400-9230 vs. 400-4061 Pump Union
Waterway 400-9230
- 2" pump union nut / female buttress thread
- 1-1/2" slip connection
- 2" spigot connection
- O-ring included
Waterway 400-4061
- 1-1/2" pump-side buttress-thread connection
- 1-1/2" slip plumbing connection
- Smaller pump-side union than the 400-9230
If a Waterway 400-4061 is too small to fit the pump's threaded connection, the 400-9230 may be the appropriate larger union when the pump has the required 2" male buttress threads. Always confirm the pump connection before installation.
Installation & Compatibility FAQs
What size pump connection does the Waterway 400-9230 fit?
The 400-9230 is designed for a compatible 2-inch male buttress-thread pump connection. The union nut threads onto the pump while the included O-ring creates the seal at the union face.
Is the Waterway 400-9230 a 1-1/2" or 2" fitting?
It incorporates both sizes in different parts of the fitting. The pump-side union is a 2" connection, while the combination tailpiece provides a 1-1/2" slip socket and 2" spigot.
What does 1-1/2" slip / 2" spigot mean?
The inside of the tailpiece is sized to accept compatible 1-1/2" PVC pipe as a slip connection. The outside of the tailpiece functions as a 2" spigot, allowing it to fit into an appropriate 2" socket-style fitting.
Does the Waterway 400-9230 include an O-ring?
Yes. Waterway identifies the 400-9230 as a complete union assembly consisting of the union nut, combination tailpiece and O-ring.
Is 400-9230 the same as Waterway 400-4061?
No. The 400-4061 uses a smaller 1-1/2" pump-side union connection. The 400-9230 uses the larger 2" pump-side union and a combination 1-1/2" slip / 2" spigot tailpiece. They should not be treated as interchangeable without checking the pump connection.
How do I know if 400-9230 will fit my pump?
Verify the pump manufacturer and model number whenever possible and confirm that the pump uses a 2" male buttress-thread union connection. Measuring only the PVC pipe size is not enough to determine pump-union compatibility.
Need Help Confirming Fitment?
Pump unions that look nearly identical can use different thread diameters and plumbing connections. If you are replacing an existing union and are unsure whether Waterway 400-9230 is correct, send Aqua Terra Backyard your pump manufacturer, model number, and clear photos of the threaded pump connection and existing plumbing. Our team can help verify the correct fitting before installation.
