You may wonder why the water pipe suddenly burst, but the main causes are freezing, aging and earthquake.The following sections describe each cause.
When living in a cold area or experiencing a sudden drop in temperature (cold wave), an outdoor pipe burst due to freezing.The volume of water increases when it freezes, so the water pipe may burst due to pressure from the inside.Basically, measures such as winding a heat insulating tube or insulating material around the water pipe can prevent rupture due to freezing, but depending on the location of the pipe and weather, temperature may drop more than expected and freeze.
You need to be careful about piping in places where it is easy to shade or get wind even during the day.It is said that water pipe rupture is likely to occur if it falls below minus 4 degrees Celsius.To prevent freezing, it is better to keep the water in the water pipe flowing little by little.
deterioration over time
Other than freezing, water pipes may burst and overflow.In particular, many reasons are caused by aging.Generally, water pipes have a lifespan of 10 to 15 years.Water pipes are constantly under pressure, so they deteriorate little by little over time, eventually causing cracks and rusts to burst.
The strength of water pipes varies depending on the thickness and material, and the useful life varies depending on how you use water and the environment, so 10 to 15 years is a guideline.Depending on the external environment, defects such as rupture may occur even if it is less than 10 years old.
A strong impact is applied to the water pipe by an earthquake, which can cause rupture due to cracks and deformation.If cracks or deformations occur, even small tremors and vibrations will cause great damage to the water pipes, so let’s check if there are any cracks or deformations in the water pipes after an earthquake.Water pipes buried in walls and underground cannot be visually checked, so please check if the water meter is running without using water to see if there is a leak.
the symptoms or damage caused by a burst water pipe
The water pipes are not always in a visible location.Most of them are buried in walls or underground, so you have to predict the rupture indirectly.Since the points of determination are different between indoor and outdoor, I will explain each symptom.
