Basic Piston Function①Incoming pressure to the upperchamber seals the piston downover the main seat②Moving the handle causes thepiston to slide up, releasingwater into the fixture③The piston re-seats as theupper chamber re-pressurizesAll Sloan Piston flushometers are “non-hold open” designSloan Piston vs Diaphragm FlushometerTraining WebinarProprietary and Confidential8

MaintenanceRecommendationsProprietary and Confidential23

Best Practices No pipe dope No Teflon tape Tighten couplings and covers byhand, then “snug” with a wrench Fixed smooth-jawed wrench Avoid compression wrenches“Snug” – don’t over tighten Carry 100% silicone grease Clean threads with a brass bristlebrush Wet the gaskets before installing Clean with soap and water onlyClean with soap and waterProprietary and ConfidentialUse Genuine Sloan Parts24
