【New Rubber Formula】 The softer rubber conforms better to the pipe wall and begins to expand when air pressure reaches 35 PSI. Please monitor the rubber plug's condition during use.
【Extra-Long 8.25" Inflation Tube for Easy Access】 Comes with a convenient 8.25-inch inflation tube, allowing you to inflate the plug without bending or struggling in tight spaces like deep drains or hard-to-reach pipes.
【Anti-Loss Chain & Quick-Release Valve】 Includes a 15.7-inch safety chain + large 2.34-inch pull ring to prevent drops. The copper valve core wrench enables fast deflation in seconds.
【Works with Any Standard Bike Pump】 Easily inflate using a common bicycle pump (not included). The plug expands from 1.75" to 2.25", fitting securely in pipes for accurate leak detection.
【Multi-Purpose for All Drain Types】 Ideal for shower drains, bathtubs, floor drains, toilets, pools & underground sewage. 2 plugs included—great for simultaneous testing or backups.
