Installation & Compatibility Notes
Prior to installation, shut off pump power and relieve system pressure. Cut or remove existing plumbing to achieve clean pipe ends. Solvent-cement the slip end according to your plumbing code and thread the MIP end into the matching female port on the equipment body. Ensure the O-ring is lubricated and seated fully before tightening by hand. After installation, restore circulation and inspect for leaks or air intrusion.
Maintenance Tips
- Inspect the union O-ring annually for wear, cracking or flattening—replace if any signs of degradation appear.
- Check the union body and faces when servicing equipment for scratches or gouges that may compromise the seal.
- Keep a replacement O-ring and union body in your parts kit—unions are commonly serviced when pumps, filters or heaters are removed for seasonal maintenance.
