Vacant Home Plumbing Winterization Guide

Leaving your home vacant during the winter months requires careful preparation to avoid plumbing disasters. Frozen pipes, cracked P-traps, and water damage can wreak havoc on a vacant property, leading to costly repairs. At Roto-Rooter, our professional plumbers specialize in protecting homes from winter’s harsh conditions. Follow this guide to winterize your vacant home and ensure your plumbing stays safe while you’re away.

Step 1: Shut Off the Main Water Supply

The first step in winterizing a vacant home is turning off the main water supply. This prevents water from flowing into the plumbing system, minimizing the risk of frozen or burst pipes.

Locate the Main Shut-Off Valve: Usually found near the water meter or where the main line enters your home.

Turn Off the Valve: Rotate the valve clockwise until it’s fully closed.

After shutting off the water supply, open all faucets to drain any remaining water from the system. If you’re unsure where your shut-off valve is located or how to operate it, contact a professional plumber for assistance.

Step 2: Drain and Blow Out the Pipes

To ensure your pipes are completely clear, use compressed air to blow out any water that might be left behind:

1. Open Faucets: Start with the faucet furthest from the main shut-off valve and work toward it.

2. Attach an Air Compressor: Connect the compressor to a faucet or hose bib.

3. Blow Out Water: Run the air compressor until all water is cleared, leaving only air in the pipes.

This step is particularly crucial for outdoor water lines, irrigation systems, and pipes in unheated areas of your home. A plumber can help ensure this process is done effectively to prevent freezing.

Step 3: Add Antifreeze to P-Traps and Toilets

Even when drained, some water will remain in your P-traps and toilets. This water can freeze and cause damage. Protect these areas with non-toxic, RV or plumbing-specific antifreeze:

P-Traps: Pour antifreeze into sinks, showers, and floor drains to replace any remaining water.

Toilets: Drain the tank completely, then pour antifreeze into the bowl to prevent freezing.

Avoid using automotive antifreeze, as it is toxic and not safe for home plumbing systems. If you’re not sure which antifreeze to use or how much to apply, consult a plumber for guidance.

Step 4: Insulate Vulnerable Pipes

Pipes in unheated areas, such as crawl spaces, basements, or garages, are especially susceptible to freezing. Insulate them with foam pipe sleeves or wrap them in heat tape to add an extra layer of protection. A plumber can recommend the best materials for your home’s specific needs.

Step 5: Turn Down the Heat

Although your home will be unoccupied, it’s crucial to maintain some level of heat to prevent freezing. Set your thermostat to at least 55°F. This helps keep the air warm enough to protect pipes without significantly increasing energy costs.

Step 6: Check the Water Heater

If your water heater will be unused, drain it completely to avoid freezing damage. Follow these steps:

1. Turn off the water heater and let it cool.

2. Attach a hose to the drain valve and empty the tank.

3. Leave the drain valve open until you return to ensure no water remains inside.

If you need help draining your water heater, a plumber can handle this for you safely and efficiently.

Step 7: Perform Regular Inspections

If possible, have a trusted neighbor, friend, or property manager periodically check on the home. They can ensure the heat is running and spot any potential plumbing issues early. If a problem arises, contact a plumber immediately to prevent further damage.

Step 8: Upgrade to Winter-Specific Hose Bibs

Standard hose bibs are vulnerable to freezing, but upgrading to winter-specific or frost-free hose bibs can provide added protection during the cold months. These specialized outdoor faucets are designed to prevent freezing by keeping the water supply further inside your home, where temperatures are warmer.

How Frost-Free Hose Bibs Work: The valve controlling water flow is positioned inside the home, minimizing exposure to freezing temperatures.

Installation Benefits: Frost-free bibs enhance freeze protection and reduce the need for insulation or faucet covers.

If you’re considering this upgrade, a professional plumber can ensure proper installation for optimal performance.
