As the owner and operator of a local pipes and fittings supply company, I\u2019ve spent more winters than I can count talking to homeowners, contractors, and small business owners who\u2019ve had the same panic-inducing conversation: \u201cMy pipes burst last night\u2014can you send someone to fix this, and do you have anything to help me make sure it never happens again?\u201d Pipes and Fittings<\/a><\/p>\n

<\/p>\n

If you\u2019ve lived in a place where winter temperatures drop below freezing (and stay there for weeks on end), this isn\u2019t just a hypothetical. Burst pipes don\u2019t just ruin your plumbing\u2014they flood walls, warp floors, damage personal belongings, and run up thousands of dollars in repair bills. Last year alone, we supplied replacement fittings to 12 local families who\u2019d dealt with frozen and burst pipes, and every single one told us they wish they\u2019d known the simple, science-backed steps to prevent this before the cold set in.<\/p>\n

Today, I\u2019m sharing the practical, fact-based tips we\u2019ve seen work time and again, tailored to work with the pipes and fittings we supply for residential, commercial, and even small-scale construction projects. Let\u2019s start with the basics that too many people skip, because understanding why freezing causes damage is the key to stopping it.<\/p>\n

The Science Behind Frozen Pipe Damage (And Why Your Fittings Matter)<\/h3>\n

When water turns to ice, it expands by roughly 9%\u2014that\u2019s a physical rule, not a myth. But it\u2019s not just the ice itself that causes breaks. Here\u2019s what happens: water flows through pipes at a relatively constant pressure. When a section of the pipe (or a fitting) freezes, that section becomes a blockage. The still water behind that blockage keeps expanding, creating pressure that builds until it has nowhere to go. That pressure can crack the pipe itself, or split a fitting at the joints\u2014especially if that fitting is old, made of low-quality materials, or installed incorrectly.<\/p>\n

This is where the quality of the pipes and fittings you use makes a huge difference. A cheap, thin plastic supply line might crack under that 1,500+ PSI of ice pressure, but a durable, cross-linked polyethylene (PEX) pipe or a properly installed brass fitting can flex slightly to accommodate that expansion without breaking. Last winter, one of our regular contractors installed our commercial-grade PEX lines with the matching brass compression fittings for a new walk-in cooler, and even when temperatures dropped to 12 degrees Fahrenheit, they had no issues\u2014while three nearby buildings with standard PVC pipes and fittings had burst within 48 hours. That\u2019s not luck\u2014it\u2019s using the right components for the job.<\/p>\n

Now, let\u2019s get into the actionable steps you can take, organized by which part of your plumbing system you\u2019re addressing.<\/p>\n

Insulate: The Single Most Effective Step We Recommend<\/h3>\n

Insulation isn\u2019t just for keeping your home warm\u2014it\u2019s the first line of defense against frozen pipes. The goal here is to maintain the temperature of the water inside the pipe above 32\u00b0F, even when outside temperatures are way lower. Not all insulation is the same, and using the right one paired with the right fittings makes this even more effective.<\/p>\n

First, target the areas of your home that are most exposed to cold: exterior walls, basements, attics, crawl spaces, and any pipes that run along unheated floors or ceilings. For pipes in these spaces, we supply two main types of insulation that work best for our customers: foam pipe insulation sleeves and fiberglass wrap.<\/p>\n

Foam insulation sleeves are the easiest to install\u2014they slip right over most standard \u00bd-inch or \u00be-inch pipes, and come with a slit down the side so you don\u2019t have to cut them to fit. For joints, elbows, and T-fittings, we sell pre-cut insulating tape or small foam fitting covers that wrap around the curved, harder-to-inspect areas. This is key because most people forget that fittings are just as vulnerable as straight pipe\u2014an uninsulated elbow in an unheated crawl space is just as likely to freeze as a straight run of pipe.<\/p>\n

For areas that are extra cold, like unheated garages or exterior wall cavities, adding an extra layer of insulation (or even a heat trace cable) paired with our UV-resistant foam insulation for outdoor pipes works even better. I always tell customers: if you can see a pipe that runs along an outside wall, it needs insulation. Last month, a homeowner came in saying their garage sink pipe froze every year\u2014after we explained that their pipe was bare right against the outside wall, we supplied insulation sleeves and a small heat trace kit, and they haven\u2019t had a problem since.<\/p>\n

One common mistake people make here is using the wrong insulation. For example, don\u2019t use standard household insulation (like fiberglass attic batts) around small pipes\u2014they won\u2019t seal the air gaps that let cold in, and they can leave parts of the pipe exposed. Stick to pipe-specific insulation, which is designed to fit tightly and cover every inch of the pipe and its fittings.<\/p>\n

Seal Air Leaks: Block Cold Air Where It Gets In<\/h3>\n

Even if your pipes are insulated, cold air leaking into your walls, floors, or crawl spaces can find its way to your pipes and cause them to freeze. Sealing these gaps is a quick, low-cost step that we recommend to every customer.<\/p>\n

Start by checking areas where pipes penetrate your home: where they come through exterior walls, foundation walls, or crawl space access points. Use silicone caulk or expanding foam (but make sure it\u2019s the low-expanding kind\u2014too much foam can shift or damage pipes) to seal any gaps around pipe fittings, pipe penetrations, and the gaps between your home\u2019s frame and exterior walls.<\/p>\n

I always advise homeowners to check their attic hatches and crawl space doors too\u2014if these areas are drafty, they\u2019ll let cold air seep down to pipes in the ceiling or floor. Adding weatherstripping to these doors and hatches is a simple fix, and it also helps lower your heating bills, so it\u2019s a win-win.<\/p>\n

For older homes, pay extra attention to floor joists in the basement or crawl space. Sometimes, a gap under a subfloor can let cold air rise directly to the pipes running between joists. We often supply lightweight, sprayable foam sealant for these tight gaps, since it\u2019s easy to apply and lasts for multiple winters.<\/p>\n

Keep Water Flowing: Stagnant Water Freezes Faster Than Moving Water<\/h3>\n

This is a tip that\u2019s so simple, it\u2019s often overlooked. Moving water doesn\u2019t freeze as easily as still water\u2014so keeping a small trickle of water running through your pipes when temperatures dip below freezing can prevent ice buildup, even if your heat goes out for a few hours.<\/p>\n

But here\u2019s the right way to do this (so you don\u2019t waste water or cause water damage): you only need a tiny flow\u2014not a full stream. For exposed pipes, leave both hot and cold water taps dripping just enough that you can hear a steady, soft drip. This keeps the water in the pipe moving, so it doesn\u2019t have time to freeze solid.<\/p>\n

Wait, but what about pipes that aren\u2019t exposed? If you have pipes in an unheated attic or crawl space, a dripping tap can still help, but we also recommend checking if those pipes have any valves or shutoff points that can be adjusted to keep a slight flow. Another trick: open cabinet doors under sinks that are on exterior walls. Letting warm air from your home circulate around those pipes and their fittings keeps them above freezing, even if the cabinet is right next to an outside wall.<\/p>\n

One note about this tip: it works best for short periods of extreme cold (24 to 48 hours). If you\u2019re going to be away from home for an extended period in freezing weather, don\u2019t just leave a tap dripping\u2014follow our next step for emptying unused pipes.<\/p>\n

Drain and Disconnect Outdoor Pipes: Don\u2019t Forget Exterior Faucets<\/h3>\n

Outdoor spigots, hose bibs, and the pipes that connect them are some of the most common points of frozen pipe damage we see every winter. These are exposed to wind and cold directly, so they freeze faster than indoor pipes, and the fittings here are often installed with old, low-quality parts that can\u2019t handle expansion.<\/p>\n

The process here is simple, but it has to be done correctly. First, turn off the water supply to your outdoor spigot from inside your home (usually there\u2019s a shutoff valve located in your basement, crawl space, or utility room). Then, open the outdoor faucet fully to drain any remaining water from the pipe. Most hose bibs have a small drain plug at the base\u2014take that off to let any leftover water escape, then store your garden hose indoors.<\/p>\n

If you have an outdoor hose that runs to a garage or shed, disconnect that hose before temperatures drop to freezing. Even if the hose isn\u2019t connected, water can sit in the fitting at the spigot and freeze. We supply frost-free hose bibs as a long-term upgrade too\u2014these are designed to keep the shutoff valve inside your home, so the pipe from the house to the spigot never gets exposed to cold, drastically reducing the risk of freezing.<\/p>\n

Maintain a Consistent Indoor Temperature: Even When You\u2019re Away<\/h3>\n

Leaving your home at a consistent temperature, even if you\u2019re at work or on vacation, is a simple way to prevent frozen pipes. I know it\u2019s tempting to turn the thermostat down to save energy when you\u2019re gone, but setting it to at least 55\u00b0F will keep the air inside your home warm enough that the pipes won\u2019t freeze. For extra assurance, some of our customers install smart thermostats that let them adjust temperatures remotely, or pipe thermometers that send an alert if a pipe\u2019s temperature drops too low.<\/p>\n

If you do have to leave for an extended period (like a winter vacation in a warm place), make sure to turn off the main water supply and drain all the pipes. This is especially important for vacation homes, which often sit empty for weeks at a time. We supply the necessary tools for this\u2014pipe wrenches to shut off the main valve, and small pump kits to blow out any remaining water from the lines, including the fittings. Last year, a customer who owns a cabin came to us in October, told us he\u2019d had a pipe burst there two years prior, and we walked him through draining the lines, and supplied a few extra insulation sleeves for the main water line. He didn\u2019t have a single issue all winter.<\/p>\n

When It Comes to Fittings, Quality Beats Cost<\/h3>\n

Throughout all these tips, I can\u2019t stress enough how important it is to use high-quality pipes and fittings for your plumbing system. Cheap PVC pipes can crack under pressure from expanding ice, and low-quality plastic fittings can split at the joints, even with insulation. Our company focuses on supplying durable, code-compliant PEX pipes, brass compression fittings, and copper pipes that are designed to handle temperature extremes, and we stand behind every product we sell.<\/p>\n

For example, brass fittings are far more resistant to cracking from ice expansion than PVC or even some thin plastic fittings. When you connect a PEX line to a brass fitting, that combination flexes just enough to absorb the 9% expansion of ice, without breaking. We\u2019ve seen this time and again: contractors who use our brass fittings and PEX lines report zero frozen pipe-related calls during the winter, while those who use generic fittings have 2 or 3 issues per project.<\/p>\n

Another thing: always make sure fittings are installed correctly. Even the best fitting will fail if it\u2019s not seated properly or tightened with the right tools. We offer free installation tips for every product we sell, and our team is always available to walk you through how to connect a new fitting or pipe, so you don\u2019t make a mistake that could lead to a freeze.<\/p>\n

What To Do If You Do Have a Frozen Pipe (And How We Can Help)<\/h3>\n

Even with all these steps, sometimes a pipe will freeze. If you notice a leak, frost on a pipe, or no water coming from a tap, turn off the main water supply immediately to prevent bursting, then apply gentle heat to the frozen section. Use a hair dryer, space heater, or heating pad (never an open flame or a blowtorch\u2014this can melt pipes and start fires). Once the ice thaws, check for leaks, and if you find one, call a plumber. If you need replacement pipes or fittings, we have same-day pickup and local delivery for emergency orders, so you can get your home back to normal quickly.<\/p>\n
