Pressure Water System Trouble-shooting

[Acadia426]

I'm off to a late spring launch and am working to recommission the pressure water system. I filled the 2 water tanks, flushed out the "pink" and turned on the water pump breaker switch. All went well.

But, I then reconnected the Force 10 hot water heater (which I had taken off line for the winter). I made sure I connected the water/in and water/out lines to the proper connections. I then opened the "pressure relief valve" on the heater and bled it.

Now, once the heater is online, no water flows, not hot nor cold, from the faucets, shower, etc...

I've run out of trouble-shooting ideas given my level of skill. I'd appreciate suggestions for any next steps to take.

Any way to turn off/eliminate the hot water heater from the system to see if it works again/similar to the re-commissioning of the water heater?


Is your pump turning on when you open a faucet? Blown fuse/breaker?


A schematic of your system would be helpful.

Since you have bleed via the PSV from the heater, that indicates you had water pressure at that time from the pump. Then your statement neither "hot or cold from the faucets" are you stating no cold water service at all?
If so back to basics,
1) Checking all the valving is on from the water tanks, ( did you turn off when connecting the hot water heater)
2) Is the pump breaker on?
3) Can you hear the pump trying to run when any cold water faucet is open?
If you have no cold water at any area, and your bilge is not full of fresh water, ( ie massive leak from heater connections) then one would have to start from the tank isolation valves and work forward in the system, to find the blockage.
4) So check you have water at the pump inlet, pump outlet
5) Pump runs when outlet disconnected ?
6) Water post accumulator tank ( if you have one)
7) Water at the closest cold faucet to the pump / accumulator outlet
8) Water at the heater inlet,
8) Water at the heater outlet
etc.

All the water heaters I’ve worked on have a check valve on the cold water side. If in reattaching the plumbing the check valve was installed backwards it would stop the flow into the tank and the cold water circuit.

Yes that would be possible, except one would assume that the faucets would have separate H & C hook ups. A backwards check valve would only stop the H side from functioning.


We don't know how the water system is set up and would be nice to have the OP respond here vs. speculation.

Thank you, each and all, for your thoughtful comments. I took them all, and eventually asked a more knowledgeable friend to fix the problem He did. I'll know more, because of you all, the next time.

Don't leave us hanging, what was the problem and fix???
