Nuked my toilet… significant damage was done. Whole family panicked, not me. Walmart delivered this kit in 58 minutes. From there I was able to demonstrate value to my family beyond just producing destructive dumps and completely repair the toilet in about 35 minutes. Huge win, great kit 10/10 saved my marriage

Everything you need for toilet repair in one kit

I like this kit as it has everything you need to repair anything in the toilet tank (water closet) that you would ever need. Fluidmaster is considered a top brand for toilet parts and prefer them over other top brands. Be sure you know if your drain tube in toilet is 2" or 3". Most newer toilets use a 3" hole whereas my 30 yo toilets in my home are all 2". You can buy this same kit in the 3" size if that is what you need. Pricing is higher on the 3".

Great price and all inclusive solution

This kits comes with pretty much everything. I was looking for tightening tool. And the tool itself cost $8 and wasn't even available. This kits comes with all the tool you needed so it was a no brainer for me. And the price was much better compare to Lowes and HomeDepot.
