Question about Heating & Cooling
I can't find that model number on the Amtrol site, please check it.
Is this a water storage tank? With an air charge?
Remove the dust cap on the charging valve on top, Schrader valve, like a car tire.
Use a small tool to slightly depress the pin in the middle.
If water comes out, the tank should be replaced but adding air will help for a while.
If air comes out, you can pressurize.
Determine the pump turn on and turn off pressures using a good pressure gauge.
Turn on may be 30 psi, turn off should be around 50 psi, TYPICALLY.
Switch the pump off.
Open a valve and drain all pressure from the water system.
Get a tire pump and pump up the tank pressure through the top valve to 2 psi lower than the pressure that the pump turned on above. If the pump turned on at 30 psi, pump up to 28 psi.
Put system back in service.
