Freeze and Heat Protection for Backflow Preventers in Lawton, OK
Above-ground backflow assemblies are exposed to summer sun and winter cold. Many homes were not built with deep cold in mind, so pipes in attics, exterior walls and garages are particularly vulnerable. 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 for years.
