Encyclopedia: Winterizing Your Home
When the weather gets cold, you need to take steps to protect your pipes from freezing. There are three parts to this process:
draining your irrigation system, draining your faucets, and
closing off foundation vents.
Draining Your Irrigation System
- Locate your irrigation valve. This is the rectangular green plastic cover shown in the picture below. It is
probably in your front yard near the sidewalk, close to the water meter (the metal cover in the sidewalk).
- Remove the green cover. Just hook a finger in the small hole and lift the cover straight up.
- Shut off your irrigation water supply. Locate the faucet-like handle on the pipe, as shown in the picture below.
Turn it fully counterclockwise. (Do NOT move any of the other valves or handles.)
- Put the cover back on.
- Turn your sprinklers on for 10 minutes or so per valve or station. This will allow water to drain out of your
irrigation pipes, provided that they slope a little.
- In spring, turn the water back on and check for leaks (puddles on your lawn).

Draining Your Outside Faucets
- Locate your faucet shut-off valves. Every outside faucet will have its own shut-off valve, which looks like
the one in the picture below. These are usually in the garage near the water heater and under bathroom or kitchen sinks.
- Close the valve. Rotate the lever clockwise until it is at right angles to the pipe, as shown in the picture below.
- Open the outside faucet. The water will surge out, and will then stop flowing. (If the water keeps flowing, you
picked the wrong outside faucet for the shut-off valve you closed.) Leave the faucet open until the spring.
- Locate the brass drain nut on the shut-off valve. The nut will be under the valve body, as shown in the picture
below.
- Place a bowl under the shut-off valve. The pipe still contains as much as two quarts of water, so choose a bowl
or tray large enough to hold this amount.
- Remove the nut. Unscrew the brass nut by turning it counterclockwise; you should not need a wrench. The
remaining water in the pipe will drain into the bowl.
- Reinstall the nut. (Make sure the rubber pad is still inside!) Tighten it firmly with your fingers.
- In the spring, reverse the procedure. Open the shut-off valve and watch for leaks at the brass nut; tighten it more
if needed. Go outside and shut off the faucet, which will be flowing full-blast. Finally, go back inside and again check the
brass nut for leaks.

Close Foundation Vents
In the event of extremely cold weather, you should close your foundation vents until the temperature rises again to normal
winter levels. This will protect the pipes in your crawl space from freezing, but will also eliminate the ventilation that
keeps moisture from building up (and hence, helps prevent mold and mildew). Close the vents only when necessary.
To close the vents, sweep any dirt, bark, or other debris from the opening, and then pivot the flap into a vertical
position. When the weather improves, pivot the flap down to horizontal again.
