Will a five gallon tank work on the new toilet bowls (1.5 gal. flush)?

Answer 1

What you have to look at is if the tank will match up with the bowl, mainly the bolt pattern. All brands are different. Kinda like that "buy ours" type of product proofing. Some also use different flush valve sizes. The water volume might not be enough to flush properly for what the bowl was designed to do. Even though it seems simple they actually have alot of engineering behind commodes. Its probably easier to just get a whole new tiolet. If your concerned about how much power will be behind the flush without spending a mint, look into the gerber avalanche, or kohler has a newer model. They both run off 1.6 gal per flush, but the flush valve is 3" instead of the traditional 2" and can handle a whole lot more crap, with out breaking your wallet.

Answer 2

Definate maybe. See, it all depends on the connection on the bottom of the tank and the bowl. If these line up so you can attach the tank, then all should be well. Note that you will end up flushing a lot more then the 1.5 gallons, and the flush won't be any harder, but should last longer. It also will not change the water level left in the bowl after the flush, this is set by the design of the bowl's trap.

Answer 3

yes, buuuuuuuutttttttttttt....
it is designed to work on a 1.6 gallon surge of water, & this will not stop it from clogging easily like every other 1.6 gal toilet. The throat / orifice was made smaller so the siphon would begin with less water hitting the bowl!

Answer 4

yes
