Review: Exact match, fixed the toilet problem
Review: The standard flush mechanism for the toilet is a two piece, loose fit design which tends to separate from each other frequently resulting in the flush valve failing to activate. It was very frustrating having to remove the lid and reconnect the two pieces every day. With this unit, the cable trigger is easy to install, a 10 minute job at best and has not failed yet since being installed. This was an additional cost as after market equipment but I think Flushmate should make it a standard piece of equipment, even if it adds to the original cost of the toilet system. I should have purchased this in the first place and saved myself a lot of frustration. Highly recommended.
