Question about well pressure tank
Not all well tanks have the bladder type tanks, some have no bladder within them at all. Try this: Turn off the power to the pump, drain ALL the water from the tank you can. Next make sure all faucets, drain valves, and fittings on the tank are closed. Turn the power back on and listen to make sure the pump is running, and hopefully you will hear water coming inside the tank. Let the water continue to fill the tank until the pump shuts itself off. Check to see how much water pressure there is in the tank and record this somewhere for future reference. Turn on a faucet, wide open, which is furtherest from the tank and allow to run until the pump kicks in again. Note the pressure at which the pump starts to run again and record. Close the faucet and allow the pump to fill the tank until it cuts off again. Compare the "cut-out" pressure, when the pump shuts off automatically, with the first reading you had. This should be very close. Tanks without bladders need to be drained and re-filled in order to re-pressurize the tank if the system is not used very often. These tanks depend on entrapped air to build up pressure.
