Water Pressure Loss

Originally Published in MotorHome Magazine

We are having a perplexing problem with our hot water tank. The pump is working properly, but we will lose pressure suddenly. We can restore pressure by opening and closing the cutoff on the front of the hot water tank. This does not completely solve the problem, since we have to do it over again, when using the water later.

It may be a faulty check valve at the water heater. Are there any external leaks or dripping faucets, etc.? Is this problem only with the pump? Is it fine on city water? You’ll have to do a little checking before you can solve this one.
