Everyday substances that pass through our drains and pipes including fat, grease from food and cooking, as well as many other substances and objects that really shouldn’t be entering the drainage system. This can cause a build-up of deposits in drains and pipework that eventually causes blocked drains. Invariably this is accompanied by scale content (an accumulation of acids within human waste and lime from water), as well as other dirt and debris including concrete, silt, mud, stones and in some cases tree and shrub roots that have managed to grow through a gap or breach in the pipework.
All of these factors can combine to cause a blocked drain or blockages in the pipework or your drainage system. A continuous or regular build-up of any of these substances, or a breach by roots into your drainage system can lead to recurring blockages. If left unchecked this can also lead to overflowing drains and in some cases damage that will require drain repairs or for pipework to be either lined or replaced.
