Less water volume on the hot side?

[Auggie56]

From all four water valves.

How about a little more info/details?????


What brand/model is water heater
What do you mean by 'all four water valves'????-------Faucets?


From the little you posted it sounds like the 'check valve' in the HOT outlet of water heater tank is clogging/failing and restricting the flow of Hot water when using a faucet/shower

I'm not sure how that check valve works so maybe that's the problem?



Thanks

Typically, there is a check valve, or one-way valve at the water heater outlet port. That allows hot water to exit the heater, but no water can enter the heater from that same port. If that valve sticks, it restricts the water flow out of the heater, resulting in what is happening to you. Low water flow from all hot water faucets. Some RVs have two manual valves to by-pass the water heater for winterizing. A check valve eliminates the need for a second manual valve to isolate the water heater.

Repair is easy. Either remove the valve and forget about it, or replace it with a new valve, preferably brass. If you winterize, you will need the check valve, however, to prevent filling the heater tank with antifreeze.

My valve in towards the front and is plastic. It would be simple to just replace it as the stove needs to be removed to access it. Many thanks for the picture.

My valve is 3/4 all the specific camper ones I find are 1/2. Is this valve the same as a camper valve? I'd say yes but I don't know enough about the system just to put anything on it.

This is a wild shot, have you checked to outside shower? If by chance those valves (both hot and cold water) are not completely closed, you can have a reduced volume throughout the rest of the MH. Worth a shot.

Let us know what your fix ends up being.

My bet is there is a winterizing valve that is not shut/open the whole way. A partially open valve will restrict water flow.
