Blocked Drains in Coventry
Coventry's separate sewer system requires specialist knowledge when drains block. Whether your Coventry property is a Victorian-era terraced house in CV2 or a modern home in CV3, blockages in the separate surface and foul drains demand rapid response. Our unblocking service handles both types of drainage across Coventry's CV1 to CV4 postcodes, with particular expertise in misconnected washing machines and root damage in older systems.
Blocked drains in Coventry typically result from misconnections in the separate sewer system, limescale from hard water, or failing clay pipes in Victorian homes. Coventry's CV2 and CV3 areas experience frequent blockages due to aging infrastructure and soap buildup in older properties.
Drainage in Coventry — what local engineers know
Coventry's water supply comes from Severn Trent Water, and the city's separate sewer system means misconnections between surface and foul drains are endemic across Coventry. Coventry City Council planning records show thousands of Victorian properties built with individual soak-aways that often fail. Limescale buildup from hard water is common, particularly affecting soil pipes and joint areas in Coventry homes. The high Victorian and Edwardian housing stock in Coventry means clay pipes and cast iron drains are at risk of failure, requiring specialist unblocking techniques beyond standard plunging.
- Hard water supply causes limescale accumulation in boilers, radiators and soil pipe joints — powerflush and descaling demand is high across Coventry
- Separate sewer system across most of Coventry: misconnections (e.g. washing machines plumbed into surface water drains) are a known local issue and can result in environmental enforcement action
- Ageing infrastructure in parts of Coventry means drain blockages from grease, wipes and root ingress remain the most common call-out reasons
- With a significant share of properties built before 1920, salt-glazed clay drainage and lead-solder copper pipework are common — pipe collapse, root ingress and joint failure are recurring call-out drivers.
- Coventry has Environment Agency flood warning areas nearby along the Sowe corridor — basement and ground-floor properties can face sewer backflow during heavy rain; non-return valves are strongly recommended.

Who's responsible for drains in Coventry?
In Coventry, responsibility for a blocked or damaged drain depends on where the fault sits. As a homeowner you are responsible for the drains within your property boundary that serve only your home. Since the 2011 private sewer transfer, Severn Trent Water is responsible for shared sewers and lateral drains beyond your boundary — even where they run under private land. Road gullies and highway drainage are maintained by Coventry.
This matters because it determines who pays. If our engineer's CCTV inspection shows the fault is in a shared sewer, we'll tell you — and you can report it to Severn Trent Water rather than paying for the repair yourself. The separate sewer layout that dominates Coventry affects where these boundaries typically fall, and our local engineers know the CV1, CV2, CV3 networks well enough to identify ownership quickly.
