Flushmate M-101526-F3H1 Complete Replacement System: 1.28 GPF System for Two-Piece Toilets, Intended for All OEMS except Kohler K4404 and Gerber 28-385 Tank, Quiet Operation

When these first came out in consumer toilets way back, I'd say in the late '80's or '90's maybe, I had to have it. A couple of years later I bought a 2nd for the other bathroom. I sold the house in 2020 and they both were still working perfectly. I never had a problem, never had to replace a part. They just worked. Now, here I am today, 2023-10-21, and I installed a toilet with a Flushmate 504 model, six years ago this past September. Last week it began to make a squeaking noise right where it usually shuts off. The next morning I wake up and the squeak is continuous and I look into the tank and see not quite a quarter inch of water. The tank should never show water in it. Long story short, I ended up buying a new 504 unit. This after I had bought a cartridge to hopefully fix the old original one. But, here's the kicker. After replacing both clamps at the hose ends there was still a slow leak at the supply valves. Neither Amazon nor the manufacturer web site had any available. Not wanting to spend days shopping around the local plumbing warehouses and other places, I just bought a whole new unit here. It was easy to bolt in and adjust per the instructions and I am once again a happy camper. I am going to keep the old unit in the box that the new one came in in hopes that one day I will be able to order and or buy the lower supply valve piece. As I know the units made today will not last as long as the first ones I had bought. Hopefully, the lower supply valve piece will become available and this is not a piece that the manufacturer does not sell as to help them sell more of the whole units. I hope this helps you in some way. I still love the Flushmate powerflush!

Excellent product. Easy to install and works very well. So far, I have ordered 3 and they work amazing.

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.

Works great and was not hard to replace the pump.

Works great. Fits perfectly. 4 stars for noise. I replaced my 20 year old 503 and this one is super loud compared to the discontinued version. 20 minutes to install

We've had 2 of these toilets for nearly 20 years. They crap out (pun intended) about every 5 years. I used to fix them with just the valve kit but over time I've realized when the valve goes, the pressure container ain't gonna last more than another year or so. And since it takes about an hour to fix either way, plus the tank kit has the whole valve assemblies already in place and pre-adjusted, that's the fastest, easiest, and most reliable way to get the toilet back up & running for years.

I was looking for a video or explanation of this product that explains if I buy the complete set, do I need to adjust it after installation or not? I couldn't find anything..... That's why I write this review.... If you buy the parts, like valve or .... you must be educated about the product, but if you buy the hole of it, you just need to install it.... That's it.... Easy peazy.... Do not waste your money for repair...

WOW!!! I am very let down. 1) There should be "DIMENSIONs" shown SOMEWHERE. 2) There should be a "PARTS INCLUDED" listing SOMEWHERE. I digress - This unit DOES NOT FIT ALL TANKS. If your toillette tank is less than 14" side to side, the Flushmate is too wide. Next - the unit comes WITHOUT any flush handle hardware. Hardware will cost an additional $41.99. Much to my demise I am returning the Flushmate and didn't check if the cartridge wasn't already installed but "THAT" would have been another $43.99. So to get the flushmate installed the original $166 would end up being $251.97. Not to mention the pain of waiting for all of the "now needed" accessories to arrive. This item is a VERY EASY installation (all things considered) but there were no instructions or pamphlet discussion about the cartridge. I learned (thanks to YOUTUBE) the catridge has to be calibrated which is easy enough but what is the frequency to change it out? Keep the original packaging too! My "RETURN WARNING" was "If not double boxed I'd be charged a restocking fee". Such a neat product but failed miserably gouging for more money from the buyer than necessary. If you really want one HOME DEPOT carries one at $202.00 "WITH" dimensions listed.

Ça fonctionne parfaitement Merci!

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.

Was a perfect fit. Product is great. The cost is not

Product as advertised. Works well

Good product
