How to Repair a Pipe Leak
The thin copper pipes that carry hot and cold water in most homes are normally durable and long-lasting, but sometimes develop leaks that can cause severe damage. Pipe leaks are especially common during cold weather, when frozen water in the pipes can cause pipe walls to crack or poorly soldered joints to loosen.
Do-it-yourselfers can sometimes make temporary repairs to keep water pipes in service until permanent repairs are made by replacing damaged pipe and fittings. Temporary pipe leak repairs allow toilets, sinks and other plumbing fixtures to remain in use.
Before temporary pipe repairs are discussed, however, another point for dealing with a water emergency should be stressed: Every occupant of a home, including older children, should know the location of the main water valve and know how to turn it off. Simply turning off the water at the main valve can prevent a burst pipe or other plumbing emergency, such as an overflowing toilet or tub, from becoming a home flood.
There is no standard location for a main water valve, but in homes with basements it is usually near the water meter or water pump. In other homes, the main valve is sometimes under the kitchen sink. If in doubt about the location of the valve, have it pointed out the next time a plumber visits the home.
