    My unit is a 2017. At first I had plenty of hot water but now, not so much. With out spending money that I don’t have, how can I get more hot water coming out. Thank you Ben Out.

      Dear Benigno,

      Thank you for your patience. In response to your question-

      The water heaters have a set temperature on the thermostat. There is no adjustment that can be done to make more hot water come out or to change the temperature. The problem is more likely the heating element is bad or the flame is not set correctly when trying to run on gas. You could also have a bypass valve in the wrong position on the rear of the tank or one of the valves is bad. If you are still getting hot water but it doesn’t feel like it is much, most likely it is a problem with the valves but I would troubleshoot everything else as well. We do offer some great troubleshooting videos, I will post a link below to them.

    We bought a camper with a broken plastic plug , I used an easy out for pipes it came out very easy. The people had tried to pound in a big screwdriver but that didn’t work.

    When this happened on my plastic plug, I heated a 1/2″ socket extension, melted it into the plastic hole, cooled and turned out the plug.

    Rather than risk damaging the threads on the tank when removing a stubborn plastic drain plug, I have found that drilling out the center of the plastic plug and heating an old screwdriver with a propane torch works well. Laying the hot screwdriver against the drilled out hole quickly melts the remaining plastic plug down to the metal tank threads without damaging the metal threads. At that point it is relatively easy to pry the plastic plug loose for removal.

    first thing I did was get rid of plastic drain plug. Installed short galvanized nipple and connecter a short steel braided toilet supply line with a shut off. Makes for easy draining and gets the water out of the cabinet space. And no more drain plug.
