no water after water heater

I have a forest river Vibe. Had it winterized and now I have turned both bypass valves at the water heater and can't get any water. I only have 2 valves at the heater . What am I doing wrong?

Have a picture of the orientation of your valves? My bet is your inlet valve is turned off.

May have figured it out. I have the cold water valve toward heater and the hot 1/2 way between heater and bypass line. Seems to be the only way to get water. But I don’t understand why valve would be 1/2 way.

Some/all 2-valve systems have a 3-way valve.

Do you know what the purpose is of the three-way valve? And why would I only need to split the hot water valve?

This, it saves a valve.

My bypass consists of three two way valves.

Have you run the water long enough to fill the water heater? It takes a long time to get 6 gallons in there. Put the valve in the proper position first, so it points at the water heater, not the bypass line.

And make sure the anode rod/plug is installed. (You may have a huge puddle outside the trailer.

Write back and tell us what you found.

I have had many trailers that had a standard bypass setup. This one will not work if they are pointed at water heater.the only way it will fill is with the cold valve toward heater and with the hot valve 1/2 way .but now it will fill up.

To fill the WH faster open the pressure relief valve.

Or just open all the hot water faucets. Pumps only deliver 2.5-3 GPM so it's going to take around 3 minutes to fill the tank if on a pump. Maybe a little less if hooked to city water.

Relief valves are not designed to be used this way. Often leads to a leaking relief valve down the road.

To help you understand the function of a 3-way valve look at the attached picture. You have one at the cold inlet to the WH and one at the hot outlet from the WH. The 3-ways in your rv is a T-Port 90 degree (Flow Plan #3) set to for position 2 (pass-thru) when in normal flow. When winterized both valves are set to position #1 diverting the antifreeze from the cold water inlet pipe through the bypass pipe to the hot water outlet pipe going to the rest of the plumbing.
