During filling, air is transferred from the tank to the trapway, exerting pressure on the water in the bowl. This contained air pressure forces the water in the bowl to fill to a higher level, creating a larger water surface. With more water in the bowl, Proficiency delivers a cleaner and more reliable flush - every time.

Proficiency’s fully glazed trapway provides a smooth, low-friction surface that ensures the bowl is cleared with each flush.

Install and renovate with ease. Proficiency’s compact, sleek design and neutral aesthetics integrate with every bathroom style and preference. By taking up less space, Proficiency leaves more room for vanities, shelving, or cabinets. It’s easier to paint, furnish, and decorate your bathroom with Proficiency!
