Product details
The Hayward SP1500UNPAK2C is the genuine set of flush union connectors for Power-Flo pumps. The connectors are 1-1/2 in. socket, so they solvent weld to standard 1-1/2 in. PVC and give the pump a detachable joint at each port.
Fit
They fit the Power-Flo SP1500 series and the Power-Flo II SP1700 and SP1700UN, and they are also used on the Power-Flo Matrix SP1590 series and the Super Spa SP-3500.
Why bother with unions
Once unions are in place, removing the pump is a matter of loosening two nuts. Motor changes, seal work and pulling the pump for winter all happen without cutting or regluing pipe. This pack includes connectors for both ports.
