Is it possible to install a pressure-assist unit (e.g. Flushmate) in an existing, standard toilet tank or is a new toilet equipped with a pressure-assist unit required? If a unit can be installed, where can these units be purchased?

Hi Tbar

No, a pressure assist toilet is a very specific toilet with parts/components that can not be interchanged with other toilets.

If you want a pressure assist toilet you'll need to purchase both the pressure assist toilet tank and the matching pressure assist toilet bowl.

Is that what you needed?
