One-inch connections are provided at the 1800 brine valve and brine tank. Local plumbing codes and
flow rates dictate the type of piping used between the brine tank and mineral tank. The recommended
refill rate for a 1,200,000 grain system is 15 gallons per minute. A consideration should be made as to
the type or number of air check(s)/safety(s) installed in the brine tank with these systems.
