The purpose of drains is to flush away all of the waste away from the home. Considering the fact that most of this waste consists of dirty water, food particles, hair, soap, grease, tissue and human waste, it is little wonder why blockages can often build up in sewer lines. In order to prevent such blockages, there are many precautions that can be carried out.
The main way to prevent blockages is to ensure that only water from toilets, sinks and baths is flushed away, along with any human waste and tissue paper. Anything else should be thrown in the bin. To avoid waste such as hair and food scraps getting washed away, it is advisable to place filters over your drains. Oil, fat and grease are sometimes poured down the drain and as they are in liquid form when disposed of, most people fail to realize that when they cool down, they congeal and easily clog up sewer lines. The best way to dispose of them is to wait for them to cool down then throw them in the bin.
