I have one in each of my 5 toilets and they work wonderfully **Q: hydrostop has an adjustable slide on the back numbered 1 to 7. Can find no info on adjustments. Anybody know what the slide does?** A: I don't see any information on it either. I didn't notice it before. I just checked the adjustment and it seems to change how quickly the water exits the tank. It didn't change how much water it released on my toilet but that may be another thing it adjusts. **Q: In the pictures, the flush handle is on the front of the tank. Mine is on the left side of the tank. Is the cord long enough for this application?** A: Thank you for your inquiry. It will depend on the distance from the flush valve location in your toilet to the side where handle is located. The cable cord on the handle is approximately 10-1/2 inches long. **Q: The handle broke off but everything else works. How do I get just the handle?** A: Contact the company as it is warranted ## Customer Reviews ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Easy Peazy *by F***K on Reviewed in the United States on October 12, 2023* The Danco FLT231T Alternative Toilet Tank Flapper Replacement is a terrific innovatiive replacement for the traditional rubber/silicone toilet tank flapper. I don't really understand the mechanics behind how it works, but it works superbly everytime, all the time!! The Danco FLT231T Flapper Replacement is indeed EASY2INSTALL if you have traditional tank components, mine are not - some years ago I replaced the tank parts with Korky replacement parts & the water fill tube barely allowed fitting this unit within the toilet tank; however, it did fit & it works flawlessly. Only time will tell how long-lasting/durable the unit is, but thus far I'm really impressed with the results - based on my experience, I highly recommend this unit for peace of mind to keep the toilet from continuously running and/or over-flowing. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Easy Installation, Handle A Little Tricky, Water Level Adjust Great, Works Great *by S***N on Reviewed in the United States on November 4, 2018* I really like the Danco toilet flapper replacement! It replaced a 10+ year old Danco push-button model that began to habitually leak. The new one was easy to install in just a few minutes, has a very useful and easy to use water level adjustment, and most importantly worked perfectly from the first flush.Here is what I like:+ Everything I needed came in the package+ The instructions were clear and sufficient+ Installation of the flapper replacement is very easy+ The handle is much nicer than the push-button it replaced+ The water level adjustment is easy to set and precise+ No more leakingHere is what I don't as much (pretty minor):- The handle pulled out after installation (just had to push it back in till it "clicked")The handle pulling out appears to be a clip that didn't click in. My toilet has a rectangular opening for the handle and the Danco handle was a tight fit but it did fit. Of all parts of the easy install the handle was surprisingly the most touchy for me.Down sides are very minor and it solved my leaky toilet problem handily in about 10 minutes. At its low price I think this Danco flapper replacement offers excellent value and that gets 5 stars from me. I'm very pleased. ### ⭐⭐⭐⭐ 4.0 out of 5 stars Great replacing for old flapper drains but… *by W***E on Reviewed in the United States on March 9, 2023* Install was easy. The shim helped line everything up and works perfectly. I don’t think I trust the zip tie that holds it in place though. I broke both ties provided in the kit and used a larger one I had on hand. It would definitely be better if it used a stainless hose clamp to install it to the existing flush valve or at least used a nylon nut & bolt instead.
