Hello all

[georgeguenther]

I just bought a used camper that's in excellent condition, I just have one problem...the water heater. The tank gets hot and every now and then you get a burst of hot water. The guy I bought it from said he had a problem with the check valve on the top. I replaced the check valve today and it's still just giving me a burst of hot water when I turn it on the goes back to cold. Any help would be greatly appreciated! Thank you.

OTOH It's not a hard part to switch out, this grandma has put in a new water heater.

Are you sure the outside shower (or inside) doesn't have the valves open but the showerhead closed? That is a frequent issue that "short circuits" the hot water.

Perhaps the bypass valve is open. Different builders use different valves but this pic may help. Assure the center valve is closed
