What is the union for?

Hi, The Pump Union is to easily remove and install the pump for repairs and or maintenance work. That way you do not have to cut any pipe, you will unscrew the union.

The PL1643 union will work with the Super Pump and multiport valve as long as they have 1.5" ports. The Hayward Super pumps that are less than 2HP should have 1.5" ports. Hayward multiport valves with numbers like SP710 and SP714 would have 1.5" ports.
