Bringing a second home back to life starts at the water main, and the trick is to open it slowly. Months of sitting dry leaves joints brittle, and a fast valve can shock a line into failing the moment pressure returns. Crack it open, listen for water running where it shouldn't, and you'll catch a problem before it soaks a wall.
Quick opening-up checklist
- Turn the main water on slowly and watch for leaks.
- Run every faucet and check under sinks.
- Test the smoke and CO alarms.
- Check the washing-machine hoses.
- Restart and check the water heater.
- Restart and check the refrigerator.
- Put in a fresh HVAC filter and test heat and AC.
- Walk through for damp, leaks, and pests.
Turn the main water on slowly
After months dry, opening the main valve fast can pressure-shock fittings and joints. Crack it open, let the system fill gradually, then open it fully and listen for water running inside walls or under the floor, which points to a line that failed over the off-season.
Run every faucet and check for leaks
Open each faucet, flush each toilet, and run the tub and shower, then check under every sink and around the toilets and water heater for drips. Catching a slow leak in the first hour beats finding it after it's soaked a cabinet.
Test the smoke and CO alarms
Press the test button on every alarm and replace any battery that's weak or any unit past the date on the label. These are the first things to confirm before you stay the night.
Check the washing-machine hoses
Hoses that sat under pressure all season can develop bulges and cracks. Inspect them and the fittings for dampness before you run the first load, and replace rubber hoses with braided stainless if they're aging.
Restart and check the water heater
Relight or power up the heater per the manual and give it time to heat. If it's a gas unit and you smell gas, stop, leave, and call the gas utility rather than troubleshooting it yourself.
Restart and check the refrigerator
Power it up, let it reach temperature before you load it, and confirm the doors seal. Wipe out any mustiness from sitting closed.
Put in a fresh HVAC filter and test the system
Drop in a clean filter, then run both heat and cooling briefly to confirm they work before you need them.
Walk through for damp, leaks, and pests
Check ceilings and around windows for water stains, sniff for must in closets and the basement, and look for signs that mice or insects moved in over the vacancy.
Good maintenance rhythm
The checklist gets you through opening day once. Catch off-season damage early by running this routine on every arrival.
- On arrival: turn the main water on slowly and run every faucet to check for leaks.
- On arrival: test the smoke and CO alarms and check the washer hoses.
- First day: restart the water heater and refrigerator and let them reach temperature.
- First day: put in a fresh HVAC filter and test heat and cooling.
- First day: walk through for damp, leaks, and pests.
- If you smell gas: leave and call the gas utility, don't troubleshoot it yourself.
