Fresh water tank is filling from city water

[RHOUSER]

I have tried the shut off city water, relieve pressure. Turn on water pump. Run water to sinks from freshwater tank for awhile. Turn off pump. Turn on city water.

Drained fresh water tank.

It refills. This started today. The water pump was on with the fit water on. It overfilled the fresh water tank.

Any other tricks to reset the check valve in a 2018 FR 2501 TS?

Thanks. rch

unhook from city water to relieve the preassure. turn the pump on and off a few times while opening a facuet and it should reset unless its stuck and need to rebuild or replace

Even if you do reset the valve built into the pump chances are it will happen again when someone forgets and turns the pump on while hooked to city water.

Here's a pretty much permanent solution for $9

This check valve is designed to be added between pump and inlet screen or suction hose and inlet screen and it will allow water to be sucked in from tank but not flow back into tank.

Depending on your installation it may be necessary to add a 1/2" NPT Street Ell (female on one end, male on other, making a 90 degree bend).

Due to the direction of flow and orientation of male/female threads it can't be added to the pump outlet unless adapters are used. (a couple of 1/2" close nipple and a 1/2" coupler.)

When connected to city water, the water pump should be off. Re do the procedure above and keep water pump off.

This subject comes up about three times a week and there is a ton of material on this forum repeating the problem and solutions over and over, ad nausaem. You can often save yourself a lot of time by using the search function.

When I read thread titles that appear to be old topics, and I have no interest, I just don't read therm.

Yes, one can use the search function but not everyone is adept at finding the answers they are looking for by doing so.

I put one of these on my Rockwood 2902WS but I put it on the outlet side of the pump instead of where water comes in to the boondocking pump. I stils had some water in my fresh tank a couple of weeks ago.

Is the check valve between pump and point city water enters the system?

Also, you mentioned "Boondocking Pump". Do you "boondock"? If not, and don't use the water pump (traveling with an empty tank) it's possible the valve is backwards.

If you put it on the outlet side of the water pump you should have installed a close nipple in the female end and a coupler on the male end which reverses the way it's attached to the pump but allows for the correct direction of flow.

Water in this check valve flows from male threaded end to female threaded end.

Something to check. If all is correct I'm surprised as water is making it past two check valves.

Of the 4 rvs I've owned since 2011, one them, not sure which one, had no gravity feed fill for fresh water. Only way to fill FWT was to hook up to city water and open a valve under the sink. When water started running out the FWT overflow, I would turn off the valve under the sink. The valve under the sink had an oblong silver handle, like you see behind a residential toilet. Of those 4 rvs, 3 were Forest River, and one was a KZ. It may have been the KZ. DW gave me so much grief, deservedly so, about trading every 2 years, I don't have much butt or memory left to work with.

I had the same problem with our 2018 2401ws. I installed the check valve to the pump inlet side and has been working great.

If your memory is bad are you sure she wasn't hitting you over the head instead of chewing/kicking your butt?


My wife used to tell me I could buy anything I wanted but to just remember, she had the checkbook. (but maybe that's why I was able to retire at 61).

The problem is when one does a search they get to see posts from 3-4 years ago along with other posts and advertisements that Google comes up with. Other forums I view have it set up so when one enters a search the only thing shown are posts in that forum. Nothing from anywhere else.

And, they are always shown sorted by date with the newest posts first.

So, searching is a tedious process with this forum and pretty much a waste of time.

Yep then try it on the app.. Even worse

The problem often is that this site has two SEARCH's. One is right above the "WELCOME YOURNAME" in upper right, and the other is below it.


The one above searches the internet. The one below is what should be used to search just this site.

Interesting. I never noticed that before you mentioned it. The top one is the one that really stands out so it’s logical that most would go there. It needs to go away.

The one on the top has a toggle. One pick is for FRF and the other pick is for Google.

True, but with it on FRF you still get very outdated results followed by Google results.

Are you using a pressure regulator? If not get an adjustable one and set to less than 50 lbs which is about maximum for you TT water pump check valve. This solved my problem when my tank was filling up. campground water pressure varies depending on where you are in the line.

I'm not one to berate people about searching but the lower search button allows filtering by specific forum. That may reduce the resulting noise.
