Product details
The Waterway 400-5570 is a complete pump union assembly. One end is a 2" union nut that threads onto a 2" pump port, and the other end is a 2" slip socket that glues to 2" PVC pipe.
Why the union matters
The union is the joint that makes a pump serviceable. With one on each side, a pump can be unthreaded and lifted out for a seal change, a motor swap or a winter teardown, and go back in the same afternoon. Without them, every one of those jobs starts with a saw and ends with new couplings and a wait for glue to cure.
If your pipe is 1-1/2"
Plenty of installations run 1-1/2" PVC into a pump with 2" ports. A 2" to 1-1/2" reducer bushing sits in the slip socket and lets you glue to the smaller pipe. It is a separate item, so add it to the order if that is what you have in the ground.
