No Hot Water! Replacing
a Bypass Valve
 Early in the morning, after a nice, long, sweaty
walk with
the puppies, I decided to take a shower. Lo behold, no hot water!
Nothing came out when the hot water was turned on. Not a drop. The
cold water worked fine. I traced the water lines and found a suspicious
looking do-dad hanging out of the back of the hot water tank.
Disconnecting the pipes revealed it to be a check valve. I removed it,
popped up to the local RV shop, and about $5.00 later I had a working hot water
tank.
Another Failure!
Oh for crying out loud. A couple years later
the replacement failed. Both the original and the replacement had
one thing in common. They had plastic guts. An end piece and
spring fall off and into the tank. I've now put the third check
valve in. This time it is all brass. Let's see if that might
work better. For now, insure your replacement is all brass.
