We compare published specs, MaP flush-test scores, certifications and aggregated owner reviews. We do not physically test units in a lab. Our goal is to surface the data that actually predicts a strong, clean, reliable flush, then present it clearly.

0.8 / 1.28 GPF Check price on AmazonJump straight to the flush style that fits your bathroom and your priorities.
A strong flush combines bowl design, a wide glazed trapway and an efficient flush valve. A high MaP score signals it can clear more waste in a single flush with less water.
MaP (Maximum Performance) is an independent flush test measured in grams of waste cleared in one flush. Higher is better. Scores of 800 to 1000 grams indicate a very strong flush.
For many homes, yes. A dual-flush lets you use a lighter flush for liquid waste, which can meaningfully lower water use over a year while keeping full power available when needed.
