replaced pressure tank still no water?


Having no water we replaces the old pressure tank. Still no water. The well pump seems to be running and isnt filling the tank. There is 40 # in the new tank. Could the well pump need replacing? Or ???????

40# of what? How are you coming up with this number?
Is it a submersable pump or is the pump close to the tank?
Does the new tank have a place to connect an air hose?

A bad pressure tank would have 0 to do with not having water being pumped into the tank.

Unless of course said pressure tank is not connected to the water system.






More info is needed? Submersible pump? Jet pump? What type of well? Depth of well? Distance of pipe from pump to pressure tank.

Let's start there.

(For you musicians, the # is also called the pound sign although to be absolutely correct I should say #"^2 for pounds per inch squared, or PSI, as opposed to just pounds)

Your pump system has a turn on pressure (say 25#) and a turn off pressure (say 50#). TUrn off the pump and open a cold faucet until the water stops flowing. Then adjust the pressure tank to be about 2 to 3# less than the turn on pressure as measured using a portable gauge and portable air pump at the pressure tank top valve. Close the faucet and turn the well pump back on.

For your new pressure tank with bladder, the tank pressure (measured at the top valve) will not drop below the pressure you set the tank at (40#? 25#?). When the system pressure is at or above the pressure tank set pressure or starting pressure, the pressures will be the same.

The pressure should build up to the turn off pressure (as seen on the system gauge) and the well pump should then shut off.

If the system pressure does not build up then you may have a major leak somewhere or a problem with your well pump. Usually a household water system should have a maximum (well pump turn off) pressure of around 50#.

When the pressure tank starting pressure is approximately equal to the well pump turn on pressure and the tank has no water in it to start with, the fraction of the tank volume still occupied by air when the pump turns off is approximately the turn on pressure divided by the turn off pressure. (You can't see or measure this.)

If the pump is running and no water is coming out then one of two problems exist.
The pump is no good and not pumping.
The pipe between the pump and the tank is broken and water is flow somewhere else.

Iam guessing the 40 # is on the bladder inside tank....if pump is running ..you may need to prime ....again as mentioned ...is it a submersible..or deep well jet pump...

Your right I forgot about that. No water in the well would certainly be a third option.
