What Customers Are Saying
Customers praise this toilet repair kit for restoring function like new, reducing noise, and improving flushing efficiency. Most highlight clear written and video instructions—including QR code tutorials—that make installation accessible for DIY beginners. Many report lasting, reliable performance with toilets flushing quietly and filling faster. However, some encounter fit issues with the tank-to-bowl gasket or flush valve components, particularly with non-standard toilets, and a few note metric bolts that are too short or low-quality washers. Despite these drawbacks, most satisfied customers intend to repurchase or use it on additional toilets.

Would Not RecommendI installed this according to directions; however, it still leaked. I had to call in a plumber who told me that the Korky flapper wasn't flexible enough and so he installed a new (non-Korky) flapper and it worked fine. In the end, it cost me $338 in addition to the purchase that I had made at Lowes. I am disappointed.

Tank bolts are too small and metric.
Dislike. The tank bolts are too small in diameter and are 7mm threads. I removed a nut from the bottom of the tank and the bowel had a washer and thumb nuts fastening the two together porcelain parts. I had to buy a new set of larger diameter bolts that were just like I removed and were not metric. The ones I removed were in bad shape and were not metric.

Worked but only just
Would Not RecommendThe main tank seal is so large and soft that you have to tighten it doen to nearly 1/16” inch thickness to get it to seal and stop leaking. The kit came with 3 bolts, nuts & washer when you only need 2 and was short the rubber seal for a solid water line - you need to purchase the flexible water line that is 3/8 flash eon one end and 3/4 NTP on the other. The nuts for the bolts that hold the tank to the bowl are tiny and not a wing nut- making it very difficult to get a wrench on them, the bol...

The only brand of flush valve I'll use now.
Would RecommendAfter using (and replacing and replacing again) the "other brand" of flush valve, which only seems to last a couple of years at best, I decided to give Korky a try. It's quieter, fills faster, has an easier to adjust bowl fill valve, and lasts longer. And it's made in the USA! I first tried this overhaul kit in the toilet that gets the most use in my house several years ago. It's still working like the day I put it in. Another great thing about it is that you can adjust the maximum amount of wa...
