Hot water heaters

The hot water tank heats but can't get hot water to the faucets.

Where is the water heater check valve/discharge valve

Some of the water heaters came with bypass kits and some people added their own. You may need to check the back of your water heater to see if you have a bypass setup and it is set correctly. If you can take pics and post, some of the knowledgeable folks can tell you. I thought I had some pics but can't find any right now. But you should be able to search the forum using the custom search (link below).

Hi,

Are you still having hot water issues?

To your direct question, where is the water heater check valve? On the newer campers there is one screwed into the top discharge port. It is part of the winterizing bypass kit. It comes into play when you bypass the tank when pumping food grade antifreeze in the system it prevents antifreeze from back flowing into the heater.

See theses 2 pics. This is off a 2004 Sunline. Do not know if this if close to your model year.

Here is an angle view. The top tank fitting has a hex on it, that is the check valve.

Sometimes that check valve will fly apart inside or the plunger get stuck from mineral build up in the water. Either condition can restrict flow. The check valve is a plastic plunger with an O ring, a spring and a little plastic clip to hold the plunger from coming out.

As Tommie stated make sure the lower bypass valve is in the correct position and not bypassing the heater. We do not know if this was working all along and then stopped or this is the 1st time you ever used the camper and cannot get it to work.

Hope this helps

John

I have a 2001 T-2370 and the hot water tank has 2 valves. If both are turned toward the tank, you have hot water. If both are turned toward the lines then you will be bypassing the H2O tank. It doesn't have a check-valve (at least I don't think it does).
