How Do You Keep Pipes from Freezing without Heat?

Table of Contents

Have you ever woken up to the daunting surprise of no running water on a chilly winter morning, only to realize the culprit is none other than frozen pipes? It’s a common issue that plagues many households when the mercury takes a nosedive, but fear not—there are preventative steps you can take to keep the flow going all season long even if you happen to lose heat. In this blog post, we’ll dive into the depths of why pipes freezing is more than just a cold-weather nuisance and how you can safeguard your home’s plumbing. Wrap up warm and get ready to learn the secrets to combating the freeze and keeping your water running as smoothly as a serene winter’s stream. Here are our top ways to prevent frozen pipes:

Insulate Your Pipes and Your Water Tanks

One of the most effective ways to protect your home from the costly damage of frozen pipes is to insulate them. This simple measure not only helps to prevent your pipes from freezing but also conserves energy by reducing heat loss from your hot water pipes. Pipes located in unheated spaces like basements, attics, garages, or even those that pass through exterior walls, are at the highest risk of freezing during the cold winter months. When water within these pipes freezes, it expands, which can cause the pipes to burst. Insulating them provides a layer of protection, delaying the freezing process and reducing the likelihood of a pipe burst.

Open Cabinet Doors and Upstairs Doors

As winter approaches and the thermostat dips, homeowners face the perennial challenge of keeping their pipes from freezing. Among the lesser-known yet highly effective strategies is the practice of opening cabinet doors and loft hatches. This may seem like a trivial action, but it serves a critical purpose in maintaining a consistent temperature throughout your home to safeguard your plumbing during cold snaps.

Cabinets can act as barriers between the warm air in your home and the pipes installed within or behind them. By simply opening these doors, you allow the heat to circulate more freely around the plumbing. For cabinets found under sinks—as these areas are often on outside walls of a house—the open doors can prevent the enclosed space from becoming significantly colder than the rest of the room. Be particularly mindful of cabinets in your kitchen and bathroom, as these often contain critical water pipes.

Similarly, due to heat rising, upstairs rooms can become a reservoir of warm air that rarely reaches the rest of your home. By opening the door,s you encourage warm air to drift into your attic where water tanks and pipes are often located. This can be particularly effective in houses where insulation is lacking or outdated, as it decreases the chance of cold pockets of air contributing to pipe freezing.

Run Your Taps

One practical step for pipe freeze protection is to run your taps at a trickle during extremely cold weather. Water has a unique property in that it expands as it freezes. This expansion puts pressure on whatever contains it, including metal or plastic pipes. When water inside your pipes begins to freeze, the pressure can cause the pipe to crack or even burst, leading to potential flooding and substantial water damage once the ice thaws. Running water through the pipes, even at a minimal flow rate, helps prevent freezing and relieves pressure.

Drain Your Water System

One highly effective method for preventing pipes freezing is to drain your water system, especially if you plan to be away from your home for an extended period during the winter months.

  • Step 1: Turn Off the Main Water SupplyBefore beginning the draining process, locate your main water shut-off valve and turn it off. This valve is often found in the basement, garage, or outdoors near the foundation. Turning off the main water supply prevents more water from entering the pipes as you drain them.
  • Step 2: Open All Faucets and ValvesStarting from the top floor of your house, open all faucets, including those on the outside of your home. Don’t forget to also open any valves, such as those on your washing machine, dishwasher, or ice maker. Opening these fixtures allows the water to flow out of the pipes.
  • Step 3: Flush the Toilets Flush all toilets in the house to drain the water from the tanks and the bowls. If necessary, hold the flush lever down to completely empty the tank.
  • Step 4: Drain the Water Heater – If you have a traditional tank-style water heater, turn off the power supply to it and attach a garden hose to the drain valve at the bottom of the tank. Open the drain valve and lead the other end of the hose to a location where it can safely drain, such as a basement drain or outdoors. Draining the water heater is crucial because the stagnant water inside can freeze and cause the tank to crack.
  • Step 5: Open the Low-Point Drain Valve – Your plumbing system may have a low-point drain valve expressly for draining purposes. Open it and allow any remaining water to drain out. Collect the water in a bucket or direct it to a suitable drain.


Of course, this can sound like an overwhelming process if you do not know where many of these things are located in your home. If you need an emergency plumber in Richmond, VA, call Plumber Near Me for help 24/7!

Use Heat Tape

Heat tape, also known as heat cable or heat trace, is an essential tool that can be used to ensure pipes remain above the freezing point. There are generally two types of heat tape: self-regulating and constant wattage. Self-regulating heat tape adjusts its output based on the surrounding temperature, which can be more energy-efficient. On the other hand, constant wattage heat tape provides a consistent amount of heat and may be less expensive upfront. Choose the right type based on your climate and specific needs.

Once you’ve selected the type of heat tape you want to use, find the pipes in your house that are most exposed to cold. Read the installation directions carefully to cut the correct length and place the tape at the specified spacing. After the tape has been applied, you can plug the tape into a GFCI plug for safety. It is important to keep an eye on the tape over time to look for signs of wear and tear.

Reduce Drafts

Reducing drafts is a crucial step in this process as drafts can lead to colder temperatures within areas of a building, especially where plumbing is present, thereby increasing the risk of pipes freezing. Common areas might include windows, doors, attics, basements, and even gaps in exterior walls. You can use weatherstripping, caulk, expanding foam, door sweeps, and insulation as effective measures to reduce airflow into the building. Additionally, consider maintenance on your windows and doors. By replacing broken glass, repairing damaged frames, adding window film, or considering the installation of double-glazed windows, you can decrease drafts and heat leaks.

What temperature should you keep your house in winter so the pipes don’t freeze?

If you are without heat this winter, you might wonder what the pipes freezing temperature is. Experts typically agree that maintaining an indoor temperature of at least 55 degrees Fahrenheit is essential during the winter months. This benchmark temperature is generally sufficient to keep the air within your home warm enough to prevent the water inside your pipes from freezing, especially in areas of your home where they may be exposed to external walls or inadequate insulation. Wondering what else you can do to help prevent plumbing issues? Check out our plumbing maintenance checklist!

How to wrap pipes for winter?

  1. Identify Vulnerable Pipes: First, identify which pipes are most at risk of freezing. These include pipes in unheated areas like basements, attics, garages, and exterior walls.
  2. Measure and Cut Your Insulation Material: Measure the length of the pipe you need to cover. Using the correct insulation material, such as foam pipe covers or fiberglass insulation, cut the required amount.
  3. Secure the Insulation: Open the pipe cover and place it around the pipe. For straight sections of pipe, tubes with pre-cut slits can easily be fitted. Use durable tape, wire, or cable ties to secure the insulation at regular intervals. Ensure there are no gaps where air can penetrate.
  4. Insulate the Pipe Fittings: For joints and bends, you might use specialized insulation such as elbow covers or miter the tube insulation to fit tightly around these complex shapes.
  5. Layer It Up: In severely cold areas, consider double-wrapping the pipes or using extra insulation wrap for an added layer of protection.

When picking a material, keep in mind that the best pipe insulation to prevent freezing will depend on your pipe material, average winter temperatures, and budget.

Does PVC pipe freeze?

The answer is nuanced. While PVC pipes do not freeze in the same way water does, they are still vulnerable to the effects of extreme cold. PVC, a widely used plastic for residential and commercial plumbing systems, is celebrated for its durability and ease of installation. However, it is susceptible to becoming brittle and can crack when exposed to freezing temperatures. This is because PVC, like most materials, contracts as the temperature decreases. If there is water inside the PVC pipe, and it freezes, the expansion of the ice can exert pressure on the pipe, potentially leading to cracks or bursts.
