If a water pipe breaks, immediately close the main shut-off valve to stop flooding. The shut-off valve can be indoors or outdoors – usually in a basement, crawlspace or garage. If you cannot turn off the main shut-off valve, SPU customers can call (206) 386-1800 and a crew will turn off the water at the meter for a service charge. This phone number is staffed 24/7.
Call a plumber to repair or replace the damaged section of pipe as soon as possible.
Thawing Frozen Pipes
If you turn on a faucet and only a trickle comes out, suspect a frozen pipe. Locate the suspected frozen area of the water pipe. Likely places include pipes running against exterior walls or where your water service enters your home through the foundation.
Keep the faucet open. As you treat the frozen pipe and the frozen area begins to melt, water will begin to flow through the frozen area. Running water through the pipe will help melt more ice in the pipe.
Apply heat to the section of pipe using towels soaked in hot water wrapped around the pipe, an electric heating pad wrapped around the pipe, or an electric hair dryer. Do not use electrical devices if there is standing water. Do not use a blowtorch, kerosene or propane heater, charcoal stove, or other open flame device. A blowtorch can make water in a frozen pipe boil and cause the pipe to explode. All open flames in homes present a serious fire danger, as well as a severe risk of exposure to lethal carbon monoxide.
Apply heat until full water pressure is restored. If you are unable to locate the frozen area, if the frozen area is not accessible, or if you cannot thaw the pipe, call a licensed plumber.
Check all other faucets in your home to find out if you have additional frozen pipes. If one pipe freezes, others may freeze, too.
