It may not seem like there would be a lot maintenance required on the RV waste valve that flushes out any waste-water that builds up in your RV, but regular maintenance is in fact very important for ensuring a clean and stable waste system. Dave Solberg teaches you a few of the basic tips and techniques you can use to properly maintain and protect your RV waste valve.

The RV waste valve is one of the RV’s simplest components, as it is made up of a standard sliding valve and knob system, but it is also very easily damaged and stuck. That’s why it is necessary to clean and replace any parts on the RV waste valve that are aging or stubborn.

Dave recommends applying silicon to the shaft, rather than WD-40, which will clean the grease and rid of the natural oils that help the valve slide fluidly. Likewise, to prevent gunk buildup and maintain pliable seals, you can pour vegetable oil down the drain and allow it to coat the RV waste valve. Companies such as Thetford have also manufactured a lubricant that you can use instead. All it takes is a quarter cup to completely coat the RV waste valve and effectively seal it for your next big road trip.

It’s also possible to replace parts on the RV waste valve such as the handle and shaft, which are more likely to chip or break off on trailers because they’re exposed to tire shreds and dirt. As is the case with most minor appliances and smaller components on an RV, you should be sure to thoroughly check over the waste system before and after a long drive. It’s better to be aware of any problems while you have a service shop nearby than to have to scramble to make a fix out on the road.
