RV Low Hot Water Pressure or No Hot Water Pressure Water Heater Check Valve May Be The Problem.

So you wake up to low or no hot water pressure but the cold water is fine.
I found our problem was with the Check Valve located on the back of the Atwood water heater.

Another terrific video. Thanks for taking the extra time to share your knowledge. Your videos make me a better RVer.

Thanks for the kind words. Its comments like your that encourages me to take the time to make them.

I’ve got the posit of your problem I have lots of hot water pressure little to no cold pressure

[@michaelbusch1575]

Did a lot of time looking at stupid videos until I came across this one. Solved the problem immediately! Thank you for the info -- this video should pop up first from now on!

[@ktoutdoor]

Yes I agree 100% and thank you for watching and have a blessed day.

Super clear. Pro advice. The suggestion on the extra wedges and boards is solid too thx. ‘Bout to tackle my check valve and it feels darn near welded onto the tank! 😂 Edit/update: After removing the heater core, draining the tank several times, removing the check valve core, reinstalling the check valve…. Etc etc etc…. Turns out, the liner of the city-water hose has eroded away somehow and has become clogged. Time to replace a very long stretch of hose. Fingers crossed, this is the final fix! Might have to figure out a backup plan if this doesn’t resolve the problem though. 🤪 I thought it was a clog in the camper lines or the check valve, but never thought to check the water pressure on the main-line…. Good at the tap, terrible at the end of the hose… Edit edit: Hose replaced. Problem persists. Literally mid-shower and the hot water abruptly shut off to a trickle. 🥶 Cold water supply runs fine. I’m stumped for the moment… Okay. Okay. I just rewatched the video and my spring is totally missing now too…. I’ll go buy a new check valve today. Ugh…. At least I have all brand-new drinking water-safe hose!

Great video, had the water pressure issue and googled it, your video came up 1st and it saved me probably hours of head scratching. Thanks!

Thanks for the help. I’ve got the same problem. Check valve.

[@banjeauvi7321]

This fixed my problem. Check that anode also folks as it puts debris in the tank as it does it’s job.

Great video ,that valve fix our problem. We had to dig out the spring so i'm glad you showed that spring sitting in the water heater.

My brother-in-law is asking me to come and see why his new trailer doesn't have hot water now even though it worked yesterday.. glad I found you as I had no idea this was here.. I will be checking this tomorrow. Thank you!!

Was your problem the check valve like ours?

[@toddlawson3027]

Kevin! THANK YOU!! I just had the exact issue all of a sudden. Your wonderful video explained and showed how this check valve was the problem and how to fix it! It is late at night now, but I will check mine first chance I get and I feel confident that this is the fix!

[@ktoutdoor]

Thanks for watching. Have a blessed night my friend.

[@stanleyknauff7337]

Excellent video! I have a Winnebago Journey 34Y in a campground with no hot water pressure. Per your video I'm sure the check valve is the culprit. I'm waiting until we're home in 10 days to tackle replacement. I'm hoping to get all needed access through a panel in our bedroom closet (where the water heater bypass valve is). Thanks for the excellent video!

[@ktoutdoor]

Thanks for watching. Have a blessed day.

[@stanleyknauff7337]

Kevin, Status update: it's fixed! When we got home I got the old check valve out. (Very difficult. Had to buy a 1" socket and a 20" drive extension for access with any leverage AND I used a 3' length of pipe over the wrench handle. With practically all my body weight on all that, the check valve finally broke loose with a very loud crack. I was relieved that I had not broken it off in the water heater.) The condition of my old check valve was just like yours. I even found the loose spring in the water heater as you did. I bought the same replacement you did. I installed it today and now have hot water pressure (and no longer have the groaning, whining noise from the water heater that had become increasingly louder)! I'm sort of proud of this DIY project and especially pleased with the $$ savings -- with my local go-to RV repair facility's labor at $130 per hour. Once again, I thank you for your excellent invaluable video. -- Stan

@@stanleyknauff7337 Thanks for the update Stanley glad you was able to fix it yourself!! Don't it feel good.

Thank you thank you thank you !! My camp trailer is doing the same thing with low pressure on hot water. I’ll attempt a fix in a few days.

Let me know what you find. Thank for leaving a comment.

[@sprdoorman4182]

Hi Kevin, Great video since I had the same problem on my Itasca 35G. Took off the access panel on the back of the cabinet and valves were right there, but still a little difficult to get to. Took the hot water side check valve off - had to use an open end wrench since no room for a socket on mine. Sure enough the poppet was loose and the spring and retainer were gone. From what your video showed, I got a mirror and looked down into the hole in the tank and I could see the spring and the retainer down in there. It was a bit deeper in there than yours and I tried to use a wire to retrieve them, but didn't have any luck. Then I thought about using my Shop Vac to see if I could suck them out. Made sure the drain plug was out and the relief valve was open so air could get into the tank, applied the shop vac and instant success! Glad I watched the video or I might not have looked down in there for the spring and retainer. I suspect they might have still produced a restriction in the line after replacing the check valve. Thank You!

[@ktoutdoor]

Thank you for contributing that was a great ideal using the shop vac. Thanks for watching and have a blessed day.

I make a habit of putting 25 quarts of vinegar and 25 quarts of fresh water once a year and run it through the water system, leaving it sit in the lines for a couple of days. Really cleans the piping, valves and tapes, and helps with the grey/black tanks get clear. Yes, everything fizzes like crazy.

[@ktoutdoor]

Yes vinegar is a great cleaner I buy it by the gallon. Thanks for sharing.

I had zero flow on hot, even in full water heater bypass….the seals in the in/outlet valves slipped into the ball valve flow path and cut off flow.

Thank you for contributing

[@robthompson343]

Thanks for another great detailed video. I have great pressure in the bathroom but very low pressure in the kitchen. Any ideas?

[@ktoutdoor]

Is the low pressure equal on both the hot and cold side ? If so try removing the aerator from the kitchen sink

[@elizabethkinsey5745]

Already had to replace mine. The hard way.

[@joesmith-fi1sx]

im trying to think how the check valve prevents anti freeze from filling the water heater ? i dont get it. the check valve seems to be where hot water come out of the tank to the rv. i just took out my broke check valve as it was broke and all the sudden i stopped havi g hot water coming out so i removed it and now its back in action. now only thing is a problem iv had since getvthe rv. very very low water pressure hot and cold at the bathroom sink only. i dont get what it could be except it is the highest spot for water to come out in the trailer but doesnt seem that would be it. everywhere else there is decent pressure great video

[@ktoutdoor]

Have you tried removing the aerator the screen may be clogged. Is this a new or old faucet?

[@roberttaylor8261]

Will the hot water side of faucets still have good pressures but only cold water? That’s my problem? Tank has hot water but faucets are cold with good pressure? The nautilus valves are all set in correct place for city water?

[@ktoutdoor]

1" socket worked for me.

[@stephanieg3423]

@@ktoutdoor thank you for replying. Been so busy trying to get things done before the next snow that we figured it out during prepping. We had a frozen pipe. Not sure where but we believe it’s between the water heater and the first bathroom. Whenever the pipe freezes it shuts off the hot water through the whole RV and all the water to the half bathroom.
