Therefore, keeping these drains in shape involves using varying methods such as CCTV survey inspection, which will help know the issue behind the collapsed drains.

Pitch pipes have a shelf life of 40 years, and if taken care of correctly, their life span can also be increased by a little. The deterioration process is generally slow, which takes place because of the varying temperatures and harsh chemicals.
