Quick Tips
- Turn off the pool pump and release filter pressure before removing the old union.
- Clean the threads on the valve body thoroughly to ensure a smooth, debris-free fit.

PRO TIP
Always inspect your O-rings when replacing a union. If the rubber is flattened or cracked, replacing the O-ring at the same time as the union will prevent follow-up leaks and frustration.
Always follow label directions and safety guidance. Keep pool chemicals and accessories stored safely and out of reach of children.
