Protect Every Drop
Imagine 200 toilets in a multifamily building phantom leaking at the same time.
Nearly 50% of the water flowing into your multifamily building goes down the toilet. One leaking toilet can waste up to 200 gallons every day. This amounts to over 1 trillion gallons of water wasted per year in the US alone.
