Do I Have a Bad Water-Fill Check Valve???

Here is the scenario: I was filling the water tank in my MH (Fleetwood Expedition, 2013). When the tank filled (water comes out the un-capped gravity port), I shut off the town water (at the faucet), then turned the bypass valve on the MH from "fill tank" to "bypass", then disconnected the hose from the city-water supply connector on the MH. For some reason (I have not done this before), I decided to turn on the water pump from the outside switch .... and .... water starts actively pumping out of the city water supply connector on the motor home! Hmmmmm.....I re-rotated the tank fill lever to "fill tank" then back to "bypass" just to make sure I had done that correctly - but when I started the pump, water once again started being pumped out of the city supply connector.

Now, upon reading the instructions, those instructions specify a different order of activities (compare to what I did above, as this is different): 1) when tank is fill, turn the bypass valve from "fill tank" to "bypass". 2) turn off city water. 3) disconnect hose from city water supply connector on MH.

When I did things in that order, everything was fine, and I had no back flow from the fill connector.

The question I have for you is this: is this order of steps really **THAT** important to correct functioning of the check valve behind the city water supply connector - or do I likely have a bad check valve??? (this unit is ~ one month out of the factory....)

Doing things the "by the instructions" is a pain, as the connector remains pressurized, and it is a problem getting the hose disconnected from MH (difficult to turn, lots of water squirting around, etc.....).

Thanks in advance for your thoughts.

Hi MN_Traveler,
I agree with you about not needing that specific of a process. However, I do not own a Fleetwood product. There may be something special requiring the process be followed. Consider posting this question in the iRV2 Fleetwood Product Owners Forum. If you go to the iRV2 main page and scroll about 1/2 way down, you'll see the Owner's Forums. There you'll find the forum for Fleetwood products. The real skill to answer your question is, most likely, in that forum.

I have a 2000 Bounder & had a somewhat similar problem re. leaking out of city water port. When I energized the water pump, water from the fresh water tank would "pee" out of the city water port. Found city water check valve to be bad, delaer replaced it, no problems now.

Most of the city water inlets I'm familiar with have a spring actuated check valve. When mine leaked a little, I just use my thumb to snap that little rod/spring thingy until it stops. When it got to be that that wouldn't help, and I had a water pressure gauge already, I just put quick connects on everything, snap on the gauge when necessary and off when connecting a hose.

I have purchased a new check valve shore water connector and I'll get 'round to installing it...someday...

In your case though, it's not uncommon for there to be plastic cuttings floating around the water system of a new RV. Water pressure and flow changes move them around a bit. I would think that it's just some flotsam floating around near the city water inlet rather then a procedural error.

Thank you all - I will keep an eye on it (including whether there is anything I can "snap" or otherwise coax back in to position! :-)

Check valve is probably leaking. Just buy one of those plastic hose shut off valves or a plastic plug and screw it on the connection. A quick cheap fix.

On our Expedition, i don't follow the instructions you were given, and have never had a leaking problem. I suspect you might have a check valve problem. I don't think debri would be the problem because you said when you follow the instructions all works fine. I would think debri wouild cause the leak all the time. I don't understand why following the instructions would change the working of the check valve. when you build pressure behind the valve, it should push harder on the valve, and force it to close I would think.

I filled my tank and proceeded on a 215 mile trip. When I was 40 miles from my destination I decided to turn on my water pump. As I was driving I looked in mirror to observe a big water trail being left. I stopped and found that water was pouring out my inlet valve. In about 5 miles I had lost over half of my 75 gallons out the inlet. When I got home I found debris was blocking the round ball inside the valve. I used my wife's knitting needle to remove the debris. I reinstalled the valve and turned on the water pump and it is working fine. I am going to order a spare just in case I have the problem again.

Those city water check valves are pretty low quality devices, what I did is install a 90 degree fitting on the inlet (mainly to route the hose down instead of horizontal) the got a shutoff ball valve from Lowes or Home Depot and attached it to the 90 degree fitting. It stays installed all of the time, when to hose is not connected the valve is closed... No more leaking check valve...
