How to Fix Your RV Water Pump Check Valve

If you wake up to see water dripping from your freshwater tank, you may fear that you have a leak and an expensive repair on your hands. However, you might have an RV water pump check valve problem instead.

Most of the time, this is an easy fix. So let’s take a closer look at how to fix your RV water pump check valve so you can keep making memories at the campsite.

Thankfully, fixing the water pump check valve isn’t a timely or costly repair unless you have to replace the whole water pump. Let’s examine a few ways you can fix this common problem.

If you cycle the pump and use it for a while, the check valve can correct itself. This is the best-case scenario for fixing your water pump check valve.

It requires unscrewing a few screws to remove the water pump and then taking it apart to get to the check valve.
