When Should I Let My Faucets Drip?

As cold weather swirls into your area, it’s a good idea to allow a few of your faucets to drip. During the winter months, when temperatures are around 20 degrees Fahrenheit or lower, water pipes throughout your home may be susceptible to temperatures well below freezing.

Pipes installed in outdoor areas or spaces that mimic the outdoor temperatures (like your garage) are especially at risk of freezing.

When pipes freeze, water cannot flow through them, thus restricting your ability to take a shower or wash clothes and dishes. On top of the inconveniences that accompany a lack of water, frozen pipes are prone to bursting.

When Should I Let My Faucets Drip

Since water freezes as it expands, the pipes may not be able to handle the additional pressure. Burst pipes can lead to a many issues, such as flooding, which will present related problems as well as water damage affecting your home.

 You can encourage movement through the pipes by allowing your faucets to drip when the temperature drops to sub-freezing levels. Although a few drops of water don’t seem like a lot, the minute movement caused by dripping pipes helps prevent them from freezing.

Do I Need To Let All My Faucets Drip?

To determine which faucets you should leave dripping, consider the location of the pipes connected to the faucet. You don’t necessarily need to leave all of your faucets dripping during cold weather.

For example, if a pipe branches directly from the hot water tank to a sink, you probably don’t need to drip this sink, as it isn’t exposed to cold weather. Now, let’s say you have a pipe that runs around the perimeter of your house and is directly exposed to the cold. You should allow the faucet correlated to this pipe to drip.

With that said, it is usually best to drip the faucet that is furthest away from the origin of the pipe. If you were to drip a single faucet along the pipe, especially those located closer to the pipe’s origin, the following sections of pipes and connected faucets could still potentially freeze.

So, by dripping a faucet that is furthest away from the water source, you will ensure that water moves throughout the entire pipe from one end to another.

How Much Does It Cost To Allow A Faucet To Drip?

Although water costs vary based on location, dripping a faucet usually doesn’t cost much. If you live in an area where water costs are high, you’ll run into higher costs than someone who lives in an area where water costs are low or cost-free.

On average, leaky faucets cost an average of $20 per year. If you allow your faucets to drip for the three coldest months of the year, then it’ll cost you even less, about $5 per year. These estimates are based on a faucet with a severe faucet leak, so chances are your leaky faucet will cost you even less.

Additionally, considering that allowing your faucet to drip is helping to prevent bursting pipes and a flooded home, the costs are pitiful in comparison. The national average for burst pipe repair sits at about $500. And that estimate is on pipes requiring moderate repair. If the damage is substantial, you could be facing repair costs of up to $2,000.

Should I Drip The Cold Water Faucet Only?

You may be wondering what temperature you should drip the faucets at. Contrary to popular belief, both cold water and hot water pipes are highly susceptible to freezing. Cold water pipes need to be dripped, but so do the hot water pipes. In sub-zero temperatures, hot water pipes cool down rapidly and are at substantial risk of freezing.

At night, the temperature typically drops, even more, increasing the chances of freezing. So, allow both the cold water faucet and the hot water faucet to drip slightly, thus preventing freezing of cold and hot water pipes. If you choose to drip one or the other, you run the risk of the other freezing.

Outdoor faucets also need to be dripped in addition to your indoor faucets. Outdoor spigots, like those you connect your garden hose to, and faucets are at a high risk of freezing, given their direct exposure to cold temperatures, so remember to allow them to drip.

Faucets located outdoors tend to connect to pipes running along the outside of your home, which means they are exposed to much chillier temperatures than your interior faucets. For this reason, it is imperative to allow your outdoor faucets to drip, too, especially considering many of them are fed by pipes from inside your home.
