There are many things that go into the process of fixing a blocked drain. This includes understanding what is causing the obstruction, assessing the damage and then coming up with a plan to fix it. A qualified drainage company in Oswestry will have all of this knowledge and more, so you can rest assured that your drains will be fixed quickly and properly. One common cause of blocked drains is human activity. If someone has put something down their sink that isn’t supposed to be there (like hair), water can get trapped and block the drain over time. In addition, if debris accumulates on top of the pipe over time, it can also become obstructive. Storms or heavy rainwater runoff are other causes of flooding due to clogged drains – when these torrential rains hit an area hard enough, they push everything downstream including sedimentary materials like leaves which eventually settle on top of pipes creating further blockages (this is why we see reports about flooded homes after big storms). Finally, improper installation or maintenance work by professionals such as plumbers or construction workers may also lead to drainage problems later on down the line.
