Our toilets do not flush very well. Meaning that it may take 2 or
more flushes to really flush the ****. The tanks properly fill
and properly release water, but it seems as though there is just
not enough of water to do the job right.

A trick to use on a regular 1.5 gallon tank is to hold the handle down
until enough water enters the bowl to make a whirlpool and carry
everything away.
