Backflow prevention devices keep contaminated water from flowing backward into Sherwood’s clean water supply. Pulaski County and Arkansas Department of Health regulations require annual testing of all backflow prevention assemblies on residential and commercial properties connected to Central Arkansas Water.
Why Sherwood Properties Need Professional Backflow Testing
Properties across Sherwood sit on Pulaski County sandy clay with limestone underpinning. Ground movement from this soil type puts stress on water service lines and the backflow assemblies installed near property meters. Older homes near Sherwood Forest neighborhood and the Highway 107 commercial corridor are especially prone to backflow valve failure due to aging copper and galvanized connections that develop micro-leaks over time.
