Toto toilet: 6451 2811, 5743#01 continues to run. How to fix?
The rest of this advice is based on the assumption that your tank inside says ST743S#01. Does it? If so, then I know which toilet you have and thus can point you to a particular flapper. If not, then tell me what it says starting either with ST or MS.
Most likely, you need to change the flapper. This is the one that you need: http://www.walmart.com/ip/Korky-2021...pairs/21799756
Available at some Home Depots: http://www.homedepot.com/p/Korky-3-i...21CM/202666003
And many other fine stores.
Here's how to install it: http://korky.com/PDF/2021BP.pdf
Should take about a minute. Definitely an easy DIY job.
If you cant find the Korky 2021, you can use the Korky adjustable 3" flapper, Model 3060. http://korky.com/Flapper3060BP.html You would then spin that little white band around to "set" it to close at the right time on your toilet. Available at HD and other fine stores. http://www.homedepot.com/p/Korky-3-i...60CM/202183799
