City Water Check Valve
Our 2009 city water check valve is occasionally sticking shut.   I think I remember someone saying that it’s easier to simply remove and replace the existing check valve BUT not the eternal part screwed to the sidewall.  I’ve heard that the external part is strongly attached as only the Factory attaches things.   I’d like to avoid that struggle.   Does anyone remember anything similar to this repair?

Thanks in advance.

Do you have the model number or link to the part you bought?  I just ordered one from Amazon hoping it’s the right size.

Amazon.com: RV City Water Inlet with Check Valve, RV Water Fill Inlet...

How did you remove the original one?  Some heat and gentle prying?

And thank you Bob.

That’s the article I read a long time ago.  Perfect and thank you.  I’m inclined to replace the entire fixture based on what Bob posted above.  Margee will be my helper and she has incredible patience.  The harder the project, the more determined she becomes.  And hammers or brute force are NOT her style.  So we’ll see how this goes.

Hi

To remove,  I first removed  the 3 screws.  Then using a stanley knife I carefully  cut around  the outside edge  did not want to have

paint chip.  As I did this, I carefully  lifted the valve  away from the frame,  valve removed easy from interior water line

I do not have info from whom I purchased valve

I replaced just the inside parts, as described in the article.  Once you figure it out, it takes less than 5 minutes.

You could try replacing just the inside parts, and then move on to replacing the whole assembly if replacing the insides proves to be unsatisfactory.

Ed & Margee, IF you replace the entire city water connection, keep in mind that you will now have a white city water port instead of one that is color coordinated to match your rig. Not a look I wanted...

I was one of the contributors to the article posted on  "The Companion". The repair that is posted was recommended to me by someone at the Lazy Daze factory. The repair is much easier than it reads if you have the parts in your hand.

Thanks Steve.  Our city water valve is Oxford white and the replacement is white.  If it doesn’t match, I’ll probably do the fix as you described. We’ll know in a few days one way or another.

We’ve carefully reviewed the guidance in The Companion and several YouTube videos that showed us how to remove and install just a new check valve.  So now I understand how to do that. 

Edited on 9/23/2023 - After more consideration, we plan to remove just the old check valve as recommended above and install a new one.   If the new check valve is not an exact match, then we may replace the entire fitting.  I didn't want to mess with removing the old fitting which might damage the paint if I was a bit careless.  I may also post the results if I haven't worn out this topic!

This video seems to mirror the directions from The Companion.

We finally replaced just the city water check valve this morning.   Everything seems to work when I turn on the water pump.   I haven’t tested it with a city water connection which will probably be when we’re on the road. 

I couldn’t see why the old valve wasn’t working which has me wondering if we’ve actually fixed anything.  Time will tell!

I permanently prevented any future City Water connection leaks twenty years ago by installing one of these in the City Water inlet
Amazon.com: Camco 22103 RV Plug with Lanyard : Everything Else

Our LD has never been subjected to the dangerous pressure surges of city water connections, instead, we use only the onboard water supply and water pump. YMMV

End of story … we hope.

The replacement check valve in the city water connection seems to have resolved the problem.   Or at least for the last 3 days.   My best guess is the spring in the old check valve was weak since the plunger and o-ring seemed fine. Who knows?

Destination:   We highly recommend Lake Bob Sandlin SP near Pittsburgh, Texas.

Now what?   We are having a second cup of coffee, listening to some of our favorite music,  looking at the lake out the back window while sitting at the dinette table.  Our To-Do List 📋 is once again empty. 

We’re feeling very grateful.

Thanks for your discussion on replacing the check valve. I just finished doing the same. I used a nut driver on both the inside where my wife held the plastic tee in place while I installed the spring and used another smaller nut driver on the outside to install the disc. It snapped into place and it works. I also feel it was a weak spring and not the washer but I replaced both.

Hello Kevin.   Using a nut driver was a nice idea which I’ll have to remember in the future.   I’m glad I didn’t replace the entire city water fixture but just the check valve.   Keeping repairs simple always seems like the best solution.
