Water Heater Bypass

#1
We had a bypass installed on the water heater when we winterized this year. Now we cannot seem to get hot water in any of the sinks or the tub. There is hot water in the tank and the pilot lights. How do we get it flowing through the coach again?

Re: Water Heater Bypass

Hey Pioneer, welcome to the forum. You should have a lever/switch where they installed the bypass kit. Throw/switch it in the other direction.

Hey Pioneer, Rod (730) is a RV technician so turn them both. I only have 1 lever on my RV bypass. Hope that fixes your problem. :)

DL ,, i was posting that most rv's (mine included ) have a vlave for the bypass (aftermarket installed) and also a main WH valve ,, but some other rv's may be different ,, i myself found out about the second valve ,, which i did not know i had ,, till the Water was warm but not hot ,, but the tank was hot ,, do did some poking ,, and ,, yep anouther valve ,, i look around on other rv's that i service for this type of thingy ,, and ,, yes i have found more than a few out there ,, this comes from my personal stupidity ,, so chalk it up to rv learning 101 ,,, :blush: :laugh: :laugh: ;) :approve: :approve:

I believe even after owning these things 10 years we'll find a valve, switch, fuse, etc that we never knew was there.
I still haven't found my antennae amplifier
and the cable to pull to drain the air tank.

Re: Water Heater Bypass

Rod, my trailers have 3 valves. That way you don't need a check valve that could go bad.
The systems with one valve will have a check valve in the top entrance to the tank. That check valve is how one valve can work.

In a 3 valve system, you have a valve in the top and bottom water lines that feed the tank. Then you have a cross tube, before the other valves, with the 3rd valve in it. During summer usage the cross tube valve is closed and the other 2 are open. that forces water through the heater. When you winterize, close the top and bottom valves and open the cross valve. That lets anti freeze by-pass the water heater.

I like that system better because I have changed a few check valves and it is not fun.

Re: Water Heater Bypass

My system must be a check valve type. It stopped working a few years back. It is clamped on the plastic tubing so I haven't ever replaced it.

Re: Water Heater Bypass

Rod,
If you have 3 valves, you do not have a check valve (back flow preventer). One valve, you have the check valve in the top water line. Two valves, I have seen with and without the check valve.

I was trying toattach a picture of the back of a waterheat with 3 valves shown.

Icould not getitattach here. I was able to loadit in my album under the "Album" link at the top. Go there, click on Grandviews album and you will find it.
