It is not needed to say that, drains flush away the water and debris out of the sink or bathroom. However, we cannot say that drains will never come up with clogs. Drains become clogged due to the buildup of food particles, grease, soap scum, hair binds and more. It is your duty to keep your drain clean.
Experiencing blocked drain or blocked sewer is not what any house owner or business establishment would like to go through at any point in time.
Over time, there might be the accumulation of debris, minerals or grease materials in your toilet, drains, bathtubs or shower which clog and hinder the free flow of water.
