Grease and fat are particular culprits in the blockage of drains, and yet despite being one of the primary causes it is in fact one of the easiest to stop.
Hair may seem too fine to cause any major blockage, but over time it can develop into a major problem, in some cases stopping water passing through it altogether.
Although food and hair make up a large chunk of the problems we are needed to resolve, you'd be amazed at some of the things that end up being flushed down the drain, from nappies and sanitary products to toys and even valuables.
