Product was shipped and received overnight.. Product went in easily and worked with no issues.. All the parts came with the filter ( duckbill )

This replacement flush valve is the Flushmate OEM part and it works best for Flushmate pressure tank. The cheap China copy is a knock off flunked. Always buy the Flushmate OEM valve and other replacement parts. Be happy.

Yeah, the fancy toilet was in the house when we bought it 17 years ago and just recently I realized something had started leaking causing it to refill a couple times an hour. I was intimidated by the gear in the tank at first but watched a few videos and bought this flush valve cartridge. Installation was pretty simple and no more leaks. Now I'm seriously considering upgrading the head in the other bathroom.

Ordered this hoping it would fix my flushmate pressure assisted toilet that suddenly stopped flushing. This worked great! Only issue I had was the screw used to tighten the actuator black cap didn't quite fit in the plastic screw hole. Otherwise, problem solved! Flushes better than before.

Once adjusted, it just worked. Positively & reliably. There is some "magic" in this design. Can't tell how it works. It looks like there is nothing wrong with the old one, but that one didn't work properly

Arrived on time, installation was easy. Can’t comment on quality or longevity just yet.

Yes, there are cheaper ones here on Amazon, but they don't work like this official OEM one does. Save yourself some hassle and just order the official part.

Our original flush valve cartridge lasted over 10 years and the o-rings finally wore out. This caused water to continue running after flushing and ran up our water bill. So I purchased this replacement back in February, followed the DYI instructions that Sloan/Flushmate has on YouTube and the problem was resolved. 3 months later, the original problem returned, but this time because top o-ring seal on the button started leaking! A family member of ours is a plumber and finally managed to stop by and check out the toilet. They confirmed that I installed the cartridge properly and came to the same conclusion that I did. The new cartridge is defective! I noticed that some others who left reviews mentioned that they recieved different cartridges. Perhaps I recieved one of the cheap knockoffs? Im not sure. All i know is that this new cartridge has already ceased to work properly and the seller/Amazon can only replace within 30 days, so I'm stuck having to buy a new one again. I contacted Sloan to see if they could do anything about this, but haven't heard back from them yet.

Quedo excelente.

worked great

Got this to fix a leaky toilet that was continuously running between flushes and it worked to stop the leak. Easy to swap out and install the new cartridge.

The product was perfect and was easy to install. Works like new.

Speedy shipping and the installation instructions are to a T.
