Product Details
✓✅ Comprehensive Testing Kit: Unlike basic plugs, this set includes a 4" pipe plug , 21" extension hose, hand pump, 41" safety chain, valve core key, and 2 spare cores. A complete solution for plumbing maintenance without buying extra tools.
✓✅ Secure & Retrievable Design: Features a robust 41-inch safety chain that attaches to the plug's pull-ring. This critical addition prevents the test ball from slipping deep into the sewer line, ensuring easy retrieval after inspections.
✓✅ Deep Pipe Accessibility: Equipped with a 21-inch extension hose, allowing for easy inflation in hard-to-reach areas like floor drains or elbow pipes. The pure copper valve stem ensures a tight seal and corrosion resistance during use.
✓✅ Durable Natural Rubber: Crafted from thickened natural rubber with excellent expansion memory. Specially designed to accommodate various pipe diameters. It provides a reliable seal for water blocking and pressure testing applications.
✓✅ Versatile Application: Ideal for blocking flow in shower drains, toilet tees, outdoor sewage lines, and swimming pool piping. Useful for leak detection and system repairs. Note: Ensure pipe interior is clean before insertion to maintain seal.
