My flushometer currently has a A-36-A diaphragm kit in it.I am looking to make it more economical.Will the A-38-A do so?Lower the standing water level

Nick B said on November 23, 2014 | Edit A-36A USE -4.5 GALLONS PER FLUSH /16.9LITERS PER FLUSHA- 38 A USE 3.5 gpf/13.2 Lpf one gallon less

does this only work for Sloan urinals, Im looking for Crane Urinal parts. will this work?

this is not for other brands, only sloan

Does this include all of the "guts" needed to rebuild a urinal flush valve?

Yes, except for the vacuum breaker, and anything below that. Also the shut off itself, which may or may not need replacement.

Does this fit the gem 2?

do not think so, the gem is a cartridge right?
