As for filtration of domestic water systems, we offer Eaton Filtration, featuring 304 and 316 Stainless steel bag filtration for domestic systems from 50 gpm to 5000 gpm; and if you don't like changing bags out, Eaton has self-cleaning backwash systems using strainers, not sand, so you can clean the water up as much as you like as, down to 10 micron! The system just cleans like it's nobody’s business, and when the onboard sensors detect the strainers can't handle anymore filthy New York water, they clean themselves. Anyone that says New York's water is the cleanest water in the world has never seen these systems work!
