Flushmate M-101526-F31 System, 1.6 GPF, Fits Most OEM Toilet Tanks | Except Kohler K4404 & Gerber 28-385, Compatible with Flushmate 503 Series and Series III Systems, 5-Year Warranty 93001054

I had previously purchased components for my 12 year old Flushmate attempting to fix the leak, not realizing that the tank itself was leaking. Guess I was trying to save a dollar or two. When I promptly received this, the entire unit, I read the instructions (I had already watched the short video) I removed the old unit, cleaned the tank and whatever needed cleaning, installed the new unit all in 50 minutes. I used the step by step instructions and followed them verbatim and so glad that I did as one of the last instructions is to take a two gallon bucket and place the supply line into it and turn on the water full blast. I couldn't believe the crud that came out of the supply line that surely would have shortened the life of my new unit. I empted the bucket, and did it again just to me sure there was not any more crud in the existing water supply line. The instructions are excellent in that each one has diagrams, pictures and other suggestions and/or recommendations. The Flushmate replacement is much better than the original in that it is quieter, faster, and comes with a new "flusher" and handle that are superb. They even provide the tool necessary to make the installation so much easier, along with new gaskets and other parts to make the job easier.I think it is commendable that a manufacturer make improvements to their products to make them more efficient and easier to maintain. They provide very good instruction and even telephone support if needed. I did not need phone support, as it was much easier to install than I anticipated. I know now that when my other two twelve year old Flushmates need repairing, I will certainly do it right by installing these complete units and be done with it. And, the warranty on these new models is for ten years rather than five years as is on the original.

May need to change the bowl gasket to a new one even if the old one wasn’t leaking.

Working great so far, haven't had a problem worked, right? Right off the bat fit perfect

Works well once installed. But be aware that if you are replacing the unit in a Gerber toilet, you also need to order the Gerber 99-591 tank to bowl gasket. The gasket that's included in this unit does not work with Gerber toilets.

Works great had a plumber install it

Direct replacement for the original I had in my toilet. The one has a -A at the end of the model number. Comes with necessary gaskets to replace. Note the toilet tank needs to be removed to swap the pressure tanks. After replacing the serviceable parts on my previous pressure tank and flush issues persisting off and on a full replacement was warranted.

Replaced easy. Fixed leak.

Returned. Did not fit.

Purchased this to replace an older M-101526-F3 series 503 that started leaking. Installed without any problems and works great. It comes with everything needed except the special wrench and replacement parts for the flush handle. The flush handle parts from the previous Flushmate were easily removed and installed onto the new one.
