NO one has yet mentioned the government’s foray into to toilet design. The premise is wrong to start with IMHO. Would someone explain to me how you waste water. Humans consume it for life, but we exhale vapor and excuse the expression, urinate the remains which goes back where it came from. Water can neither be created nor destroyed. No one but God himself knows the limit on the supply, if indeed there is a limit, and I suggest there will be sufficient for as long as earth remains habitable for man.
Government begins with the same letter as God, but any similarity after that, is purely coincidental.
As you say, there is no shortage of water.
Only cheap water.
Reducing the amount of treated drinking water that it takes for three hundred million people to flush their toilets and at the same time reducing the same amount of sewage water that has to be treated and cleaned is a great benefit.
Using up to seven gallons to flush a toilet just isn’t necessary, the mistake the government made was imposing the standard before the industry was up to the task but now those problems have been solved so the issue is over.
The bathroom did not reach final perfection in 1930.
If you are having problems with low flow toilets I strongly recommend Toto brand toilets. We built a new home a couple of years ago and used Toto toilets throughout and have had zero problems whatsoever. In our old house we had nothing but problems with poor flushing low flow toilets. Constantly clogged... In that house we had to have a plunger next to each toilet at all times. I don’t even know where all the plungers are in the new house... They don’t get used anymore...
