???? about well tank water level and air pressure

I have noticed that the well pumps kicks on and runs anytime there is water used in the house (under renovation and not being lived in yet). The water pressure will go from 60psi to 30 or 40 cant remember and triggers the pump to kick on, the needle literally just bounces from 60 down to 30 and back up to 60 continuously when water is on somewhere in the house.........I think that tank (looks like a 80-120 gallon (WAG) galvanized steel tank) is not holding any water and it when tapped its sounds hollow.

My thoughts are: there is to much air in there and that is not allowing the water to refill the tank, so the well pump runs anytime there is water used (toilet flushed)

The tank has a plug on the top that looks 1-2 inches and I was wondering if I opened that and then try to use some water if the tank would fill back up

any ideas

Sounds like no air.

You need to turn off the pump
Open a faucet tp relieve pressure
Test with a tire gauge.
Should be 3 or so PSI below cut in pressure.

If it had too much air the bladder would collapse before kick in pressure and you would have a no water issue for a moment until the pump built pressure back up.

galvanized bladderless tank. "air over water".

however, it does sound like no air. I think the tank is completely full of water.. u can't compress water so it's shortcycling. kill the power and drain tank completely.. then close the drain, turn on the power, and let it build to cutoff.. should be much better. asap too, shortcycling is #1 killer of pump motors.

Ideally you should pre-charge with air to, as lawrosa says around 37 lbs, assuming it's a 40 lb cut-in pressure.

I will try that sunday, I have a fishing tournament tommorrow and have to get the boat ready

I tried draining the tank before and it seemed like hardly any water would come out, which is where my "all air" theory came from...........if it is full of water, could a vacum effect be being created and keeping the water from draining? and removing the top plug would solve that?

thanks for the help so far though

Is the a schrader valve on the tank? Drain the tank and add air. When you drain the tank open a faucet.
