Water fill issue
I have a 2018 keystone cougar ht 32rli,water connect is in a docking station,when i turned water on to city water,it filled my fresh tank,2 people told me that behind the city/fresh valve there is a check valve,that is bad,and is preventing it from switching over.Went to camping world where it was purchased from,the servive tech said that it is the water pump.He said there is no diverter
from the inlet connection to the water pump.Called keystone customer service
she said im not a tech,but its the pump.Stopped at another dealership,the service tech said it is the check valve from inlet to pump,that diverts the water
flow. the pump worked fine using the fresh water,there was not back flush,which camping world said it would come out the inlet line.
Any ideas,who do i believe???????
thanks

If your trailer is like mine, where you connect the water hose there is a lever that moves 90 degrees. One position is “city water” that supplies the trailer and the other position “tank fill” allows the water to fill the fresh tank.
When on city water, the inlet line is attached to the trailer plumbing just AFTER the water pump. There is a check valve in the pump that is supposed to stop water from filling the fresh tank.
When on tank fill, the water is routed to the fresh tank.
You may have a failed O ring in the lever and/or the check valve in the pump has failed. If you can get to the back of the lever, you can test the valve.

With all your valves in the proper positions and you are still filling your fresh water tank, the check valve that is built in to your water pump has failed. You either have trash in the check valve which is keeping it from closing or the valve is just bad. On some pumps, you can remove the check valve and replace it or clean it. The quickest way is to just install a new pump. Either way, you should also install a screen on the tank side of the pump which will help to prevent this problem in the future.

I have the same water fill issue
My tank is filling on city water in my 2020 29bhs, so I took the blue handle off and took off the 4 screws that hold what I think is the valve. I’m attaching a picture of it to verify this is the part that needs changing. Am I on the right path? Is my other picture a correct replacement part? Many thanks in advance.

I would swap that out for an old fashioned gravity fill and eliminate any possible leaks in the future.

That very well could fix your issues. Often times the O ring fails. You may be able to find a rebuild kit.

I have the same model as you do - a 2018 32RLI. Each of the people you asked might be right. Some campers have a check valve that keeps water from the City feed from accidentally going into the tank. Neither you or I would know unless we take things apart because there's no documentation from Keystone. All campers have a check valve that's part of the water pump. Again, unless you can get the damned thing out from under the end table, we'll never know.
I don't currently have that problem, but if you ever find a solution, please let me know for future reference.
In your docking station you have a threaded inlet for the black tank flush. You can use an ordinary hose from wherever you're getting water or you can hook up one of the "slinky" hoses to the funny looking push on adapter for the outside water connection.
Let me know if any of this helps!

I'd be wary of buying a "Keystone Part" from an Amazon seller named "Keystone Meats."

HA! Not if you have my gravity fill! My old $25K less Passport had a better gravity fill than my new Cougar does, hands down.

I don't have a lever to shift but I've had this happen on 2 occasions in 5 years. The fact that I don't use the electric pump enough could be the problem. It had something to do with the check valve not closing off. I found a video on YouTube to correct this issue. I exercise it at home so I don't have to deal with this problem at a CG. My2cents.
