there is a large ammount of air in the water lines. it is on a well and it seems to get worse over night. could the problem be the check valve in the pump. please help if you can
Several things can be the cause. You need to first check your pressure tank to make sure it is set correctly. Check the pressure gauge to make sure it works. If not replace it. Then with a cold water faucet running slowly, check to see what the cut in and cut out settings are. Usually it is 30-50 or 40-60. Once you know the exact cut in setting, turn off the breaker to the pump and open a cold water faucet to release all the pressure. Take a tire gauge and see what the pressure is in the top of your pressure tank. It should be set 2 lbs. below your cut in setting. If 30, then 28, and if 40, then 38lbs. Another issue is whether you have a submersible pump in the well or a jet pump in a pit of the basement. It is possible for there to be aloose fitting that allows air to be sucked in during the pumping phase. Another thing to check is whether you are drawing your well down and breaking suction and introducing air into your system via that means.
