water tank overflow

[JumpinJack]

Has anyone had this , I have 2019 RR26 water tank over flow while connected to city water hook up ? Called dealer says it is bad valve in water pump. So I capped of one side of pump. Dealer says this is a common issue with these pumps. Curious how many others had this prob. Also rather than have a dealer fix this , where is a good place to purchase the pump ?

This is fairly common but usually can easily be cured.

First try this..... Turn off your city water. Open a faucet to let out the pressure.
Turn on your water pump.
Open a faucet and close it so the water pump cycles off and on several times.
Now turn off the water pump and turn on the city water and see if the fresh water tank is still over filling.
Often this procedure can help flush out a tiny piece of debris that is stuck in the water pump check valve.
As a last resort -- if your water pump is easy to access, you might try removing the end cap and checking for anything stuck in the rubber diaphragm.

Follow Dan's instructions and you should be good to go. Sometimes it take a couple times to get it working. YES ! this is a common problem and you'll see posts almost weekly on the subject.

One other option would be to install a check valve in the hose on the inlet side of the pump.
