Pentair .75" NPT Spigot Sand Filter Drain

The Pentair .75" NPT Spigot Sand Filter Drain (part number 152165) is a specialized external plumbing component engineered for a wide array of Pentair top-mount and side-mount sand filtration systems, including the Sand Dollar, Tagelus, and Cristal-Flo series. Injection-molded from a heavy-duty, high-impact polymer composite, this drainage assembly features a standard 3/4-inch Male National Pipe Thread (MNPT) connection on one end and a smooth spigot outlet on the other. Its primary functional role is to provide a secure, easily accessible port at the absolute base of the filter tank, allowing pool owners and service technicians to smoothly evacuate water from the pressure vessel during routine maintenance, winterization, or media changes. When threaded into the lower tank wall with its accompanying gasket, it forms an absolute watertight seal that safely contains continuous system operating pressures up to 50 PSI without weeping or leaking. Built to endure constant outdoor exposure, UV weathering, and prolonged contact with harsh pool sanitizers like chlorine, bromine, and seasonal acid washes, this durable drain plug prevents catastrophic pressure loss. Due to its compact, lightweight plastic architecture, the individual spigot drain component carries a minimal product and shipping weight of approximately 0.08 pounds (about 1.28 ounces).
