How to Prevent Frozen Pipes in Colorado Winters

Frozen pipes are not only a cold-weather inconvenience. When water freezes inside a vulnerable section of pipe, pressure can build and damage the plumbing. The problem may not become obvious until the pipe thaws and begins leaking. Preparing before a strong Northern Colorado cold snap is much easier than dealing with water damage afterward.

Which pipes are most likely to freeze?

Plumbing is most vulnerable where cold outdoor air can reach it. Common areas include crawl spaces, unfinished basements, garages, exterior walls, utility rooms, cabinets against outside walls, and outdoor faucet supply lines. Homes with past additions or remodeled spaces may also have plumbing running through areas with less insulation than the original structure.

Find vulnerable plumbing before temperatures drop

Walk through the home and identify where water lines enter exterior walls or travel through unheated spaces. Look under sinks, around utility areas, in crawl spaces, and near hose bibs. You do not need to expose hidden plumbing. The goal is simply to know which parts of the system are most likely to be affected during a freeze.

Insulate accessible exposed pipes

Pipe insulation can provide added protection where plumbing passes through colder areas. Choose insulation that fits the pipe size and location. Pay attention to nearby air gaps as well. A well-insulated pipe can still freeze if extremely cold outside air is blowing directly across it through an unsealed opening.

Disconnect garden hoses

A connected garden hose can trap water at an outdoor faucet and increase freeze risk. Disconnect hoses before freezing weather arrives. Depending on the home's plumbing design, you may also have an interior shutoff for the outdoor line. If you are not sure whether your faucet is frost-resistant, ask a plumber to identify the setup.

Keep the home heated consistently

Avoid major indoor temperature drops during very cold weather. Rooms containing plumbing should receive enough heat to remain above freezing. If you are leaving town, do not shut the heating system off completely. A prolonged cold period can affect areas that normally stay warm enough during shorter freezes.

Open cabinets when plumbing is against an exterior wall

Opening sink cabinet doors can help room air reach plumbing that sits against a cold exterior wall. This is especially useful in kitchens and bathrooms where cabinet doors normally block warm airflow. Make sure household chemicals or cleaning products remain safely out of reach if children or pets are present.

Know where your main water shutoff is

The time to locate the main shutoff is before a pipe fails. Make sure you know where it is and that household members can find it. If a pipe bursts, shutting off the water quickly can greatly reduce how much water reaches floors, walls, cabinets, and finished spaces.

What if a faucet suddenly stops flowing?

During freezing weather, little or no flow from one faucet can indicate a frozen section of pipe. Keep the faucet open and gently warm the surrounding area if the location is accessible and safe. Never use an open flame. If the frozen location is hidden, difficult to reach, or showing signs of leakage, call a plumber.

What to do if a pipe bursts

Shut off the main water supply as quickly as possible. If water is near electrical equipment, outlets, or wiring, avoid the area until it is safe. Open a faucet to relieve remaining pressure and call for plumbing service. Photos of the affected area can help explain the problem before the technician arrives.
