When temperatures drop well below zero, your well system is at risk. The good news is that a few simple steps now can protect your pipes, your water supply, and your wallet. Click to read our guide on how to winterize your well.

Is Your Well Ready for a New York Winter?

Upstate New York winters are no joke. Between the lake effect snow, the freezing rain, and the temperatures that dip well below zero, our homes take a beating every year. For homeowners who rely on a private well, the stakes are even higher. A frozen or burst pipe doesn't just mean an inconvenience. It can mean thousands of dollars in repairs, water damage, and a serious health risk if your water supply becomes contaminated.

The good news is that a little preparation goes a long way. Before the deep freeze sets in, here are a few things every well owner should do to protect their system and their family.

Insulate Exposed Pipes
Any pipe that is above ground and exposed to cold air is at risk of freezing. This includes pipes in basements, crawl spaces, garages, and well houses. When water freezes, it expands, and that expansion can crack or burst the pipe.

To protect your pipes, use foam pipe sleeves or heat tape on any vulnerable sections. Pay special attention to pipes in unheated areas, as these are the most likely to freeze first. A small investment in insulation now can save you from a major headache later.

Check Your Well House
If your well is housed in a pump house or well house, that structure needs to be as airtight as possible. Cold air seeping in through cracks and gaps can drop the temperature inside quickly, putting your pressure tank, pump, and pipes at risk.

Walk around your well house and look for any openings. Seal cracks and gaps with expanding foam or weatherstripping. If you don't have a well house, consider using an insulated cover over your wellhead to provide an extra layer of protection.

Disconnect and Drain Garden Hoses
This one is easy to overlook, but it matters. A garden hose left connected to an outdoor spigot can trap water inside the faucet and the pipe behind it. When that water freezes, it can crack the spigot or the pipe inside your wall.

Before the first freeze, disconnect all garden hoses and drain them completely. Store them indoors for the winter. Then, cover your outdoor faucets with foam covers or insulated caps to keep cold air out.

Know Your Shut-Off Valve
If a pipe does freeze and burst, every second counts. Water can pour into your home at an alarming rate, causing damage to walls, floors, ceilings, and belongings. The faster you can shut off the water supply, the less damage you'll have to deal with.

Take a few minutes now to locate your main water shut-off valve. Make sure everyone in your household knows where it is and how to turn it off. Don't wait until you're standing in freezing water to figure it out.

Test Your Water in the Spring
After winter has passed, it's a good time to re-test your well for bacteria and other contaminants. This is especially important if you had any system repairs over the winter, or if you've noticed changes in the taste, color, or smell of your water.

The New York State Department of Health recommends testing your private well water at least once a year for coliform bacteria and E. coli. Testing every three to five years for other contaminants like lead, nitrates, and arsenic is also recommended.
