PREVENTING PIPE BREAKS Prevent Pipes From Freezing And Breaking W hile we know in winter to bundle ourselves up to keep warm, many people forget to make sure their pipes stay warm as well. When ice forms in a pipe, it does not typically cause a break where the ice blockage occurs. Rather, following a complete ice blockage in a pipe, continued freezing and expansion inside the pipe causes water pressure to increase downstream—between the ice blockage and a closed faucet at the other end. Usually the pipe bursts where little or no ice has formed. will freeze and break if the hose is left attached. • • During severe cold weather, resist the urge to lower your thermostat to save money while you are gone for the day. Open the doors to kitchen and bathroom cabinets under your sinks so heat from the room will help warm the pipes. • Running water doesn’t freeze very readily. During severe cold weather, keep a stream of water trickling out of faucets or spouts attached to vulnerable pipes. Here are some tips to help avoid this common cause of winter property damage: • If you have a sprinkler system, drain all outdoor pipes and turn off the water supply to the system. HOW TO PREVENT FROZEN PIPES • Pipes that have frozen in the past or near exterior walls are obvious candidates for special attention. WINTERIZE IF YOU’LL BE AWAY FOR AN EXTENDED TIME • Turn off the water supply at the main shutoff valve by the street. • Insulate areas where vulnerable pipes are located. • • When insulation isn’t enough, consider pipe wrappings embedded with electrical coils (heat tape) that provide an outside source of heat. Remove garden hoses from outside faucets and open these faucets to drain them. • Drain the water heater. Turn off the pilot light on gas water heaters and be sure to turn off the electricity to electric water heaters before you drain them. • Remove hoses from outside yard faucets. The faucets can’t drain properly with a hose attached and • Use an air compressor to blow any trapped water from the water pipes. Open all faucets and leave them open. This will help keep condensation from freezing and bursting the water lines. • Flush all toilets (to empty the tank) and every faucet (to drain water from the pipes) in the home, including outdoor faucets. • Empty all toilet bowls by siphoning or bailing and sponging. Pour a mixture of food-grade antifreeze and water into all toilet bowls and the traps of all sinks, showers, and bathtubs. Don’t drain these traps. The water in them keeps sewer gases out of your house. • If your water supply is from a well, switch off the pump and drain it along with the above-ground pump lines and the tank. WHAT TO DO IF A PIPE FREEZES • To prevent a frozen pipe from bursting, open the faucet it supplies water to. Then add heat to the area where the pipe is located. • Turn off the water supply to that line. • If a pipe does burst, immediately turn off the water to your home. • Know where your main water emergency shutoff valve is located. + 25
