PULSE ShowerSpas introduces their Pressure Balance Rough-In Valve with Chrome Trim Kit! This valve utilizes a pressure balancing mixing cartridge to ensure constant water temperature in response to changes in water pressure (e.g. flushing a toilet). The valve also comes equipped with an adjustable Hot Limit Safety Stop to reduce risk of scalding. The Chrome finish pairs beautifully with many PULSE ShowerSpas including the Kauai, Lanikai, Bonzai, Splash, Aloha, AquaRain, and NatureRain. The Plaster Guard is to be used as a guide during installation.
