Backflow preventer leaking — San Francisco, California
A leaking backflow preventer can waste water, cause low pressure, and — if it fails completely — allow contaminated water to flow back into your drinking supply. Most municipalities require annual testing, and a licensed plumber can repair or replace the device to keep your home compliant and safe.
Waarom dit veel voorkomt in San Francisco
