Question Installing a used well tank

The current well tank we have developed a small leak, so we have turned off all power to the well. We were given a like tank (amtrol) to install, but it is a used one with no directions included.

My husband was running water, with our "city" water line into the tank, thinking it would need water in it to ready it to hook it up to the well pump. He was doing this through the pipe already installed on the tank, at the bottom. Water just comes back out the end, without any going into the tank.

Should we just hook it up to the pipes in the well, thinking that water will go into it, or do we have a clog, as he suggests?

Thanks for any help.

You don't need to fill the tank with water. The pump will fill it.

Before you hook up the tank to the pump and the supply line to your home, check the tank bladder pressure with a tire gauge.
It should be two psi below your pump cut-on pressure. For instance, if your pump has a cut-on/cut-off pressure of 30-50 psi, the tank should read 28 psi without any water pressure on it.
If it has too much pressure for your pump setting, bleed the air pressure off, or if it's too low, air it up with a bicycle pump or portable air tank or compressor, to the 2 psi below cut-on.
To prime the pump after plumbing in the new pressure tank, you will need a gallon jug of drinking water, teflon tape, and an adjustable wrench.
To prime a pump:
1. Remove the 3/4" plug on top of the pump head. Wrap 2-3 flat wraps of teflon tape clockwise only on the threads of the plug as the bottom of the plug faces you.
2. Fill the pump head with water. Plug in the pump and quickly hand-tighten the plug. It will bubble air and water, but that's normal. Keep hand-tightening the plug until the pump picks up the prime, and runs until it cuts off. If it does, finish tightening the plug in with the wrench.
3. If it doesn't pick up the prime, just repeat the process until it does (including new teflon tape on the plug threads).
Good luck!
