Domestic Drainage
What Is Domestic Drainage and How Does It Work?
Domestic drainage covers everything from sinks, toilets and showers through to soil stacks and foul sewers within your home. A well-designed domestic drainage system collects wastewater from fixtures and conveys it safely away—either to a mains sewer, a septic tank or a treatment plant—using a network of buried pipes laid to fall.
How Does Domestic Drainage Work?
Our domestic drainage installations combine precision pipework with best-practice installation. Here’s how we deliver reliable drainage in The South of England and across the UK:
- Survey & Design: We inspect existing pipe routes, identify connection points, and design new runs to ensure correct falls (typically 1:40 to 1:60) and adequate venting.
- Excavation & Pipe Laying: Trenches are dug to safely accommodate 110 mm or 160 mm uPVC pipes on a stable bedding layer. Pipes are solvent-welded and tested for alignment.
- Jointing & Sealing: All fittings—bends, rodding eyes and inspection chambers—are installed with watertight seals to prevent leaks and odours.
- Backfilling & Compaction: Trenches are backfilled in layers, compacted around the pipe and topped with suitable material to protect the pipe and restore your yard or driveway.
- Connection & Testing: We connect to your chosen outlet (mains sewer, septic tank, etc.) and perform a water test to check for leaks and free-flow.
- Certification: You receive full As-Built drawings and, where required, Building Control sign-off for compliance with Part H of the Building Regulations.
Whether it’s a new build, an extension or replacing a failed run, our domestic drainage services keep your home flowing smoothly.
Benefits of Professional Domestic Drainage vs. DIY Clearing
When your home’s drains block or fail, you can try plungers and drain rods—or rely on a professional installation. Below we compare temporary DIY fixes with a full domestic drainage service in The South of England.
DIY Clearing (Plunging & Rodding)
- How It Works: Manual plungers or rods push through waste to break up simple blockages.
- Pros: Cheap and quick for minor sink or bath clogs.
- Cons: Doesn’t clear deeper build-up or collapsed runs. Can damage older pipes and offers no long-term solution.
Professional Domestic Drainage
- How It Works: Full survey, repair or replacement of pipe runs, and proper alignment to ensure lasting performance.
- Pros:
- Long-Term Reliability: New, correctly graded pipes eliminate sagging, root ingress and misalignment.
- Full Diagnostics: CCTV inspections pinpoint issues before you install or renew pipes.
- Regulation-Compliant: Meets Building Regs Part H and guarantees proper venting and backflow prevention.
- Improved Hygiene: Prevents sewage leaks, unpleasant odours and sewer gas ingress.
- Cons: Higher upfront cost than DIY, but far lower risk of repeat call-outs and emergency repairs.
For a robust, maintainable drainage system in The South of England, our domestic drainage installations are the clear choice over temporary fixes.
