Do they mean 2.56 gallons per flush, since you need to flush twice for them to work?
Solution: get the cheapest low-flush terlit possible, then replace it with the real thing afterwards 🙂 Maybe there could be money in a toilet rental service. $100 flat fee for delivery, temp installation, and replacement of low-flush bogs.
BTW, what’s up with the 1.28 number? Was some legislator a coder in a past life?
Edit: it looks like the inspection requirement is already in effect since 2014.
