Can A Plumber Do Drainage? Expert Guide

Can a plumber carry out drainage work in the UK?

Yes, a plumber can carry out certain drainage jobs, but it depends on where the problem is and what’s causing it. In towns like Reading and across Berkshire, drainage infrastructure is often affected by older Victorian systems, dense housing, and a mix of private and shared pipework. This makes it even more important to identify the exact source of a problem before calling out a professional. If it’s something like a blocked toilet, slow draining sink, or an issue with waste pipes inside your home, a plumber is usually the right person to call. But if the problem is outside your home, like a collapsed drain or a blocked sewer, that’s when a trained drainage contractor is needed. The type of professional you need depends on whether the issue is with water coming into your home or waste water going out.

When Can a Plumber Handle Drainage Tasks?

Plumbers are well equipped to fix many internal drainage problems. This includes clearing small blockages inside sinks and baths, replacing damaged waste pipes, and checking under sink traps. These types of jobs are part of a plumber’s daily work and usually don’t require any specialist drainage equipment.

Typical Internal Drainage Jobs for Plumbers

  • Unblocking sinks or baths that drain slowly
  • Replacing or repairing waste pipes under the sink
  • Fixing leaking u bends or traps
  • Sorting out odours from plugholes

If the blockage is local and hasn’t affected any other part of the house or the external drains, a plumber can usually sort it out with basic tools.

Signs the Issue is Plumbing, Not Drainage

  • Water backing up in one sink only
  • Smell isolated to one room
  • Leak beneath a visible pipe
  • Toilet fills but doesn’t flush properly without external flooding

These are usually jobs that don’t need CCTV inspections or specialist drainage tools, and can often be fixed on the spot by a qualified plumber.

When You Need a Specialist Drainage Contractor

Some problems go beyond what a plumber can safely and legally handle. Drainage contractors are trained and licensed to work on underground and external drainage systems. They have the right tools such as high pressure water jetting machines, CCTV survey cameras, and confined space access kits.

Common Jobs for Drainage Engineers

  • Clearing blocked external drains or manholes
  • Repairing or replacing collapsed pipework beneath gardens or driveways
  • Conducting CCTV drain inspections to diagnose hidden faults
  • Installing or maintaining soakaways, gullies, or interceptors
  • Managing flood incidents linked to drain failures

Drainage engineers frequently collaborate with water authorities and local councils. They must meet compliance standards such as those outlined in the New Roads and Street Works Act. In many cases, permits or council approvals are required before any excavation work begins.

Signs You Need a Drainage Specialist

  • Waste water backing up through outdoor gullies
  • Overflowing manhole covers
  • Bad odours near outside drains
  • Repeat blockages even after plumbing work
  • Surface dips or cracks in driveways or patios

These indicators often point to issues within the external drainage infrastructure and are best resolved by trained professionals with the appropriate certifications.

Pro Tip: If you live in a flood prone zone like central Reading, schedule an annual drainage inspection before autumn to avoid winter emergencies

Equipment Differences Between Plumbers and Drainage Engineers

What Plumbers Use

Plumbers generally work inside the property, using tools suited to indoor systems. These include:

  • Pipe wrenches and adjustable spanners
  • Manual drain snakes
  • Pipe cutters and pressure gauges
  • Torches for soldering copper fittings

These tools are ideal for clearing basic blockages, repairing internal pipes, and connecting kitchen and bathroom fixtures.

What Drainage Engineers Use

Drainage specialists are equipped for outdoor and underground work. Their equipment includes:

  • Water jetting machines for high pressure drain cleaning
  • Robotic cutting tools for clearing obstructions
  • CCTV drain cameras for inspections
  • Excavation tools and confined space safety gear
  • Waste disposal tankers and vacuum systems

Their technology also includes drain tracing software and moisture detection systems, particularly useful for pre purchase surveys and commercial drainage audits.

Real Case Example: Plumber and Drainage Team Working Together

A homeowner in Reading called in a plumber to inspect a slow flushing toilet. The plumber found that although the cistern and internal waste pipe were working correctly, water was backing up in the external gully. This indicated a blockage beyond the internal system.

The plumber contacted 24hrs Drainage. Our drainage engineer attended within two hours, performed a CCTV drain inspection and identified a section of collapsed clay pipe. This was located under the customer’s patio. The team carried out a localised excavation, replaced the faulty section with new UPVC pipe, and reinstated the area cleanly. The system was tested thoroughly, and normal flow was restored.

This situation showed how internal plumbing issues can be linked to external faults, and how a coordinated response avoids delay and repeat visits.

Who should you call in an emergency plumbing or drainage situation?

Fast action matters when water or waste starts causing damage. But knowing who to call can make the difference between a quick repair and ongoing disruption.

Plumbing Emergencies

You should call a plumber when:

  • A pipe bursts indoors
  • A tap won’t stop running
  • A toilet is leaking from the base

These types of issues usually relate to internal supply or waste systems and are often resolved with standard plumbing tools.

Drainage Emergencies

You need a drainage engineer when:

  • An outdoor drain is overflowing
  • Water is backing up into the home through plugholes
  • There are smells of sewage in the garden or basement

At 24hrs Drainage, our team is on call day and night. We can be at your door in under sixty minutes for urgent call outs and bring all necessary equipment for repairs, clearance or inspection.

Plumbing vs Drainage: What are the cost differences?

Estimated Charges for Plumbing Work

  • Hourly rates range from £40 to £80 depending on region and time of day
  • Emergency plumbing visits may start from £100
  • Minor repairs like pipe resealing or trap replacement cost between £60 and £120

Estimated Charges for Drainage Services

  • Hourly charges are typically higher due to specialist tools, from £60 to £120
  • Emergency clearance or jetting can cost £120 to £250
  • CCTV drain surveys generally cost £100 to £250 based on property size

To avoid surprise fees, ask for a clear written estimate. At 24hrs Drainage, we offer full pricing transparency. This includes pre agreed rates, no call out fees, and a breakdown of any additional costs before starting the work.

Upfront pricing and properly diagnosing the issue early prevents avoidable follow up visits and keeps your system working long term.

Do plumbing and drainage jobs need to meet UK regulations?

Yes, both plumbing and drainage jobs must follow specific building and water regulations in the UK. For plumbing, the Water Supply (Water Fittings) Regulations ensure that all fittings and pipework protect the water supply from contamination. Plumbers should work to WRAS approved standards.

Drainage work must comply with Building Regulations Part H. This includes rules around foul water disposal, surface water drainage, and backflow prevention. Drainage engineers working on public land need accreditation under the New Roads and Street Works Act. Some drainage jobs may require planning consent or building control approval, especially when altering shared systems or digging near foundations.

Hiring professionals who understand and follow these rules helps protect health and property and avoids potential legal issues.

How to choose the right professional for your drainage or plumbing issue

Start by identifying where the problem is happening. If it’s inside the house and relates to supply pipes or waste traps, a plumber is usually the right choice. If the problem is outside or affects multiple fixtures, a drainage contractor may be needed.

Look for the following when hiring:

  • Proof of insurance and public liability cover
  • Membership of a recognised trade body
  • Positive customer reviews
  • Transparent pricing and detailed quotes
  • Emergency availability if needed

If you’re unsure, contacting a company like 24hrs Drainage ensures the right person is sent out for the job. Our dispatch team asks the right questions to direct you to either a qualified plumber or drainage engineer.
