- Install the new tailpieces onto the plumbing and seat the provided O-rings properly.
- Thread the union lock-nuts onto the pump and tighten by hand until snug—do not overtighten.
- Restart the system and check for any leaks at the union connection points.
Troubleshooting
-
Leak at union: Confirm O-ring is seated flat, sealing surfaces are clean, and lock-nut is tightened evenly.
-
Union misalignment: Ensure plumbing is properly supported and tailpieces are aligned before tightening.
-
Flow issues after installation: Check for obstructions or misalignment inside the plumbing or pump connections.
Maintenance Tip
Inspect union O-rings annually and replace if flattened, cracked or brittle. Replacing tired unions with the SPX2700UNKIT helps prevent leaks and makes ongoing pump maintenance much easier.
