How to "Winterize" Your Home and Commercial Building Plumbing Before Holiday Break

November 28, 2024

As the holiday season approaches, it’s easy to get caught up in festive plans and forget about practical matters—like protecting your plumbing from cold-weather mishaps. Failing to properly winterize your plumbing can lead to frozen pipes, leaks, and expensive repairs, which no one wants to deal with during or after the holidays. Whether you’re preparing your home or a commercial building, taking a few key steps now can save you a lot of trouble later. Here’s how to ensure your plumbing stays safe and sound during the winter break.


1. Inspect and Protect Pipes

Before temperatures drop, take a walk around your property to identify exposed pipes, especially those in unheated areas like basements, crawl spaces, or exterior walls.


  • For Homes: Wrap these pipes with foam insulation or heat tape to keep them warm.
  • For Commercial Buildings: Consider adding pipe insulation to larger systems, particularly in areas prone to freezing, like outdoor or rooftop piping.


2. Drain and Shut Off Outdoor Fixtures

Outdoor faucets and irrigation systems are particularly vulnerable to freezing temperatures.


  • Homes: Disconnect garden hoses and use an outdoor faucet cover. If your faucets have a shut-off valve inside the house, turn it off and drain the water from the pipe.
  • Commercial Properties: Drain all outdoor fixtures and any water features, like fountains, and winterize irrigation systems by blowing out the lines with compressed air.


3. Maintain Indoor Temperatures

Maintaining a consistent indoor temperature is one of the easiest ways to prevent frozen pipes.


  • For Homes: Set your thermostat to at least 60°F, even if you’re traveling. Open cabinet doors under sinks to allow warm air to circulate around the pipes.
  • For Commercial Buildings: Ensure your HVAC system is set to maintain a minimum temperature, especially in areas with water lines. Consider installing temperature monitoring systems to alert you to any sudden drops.


4. Inspect Water Heaters

A malfunctioning water heater is bad news in the winter. Inspect your water heater for signs of rust or leaks, and flush it to remove sediment buildup.


  • For Homes and Businesses: Consider scheduling a professional maintenance check to ensure the heater is operating efficiently.


5. Check for Leaks

Leaks, no matter how small, can worsen in freezing weather and lead to major issues. That’s why you need leak detection.



  • For Homes: Inspect faucets, toilets, and under-sink plumbing for any drips or puddles.
  • For Commercial Properties: Conduct a more comprehensive inspection of the building’s plumbing system or hire a professional to do so.


6. Shut Off the Water

If you plan to leave your home or business unattended during the holidays, shutting off the water supply can provide peace of mind.


  • Homes: After shutting off the main valve, open all faucets and flush toilets to drain the system.
  • Commercial Buildings: Work with your maintenance team or a plumber to safely shut down and drain the system while keeping fire protection systems operational.


7. Know the Emergency Shut-Off Valve

Despite your best efforts, accidents happen. Make sure everyone in your household or building knows where the main water shut-off valve is located. If a pipe bursts, turning it off quickly can minimize damage.


Schedule a Service With Plumb Works

When we think about spring cleaning our home, images like decluttering the garage or washing windows often come to mind. However, spring cleaning our home water quality isn’t always top of mind. Yet the time is certainly right.

Being proactive remains a key element of a successful business, and it certainly holds true when preparing for the possible devastating effects of stormy season. Spring remains one of the Atlanta area’s rainiest times of the year. According to Weather Spark, the average monthly rainfall from March through May ranges from 3 to 4.6 inches. Heavy spring storms can rain hard on a commercial facility. If unprepared, it can potentially lead to serious problems, causing everything from business downtime to costly repercussions. The following are several heavy rain-related issues that can cast a dark cloud on a commercial building and how to avoid them. Sump Pump: Fighting the Flood When it comes to flooding, stormwater remains a dreaded culprit. Having a properly functioning sump pump can help proactively help fight a flood. A sump pump collects groundwater from around a building’s foundation and pumps it away from the structure, deterring damage. Plumb Works suggests all businesses have one, especially those with a crawlspace or basement. Consult the experts at Plumb Works for sump pump installation, replacement, and preventative maintenance. Protection from Sewer Backups Heavy rains can overload a city’s sewer system. Backwater valves, a specific type of backflow prevention device, protect businesses from sewer backups by allowing wastewater out, but automatically closing to keep sewage from flowing backward. Plumb Works can install, test, and make sure your backwater valve is working properly. The Importance of Storm Drains Commercial storm drains are equipped to drain excess rain and groundwater from the areas surrounding a business, such as parking lots and sidewalks, preventing flooding, damages, and unsafe conditions. Some storm drain systems include a catch basin, which captures stormwater and separates any debris that may have come along with it. Having Plumb Works inspect, clean, and repair storm drains and catch basins can help businesses avoid a flood of unwanted costs. Cutting Out Grease Commercial kitchens require a grease trap, which keeps the plumbing system from being impacted by an overload of grease. If a grease trap isn’t functioning properly, it can have an adverse effect on a plumbing system during heavy rain. Too much grease limits pipe capacity, which can cause heavy rain to overwhelm a system, leading to backups. To avoid this, consult a plumbing professional company like Plumb Works that specializes in grease trap services. Avoiding Clogged Drains Plumbing systems in commercial facilities often fall prey to clogged pipes due to unwanted items being flushed or disposed of down drains. This can further complicate things when a mass amount of rain overwhelms a plumbing system. Businesses experiencing frequent clogs can benefit from hydro jetting. The most effective drain-cleaning solution available, hydro jetting uses high-pressure water jets to blast through clogged drains and restore peak plumbing performance. Schedule hydro jetting in advance of the rainy season to make sure pipes are functioning at their best under any possible pressure.

Nothing puts the cold chill on the festive holiday season like a frozen or burst pipe. Frozen pipes are bad enough, but when they burst, the problem worsens and can easily lead to flood damage requiring costly repairs. This all-too-common occurrence affects an estimated 250,000 homes in America each year. And Georgia may be a hot bed for frozen pipes. According to a State Farm report released in 2023, Georgia topped the list of frozen pipe-related losses at $100 million (from August 2002-August 2023.) Plumb Works remains your go-to source for frozen or burst pipe calls in our service area. However, there are some simple tips you can apply to protect pipes in cold weather and help avoid a house call. Before the thermometer dips below freezing – that’s 32 degrees Fahrenheit – do the following:
