No Hot Water

[Redneckrebel]

Looking for help...we have a 2009 wildcat 5th wheel....we have no hot water out of faucets. There is hot water in tank and if bypass is open cold water comes out. Any ideas or suggestions?

There are likely three valves for your water heater -- one on the pipe for cold water entering the tank, one on the pipe for heated water leaving the tank, and one on a crossover or bypass pipe connecting the entry and exit pipes.

In normal use the valves on the entry and exit pipes should be open. The valve on the crossover pipe should be closed to prevent cold water from crossing over and mixing with the hot water. For winterizing, all three valves should be reversed from those positions.

There is only 2 valves on mine. 1 on the cold water fill line and 1 on the crossover which i assume to be the bypass

As Bob said above, you probably still have the crossover valve wrong.

Please read this thread and let us know if it helps:

If i shut the crossover valve i get no water from hot side. With crossover open i get cold water from hot side

Then it sounds like you have the very top hot water outlet valve turned wrong.

Please post us a pic of the valves and we will get you straight.

Does your valve setup look similar to this:

Similar but not exactly. There is no valve on the hot water outlet

Can you please take a pic with your phone and post it..... of the back of the water heater.

I sent you a PM with a phone number if you want to text me the pic if you are unsure how to upooad pics here.

If there is no valve on the hot outlet, you would have a check valve that is stuck.

Edit: if there is a check valve, open kitchen faucet (hot) and tap on valve with a wooden spoon, lightly if plastic.

Here are the pics of the OP's lines.

It does appear they are going to have a one way check valve in the hot water outlet.

Thank you wmtire. So i guess my next question is how to fix the issue. Sorry for all the questions i just graduated from a tent to this camper

The cross over valve needs to be closed. It it is when you say you get no water out. Then the other valve in the blue line putting cold water into the heater need to be open. This should allow water to enter the heater. It will not exit the heater until it fills with water. Did you wait long enough for it to fill? Open the pressure relief until water spurts out of it.

If the valves are in the proper position and water is coming out of the pressure relief valve but not out the hot water line you probably have a stuck check valve on the hot water exit line. Try the remedy for it described previously.

[Redneckrebel]

Would the check valve be where the hot lines comes out of the tank (brass and black part in pics)?

[wmtire]

You have the valves turned correct in this pic for normal usage:



As stated, go outside and briefly flip up lever on the temperature and pressure (aka T&P) relief valve on the face of the water heater (pic below). If water comes out here, then then tank is full and pressurized. Be careful in case the water is hot so you don't get it on you.

Yes, but just the brass part. You don't want to be tapping on the plastic fitting.

[Redneckrebel]

Ive done the pressure relief so i know its full and hot. I will try tapping on the brass fitting with hot turned on

If that doesn't work, you can turn off the water supply and water heater to the RV, relieve the pressure from the cold and hot water lines by opening up taps, then actually unscrew the water line from the hot water outlet check valve. You can then look at or remove/unscrew the check valve from the tank to see if it is corroded/stuck.

Capacitor provided you a link to one of these in post #9 above.

Did you find a solution?

[Redneckrebel]

I will be there tomorrow afternoon after work ill let you know then

liike menntioned check valve on hot out 1/2" easy replacement or check your outside shower if you have one and make sure both faucet knobs are off .
