Drainage FAQs

Often, drains will become blocked because of the items either flushed down the toilet (sanitary items, dental floss, nappies), or disposed of down the sink (food, oil, grease, fat). However, drains can also become blocked because of structural damage or even ingress from tree roots. The experts at ClearFirst Drainage will be able to identify the cause of any blockages using state of the art survey equipment.

There are numerous visual, odorous and audible warning signs of a blocked drain, these include:

  • Slow draining sinks
  • High water level in toilets
  • Water bubbling from drains
  • Sulphurous/foul odours from drain covers
  • Gurgling in pipes

To learn more about these signs, read our handy blocked drains guide.

This depends on the size and nature of the blockage. Our engineers will survey your drains before taking appropriate action, and will aim to resolve your problem within an hour - but it could take longer.

The best way to prevent future blockages is to avoid flushing non-dissolving/non-biodegradable items down your drains. You should scrape food, cooking oils and fats into bins, and never try to flush nappies, sanitary items (including condoms) or plastics down the toilet. Regular drainage surveys are also recommended.

If you experience recurring drainage issues - slow flushing toilets, regular blockages etc. - then a CCTV survey should get to the root cause, allowing your contractor to resolve the problem for good. A CCTV survey can identify issues that would otherwise remain hidden, so it’s definitely useful to have a survey done if you think something is amiss.

For older houses, or homes with a known history of drainage issues, a CCTV survey is definitely recommended. This will identify existing problems as well as potential trouble in the future - this could affect sale price, or even affect your final decision on the property.

Drain relining is an effective way of reinforcing a repaired drainpipe in order to prevent the same kind of issue recurring in the future. Drains that have suffered root damage are common candidates for relining. New pipe lining adds a sturdy internal layer which is installed without the need for excavation, adding effective protection and helping to improve water flow in the pipes themselves.
