Irrigation Backflow Preventer Installation in Mount Pleasant
Sprinkler and drip systems are one of the most common sources of cross-connection risk because they sit in soil with fertilizers and pesticides. Many systems use a pressure vacuum breaker or a reduced pressure assembly installed above grade. We size and install the correct device and set it at the required height. Insulated covers or enclosures help protect it from weather damage and theft.

Freeze and Heat Protection for Backflow Preventers in Mount Pleasant, SC
Above-ground backflow assemblies are exposed to summer sun and winter cold. Before a forecast freeze, disconnecting garden hoses, covering hose bibs and letting a faucet drip is usually enough to protect a home. Freezing can crack bodies and bonnets, while UV exposure breaks down plastic parts. We install insulated pouches, heated enclosures or lockable cages as needed. Protecting the assembly helps it pass testing and last longer.
