We recently moved into an older home, I had three toilets to fix. I first put this contraption on one toilet, and it seemed to work OK. So I decided to use it for the other two. After installing one unit, I found the "flapper" valve was not staying in place on the unit itself (faulty manufacturing), resulting in a toilet would not stop running (we had to use the water valve at the wall to fill and use the toilet). Figuring out the problem took some time and wasted quite a bit of water. I finally returned it for another. After installing it, I could not set it properly so that it would work each time correctly. The third toilet has never really worked at all, requiring a full flush as the half-flush never performed properly. Now after several weeks, the original unit in the first toilet is having problems. In addition, as others have mentioned, I have had much difficulty in getting the sticky-gasket material to seal completely. Two of the units continue to have leakage, whereby every several hours they will run shortly to top off the tanks. So after much futility, I'm wondering how Lowe's will react if I return these. BTW, I am an accomplished handyman, capable of completing fairly involved projects (replacing main water valves, replacing drywall, masonry/stucco work, welding, car repair, etc), so it's not like I don't know what I'm doing. I also have a PhD in electrical engineering, working in product design and development. Noting my experience, capabilities, and background, I hope you don't make the same mistake I did.

**Updated with 5 stars for customer service response**

I purchased this product a few months back (different retailer), but encountered constant leaking that drains the tank slowly. The leaking is caused by a faulty flush seal, the light-grey, rubber ring that is supposed to seal the tank-to-bowl connection. This seal is very flexible and easily distorted. It pulls out of the groove in the black circular piston on the flush valve. It has to be pushed back into place for it to work correctly. This happens appx. once ever week or two. It was quite an annoyance, but easily fixed once I discovered the problem, and not worth a one-star review!

I got sick of this constantly happening. I emailed the company about the issue. They were very helpful and shipped me complete replacement kit, free of charge, when all I wanted was a replacement seal! The seal on the new version, which had new packaging, was clear plastic, and much firmer. I have been using this version for over a month now, with no issues with leaking. Thanks, Fluidmaster, for prompt and generous customer service!

If you purchased the older version I had, the package will have the "DuoFlush" logo in white font on dark blue background. The newer version has the "DuoFlush" logo in green and blue font on a white background. The newer version works exactly as advertised, and I have not run into a single problem with it!

**Original review, applies to old version ***

I see lot of one star reviews due to constant leaks after flushing. I have found that the problem isn't the flush cable, but the seal in the flushing mechanism. The seal pulls out of the seating from time to time. To fix the issue, turn off the water, pull the mechanism off the base, and check the circular seal.

Having purchased Duo Flush system conversion kit and installing it with ease, we were dismayed to discover that it did not seal well, resulting in seeping from the tank and the bowl and refilling every several minutes to refill the tank. Took it apart three times and finally got it to seal, at least it is not seeping as fast. It looks like the angled seat adapter is off-kilter. Oh, well. It seemed like a good idea at the time.

***IF YOU BUY ONE OF THESE, READ THIS BEFORE INSTALLING!***

The instructions seemed straight forward. You were instructed to install the flush unit first. That was OK except that in order to conform with the direction of "having one side of the flush unit face the flush handle" the unit was pinched between the side of the tank and the fill tube and such did not seal well. This caused the unit to not fill completely and leak continuously. Took the unit apart, turned it about 70-80 degrees, and viola'! It fit fine. Next comes installing the fill unit and connecting it to the flush unit. Why on Earth they don't they have you connect the two first is mind boggling! It's impossible to get your hand in there and connect this small, tight fitting hose to a small nipple. Again, took the unit out, disconnected the other end of the hose from the fill unit, connected the hose to the flush unit, installed flush unit, installed fill unit, attached hose to fill unit. Bam. Done. Easy. Once again, (and this eats me to the core as a fellow engineer) an engineer wrote an instruction manual without ever installing/using the unit first! (GET OUT OF YOUR CUBICAL AND FROM BEHIND YOUR DESK, AND USE THE PRODUCT!)

All that said, it would not matter if it didn't work, but it does, and it does well. Yes, you MUST ADJUST THE FILL LEVELS for the full and half flush or the the unit won't work properly (see other comments; user/installer error). I must say, we have 20 year old Kohler low volume flush toilets that stink. They WERE always getting plugged, until now. This full flush works very well. Ditto the half flush (OK, I have it turned one or two notches higher than I need so to be able to flush two or three leaves of toilet paper with liquid waste. (You know what I mean...
