How to Winterize Your Plumbing Before Leaving for the Winter

If you're leaving your New Jersey home empty during the cold months, a little preparation prevents the nightmare of returning to burst pipes and water damage.

If someone will check the house

Keep the heat set no lower than 55°F, and arrange for someone to check the home periodically. Leave cabinet doors open under sinks on exterior walls, and consider a smart thermostat and water-leak sensors that alert your phone.

For an extended absence

For longer absences, fully winterizing is safer. This involves shutting off the main water supply, draining the pipes and water heater, and adding antifreeze to drain traps. A plumber can winterize the system properly so nothing freezes.

Don't forget

  • Shut off and drain outdoor spigots
  • Turn off the water heater (or set to vacation mode)
  • Drain the washing machine hoses
  • Consider shutting the main valve if no one will visit

When you return

Turn the water back on slowly and check every fixture and visible pipe for leaks before assuming all is well. If you winterized fully, a plumber can safely recommission the system.
