Use on Many Outdated Valves

Many Valve Changers work in many situations, offering stoppers to fit undersized ports, stop units from 16 inches to 6 feet long. O-Ring style stoppers for extra small openings. Rectangular and cylindrical rubber stoppers.

Save Money

Remove only the leaking fitting. No excavation at the main or squeezing off the service line to shut it down.

Use on Standard Valves

Works on the valves you actually encounter. Other tools require specific minimum port dimensions and are limited to schedule 40/80 steel pipe. In the real world, that rules out a lot of jobs.

Service Head Adapters

Decades of installing different service head adapters and anodeless risers make it difficult to use a standard tool. Specialty stoppers are required to get the job done. 

Undersized Ports
