Protecting "Forgotten" Pipes

If you woke up to a small geyser in your yard after the overnight freezes, you're not alone.
Brad Winbigler, owner-operator of Brad's Plumbing, says 90-95 percent of the calls he's getting are for
exploding automated sprinkler systems. That's because the vacuum breaker on the system literally blows its top.
"Those vacuum breakers actually hold a little bit of water in them and they don't wrap the top cap part, which is smart because if you wrap it that would be bad because the vacuum breaker wouldn't work when it needs to in the summer. But without protecting that top part that little cap blows off and then next thing you know they got water just spewing out the top."
Overall, Winbigler says he's not getting too many calls about busted pipes inside houses. The calls that do come in are typically attic pipes that are exposed to strong winds coming through.
"Everybody really in Houston gets pretty much an A+, we just evidently didn't get the word out on these vacuum breakers in this particular freeze that was it. Preparedness goes a long way with hurricanes and everything else and people in Houston were real good about protecting most pipes. It's the ones they didn't see or forgot about that got them."
Winbigler says the next time there's another hard freeze, consider wedging your attic stairway open slightly to allow some heat to rise into the attic. And he says it can't hurt to let your exterior faucets drip just a little bit on especially cold nights.
