To help minimise drain customers we always advise our customers to "think when you are at the sink!". If you do get a drain blockage, boiling water and/or a drain snake as the best ways to help clear any internal blockages.
Many drain blockages are caused by sanitary products and another top cause is fat, oil and grease. Some of the other worst offenders are items such as cleansing wipes, cotton buds and nappies.
By thinking about what you put down your toilets, sinks and drains, you can help to reduce blockages and decrease the risk of flooding. A blocked sewer is, of course, inconvenient for our customers but if it leads to sewer flooding it can be extremely unpleasant and stressful too.
To help reduce more serious drain blockages, never pour oils down the drain, this includes oil based paint and try to limit the use of any garbage disposal. Reducing the fats, grease and solids that enter your system will reduce that build up of grime that enters your system and this is even more important if you have a septic tank.
Oil or grease float on water and they pose a threat of clogging the inlet pipes by filling up the upper part of a septic tank. This oil can also transfer into the transport pipes, solidify, and cause excessive buildup that can cause blockages.
