Leaving for the Summer: A Leak-Prevention Checklist

• Close the main water valve, or install a remote shut-off.
• Ask a plumber whether to turn off the water heater for your setup.
• Have the AC condensate drain and pan serviced.
• Place leak sensors at the water heater, washer, sinks, toilets, and air handler.
• Replace rubber washer hoses with braided lines.
• Arrange home watch visits and after-storm checks.
• Leave your insurer's contact and the main shut-off location with your home watch.

Why summer is the risky season

Many owners leave in late spring, right before the hottest months and the summer storm season. Heat stresses supply lines and AC systems, and a leak in an empty house can run until fall.

The day you leave

1. Walk the house and photograph each room as a baseline.
2. Run each sink and toilet, then check under them for drips.
3. Close the main valve and confirm the water meter stops moving.
4. Set the thermostat per your HVAC contractor's advice for an empty summer home.
5. Leave keys, alarm codes, and this checklist with your home watch.

What your home watch should check

• Floors near the water heater, washer, and toilets.
• Ceilings under the AC air handler and roof penetrations.
• Musty odors on entering.
• The AC is running and the house is not humid.
• Any storm debris on flat roofs or in drains after a storm.
