American Standard M952100-0070A Pressure Balancing Unit for Single-Control Tub/Shower Valve

Keep shower temperatures steady, even with pressure changes

The American Standard M952100-0070A Pressure Balancing Unit is designed to maintain a consistent output as hot and cold water supply pressures fluctuate. In everyday use, this helps prevent sudden temperature swings that can disrupt your shower experience.
