Rheem SP23374L Round Poly Drain Valve

Product Description

The RHEEM SP23374L is a round polypropylene drain valve designed for residential and light commercial water heaters. Its primary function is to allow a licensed plumber or qualified technician to drain the tank for routine maintenance, sediment flushing, or unit replacement. Built from polypropylene (PP), the valve resists corrosion and mineral buildup that commonly shortens the service life of metal alternatives. The shank measures 4 inches in length, providing adequate reach through standard tank wall fittings. This is an OEM genuine factory authorized part, ensuring dimensional accuracy and a consistent seal on compatible Rheem and ProTech water heater installations.

This drain valve is suited for residential water heater service work where the existing valve has failed, begun leaking, or become seized from sediment accumulation. Periodic tank flushing is a standard maintenance task on gas and electric storage water heaters, and a functional drain valve is required to complete that procedure. The SP23374L is a direct replacement intended for service technicians and plumbers performing scheduled maintenance or emergency repairs on storage-type water heater tanks.

Installation Notes

Installation and replacement of water heater drain valves should be performed by a licensed plumber. Before removing the existing valve, shut off the cold water supply and power or gas to the unit, and allow the tank to cool to a safe handling temperature. Connect a drain hose rated for hot water to direct flow safely away from the work area before opening the valve. Follow all applicable local plumbing codes during installation.
