After checking my water tank for water coming out of the air valve I discovered none, however noticed that there is an in-line pressure gauge that reads ZERO. This is without any water running i nthe house and may be the way it should read unless water is running. My common sense tells me that there should always be pressure in the line regardless of the tanks bladder being busted. Maybe not if the pump is not running. Could the electrical box thing installed close by the pressure tank be bad and not telling the tank what to do. Not sure what it purpose really. I call it a regulator. It is a small 4"x4"x4" plastic box. It was alte at night and I forgot to take my air pressure gauge with me when checking the tank so I don't know how much pressure was really in it other than air was coming out when I pushed the pin in on the air stem of the tank. Thanks.
