Water & Wastewater

Cold weather and wind chills are here. This means we can expect frozen water pipes and water damage if exposed areas aren't properly insulated or we aren't careful about winter heating. Here are some problem areas, warning signals and tips to minimize the chance of freezing water pipes.

Problem Areas

Inadequate Heating in Uninsulated or Uncovered Outside Pit
Pipes Near Broken or Open Basement Windows
Pipes Near Exterior Wall in Unheated Room
Pipes Near the Foundation or Cracks in the Basement Wall
Pipes Under Kitchen Sinks or Cupboards
Unheated Crawl Spaces and Equipment Rooms

Warning Signs of Freeze

Discolored Water at a Fixture
Extremely Cold Piping at a Fixture
Low Water Pressure at a Fixture
Sputtering Sound When Opening a Fixture
Unusually Cold Water Temperature (Less Than 35° F) at Any Fixture
Unusually Low Water Flow at a Fixture

Thawing Frozen Pipes

It's safest to use hot air from a hair dryer or exhaust from a vacuum cleaner
Use heat tape, but with caution and following the manufacturer's instructions explicitly, and unplug when finished

Prevention

Check Water Temperature and Run a Little Water if Unusually Cold
Insulate Walls Near Exposed Piping
Repair Cold Air Leaks to Reduce Drafts on Piping and Meter
Run Small Amounts of Water From Highest Faucet Until Full Flow Returns
Shut Off and Drain Outside Water Faucets Before Freezing Occurs

Caution

Be careful if a pipe is cracked, it will spray water into electrical appliances when thawed.
Check and clear drains to prevent basement flooding in case of pipe burst.
Know where the main shut-off valve is located so you can turn it off quickly in case a pipe bursts.
To prevent fires, never thaw with an open flame or torch.
