Low flow toilets. Don’t get me started. Over the last 30 years I have had about seven. They use half the water per flush. The problem is that I never had one that I did not need to flush three times. Some required four. The refill rate was so slow that I have wasted a LOT of time standing and waiting to do the next flush. Oh how I wish I could give the greenies that pushed this a head swirly from flush 1 through flush 4.
“Low flow toilets.”
There are what I believe are flush assist pressure devices for low flow toilets.
