how to winterize spigots

Winterizing your outdoor spigots is crucial to prevent costly pipe damage from freezing temperatures. Frozen water expands, potentially bursting pipes and causing significant water damage to your home. This simple process can save you significant time and money in repairs. Let's learn how to protect your spigots this winter.

Understanding the Risks of Freezing Pipes

Before we dive into the how-to, it's important to understand why winterizing is so important. When water freezes inside your outdoor spigot, it expands. This expansion puts immense pressure on the pipes. The pressure can cause cracks or even complete breaks in the pipe, leading to leaks and flooding once the temperature rises again. This damage isn't always immediately visible, sometimes manifesting as slow leaks or weakened pipes.

How to Winterize Your Outdoor Spigots: A Step-by-Step Guide

Several methods exist for winterizing outdoor spigots. The best approach will depend on your specific setup and climate.

Method 1: Interior Shut-Off Valve (Most Effective)

This is the most effective and recommended method.

Locate the Shut-Off Valve: Most homes have a shut-off valve inside the house near where the pipe goes outside. Turn this valve to the "off" position.
Drain the Line: Turn on the outdoor faucet to fully release any remaining water in the pipe. You might hear gurgling sounds as the water drains.
Disconnect (Optional): If you have access to where the pipe enters the wall and you feel confident doing so, you can disconnect the spigot from the main water supply. This allows for more complete drainage and reduces the risk of freezing. If you aren't comfortable with plumbing, skip this step.
Insulation (Recommended): Once the line is drained, consider adding insulation to the exterior pipe, such as pipe sleeves or foam insulation. This will offer extra protection against freezing temperatures.

Method 2: Exterior Faucet Covers (Simpler, but Less Effective)

This method is easier but less reliable in extremely cold climates.

Purchase Faucet Covers: These covers are available at most hardware stores and are designed to fit snugly over the faucet.
Install the Covers: Carefully place the cover over the faucet, ensuring a tight seal to prevent cold air from entering.
Additional Protection: You can enhance the protection provided by the cover by adding additional insulation like foam or rags around the faucet.

Method 3: Blow-Out Method (For Professional Use)

This method requires specialized equipment and is generally recommended for professional use. Using an air compressor, a professional can blow out all the water from the line, ensuring there's nothing left to freeze. This is the most reliable method, but requires specific equipment and skills.

Frequently Asked Questions (FAQs)

Q: How low do temperatures need to be before I need to winterize?

A: The temperature threshold varies depending on your location and the type of spigot. It's best to winterize before the first hard freeze is predicted, typically when temperatures consistently dip below freezing (0°C or 32°F).

Q: What happens if I don't winterize my spigots?

A: Frozen water expands, placing tremendous pressure on your pipes. This could cause cracks, leaks, or even complete pipe bursts, resulting in costly repairs and potential water damage to your home.

Q: Can I use antifreeze in my outdoor spigots?

A: While some people use RV antifreeze in their pipes, it is generally not recommended for standard plumbing. It's corrosive and may damage your plumbing over time. The better method is to drain the lines and insulate the exposed pipes.

Conclusion: Protecting Your Home from Winter's Freeze

Winterizing your outdoor spigots is a simple preventative measure that can save you from expensive repairs. By following these steps and choosing the method best suited to your needs, you can protect your home and plumbing system from the damaging effects of freezing temperatures. Remember, prevention is always better than cure, especially when it comes to protecting your home against winter's harsh conditions. Don't hesitate to consult a plumber if you're unsure about any part of the process.
