I have a CH HJ 300200 that will not build pressure, there seems to be pressure building in the tank but the Pressure gauge does not move. I removed the pressure line going to the tank, it gets hot and...


Bill:

I would remove the pressure gauge and check the bottom of the air gauge fitting. The small hole at the bottom of the gauge fitting may be clogged. Sometimes when the pressure gauge is installed a piece of Teflon tape (used to seal the threads) can get lodged over the pressure gauge air port.

Honda GVC 160 lost pressure - noticed small black valve (back - rear) after pressure builds up , short spray then nothing - hot water comes shooting out the black valve - did something pop off?


The small black valve is called a thermal relief valve. If it is open you will have no pressure. If the water is getting hot enough to pop that valve, there might be internal problems with the pump.

Pressure will not build up in the tank and the silver tubing gets extremely hot.


There is a moisture release valve under the tank that may have been left open. If so, close it and the pressure will build. The reason the tubing heats up is because it is running so long.

Compressor runs hot and won't build pressure


THE COPPER LINE IS SUPPOSED TO GET HOT, SCALDING HOT ACTUALLY. THE MOST COMMON REASON FOR COMPRESSORS NOT BUILDING PRESSURE IS CLOGGED AIR FILTER OR THE VALVES IN THE HEAD ARE BROKEN OR NOT OPENING AND CLOSING CORRECTLY. YOU MAY POSSIBLY HAVE A BAD AIR LEAK DOWNSTREAM BUT YOU CAN CLOSE THE DISCHARGE VALVE ON THE TANK TO ELIMINATE THAT PROBLEM. HOPE THIS HELPS OR GET YOU STARTED.

Duissamble the faucet after turning off the shutoff vavev and look for an obstruction. The only shutoff if the tempature gets too high is the pressure/tempature pop off valve which would redrirect the discharge down another path. Go to the waterheater and see if it is coming out from another open pipe from the heater.

FF-1800 HAS LOW HOT WATER PRESSURE AND DELAYED TIME TO GET HOT


Sometimes there is a lot of sediment released into the pipes (particularly hot water) when water lines are shut down and restarted as part of a remodel process.

Particularly with a pressure balanced faucet this can create all types of symptoms including those you describe...

Before you go to any expensive lengths, check any intake screens or strainers, both on the faucet and in the other components of the system. A lot of the time this will solve the problem...
