What backflow preventer repair means in Biola
A backflow preventer sits on the supply line to the sprinkler system and keeps irrigation water from flowing back toward the drinking-water supply. It is exposed to the weather, so seals wear, caps leak and bodies crack. Water spitting from the top or a constant drip means the valve needs attention.
We repair backflow preventer valves in two ways: rebuilding the internals when the body is sound, or replacing the valve completely when it is not. On request, we also install check valves at the lowest points on your property, which stops water from draining out of the low heads after a zone shuts off.
A leaking backflow device in Biola wastes water at the supply line, before it ever reaches a head. It is worth fixing early.
