We help you do your part in keeping our water systems free of contaminated and/or polluted water by providing expert testing and repair of backflow preventers. The Safe Drinking Water Act of 1974 mandates that all commercial water taps, commercial irrigation systems and multifamily residences have backflow prevention assemblies installed downstream of the water meter to prevent backflow of water from backsiphonage or backpressure. Additionally, the SDWA mandates annual testing and certification of these assemblies. The Colorado Department of Public Health and Environment mandates that your water provider track the certification data.
