No Hot Water Pressure In My RV - What Do I Do?

by Ed
(Lakeside, Ca.)

Question: I have a 2007 Outback 230RS with a 6 gallon Atwood hot water heater. All of a sudden there is no water pressure on the hot side at all faucets. The cold side works fine and has ample pressure. I drained and flushed out the hot water heater a couple of times with some calcium deposits flushed out. Still no pressure or water flow from the hot side. Heater seems to work fine but no water pressure. The hot water outlet on the rear of the tank seems to be unreachable in the compartment. I'm at a loss. Thank you.

Robbie: I'm sure if you look on the rear of your water heater you will see a check-valve where either the top and/or bottom waterline connections are. Cold water goes in the bottom and hot comes out the top. If you remove the valve (or valves) and find it's full of calcium deposits, I suggest you buy a new check valve from a local RV store. You can remove it completely if you'd like as it only prevents back pressure and replace with a 1/2" by 2" coupler from any hardware store. Using a coupler will also limit the chance of you having to replace it again in the future because of a calcium build up.

Thanks for the Question Good Luck,

trouble shot every possible problem thinking there was an obstruction in one of the lines. Read this forum, and decided by process of elimination, I needed to go here before I ordered a new camper that came with new parts ( lol ). Found the check valve ( plastic part) had broken off one end. Took complete assembly out including the spring, applied new tape to threads, and reinstalled. Pressure is back where it should be if not better. Love the forum, and thanks for all the postings.
