You may be thinking, why does a dripping faucet prevent frozen pipes?

Its answer is simple. Dripping the faucet slows down the process of freezing and keeps the pressure inside the pipe down. Water freezes when its heat is transferred to cold air. If you can keep the faucet in a heated place, its heat won’t transfer into cold air.

But it is not possible. A house has many faucets and keeping them hot is not possible. It will cost a huge bill.

So dripping the faucet is a good solution.

When you let the faucet drip, its water remains in liquid form and flows through the whole pipeline. The temperature inside pipes doesn’t reach freezing point due to flowing water.

The constant flow of water will relieve pressure inside pipes. It won’t create any ice blockage. As the pipe won’t freeze, no burst will occur.
