The Spring Water - 1 has a 30 lbs. blend of high grade coconut shell carbon and coal based carbon in a 9 X 48 tank. It features a Fleck 5600 automatic backwashing valve that can be set for the number of days between backwashes.
Upgrading to the ProFlo or 7000 valve allows more flexibility in setting the number of minutes of backwash and forward flush in each cycle. Regular backflushing dramatically increases carbon life and prevents channeling. The Spring Water Carbon Systems reduce taste, odor, color, chemicals, chlorine, chlorination byproducts (THMs) and low levels of iron and hydrogen sulfide.
System comes standard with Fleck 5600 valve.
Plastic bypasses have the highest flow rates. Brass bypasses are nickel plated. Stainless steel bypasses have integral yoke with either 3/4 or 1 threads.
7000 Valve has 1 1/4 inlet and outlet connections and the highest flow rates.
ProFlo valve and 7000 valve both have the advanced SE microprocessor controller and easier programming than a 5600 valve.
ProFlo has idential flow rates to the old style 2510 valve with the addition of a microprocessor controller.
