It sounds like you have crossover problem, so dealer is saying to install check valve on the cold water line.

I have cold water coming out of my faucets but no water at all coming out of the hot side. I have an atwater.


Have you checked your by-pass valve(s) at back of water heater for proper positioning? Cold water comes in bottom fitting at back of tank, and hot comes out the top fitting. Make sure any valve at those 2 spots are open and anything in between is closed.

Turned off the hot water to fix a leaking tap. now the tap has no hot or cold water and the hot water tank valve is leaking?


It sounds like two problems.
Problem 1) Clog inside faucet or clog inside pipes at faucet
Remove supply tubes leading to faucet and see if problem is inside pipes or inside faucet.
My bet is clog inside faucet.

If you have galvanized pipe that meets copper pipe, this can be trouble spot.

Problem 2) Water heater leak ... you say tank valve is leaking? Is that cold-water shut-off valve? Or tank drain valve? Or TP valve?

If cold water shut-off is leaking, then replace shut off.

If tank drain valve is leaking, then check if plastic valve is cracked. If drain valve is cracked, then replace with a brass valve from Home Depot. If plastic valve breaks off, then use hammer and screwdriver to gently chip out the broken plastic valve. New valve threads need teflon tape to seal pipe. If valve is just dripping, then put garden-hose cap over end of valve and screw down tight.

If TP valve is leaking, then replace with same temperature and pressure rating.
New TP valve threads need teflon tape to seal pipe.

Problem 3) If pressure is low all over house:
Buy pressure gauge at hardware store that screws onto hose connection.

Test pressure on outdoor spigot.
Open faucet and check if pressure drops. This says if problem is inside pipes that enter house.

Test pressure on water heater drain valve.
This says if pressure problem is before -or- after water heater.

If problem is before the water heater, then shut-off valve located on cold water line is suspect.
If problem is after water heater, it could be in hot water outflow pipe on top of water heater, or a nearby elbow.

Remove hot water line leading from water heater and check pressure. This says if problem is where hot water leaves tank.
Read articles above about clogs inside water lines.

My suburan hot water in my 5th wheel camper only makes warm water, never hot. what is the problem?


First, let water heater heat up until it shuts itself off. Now carefully, ( it should be hot) open pressure relief valve slightly and catch some hot water in a cup or container. Compare it to what comes out your tap, that you say is warm only. If that water from pressure relief feels hotter, then check your by-pass valves for proper operation and position on rear of water heater, as it may be in a position that is allowing cold to mix with hot, creating warm. Cold line will go direct in the bottom fitting and hot will come out top fitting, and make sure any valves in between those 2 lines are in off position. If all is well there, or water from pressure relief is only warm as tap as well, then buy a new thermostat and ECO for that particular model water heater from RV dealer/service center, and replace them. They are behind rubber cover on upper left side on water heater. When cover is off, they are held against tank by 3/8 nut. When you replace it, snug nut up good but be careful not to go too much and snap that small brass stud that nut goes on. Pay attention to position of old one, so new one goes same way.

Have a 2005 coach w/Atwood DSI-RV 6 gal water heater. Gas lights, heater fires and gets hot, but doesn't transfer the hot water through the lines to the sink faucets. jwmystery@aol.com


You need to check by-pass valve(s) on back of tank for proper position. You need cold open going in to bottom tank fitting, and hot open at top. If any valves in between those 2 lines via "T"'s, turn them to off position.

2010 view winn- the hot water faucets, when wide open the flow is very slow-light flow. The hot water heater has never been used. I have filled it and drain it, there was no trash in it. I refilled it and...


Double check that washers inside fittings attached to back of tank, are not wedged or pinched in there restricting flow. Drain tank, relieve water pressure prior, obviously. The other thing is to check that the by-pass is allowing good flow in to tank when in normal operation mode. Have seen those only go half way inside valve, but lever is at wide open setting. If all that checks out, try removing the check valve on tank, and replace it with a 1/2" galvanized pipe nipple, ( or certified plastic/nylon fitting same size) and reconnect water line direct to that, without a check valve. That should do it if nothing else was wrong. Now you have a choice, either change it or leave it out if everything seems ok, but double check that hot water isn't siphoning back to another utility such as toilet if you leave it out and toilet is close. Feeling that cold line (inlet) when water is hot should tell you. I've seen the check valve in both locations, hot (at top of tank) and cold (at bottom of tank -inlet) Not 100% sure why, right from factory that way, but I say, put it on bottom fitting if required at all. Let me know how you make out.

Cold water runs through the faucet shower but no water at all through hot water side


If no hot water at any faucet, and your sure water in water heater is hot, check by-pass at back of tank for wrong positioning.

Hot water heater is not working correctly on electric


Check that the by-pass valve(s) on or near back of water heater are in the proper position. If your stumped on how they should be for normal operation, remember this. Cold water has to flow into bottom of tank, so that valve needs to be open straight into that fitting. Then the hot comes out the top, so that valve has to be open as well. Any valves in between those lines need to be closed, otherwise it will mix cold and hot . If still not sure, get back to me, with location of any valves there, and I'll guide you through it.

RV water heater problem: my water heater ignities, when I turn on the hot water faucet there is a steady flow of water but no hot water. The bypass valve is parallel with the cold water line. I can only...


The first question is this
From the outside of your RV is the water heater square or is it longer than it is tall?

If it is square it is a Suburban
If it is longer than it is tall then it is an Atwood
Forest River mostly uses Suburban

How long do you let the unit burn/run before you try the hot water? From a cold start it will take - depending on the outdoor temp. & the gallon size of your water heater, 15 to 30 minutes for the water to get hot.

If you have waited this long then I would suspect the bypass valve is in the wrong position
