No Water Comes Out Of The Hot Side Of My RV's Faucets.

RV water pump will pump cold water, But not the hot, city water will work, But not thru the Hot Faucets.

ANSWER: Hi John thanks for submitting your question on our Ask An RV Question Page.

If I understand you correctly you are not getting any water cold or hot through the hot side of your RV's water faucets.

Based on your description the first thing I would look at is to see if your RV's Water Heater has been bypassed as part of the winterization process. This could be the cause of the problems you describe.

There are two ways of bypassing a water heater on an RV. The first way is using the RV's built in Water Heater Bypass Valve (if your RV is equipped with one). You need to go to your RV's exterior Service Compartment also known as your RV's Water Compartment.

In that compartment you will see some valves or levers and they should be marked. Some might say Tank Fill/City Water. You are looking for a valve or lever marked Water Heater Bypass. If you find that valve take it off the water heater bypass position and that should solve your problem.

If you do not find a valve then there is a good chance that your RV may have been retrofitted with an after-market RV Water Heater Bypass Kit which is usually located on the rear of the water heater water inlets and/or outlets. So you will need to take a closer look at the rear of the water heater to see if you can see a valve. The location of the valve varies by the type bypass system they used.

The only other things that could be causing this problem is a clogged or leaking hose leading to or from the water heater or the water heater itself is leaking.

I hope this helps.
