ABSOLUTE JUNK FROM CHINA
This piece of junk replacement part lasted approximately 50 flushes before it began to fail. I talked to a Flushmate representative sometime in JUNE after struggling approximately 6 weeks with a toilet that 50% of the time would not stop the water from constantly running, consequently the tank rarely filled properly. He told me he gets this type of call all day long, and wasn't surprised to hear from me on this issue since I didn't use an OEM part. His solution of course was to ONLY USE FLUSHMATE GENUINE PARTS made right here in the good old USA. As a final resort before getting rid of the the toilet I took his advice since the toilet wasn't more than 7 years old, and otherwise in good shape. I am happy to say, he was absolutely right, and I will never make that mistake again pertaining to this product. The cost of this part was no different than the cost of the junk I purchased from China on this website, $35. The only difference was I had to pay an additional $7 for shipping. Hopefully the OEM part will last as long as the original part and once it fails this time I will know exactly how to act.
