Wierd Water Pump Problem on 2009 Rockwood

We have had our 2009 Rockwood since May, we have used it about 5 times since then and everytime we have connected to the city water inlet.

For the first time today I decided to try the fresh water tank system. I filled the fresh water tank, and then opened all of the cold/hot water faucets, and then turned on the water pump.

When the pump is running it gushes water back out of the city water inlet!!!

Anyone ever had this problem??

You might need a new check valve. Search for the post that talks about reseting the seat too. Alternatively, you can just screw a valve into the city inlet and shut the valve in a pinch. Lot's of people had this problem. It is a $10 part. See

or just get the check valve: for 1/2" and for 3/4"

EasY! Some owners just screw on a 3/4" hose plug. If you're gonna dig into there modifying the lines, consider putting in a permanent winterizing kit if you don't already have that set up

Do you think that it might be the order that you did that in? I think I would try pumping up pressure on the system until the pump shuts off first, with all your faucets closed, then open them individually to flush them out. The check valve mentioned probably needs that pressure to seat it closed. I switch back and forth with water supplies, and haven't had any problems. P.S. be sure that you pump up pressure on the hot side before turning on the water heater, oryou may burn it out!! Randy

As Turbopuppy said, that's a common problem. The most common thing that happens is when winterizing, people push in on the check valve in the city water fitting and it pops out of place. Once in a great while they can be repaired but most of the time replacement is required. Some people just by a hose thread plug and plug the inlet when running on the resh water tank.
