Corrosion Control:To get rid of hard water stains, Poly Guard is applied
through a chemical feed pump downline from the well pump. Poly Guard is
normally fed at a rate of 1 gallon per 200,000 gallons of
water. The feed rate should increase to 1 gallon per 100,000 gallons in
above normal iron and corrosion water supplies. Follow the procedure for
injecting Poly Guard solution into the water system as specified by the
chemical feed pump manufacturer or supplier.
