High Flow Required

Most machines cannot run these, and we would rather say so here than after you have spent the money.

"High flow" is not a standard. Across the 16 machines we checked it means anything from 26.9 to 45 GPM — six definitions, six tier schemes, and one manufacturer whose "enhanced high flow" delivers less than their standard high flow.

Check the number on your machine's plate, not the word in the brochure. Send us your make and model and we will read it for you.
