Commercial drains often differ from domestic drains in their size and capacity, yet are not exempt from the same kinds of issues.
One of the most common commercial drainage problems is blockage. A little bit of education and preventive maintenance goes a long way to avoid the unpleasantness that blockages can cause.
Mind what you drop down the drains or flush into the toilets. Sanitary products, baby nappies, hair, dental floss, paper and toys are some of the most common causes of blockage; besides these, grease and kitchen waste are also troublemakers. Blockages caused by kitchen waste can be treated easily enough; but as for the rest, it is best you take care.
Since a single blockage could create multiple problems, preventive measures like regularly pouring hot water down the drain should keep drains clear of grease and fat.
Furthermore, a solution of bicarbonate of soda and vinegar usually takes care of the more stubborn build up that escapes the hot water treatment. Nevertheless, follow this with more hot water.
When you do this every three months, you won’t have to deal with as many minor drain blockage problems. It pays to bear in mind that it’s not just the inside of the drains that need attention, but you also need to ensure that the outside portion meeting the ground is clear of debris, leaves, twigs or nests.
Sometimes, despite all measures, you may still end up with a blockage that DIY remedies can’t treat; or you may have old and damaged drainage systems that cause steady deterioration resulting in blockages, slow draining or annoying leaks. In the case of the latter, your drains may need re-lining. This is a chemical process that hardens and restores the weak sections of the system.
When the cause of the blockage is unknown, CCTV inspections are used to ascertain it. Drain rodding and high water pressure are some of the methods used to remove debris.
Sometimes, the blockage is caused by roots and they have to be cut and removed with specialised tools. The problem with roots is often the damage is so extensive that the sections may need to be excavated and replaced. The roots of Ficus Elastica – an innocent looking, ornamental plant on NASA’s air purifying plant list – causes such damage. So, it should never be planted on the ground, no matter how far away it is from the drainage system.
Drain jetting is another way professionals remove blockages, but is often used as a preventive measure to keep the buildup of grime and grease at bay, especially from commercial kitchen drains.
Course of Action
If you have a blocked drain, first check to see who is responsible for looking after that particular section of the drain – you or the water control board (all lateral drains and public sewers are the water company’s responsibility).
However, if the area that has the blockage does not fall under the jurisdiction of the water control board, then you are responsible for it and you will want to bring in professionals who know their business.
