So far, the pipes are holding.
East Bay water officials say they didn't receive an unusual number of calls over the weekend for damaged water pipes despite 30-degree overnight temperatures in some communities.
East Bay Municipal Utility District crews went out on 30 calls over the weekend from homeowners who said their pipes had frozen, according to district spokesman Charles Hardy. That's the highest number in any one day this winter.
However, Hardy said EBMUD crews only received 13 calls this past weekend for pipes bursting. That is slightly below normal for a day in January.
It looks like much of the East Bay will endure at least a couple more days of freezing overnight temperatures.
The National Weather Service forecast calls for temperatures to drop into the low 30s on Monday and Tuesday nights. Highs on Tuesday and Wednesday are only expected to be around the mid-50s.
On Wednesday night, the lows are expected to rise a bit to the high 30s with dayside highs in the upper 50s on Thursday. That pattern is expected to continue until early next week.
Utility districts recommend covering exterior pipes and hose bibs to prevent water from freezing or pipes from bursting.
The Contra Costa Water District also has tips on how to prevent pipes from freezing or bursting and what to do if they do.
If a pipe does burst, the most important thing is to turn the water off to your house to prevent water from continuing to flow. Repairs can come later.
There is usually a valve on a front faucet where you can do this.
If that doesn't work, call EBMUD to come out and shut off the water at your meter. Don't attempt this yourself. You can hurt yourself or break the valve if you don't have the proper tools.
