Drain Valve Assembly for Water Heaters

This Rheem drain valve assembly fits compatible water heaters and allows tank draining for maintenance or replacement. The plastic valve body connects via standard NPT threads on both inlet and outlet. It is sold new and ready for installation.

Suits direct replacements on matching units

Homeowners or plumbers replacing a factory drain valve on a supported Rheem water heater will find this part matches the original connection sizes. Buyers who need a different inlet or outlet diameter, a metal valve body, or a non-NPT thread type should look at other options.

3-inch overall length and 3/4-inch NPT connections

The assembly measures 3 inches in overall length with 3/4-inch NPT threads on both inlet and outlet. Confirm these dimensions and thread type against the water heater specifications before purchase to ensure proper fit.

Questions about this item

Will the 3/4 in NPT inlet on this drain valve assembly thread directly into the existing 3/4 in NPT port on my older water heater?

Yes, the valve body has a 3/4 in NPT inlet and a 3/4 in NPT outlet, so it matches standard 3/4 in NPT ports found on many existing water heaters.

How can I confirm the SP12159B valve is operating correctly once installed on the tank?

Open the valve handle; water should flow freely through the 3/4 in NPT outlet. Close the handle and verify the flow stops completely with no drips from the transparent plastic body.

Does the Rheem SP12159B package include pipe thread sealant or adapter fittings for the 3/4 in NPT connections?

The box contains only the 3 in long drain valve assembly with 3/4 in NPT inlet and outlet. Thread sealant, tape or any adapter fittings must be purchased separately.
