Hot water tank won't fill

[sphinx]

I replaced my hot water tank and my outside shower taps. The tank filled originally but I wasn't getting any water coming out of the hot taps anywhere in the trailer. I emptied the tank and now it won't fill. I open the hot water taps the pump doesn;t even come on. My valves are all in the corrct direction. What could be the issue?

Thanks

1) you do not have the valves in the correct position.
2) you do not have the HW heater plumbed correctly.
3)you have no water in the potable water tank.
4) you do not have the water pump turned on.
Connect the city water to it and see what happens.

Could also be a clog in the supply line to the WH. I assume the cold water works OK?

Turn off the water supply and pump. Disconnect the supply to the water heater, and then turn on the pump with the hose in a bucket. If no water comes through then it's clogged or a valve is closed.

I've had a clogged supply line before (between FW tank and the pump) and I thought it was a pump issue. A new pump proved me wrong.

Have you opened the pressure relief valve on hw heater to allow water to enter tank and air escape?

"Have you opened the pressure relief valve on hw heater to allow water to enter tank and air escape?"

Opening the hot water taps does the same thing.
As for the tank not filling, that has got to be something very simple. Have you tried it on shore water, or just the camper supply?

5) you have a stuck or clogged check valve near the water heater.

How many water heater winterize valves do you have?
IF you have 3 valves, you probably don't have a check valve.
If you have only 1 or 2 valves you most likely do have a check valve.

We had a poster here recently who found a broken check valve and
he was also getting no hot water.
