Poly-Guard Scale & Rust Preventer (Liquid) is specifically formulated to prevent hard water stains, including scale and iron staining in commercial, industrial and residential potable water applications. Poly-Guard forms a protective coating on metal and plastic surfaces preventing hard water stains, scale, corrosion and copper leaching. As a bonus, Poly-Guard also protects pumping pipes and fixtures from calcium and scale buildup.
To eliminate hard water stains, simply inject Poly-Guard by chemical feed pump into the raw water system as close to the source as possible. This product is NSF Certified to meet NSF/ANSI/CAN Standard 60 for drinking water additives.
Available in 1 gal and 5 gal sizes.
Corrosion Control: To get rid of iron and hard water staining, 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. For best results, use dosage calculator to determine the correct dosage for your use.
