Practical, Guaranteed Drainage Across Liverpool & Southport & Merseyside
When an outside gully is overflowing with foul waste, a toilet is backing up, or an underground pipe has cracked, you need an experienced engineer with the right kit on the van. At Liverpool One Drainage, we diagnose and fix domestic and commercial drainage faults permanently—with upfront pricing and zero call-out surprises.
Specialist Drainage Solutions & Repairs
We do not believe in quick, temporary plunges that block back up three days later. Every job starts with clearing the immediate obstruction and checking why it happened in the first place. Select a service below to see how we work.
Emergency Drain Unblocking
Fast clearance for overflowing external gullies, backed-up manhole chambers, blocked toilets, sinks, and main soil stacks. We use van-mounted high-pressure water jetting (HPWJ) at controlled pressures to cut through solidified fatbergs, wet wipes, and heavy silt without damaging older clay pipes.
- 24/7 response for internal & external flooding
- Mechanical coring for dense root masses
- Full wash-down and sanitisation of spills
CCTV Drain Surveys & Tracing
Stop guessing what is happening underground. We feed self-levelling HD push-rod cameras and robotic crawlers into your pipework to pinpoint displaced joints, root ingress, collapsed pitch-fibre sections, and hidden defects. Ideal for recurring blockages or pre-purchase home buyer checks.
- Live on-site monitor view & digital recordings
- Home buyer & mortgage lender structural reports
- Sonar sonde tracing to mark exact depth & route
No-Dig Drain Relining & Patching
Fix cracked clay pipes, leaking collars, and root-damaged runs without digging up your driveway, patio, or extension floor. After rotary root cutting and jetting, we invert a resin-impregnated CIPP liner or pneumatic silicate patch through the existing manhole to form a smooth new structural pipe inside the old one.
- Zero excavation—protects driveways & landscaping
- Localised 1-metre silicate patch repairs
- Full-length continuous resin pipe lining
Drain Excavation & Pipe Replacement
When a sewer has completely collapsed, bellied into shifting ground, or lost its fall, open-cut excavation is the only lasting solution. We locate the exact fault with sonar so we only dig where necessary, replace the failed section in modern uPVC or clay, and reinstate the surface cleanly.
- Collapsed sewer & pitch-fibre pipe replacement
- Brick manhole reconstruction & chamber benching
- New gully installations & drain diversions
Commercial Drain Maintenance (PPM)
A blocked drain or overflowing grease trap can shut down a restaurant, hotel, school, or warehouse immediately. We provide scheduled out-of-hours jetting, stack-pipe descaling, silt removal, and grease management across Liverpool City Centre, the Baltic Triangle, and surrounding industrial estates.
- Planned preventative maintenance schedules
- Commercial kitchen grease trap servicing
- Urinal & multi-storey soil stack descaling
Drain Pest Control & Rat Blockers
If you hear scratching under floorboards or behind kitchen kickboards, rats are likely entering your property cavity via redundant drain branches or displaced sewer joints. We survey the network to find their entry point, seal redundant lines, and install marine-grade stainless-steel non-return rat flaps inside the inspection chamber.
- 316 stainless-steel one-way rat valves
- CCTV defect tracing for burrowed pipe joints
- Capping off disused toilets & dead-leg drains
How We Diagnose & Resolve Your Drainage Fault
Whether we are lifting a heavy cast-iron manhole lid in a shared rear alleyway in Wavertree or investigating a slow-draining kitchen gully in Formby where sandy subsoils have shifted the pipework, our approach on site stays consistent.
Clear Upfront Assessment
We lift the inspection chambers, trace the flow, and explain the exact work and cost before switching on the machinery. If the blockage sits on a shared lateral sewer that falls under United Utilities' responsibility, we will tell you straight away so you do not pay for work the water board should cover.
Controlled Jetting & Mechanical Clearance
We match our equipment to the pipe material. Brittle salt-glazed clay and pitch-fibre pipes require carefully regulated water pressures and specialist Warthog or rotary heads to strip scale, grease, and roots cleanly without fracturing the pipe wall.
Camera Verification & Site Disinfection
Once the water drops and flows freely, we check the line to ensure no underlying structural crack or dropped collar caused the backup. Before leaving, we hose down and disinfect any affected patios or driveways and secure all manhole covers cleanly.
Not Sure If a Blocked Drain is Your Responsibility?
As a rule of thumb, you are responsible for private drains inside your property boundary that serve only your home. Once your pipe joins a neighbour's drain (a shared lateral drain) or passes outside your boundary into the main road sewer, maintenance usually falls to United Utilities. Give us a ring and describe which gullies or manholes are backing up—we will happily talk you through it over the phone.
