Toilet Tank Bank Insert 3-Pack, Water-Saving Device, Saves 95+ Ounces Per Flush, Brick and Bottle Alternative, for Less Efficient Older Toilets to Save Water

They were ok. The first time I filled the bags up, one bag split before I had finished filling it. The other 2 are in my toilets and seem to be good.

I just moved into an apartment so I don’t have anything to compare it to utility saving wise. However I can say it is super easy to set up and install and I hope it will save me money on the long run. It’s a unique product and with it being a 3 pack I might give it out as an office gift for Christmas because who couldn’t use one! UPDATE May 2026: I LOVE these things. Everyone gets one as a gift. I was worried that the reduced water volume could result in the toilet clogging, but I am happy to report that has not been the case once. Also, nothing about these have gotten gross- so strange smells/film/etc. They look just as good as the day I bought them and they have been living in their toilet tank home for about 6 months now. 10/10 I think you should buy these.

Works great, hang on the side, displaces water. Reduces the amount of water used for a flush.

Definitely meets the quality bar, saves water every time you flush

Works as advertised. help save some water bills
