Should I Drain My Water System Before a Hard Freeze?

Preventing Frozen Pipes

A hard freeze can cause water in pipes to expand and rupture, leading to costly repairs. Draining your water system is a simple and effective way to prevent this. To drain your system, turn off the main shut-off valve and open all faucets to allow the water to drain completely. Check the temperature of your pipes: if they’re exposed to outside elements, drain them if they’ll be below 20°F (-7°C).

Protecting Plants and Irrigation Systems

Frost can damage plants and irrigation systems. To protect them, drain the water from irrigation systems and bring potted plants indoors or cover them with a frost blanket. If you can’t move plants, wrap the pot and plant in burlap or a sheet to insulate them. For irrigation systems, drain the water and use anti-freeze to coat the pipes and prevent damage.

Preparing Your Infrastructure

A hard freeze can also damage your home’s foundation and infrastructure. To prepare, seal any gaps or cracks in your home’s foundation and walls to prevent water from seeping in. Check your roof for loose or damaged shingles and repair any issues before the freeze. Additionally, consider installing a freeze-resistant frost-proof spigot or frost-proof sill cock to protect your outdoor faucets.
