Be Water Wise, Winterize
How to Prevent Frozen Water Pipes
Frozen Pipes
Any water pipe exposed to temperatures of 32ºF or below can freeze. As anyone who has put a bottle of water in the freezer can attest, freezing water expands (by 9% actually). Expansion of water as it freezes can generate enough pressure to burst pipes and fixtures. As those frozen pipes thaw, the water may flood your home, costing money in repairs and on your water bill. Pipes in attics, crawl spaces, and unheated rooms are particularly susceptible to freezing.

All irrigation systems must be shut off and winterized November 1st through April 1st.

the Winterization Guide with step-by-step instructions.

Stop and Drain Valve
All homeowners who plan to be away for more than a day should take the following steps in preparation for winter weather:
  • Drain your water lines and shut your water off at your stop and drain valve (also called a stop and waste valve). Do not shut off your water at the meter. It is a crime!
  • Drain all indoor plumbing.
  • Disconnect and drain outdoor hoses. Ice formed from a single, hard overnight freeze can burst either the pipe or the faucet. 
  • Mark your stop and drain valve with a tall stake, wire, or pipe so that you can find it in the snow.
  • Only use a stop and drain valve key, called a T-bar, to shut off your water. If you don't already have one, you can pick one up at a local hardware store. Keep the key where it can be easily located in case of emergency.
