Problems we often see in Portsmouth

When customers in and around Portsmouth contact us about drain unblocking, these are some of the most common issues:

  • Shared rear drains in terraced streets backing up into several homes
  • Blockages in flats and shared houses in Southsea and Fratton
  • Grease-blocked drains in restaurants and takeaways
  • Roots in older drains on the mainland suburbs

What usually causes them

  • Wet wipes, sanitary products and kitchen roll flushed down toilets
  • Fat, oil and grease poured down kitchen sinks, which hardens in the pipe
  • Food waste, coffee grounds and rice collecting at bends
  • Hair and soap residue in bathroom waste pipes
  • Leaves, silt and debris washed into outside gullies

Drain Unblocking across Portsmouth

Portsmouth is one of the most densely populated cities in the UK, and most of Portsea Island is made up of Victorian and Edwardian terraces. Many of these streets have a shared drain running behind the houses, so a blockage in one section can back up into several homes. Shared drains are generally the water company’s responsibility, so it is important to find out exactly where the blockage is.

Southsea and Fratton have large numbers of flats and houses in multiple occupation, and heavy use combined with wipes and fat makes blockages frequent. The city’s restaurants, cafés and pubs add a commercial dimension, particularly around Albert Road, Elm Grove and Gunwharf.

On the mainland, Cosham, Drayton and Farlington have more inter-war and post-war housing, with drainage problems more often linked to roots and household waste.

What Clear Drainage does

Clearing blocked drains, gullies and waste pipes at homes and businesses, then explaining what caused the blockage so it is less likely to come back.

  • The blockage is traced to its source rather than just pushed further down the pipe.
  • You are told what caused the problem in plain English, with practical advice on preventing it.
  • Where a drain looks damaged, you can choose whether to investigate further with a CCTV survey.
  • The method is matched to the drain, from simple rodding to high-pressure jetting.

When to call us

Get in touch if you notice any of the following at your Portsmouth property:

  • Water rising in an outside gully or inspection chamber
  • Sinks, baths or showers draining slowly or not at all
  • Toilets filling higher than usual or slow to clear when flushed
  • Gurgling from plugholes or the toilet after water drains elsewhere
  • Unpleasant smells from drains, gullies or manhole covers
  • Water or waste backing up at the lowest point in the property

What to expect

How a drain unblocking job in Portsmouth usually works, from your first call to the drain running freely.

  1. Tell us about the problem

    Call or send an enquiry with your postcode and what you are seeing: which fittings are affected, whether water is rising outside and how urgent it is.

  2. Locate the blockage

    We check the affected fittings and lift inspection chambers where accessible to work out where the drain is blocked and which section is affected.

  3. Clear the drain

    The blockage is cleared using the most suitable method for the pipe (rodding, mechanical clearance or water jetting), and the drain is flushed through.

  4. Test and explain

    We run water through the system to confirm it is flowing, then explain what caused the blockage and whether anything else needs looking at.
