Danco HYR451T HyrdroRight Universal Water-Saving Toilet Repair Kit with Dual Flush Valve, Lever Handle, White - $6.94

I purchased this kit approximately three years ago and it has worked flawlessly. I am about to update a couple more toilet tanks and noticed the price drop. These kits are typically well over $25, so this is a STEAL at this price!!! As is the usual with Amazon, they probably won't have many units at this price, so get them while you can. Good luck!
