I just got home a few hours ago and after a difficult job of parking in a tight driveway from a small street and leveling; I decided to checkout my new Atwood hot water heater. No pressure on hot, I check the water tank and it shows empty but I do have pressure on the cold side.
I checked all the valves, filled the tank to 1/3 and nothing. Turned the HW tank to bypass, and I have cold water pressure which is normal.
I noticed also the water pump when I first turned it on ran for 30 - 40 seconds, way longer than normal. I do have hot water in the tank when checking the pressure relief valve.
Am I missing a valve somewhere? A bad check valve? If so, where is that and would the new tank install have created this problem? Inlet or outlet from HW tank come loose?
Going to call the shop in the morning that did the install.

Did they replace the check valves on the HW tank inlet and outlet? I have mine removed and no more problems. They degrade and either slow the flow or stop it all together.

The check valve on the inlet really needs to be there. Otherwise, the pressure created by heating the water can cause drips on the cold water circuit (ie: toilet valve).

They didn't charge me for them, so unless they come with the HW tank, I doubt it.

My 2000 Horizon had the same issue. The problem was the output check valve. I replaced the output check valve and two weeks later the input check valve failed.
The technician said he tested, but I doubt he did or didn't test the hot side of the faucet.
The manager did not check either.
It could never have worked for them or me because when the HW heater was installed the outlet line became kinked.
I feel bad for you but I take pleasure in reading this. Lack of quality control like this wouldn't be tolerated where I work. Makes me proud to do what I do.
Hope you get everything in proper working order.
