Pool Expansion Plug 2 Inch LeakResistant Rubber Skimmer Plug for Pool Line Testing

Rubber Expansion Plug for Pool Lines and Skimmers A durable rubber plug designed to seal and test pool plumbing and skimmer openings with a maximum expansion capacity of 2 inch. Provides a reliable, removable seal for maintenance, leak detection, and temporary line closures. Key benefits Effective sealing: Expands up to 2 inch to create a tight, leakresistant seal for lines, skimmer ports, and other pool plumbing openings. Simple to use: Quick installation and removal reduce downtime during maintenance and testing tasks. Reusable and durable: Molded rubber construction resists wear from repeated use and exposure to pool chemicals when rinsed and stored properly. Versatile application: Works with a variety of pool plumbing and skimmer configurations for temporary shutoff and pressure testing. Features and specifications Material: Solid rubber construction for flexibility and durability. Expansion capacity: Up to 2 inch maximum expansion to fit a range of opening sizes. Function: Expansion plug design creates radial compression against pipe walls or skimmer surfaces to block flow and hold test pressure. Compatibility: Intended for use with pool lines, skimmer ports, and similar plumbing openings; suitable for most standard pool maintenance tasks. How it solves common problems Stops water flow during or replacement of returns and fittings, preventing water loss and simplifying work. Allows controlled pressure testing of lines to find leaks without removing large sections of plumbing. Seals skimmer openings for drain or deck work without needing permanent fittings. Typical use scenarios Pressure testing a pool line after replacing a section of pipe: insert the plug into the open , expand to seal, and pressurize the line to check for leaks. Sealing a skimmer mouth during deck repairs or when replacing a skimmer basket: use the plug to prevent debris and water ingress. Temporarily blocking a vacuum or waste line during pool maintenance to redirect flow or isolate a section of plumbing. Installation tips Inspect the plug and the opening for debris before installation. Insert the plug into the opening and expand gradually until a secure seal is formed. Do not overtorque expansion mechanism; confirm the seal visually and with a lowpressure test before full use. Rinse and dry the plug after exposure to pool chemicals and store in a cool, dry place. What to expect A practical, easytouse rubber expansion plug that simplifies pool plumbing maintenance and testing by providing a reliable temporary seal with up to 2 inch expansion capacity.
