goes through storage compartments, there could be something laying on it causing a kink or maybe it turned or twisted. If you have PEX tubing most likely there is a valve inline that didn’t open all of the way or somehow some debris made it’s way into the system. I hope this helps!
Thanks

Need to change check valve on hot water
Where would I find the drain plug for the fresh water tank
Help my r v didn’t come with any instruciton 1977 any information would be appreciated
Aqua hot circulation pumps have not been running. Reset them not burner and electric unit are not working. I know it’s most likely a wire. I would like to start by looking at the ground. If i could find it. Help
Hello Kimberly,
I agree, checking the wires would be the best place to start. There will be a terminal block that the wires goes to and they should indicate which one is the ground. Checking all the wires here and checking the voltage would be the best place to start if it is not running at all. Aqua Hot does offer great service manuals based on what model you have and they are filled with great information and troubleshooting guides. I will provide a link to a sample one, these help a lot.

Where do I find the valves to drain the hot water tank?
Hello Esta,
Hot water tanks do not have valves but they do have a drain plug that can be removed. The drain will be on the outside of the tank and near the bottom. Atwood tanks have a nylon plug either to the lower left of the tank or at the lower center if a 10 gallon tank. It is usually a 15/16″ nut (7/8″ aftermarket parts sometimes) and can be removed with a deep well socket or wrench. A Suburban water heater will have the plug on the outside of the tank in the lower center. This is a steel plug and is is 1 1/16″, a deep well socket is best used to remove this one. The Suburban will also have an anode rod attached to it. Removing these drain plugs will drain the tank.
I hope this helps!

I’m trying to winterize my camper and cannot locate the hot, cold, and bypass water valves. I also see only one low point drain (freshwater tank). Where are the low point drains for the hot and cold water?
Hello,
It depends on your RV, most travel trailers will have the bypass valves on the back of the water heater. On trailers or motorhomes with a manifold water setup, there will be valves by the water connections. Some smaller and older RV’s may not have bypass valves. If you have the owners manual, a lot of times there will be information on where the valves are located. Low point drains can be in many places, again depends on the RV. If you can’t see any valves underneath try looking for just open water lines. The valves could be inside. I have seen them around the wheel wells, rear corners, above the termination drain, below the water heater and by the water pump. The can be between the metal skirt and frame but can also be in the center of the unit. Check around the axles as well, they can be hidden there too. On some smaller RV’s there may only be 1 low point for the water lines and some units may have 3 or more depending on how they run the water lines. Sorry I can’t give you an exact location but I hope this helps!
Thanks,

Ticket#17683 RV low water pressure, With a new Rainbird water pressure gauge, I get 30 PSI at water line going into tankless water heater. Pump is rated as maximum 55 PSI. I removed the pump, and removed diaphragm and cleaned, only had one very small pc of white plastic. I had removed the filter and cleaned before checking the water PSI. Could the problem be in the pressure switch on the pump??? If I hook up to water from the house the PSI with limiter on water line is 50 PSI.
Dear Jerome,
Thank you for your patience. In regards to your question-
I would suggest removing the pump and bench testing to see what it gets with a good water supply from a residential hose? If you get a higher psi on the bench test, then you have a restriction in the hoses going to the pump. It could be rated at 55 psi, however if you have a 3/8” water line or it has a kink in the line, you will have low pressure. Otherwise, it could be the pressure switch, but a bench test would verify that.
I hope this helps!

RV Water System
My first time owning a RV with slide outs and automatic hydro levers. Is it recommended to drop the levers first and leveling the RV or sliding out the slide outs.
Hello Richard,
Yes, you should always level and stabilize the coach before extending the
slide rooms. If not, the ground could be unlevel which makes the
chassis twist and then the sidewall. The room will run much smoother
and with less binding if it is stable and level.
Thanks,

How do you winterize the wash machine and ice maker?
Hello Doug,
Proper winterization depends on the type and model of appliances. Splendide is one model that recommends adding RV antifreeze this way:
To winterize your washer-dryer:
1. With the machine power OFF, pour ½ quart of RV-type antifreeze into the washer drum
2. Close the door. Advance the Program Selector knob to a SPIN position
3. Press ON/OFF Button (IN). Wait 1-2 minutes
4. Press ON/OFF Button (OUT). Unplug the washer-dryer from the electrical outlet (or
disconnect power)
5. Turn the water supply faucets OFF. Disconnect the inlet hoses from the faucets. Drain any
remaining water from the hoses.
Finished!
For the Ice Maker Norcold recommends this procedure:
Close the vehicle water supply valve to the ice maker.
Push the ice maker arm up until it locks into the off position.
Remove the garden hose adapter from the water solenoid valve.
Remove the ice maker water line from the water solenoid valve.
-Do not unwrap the water line heater wires from around the water solenoid valve.
Drain all the water from both the water supply line and the ice maker water line.
Put the end of the water supply line, the end of the ice maker water line, and the water solenoid valve each into a clean plastic bag
Use tape to close each plastic bag around the water lines and the water solenoid valve.
Note; If you have an undercounter filter, remove and drain the filter and open the bypass valve.

I went to great lengths to be ready for the winter and installed this CAMCO heated water hose. It didnt even last me 2 months. Now I’m out in SUBZERO freezing weather replacing and re-insulating the water connection. I used the exact hose shown in your picture. I also installed a ZeroTemp hose next to it wrapped in heat tape. That one seems to be holding up.
Valves under shower; only accessible by removing screw on access cover.

When we turn on the bathroom facet it sprays below the sink. What to do?
Lynne
New to owning, excited to experience this life… should you turn on the water pump, only when hooked to water? Is it safe to turn on with only the water in reserve tank? Because when I turned ours on it made a very loud noise thumping noise. I turned the sink water off n haven’t used it since. Afraid I messed it up
Hello Emmitt,
You only need to turn on the water pump if you are not connected to a city or outside pressurized source. The pump will draw water from the fresh water holding tank and supply the rig. When you are connected to pressurized water, it bypasses the pump and provides pressure to the faucets. If it thumped when you started it up, it probably had some line in the air and what you heard was the output hose pressurizing and thumping again the floor or wall? I do not think you messed it up just turning it on even if you were connected to pressurized water?

our water pump seems really loud every time it comes on ,is this normal or a sign of an upcoming problem? we just got this RV and are pretty new to the whole lifestyle. thanks
Hello William,
Welcome to the wonderful world of RVing! Some of the older water pumps are a little noisy, so it depends on the year and model water pump you have. Shurflo has been one of the more popular models and there are some things you can do to quiet them down, depending on what noise you are hearing? If you have hard plastic water lines coming in and out of the pump, Shurflo has a kit that has soft plastic to replace about a foot of line on both sides so you don’t get the “thumping” during start up and shut down. You can also remove the pump from the mounting area and put a piece of rubber or soft foam underneath to cushion the vibration while it is running. You can also remove the pump and check the filter and diaphram for lime and calcium build up. Check out the videos on the site for these procedures.

I recently purchased this RV. It is winterized. This is my first experience at de-winterizing. What do I do to get the antifreeze out and potable fresh water in?
Hi, Carol. We would be happy to assist you; we just need some more information. What is the make/model/year of your RV?
Can you recommend a good travel guide fir driving/ camping the Lewis and Clark trail?? I’m planning a trip for this summer. Thanks. Steve.
First, I’d be happy to talk with your member about their trip. My info is below.
The Lewis and Clark National Historic Trail is about 3,700 miles long (from Camp River Dubois, Illinois to Fort Clatsop, Oregon), so there are lots of places along the trail where people can connect and see the sights and experience the history of the Expedition. I’d recommend that they start with a phone call to the Trail’s headquarters in Omaha — 402-661-1804. Until the end of April, they’re only open M-F, 8-4:30 CDT.
Their website is http://www.nps.gov/lecl When they call, they want to ask for a trail brochure/map, which gives a good overview of the history of the Expedition, all the key dates, etc. On the back is an overview map of the entire trail, with key sites along the way. Of course, most of the trail is the Missouri River, but there are lots of roadways that follow on one side or another of the river. Then on the western side, much of the Trail follows the Columbia River.
On the website (under Plan Your Trip, Directions & Transportation), are several “Story Maps” — interactive maps which tell the different stories of the Expedition — Animals, Plants, National Historic Sites, Water Trails, Volcanoes, etc. These are great planning tools, especially the Interactive Trail.
If they’re starting at St. Louis, they should know that the St. Louis Gateway Arch and the Museum underneath in the Jefferson National Expansion Memorial are both being renovated. I think the tram rides in the Arch will resume in late April. Not sure when the museum will re-open. Some of the items have been moved to the Old Courthouse nearby. The movie “Monument to the Dream” is being played somewhere in the complex. Some of the other sites, especially in the Dakotas, Montana and Idaho, may not have regular hours yet until April or May — they should check in advance. There are so many sites along the Trail, that it’s nearly impossible to see them all — some are NPS operated, but many are state, local or privately managed. The Trail is essentially a giant “cooperative” of organizations, all preserving the story and history of the Expedition.
The Facebook Page has lots of posts about the historical aspects of the trail and some of the sites. (www.Facebook.com/lewisandclarknht/.) We post almost every day, at least once (usually at 7:00 a.m.). There are some interesting videos on the page, too (Videos tab on the left).
There are several books on traveling the trail — “Lewis and Clark Road Trips” by Kira Gale (awesome and detailed), or “National Geographic Guide to the Lewis and Clark Trail,” as a few examples. There are lots of others, too, focusing on everything from hiking or biking the trail to canoeing it. If they have the time and interest (and haven’t already read it), the best complete overview of the Expedition and all the characters is “Undaunted Courage,” by Stephen Ambrose. Or if they prefer videos, I’d recommend either “Lewis & Clark: Great Journey West” by National Geographic, or “Lewis & Clark: The Journey of the Corps of Discovery,” by Ken Burns.
Hope this is helpful. As I said, they’re free to give me a call if they have any specific questions. I’ll try my best to help.
Also, Forgot one thing…
They may enjoy reading a blog that a friend of mine has started: http://www.crazyguyonabike.com/doc/18889. He’s retiring next month and will be bike riding all summer from NJ to Camp Duboise, IL, on the “eastern” portion of the L&C Trail (at this point, it’s still not an official part of the Trail), then picking up the “official” current Trail in St. Louis and riding to the Pacific.
His name is Kent Schlawin. If you would like to contact him, send an email to: kschlawin@icloud.com
Not long after hooking up to a camp’s fresh water supply, I notice a steady flow of water coming from just in front of the right rear wheels from an inboard drain of some sort. It is not the A/C water drain, but after a night in the camp, my parking area is soggy from all the water draining from this spot. Should I not be using the pressure water but only the onboard water pump?
Hi, Joe. If you have water coming out the underside from a drain, it’s more than likely a water tank drain, typically a 3/8” pipe coming down through the floor designed to drain a tank. Locate the drain and go inside and there should be a shut off valve, either a lever valve or a pull valve with a metal ring that will push down or pull up and this should stop the leak.
Our r v water fill is by an actual valve just like your city water valve. Can you give me any ideas how to add the bleach and water to clean tanks as we can not just pour this mixture in like most r V’s do. Thank you.
To sanitize black and gray water tanks, simply pour the solution down the toilet and shower drain. For fresh water I use a garden hose that I cut off the male pipe thread end at about 24” and insert a funnel in the open end. Check to see how far inside the compartment your valve is to determine how long to cut the hose. Screw the hose into the valve, insert the funnel, and start pouring. Your connection should have a “check valve” but it’s designed to keep water from coming out when the on-board water pump is running and let normal water flow come in.
