what causes low pressure on a pump for well water
Why Would You Lose Pressure to a Well? As the water level in the tank drops from household demand, pressure in the tank declines to a preset minimum. The well pump then actuates to pump more water into the tank and restore pressure. An under-inflated air bladder results in lower water pressure output from the tank. Well-pressure tanks provide an automotive-style Schrader air valve on the top or the side where bladder pressure can be verified with a standard air gauge.
