How to use

Before installation, isolate the water supply to the cistern and drain the tank. Remove the cistern lid and extract the old mechanism according to the cistern manufacturer's guidance. Install the replacement flush mechanism in the same position, ensuring seals and connections are seated correctly and the device is aligned with the flush lever or push button linkage. Reconnect the water supply and allow the cistern to refill, then test flush cycles and adjust float or seal positions as needed to achieve correct water level and reliable flushing. Follow any specific instructions from the cistern technical documentation.

Usage recommendations

Verify compatibility with your cistern model before purchase. Use basic hand tools and, if unsure, consult a qualified plumber. Periodically inspect seals and connections for wear and replace parts as needed to maintain efficient operation and avoid leaks.
