Backflow Replacement

What This Service Involves

Backflow preventers are the assembly most likely to crack during a Puget Sound cold snap, especially if a system wasn't fully winterized. A failed backflow can allow fertilizer, soil bacteria, and standing irrigation water to siphon back into your potable supply, which is why Washington jurisdictions require annual testing. We remove the damaged assembly and install a new device that meets your local water purveyor's specifications. Every replacement is followed by a certified test and the paperwork your utility requires.
