Waterway Pump Union Assembly, 1.5" x 1.25" Hose Adapter In stock$1299
Quick overview
- Union, not glue A union lets the pump come off for service without a saw and a pile of couplings.
- Hose adapter included Supplied with the hose adapter rather than as a bare nut.
- O-ring included The sealing o-ring comes with the assembly, which is what actually makes the joint tight.
- Waterway 400-9280 Ordered by part number so the thread and the adapter match.
- Check your sizes The listing carries both a 1.5" x 1.25" hose adapter description and a 2-1/2" union nut description, so measure before ordering.
- Common service part Union o-rings and nuts are among the first things to leak on a spa or pool pump.

Product details
The Waterway 400-9280 is a pump union assembly supplied with a hose adapter and an o-ring. It is the fitting that lets a pump be taken off without cutting into the plumbing.
Why unions earn their place
A pump gets pulled more often than anything else at the equipment pad: seals, impellers, motors, replacements. If it is glued in, every one of those jobs starts with a saw and ends with new couplings and a wait for the cement to set. A union unscrews by hand and the pump lifts straight out.
Sizing, read this first
The source information for this part is not consistent. The product title describes it as a 1.5 inch by 1.25 inch hose adapter, the longer description calls it a 2-1/2 inch union nut with a 1-1/2 inch or 1-1/4 inch hose adapter and an o-ring, and the size attribute reads 1-1/4 inch. Measure the union you are replacing, or tell us the pump model, before you order.
The o-ring
It is included. It is also the part that usually fails first, so if a union is weeping rather than cracked, start there before replacing the whole assembly.
