Technical Specifications

Service and installation: Shut off the toilet water supply before service. Flush the toilet and remove remaining tank water when working inside the tank. Follow the product instructions, avoid overtightening plastic fittings, and check for leaks and proper flushing after installation. Use a qualified plumber for uncertain fitment or installation.

How to find your model number: Check inside or under the toilet tank lid, on the tank’s inside wall, or on the bowl or inside the tank area; label locations vary by manufacturer. Record every letter and number, then match it to the original part number or manufacturer parts diagram.
