Officials in the East Bay have warned customers that unprotected water pipes are in danger of freezing.

Some in the Tri-Valley area have already woke up without water this week due to burst pipes, according to the Dublin San Ramon Services District.

The East Bay Municipal Utility District recommends wrapping frozen pipes in a towel and slowly pouring warm, but not boiling, water over them to defrost them. Never use a torch or open flame, officials said.

Homeowners are advised not to try to protect pipes by leaving faucets open, as this wastes water, EBMUD officials said. Instead, they recommend wrapping pipes and shutting off valves to irrigation systems after draining water from the pipes.
