 PRO-SOURCE Pressure Tanks have been discontinued. Check oir Mailine Tanks

The Pro-Source Series pressure tank made by STA-RITE Industries are one of the most high quality well water pressure tank available. These pressure tanks have a new tested-tough composite base. This new composite base offers superior corrosion resistance over conventional steel base configures pressure tanks. This base will never rust! The heavy-duty 'tested-tough' composite bases are made of high impact material for drop, dent and scratch resistance. The 16" and 20" tank base is made of Hi-impact Polypropylene and the 24" tank base is made of Hi-Impact ABS. The new composite base is also equipped with mounting holes for installations that requires anchoring the tank.

How to Choose your Steel Pressurized Water System Tank

Pro Source Tank Sizing Rule: Size tank for one gallon of draw down for each gallon per minutes of pump capacity.

Example: For a 1 HP 20 GPM unit pumping 25 gallons per minute on a 30-50 pressure switch setting, the properly sized Pro-Source tank is a SR85-T52 which has a 26 gallon draw down.
