Water pump keeps running

July 07, 2022, 10:42:45 pm

My 2006 Affinity water pump runs all the time.  I suspect a faulty water pressure switch or something of that type.  Does anyone have a picture of the water pump pressure switch?  I hear it's easy to replace but in my coach it seems difficult to get to.  When I open the access panel. there are too may parts in there.  Thank you.

We recently purchased our parents' 2007 Intrigue, and the water pump was running for reasons unknown as well... then it stopped... we thought all was well, and we started doing work on the interior.

My wife was curious about the laundry machine in the coach, and opened the door...
...at which point we discovered where all the water had gone.

Doing a Google search, I found that apparently the solenoid-activated valves for the Splendide washing machine sometimes fail. So you might want to be careful if you have a washing machine in the rig.

All the RV water pumps I've encountered (not that many) have the pressure switch integral to the pump housing and not a service item. Maybe yours is different?

Is it possible you have air trapped in your system? If there is a lot of air the pump will struggle to keep water pressure. Try running all your hot and cold faucets/shower etc until they run smoothly. Don't forget the outside faucets. That should get any excess air out of the system. It's always worked for me.

I replaced the pump with the same model.  It was easy but the access to that bay was hard.  Thank you.

Look for the allen screw on the top of the pressure switch. Turning clockwise will result in a more sensitive switch (more likely to cycle) Turning counterclockwise makes the pump less likely to cycle. Use your shower and determine when the pump cycles.

This worked on my pump.
