Ice Ice Baby! How To Prevent Your Pipes From Freezing This Winter

How to Prevent Your Pipes From Freezing This Winter

A faucet that barely runs on a freezing morning may be warning you about ice inside a water line. If that pipe splits, the damage can remain hidden until it thaws and water starts leaking into walls, ceilings, or your basement.

Preparing your plumbing before freezing weather arrives helps reduce that risk. For homeowners in Northbrook, IL, that means protecting exposed pipes, draining outdoor faucets, and making sure indoor plumbing stays warm throughout winter.

Bill’s Plumbing and Sewer provides residential and commercial plumbing services in Northbrook. Here are the steps to take before the next cold spell—and the problems that call for a plumber.

Start With the Pipes Most Exposed to Cold

Water expands as it freezes, creating pressure that can damage pipes and fittings. Both metal and plastic water lines can be affected.

Walk through your home and look for plumbing in areas that receive little heat:

  • Unfinished basements and crawl spaces.
  • Attics and attached garages.
  • Kitchen and bathroom cabinets along exterior walls.
  • Outdoor faucets and the water lines supplying them.
  • Areas where cold drafts enter around pipe openings.

A pipe that has frozen before deserves attention before temperatures drop again. Insulation may help, but recurring freezing can also point to air leaks, inadequate heat, or a poorly protected pipe location.

Disconnect Garden Hoses and Winterize Your Hose Bibs

A hose bib is the outdoor faucet where you connect a garden hose. Leaving a hose attached can trap water and prevent the faucet from draining. That trapped water can freeze and damage the faucet or piping inside the wall.

Disconnect hoses before the first freeze, even if your outdoor faucets are labeled frost-free.

Shut Off and Drain a Standard Outdoor Faucet

For a conventional hose bib with a separate indoor shutoff valve, follow these steps:

  1. Turn off the outdoor faucet. Disconnect the garden hose and removable watering accessories, such as timers and splitters. Drain the hose and store it for winter.
  2. Locate the indoor valve supplying that faucet. It is often in the basement or crawl space near where the pipe passes through the exterior wall.
  3. Close the supply valve. A typical round handle turns clockwise to close; a standard quarter-turn valve closes when its lever is perpendicular to the pipe. Do not force a stuck or corroded valve.
  4. Return outside and open the hose bib to drain the remaining water. Once drained, leave this conventional faucet open for winter while its indoor supply valve stays closed.
  5. If the indoor valve has a drain or bleeder port, follow its instructions to drain trapped water. Ask a plumber for help if you are unsure how it operates.

Water that continues flowing after the line should have drained may mean the indoor shutoff is not closing fully. Have it checked rather than assuming the faucet is protected. An insulated outdoor faucet cover can provide additional protection, but it does not replace proper draining.

Protect Frost-Free Outdoor Faucets, Too

A frost-free hose bib shuts off water farther inside the building and is designed to drain when correctly installed. For these models, disconnect the hose, close the outdoor faucet, and allow it to drain according to the manufacturer’s instructions. Do not leave a supplied frost-free faucet open for winter.

Frost-free does not mean freeze-proof under every condition. A connected hose, an incorrect installation angle, or an unheated space around the supply piping can still cause trouble. If you cannot identify your faucet type or find its shutoff, have a plumber check the setup.

Keep the Heating Consistent

Keep your heating on during freezing weather, including when you leave town. The American Red Cross recommends a thermostat setting no lower than 55°F while you are away. Pipes in cold wall cavities or drafty areas may need additional protection even at that setting.

During severe cold, avoid large nighttime temperature setbacks. If your furnace struggles to maintain the indoor temperature, arrange heating repair in Northbrook, IL before leaving your home unattended.

Let Warm Air Reach Indoor Plumbing

Open kitchen and bathroom cabinet doors during very cold weather so room heat can reach pipes underneath sinks. Move cleaning products out of reach of children and pets.

Keep the garage door closed if water lines run through the garage. Keep the door between the house and attached garage closed as well; garage plumbing needs its own appropriate freeze protection.

Add Pipe Insulation and Seal Drafts

Fit suitable pipe insulation around exposed hot and cold water lines in unheated areas. Cover vulnerable sections consistently, including bends and fittings where the insulation system allows.

Insulation slows heat loss; it does not generate heat. A pipe exposed to prolonged freezing conditions can still freeze.

Check for drafts around plumbing penetrations, basement windows, and exterior-wall openings. Seal appropriate gaps with materials suited to the location. Keep required ventilation openings and appliance vents clear.

Use Heating Cable Only as Directed

Pipe-heating cable may help protect accessible water lines that remain vulnerable to freezing. Choose a listed product approved for your pipe material and installation location.

Follow the manufacturer’s directions for installation, electrical protection, insulation, and operation. Do not overlap cable unless the instructions specifically allow it, and replace damaged products. A plumber can help assess whether heating cable or a change to the piping is the better solution.

Let an At-Risk Indoor Faucet Drip During Severe Cold

A small flow through a vulnerable indoor water line can help reduce freezing risk. Use the faucet served by that line; dripping an unrelated faucet may not protect it. Hot and cold supply lines may both need consideration.

Keep the drain clear and ask your plumber which fixtures to use if you are unsure. Dripping is a temporary precaution, not a substitute for correcting recurring freezing problems.

Act Quickly if You Suspect a Frozen Pipe

Little or no water from one faucet during freezing weather can indicate a frozen supply line, particularly when other fixtures still work. Frost on exposed piping, unusual bulges, or damp walls also need attention.

If you find a leak or suspect a burst pipe, close the main water shutoff if you can reach it safely and call a plumber. Stay away from standing water near electrical equipment.

Never use a torch or open flame to thaw plumbing. If the frozen section is hidden, damaged, or inaccessible, leave the thawing and inspection to a professional. Restored water flow does not necessarily mean the pipe escaped damage.

Clogged drain from baby wipes in Cook County, IL.

Can Baby Wipes Clog Your Toilet or Sewer Line?

Baby wipes are convenient for cleaning up messes, but they can create serious plumbing problems when they are flushed down the toilet. Even wipes labeled as “flushable” can contribute to clogged drains, blocked toilets, and sewer line issues over time. Many homeowners assume wipes break down the same way toilet paper does. The reality is that most wipes are designed to stay strong and durable when wet, which means they may not break apart quickly enough as they travel through your plumbing system. For homeowners in Northbrook, IL, a buildup of wipes in your drain pipes or sewer line can lead to slow drains, backups, and costly repairs if the problem is not addressed early. Why Baby Wipes Cause Drain and Sewer Problems Most baby wipes are made from synthetic fibers such as polyester or polypropylene, blended with materials like cotton or plant-based fibers. These materials are designed to hold together when wet, making wipes effective for cleaning but difficult for plumbing systems to process. Unlike toilet paper, which is specifically designed to dissolve quickly after flushing, wipes can remain intact as they move through your pipes. When multiple wipes collect in the plumbing system, they can catch on pipe buildup, combine with grease or debris, and create a blockage. A drain pipe clogged by wipes can cause: Slow-draining sinks or tubs Toilets that frequently back up Water coming back up through drains Sewer odors Complete sewer line blockages Are Flushable Wipes Safe for Your Plumbing? Some wipes are marketed as flushable, but that does not always mean they will move safely through every plumbing system. Testing standards and real-world plumbing conditions can vary. Older sewer lines, pipes with buildup, and homes with existing drainage issues may be more likely to experience problems when wipes are flushed regularly. The safest option for your plumbing is to dispose of wipes in the trash, even if the packaging says they are flushable. What About Water Wipes? Are They Flushable? Water-based wipes, including brands such as WaterWipes, are designed with sensitive skin in mind and may contain fewer additives than traditional wipes. However, being gentle on skin does not mean they are designed to break down like toilet paper. Like other wipes, they can contribute to plumbing problems when flushed repeatedly. If you want to protect your drains and sewer line, avoid flushing wipes of any kind. How to Remove Baby Wipes From a Toilet or Drain If wipes are already causing a blockage, using chemical drain cleaners is usually not the best solution. Many drain cleaners are designed for dissolving organic buildup but will not break down durable wipe materials. Depending on where the blockage is located, solutions may include: Using a toilet auger to remove wipes near the toilet Removing visible buildup manually when accessible Using professional drain equipment for deeper blockages Performing a sewer line inspection if backups continue When wipes move deeper into the plumbing system, they can become difficult to remove without professional tools. Signs Baby Wipes May Be Blocking Your Sewer Line A few wipes flushed accidentally may not cause an immediate problem. Issues usually develop when wipes accumulate over time. Watch for these warning signs: Toilets that clog repeatedly Multiple slow drains throughout your home Gurgling sounds from pipes Water backing up into tubs or sinks Sewage odors near drains These symptoms may indicate a larger issue with your sewer line rather than a simple toilet clog.

Our team can help identify the cause of recurring clogs and determine the right solution, whether the issue is located in a toilet, drain pipe, or sewer line.

sewer pipe hydro jetting in Northbrook, IL

Hydro Jetting in Northbrook, IL: A Powerful Solution for Stubborn Sewer Line Clogs

When traditional drain cleaning methods are not enough, hydro jetting can provide a deeper clean for your plumbing system. At Bill’s Plumbing and Sewer in Northbrook, IL, hydro jet drain cleaning is used to remove tough buildup, grease, debris, and other blockages that can restrict your sewer line. Unlike basic drain snaking, which typically creates a path through a clog, hydro jet plumbing uses high-pressure water to clean the inside walls of your pipes. This helps restore better flow and can help prevent recurring sewer problems. What Is Hydro Jetting? Hydro jetting is a professional drain cleaning method that uses highly pressurized water to clear and clean plumbing pipes. A specialized nozzle is inserted into the sewer line, where powerful streams of water break apart buildup and flush debris out of the system. Hydro jet sewer cleaning can remove: Grease and sludge buildup Soap residue Mineral deposits Tree root intrusion Food waste and debris Other materials restricting water flow For homeowners dealing with recurring clogs, slow drains, or sewer backups, hydro jetting sewer line services can provide a more complete cleaning than standard drain clearing methods. How Hydro Jetting Works The process begins with an inspection of the sewer line to determine the condition of the pipes. At Bill’s Plumbing and Sewer, camera inspections are used to look inside the sewer line and identify the cause of the problem before recommending a solution. A small waterproof camera is guided through the plumbing system, allowing technicians to locate: Blockages inside the pipe Cracks or damage Tree roots growing into the line Areas with heavy buildup Once the problem is identified, hydro jet equipment can be used to target the buildup and clean the pipe walls. The high-pressure water moves through the line, breaking apart debris and flushing it away. This combination of sewer camera inspection and hydro jetting allows for a more accurate diagnosis and a more effective plumbing solution. When Is Hydro Jet Drain Cleaning Needed? Hydro jet drain cleaning is commonly recommended when homeowners experience: Frequent sewer line clogs Slow drains throughout the home Recurring backups Gurgling pipes or toilets Foul sewer odors Heavy grease or sludge buildup If a drain keeps clogging after traditional cleaning methods, there may be buildup inside the pipe that needs more than a temporary fix. Hydro jetting helps remove the material causing the restriction instead of simply opening a small passage through it. Is Hydro Jetting Worth It? For many homeowners, hydro jetting is worth considering because it provides a deeper sewer cleaning than standard drain services. Instead of only removing the immediate blockage, hydro jet sewer cleaning helps clear buildup along the inside of the pipe. The benefits of hydro jetting include: More thorough pipe cleaning Improved water flow Longer-lasting results Reduced risk of recurring clogs Better understanding of sewer line conditions through camera inspection However, hydro jetting is not the right solution for every plumbing issue. Severely damaged or fragile pipes may require repairs or replacement instead. A sewer camera inspection helps determine whether your plumbing system can safely benefit from hydro jetting. How Much Does Hydro Jetting Cost? The cost of hydro jetting depends on several factors, including the location of the blockage, the condition of the sewer line, the severity of the buildup, and whether a camera inspection is needed. Because every plumbing system is different, an accurate estimate requires evaluating the condition of the pipes first. Bill’s Plumbing and Sewer uses professional inspection methods to determine the best approach for each home.
