*by J***Y on 20 September 2023*

This was a great price but best of all it worked great in my toilet and was super easy to put in for an old lady of 72 lol the Instructions were excellent very easy to understand and went step by step I highly recommend this to anyone who needs even just a flapper this comes with that to And the best part is it comes with a 5 year warranty So I know I won't have to worry about this part for 5 years The one that came in the tank with my brand new house was only in use a year and a 1/2 Built by cavco In Phoenix Arizona The flipper in it quit holding water And trying to get that flip off The plastic that it was on part of the Flush valve broke off so I still have to replace the one in my spare bathroom so I have a second 1 of these to do that with Because that flipper is crinkling and about ready to stop holding water also it was the right size
