Are the One2Flush and H2O Mizer dual flush retrofit fit kits easy to install?
Yes, but you do need to feel comfortable disassembling a toilet. It is easily a one-person job, but having another person handy within shouting distance could be helpful for some people when removing the tank for installation. The average homeowner, with just a few tools, can install the One2Flush dual flush kit in about 30 minutes. Please note, if your toilet tank has not been removed in the past 10 ten years, you may need to replace the tank seal and hold-down bolts when installing a One2flush dual flush valve. Those repairs kits are also available.
