Why Drains Block in Bognor Regis and How to Prevent It

2 min readBognor RegisBy AA Drainage

Bognor Regis sits on low, flat land close to the sea, which brings its own drainage challenges. Here are the causes we see most often and what you can do about them.

Common causes of blockages

Most blockages build up slowly before they cause a problem. In Bognor Regis we regularly find:

  • Fat, oil and grease poured down kitchen sinks
  • Wet wipes and sanitary products flushed down toilets
  • Sand and silt washed into older clay pipes
  • Tree and shrub roots entering cracked joints
  • Pipes that have sunk or dipped, so waste collects in low points

Why low-lying ground matters

Pipes need a steady fall to carry waste away. On flat land the fall can be shallow, so any settlement or dip can stop water moving. A high water table also puts pressure on damaged pipes.

A CCTV drain survey shows exactly where the problem is, so repairs can be targeted rather than digging up a whole garden.

Simple prevention tips

Bin fats and wipes, fit sink strainers, and keep an eye on gullies after autumn leaf fall. If you notice slow draining, gurgling or bad smells, get the drain checked early before it becomes a costly repair.

Frequently asked questions

Can tree roots really break drain pipes?

Roots look for moisture and will enter small cracks or loose joints, then grow and widen them over time.

Do you replace old clay drains?

Yes. We excavate and relay damaged runs in modern plastic pipe with the correct fall.
