Leak Detection in Chichester
Chichester's separate sewer system and mixed property stock — from Victorian terraces to postwar homes across PO19 and PO20 — creates specific leak challenges. Hard-water limescale builds up in boilers, radiators and soil pipe joints, while pre-1920 properties often have lead-solder copper pipework prone to pin-hole corrosion. Finding these leaks without invasive damage is critical.
Leak detection in Chichester uses non-invasive acoustic, thermal imaging and tracer gas methods to find hidden leaks without tearing up floors or walls. Southern Water's hard water and Chichester's pre-1920 properties make pin-hole corrosion and joint failure common. Insurance often covers trace-and-access repairs.
Drainage in Chichester — what local engineers know
Southern Water supplies Chichester's postcodes with notably hard water, accelerating pin-hole corrosion through copper heating circuits and soil pipe joints. Chichester Council oversees a High flood-risk area where properties near the River Test, River Itchen and River Meon face sewer backflow risk — a driver for basement and ground-floor properties to install non-return valves. The separate sewer network increases misconnection hazards (washing machines mistakenly plumbed into surface water drains), and coastal salt-laden air corrodes external soil stacks and galvanised fittings. For pre-1920 homes with lead-solder joints, thermal imaging and acoustic testing pinpoint deteriorating pipework before catastrophic failures.
- Hard water supply causes limescale accumulation in boilers, radiators and soil pipe joints — powerflush and descaling demand is high across Chichester
- Separate sewer system across most of Chichester: misconnections (e.g. washing machines plumbed into surface water drains) are a known local issue and can result in environmental enforcement action
- High flood risk in Chichester: basement and ground-floor properties near watercourses are vulnerable to sewer backflow — non-return valve installation is strongly recommended
- Coastal salt-laden air in Chichester accelerates corrosion of external soil stacks, pipe brackets and galvanised fittings on exposed elevations
- With 26% 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.

Who's responsible for drains in Chichester?
In Chichester, 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, Southern 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 Chichester.
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 Southern Water rather than paying for the repair yourself. The separate sewer layout that dominates Chichester affects where these boundaries typically fall, and our local engineers know the PO19, PO20, PO21 networks well enough to identify ownership quickly.
Leak Detection prices in Chichester
Every Chichester job is quoted as a fixed price before work starts — what we quote is what you pay, with no call-out fee for providing the quote. The final price depends on access (an external inspection chamber is quicker than internal-only access), the pipe material and condition , and how established the blockage or fault is. Request your free quote and we'll confirm the price and your engineer's ETA in the callback.
