Wanted to get some suggestions on best Low-Flow Toilets for Apartment buildings in a C+ building. I've owned a 6-unit for about 6 months now, and the water/sewer bill is higher than expected. RUBS are illegal and individual meters is not feasible at this time.
I'm wondering what people's best experiences with low flow are, reliability, durability, best brands, savings seen, and if I should avoid the extreme low gpf toilets for water savings (0.6-0.8 gpf). Looking to not reinvent the wheel on this one.
