Drain Survey: Are You Pouring More than Fat Down the Drain?

Are You Pouring More than Fat Down the Drain?

The aftermath of the festive season might typically lead to spike in gym membership, but it can also spell trouble for drains and sewers. Recent estimates from scientists suggest that removing grease, oil and fat from the drainage network totals around £50m a year on UK household bills.

Another significant figure is the 15 million cups of roast turkey fat we pour down the kitchen sink on Christmas day; and in terms of the cost, you could be pouring a lot more than fat down the drain.


What Happens to Fat in Sewers?

The sewer system is designed to transport waste by using water. Adding fat and grease to the system will eventually clog it up, impeding its flow. A blocked sewer, backed up to your drain is more than an inconvenience: it is also a potential health risk.

Your kitchen sink plughole is connected to the sewer, and when you pour oil, fat and grease down it, this forms into a hard, chalky substance which is really difficult to then remove.

Over time, fatty acids transform from an unsaturated to saturated form, and this is one of the ways scientists think this hard substance forms.


Diagnosing Drainage Problems


If fat and grease starts to coat the internal walls of pipes, it can start to affect how well a drainage network performs, as it cools, hardens and reduces the diameter of the pipework.

For domestic drains, fat tends to gather and solidify in the area beneath the sink, which can then make a difference to how efficiently water drains out of the sink.

For this kind of persistently sluggish drainage, or where there are frequent blockages, a drain survey is the ideal method for diagnosing the problem. Using CCTV cameras and sonar drain tracing, we can develop a clear idea of the state of your drains. If there are blockages, we will pinpoint exactly where they are; and if there are weaknesses in the system, our survey will expose these.

A drain survey is a cost effective way of professionally diagnosing drainage problems, and provides the necessary information for us to take effective remedial action.

If you’re experiencing blocked or slow drains, limit how much oil, fat and grease you’re putting down them and give us a call.
