Around 5 or 6 gallons.
CHecked pump tank pressure and it was a bit low (30-50 cutoffs...read about 18-19 psi refilled air to ~26-27 psi). Was wondering how much water should come out of a 20 gallon well pump tank to have pump cycle? Tank seems to hold pressure. Pressure at night is the pressure in the morning when not running water. No short cycling.Toilet flushing doesn't cause pump cycling when at max pressure. Likely obsessing about this. I assume I'm looking for short cycling or drastic drops in pressure if well tank or accessories have gone bad. Thanks in advance.
