little or no hot water flow

NO flow of HOT water thru hot side of faucets/shower.......check valve on water heater outlet stuck closed/jammed/clogged. ALL hot water comes thru it>


Luke warm/cool water flowing out of hot side of faucets/shower....then water heater bypass valve is open or leaking thru enough that cold water is going into hot water line making it luke warm/cool (check valve on hot out closes/reduces flow due to cold water flowing into hot line)

No hot water flow thru just one fixture......local problem with that fixture

Moved from Forum Technical Support

the only valve i could find on the water heater was on the cold water inlet and was told by a R.V.parts man that it was a back flow preventer which i replaced i looked but could not find any kind of valve on the hot side of the water heater

YOU didn't answer any of the questions

NO flow on hot side of faucets/shower......check valve on hot out bad

Flow but it is luke/warm ......bypass leaking thru from cold inlet to hot out (or outside shower not turned off using cold/hot knobs)

No flow but only at one faucet....bad faucet



Do you have a line that connects cold inlet to hot outlet?


Some use just 1 valve. It is a combo cold inlet and bypass
Turn one way water flows into water heater thru bottom line
!/4 turn and water bypasses water heater


This one is in bypass....valve handle perpendicular to cold inlet (parallel to bypass line). No valve in Hot out (top line) as it uses a check valve in fitting on tank

Do you have a outside shower that the valves could have been left open, that mixes the water.

How about some punctuation. I gave up trying to read your posts.

yes I have a outside shower that is turned off at the faucet and the spray head I'm getting water flow and pressure to the hot water heater the heater is heating the water but I get no hot flow out of water heater, is there a flow check valve on the hot out flow if so where is it located I can not locate it

my coach has a bypass valve which was factory plumbed not a bypass tube set up as is pictured I have owned various RV's that I have installed winterization kits on myself

is there a flow check valve on the hot out flow if so where is it located I can not locate it

If you have one it may be threaded into the hot water tank. Look for a larger than usual fitting on the outlet side.

My no flow problem is solved on the Journey 39K models they put the hot side check valve behind the water service panel in the line that goes from the water heater to the water heater bypass valve and to access the check valve you have to disassemble both pieces of the panel thanks to all of you that responded I appreciate the help
