No hot water pressure, cold water pressure fine.
« on: July 22, 2019, 07:03 PM »
I wasn't sure where to post this, because it fits in plumbing AND appliances, so I decided to put it here.



Today, the hot water stopped working.  No water pressure at any faucet when turned to hot (not even the shower fixture), but normal pressure on cold.  After doing some research and troubleshooting, it turns out that it is the "check valve" on the back of the water heater.  Thankfully, I can reach it from inside to replace it.  I'm going to replace the Flair-It bypass valve while I'm at it, since it has a very slow leak from the shutoff handle.  So tomorrow morning I'll drive down to the RV parts place and get another check valve.  Fun fun fun!

It was definitely the check valve!  It wasn't easy to get to (I had to pull the converter out enough to access it...thankfully Winnebago made the wires going to the converter long enough to pull it out the required 8 inches or so), but the new one is in, and all is well in the universe!  That hot shower felt great yesterday!  I also replaced the shower fixture...and the hot water heater bypass valve while I was at it, since it started dripping when I turned it to troubleshoot the system, and wouldn't stop.  I used a Flair-It three way valve.  Works fine now, and no leaks.
