Rwc 24644 Tank Booster 3/4 in Mnpt Fnpt Npsh 150 Psi Brass

Product Description

The RWC 24644 is a brass-body tank booster designed to maintain adequate pressure at water heater storage tanks in residential and light commercial plumbing systems. The 24644 connects inline between the supply line and the storage tank, compensating for pressure drop across check valves or backflow preventers that can otherwise cause sluggish hot water delivery. Key specs include a 3/4 inch connection size, a maximum working pressure of 150 psi, and a brass body construction suited for potable water service. Licensed plumbers install this fitting during water heater service calls or new installations.

The 24644 is applied in residential and light commercial domestic hot water systems where a check valve or backflow preventer on the cold supply line creates a closed system condition. In these installations, thermal expansion raises tank pressure and reduces effective flow. The tank booster addresses this by allowing the tank to maintain working pressure without requiring an expansion tank in certain configurations. It is commonly installed at the cold water inlet of storage-style water heaters.

Compatibility

Installation Notes

Installation should be performed by a licensed plumber in accordance with local plumbing codes and the International Plumbing Code (IPC). Shut off the cold water supply and relieve system pressure before removing any existing fittings. Use appropriate thread sealant rated for potable water on all threaded connections. Verify that the installed assembly does not exceed the 150 psi maximum working pressure rating of the fitting.
