Low GPF Toilets, are they worth it

[Dick Rosen]

Regarding any class apartment where the owner is likely responsible for water/sewer. Do feel the lower, 1.28gpf or less toilets are worth putting in even if you don't currently need a replacement. I've had plumbers tell me that they will usually increase water consumption because multiple flushes are needed or they hold the lever to allow extra water to run during the flush. What's your thoughts?
