How to use

Install the siphon directly to the fixture outlet sized for 1.5", ensuring that mating surfaces are clean and properly aligned. Secure connections according to local plumbing practice, using compatible fittings or seals. After installation, run water to verify correct flow through the trap and check all joints for leaks. Periodic inspection and cleaning of the trap area will maintain drainage performance and prevent buildup.

Usage recommendations

Use appropriate sealing materials and hand-tighten fittings before final torque to avoid overtightening. When replacing an existing siphon, confirm that the outlet height and alignment match the 1.5" connection to ensure proper installation and trap function.
