Tank Booster Pro with Breaded Hose & Temperature Gauge

SharkBite 24644 – Cash Acme Tank Booster Pro Mixing Valve Kit

The SharkBite 24644 Tank Booster Pro is a thermostatic mixing valve kit engineered to control outlet water temperature from a water heater. It allows the water heater to be stored at higher temperatures—typically above 140°F—while blending hot and cold water downstream to maintain a consistent, safer delivery temperature at the point of use. This supports both scald protection and extended hot water availability without altering the tank size.

The kit includes the Cash Acme thermostatic mixing valve, a 3/4” SharkBite flexible water heater connector, and a 3/4” tee fitting for simplified installation. Designed for copper, CPVC, or PEX plumbing systems, the Tank Booster Pro is third-party certified for performance and safety compliance.

Key Functional Advantages

• Hot Water Storage Efficiency – Allows water heater to operate at higher storage temperatures, improving recovery rate and usable hot water volume
