Biofilm or fungal development in pipework can be a long-term source of clogging. Another frequent issue is the settling of particle matter and the accumulation of things such as food and hair. If the drains and sewer lines are not properly cleaned or are only partially cleaned, the accumulation of particulates will continue and cause another clog. Therefore, to ensure that they function correctly, cleaning them at the appropriate intervals and clearing out any obstructions is essential.
