Why the first freeze catches so many houses
Autumn in Parker is often mild and sunny right up until it is not. A warm week encourages people to keep watering, leave hoses connected for one more wash of the car, and put off the sprinkler blowout. Then a front drops in from the north overnight, and the parts of the plumbing that sit outside or at the edge of the house are caught full of water.
The damage from that first freeze often stays hidden for months. A cracked sillcock tube or backflow body may not show itself until the first watering in spring, by which point the connection between the leak and the October night is easy to miss. Doing the outside tasks early, and the indoor checks at the same time, removes most of that risk in one afternoon.
Outside the house
- Disconnect every garden hose, splitter, timer and quick-connect from hose bibs.
- Open each outdoor faucet briefly with the hose removed so the tube drains, then close it.
- Close the indoor irrigation shutoff and arrange the sprinkler blowout.
- Drain or cover the irrigation backflow device according to its type.
- Clear snow, mulch and stored items off any outdoor meter pit lid.
- Check that foundation vents for any crawl space are closed or covered for winter.
- Look at the high-efficiency furnace and water heater vent pipes outside and keep the area around them clear.
Garage, basement and inside
- Test the main shutoff by turning it partway and back; replace it if it is seized.
- Tag the main and show everyone in the household where it is.
- Check the garage overhead door seal and the weatherstripping on the house door.
- Look at the garage ceiling below any bathroom or laundry above it for gaps around lights and hatches.
- Inspect heat cable on any exposed lines and confirm it powers on.
- Replace washing machine hoses or toilet supply lines that are old, bulging or corroded.
- Put a battery in a simple indoor thermometer and keep it near the coldest plumbing wall.
- Write down the spots that froze in past winters and add them to your cold-night plan.
