PumpMan NorCal provides certified backflow testing to protect water systems and ensure compliance with California regulations.
Tanks, whether air-over-water or pre-charged bladder style, are used to maintain system pressure and minimize the frequency of pump starts. Tanks of various sizes have drawdown capabilities depending on pressure switch settings. Tanks should be selected to provide a minimum of one gallon draw down for each gallon per minute of pump capacity. Large capacity systems may require multiple tanks. Constant pressure type systems require much smaller pressure tanks.
