Leak Detection in Pulborough
Thames Water's hard water supply across Pulborough (RH20, RH21, RH22, RH23) accelerates pin-hole corrosion in copper pipework — a silent problem that wastes water for months before damage becomes visible. Pulborough's older properties combine two leak vulnerabilities: hard-water corrosion of newer copper repipes, and scale-induced stress fractures in original cast-iron drains and lead externals. A leak detection survey in Pulborough isolates where water is escaping and quantifies waste.
Leak detection in Pulborough identifies pinhole corrosion in copper pipes caused by Thames Water's hard water, and frost-damaged externals in older properties. Thermal imaging and acoustic sensors locate hidden leaks in supply and drainage systems across RH20-RH23.
Drainage in Pulborough — what local engineers know
Pulborough falls within Horsham's Thames Water supply zone, which is classified as a hard-water area — calcium and magnesium salts in the town's water supply accelerate corrosion of copper pipe interiors, causing microscopic holes and pinhole leaks. The town's Victorian and Edwardian building stock (34% of Pulborough's housing) typically combines hard-water exposure with original cast-iron externals subject to scale-induced cracking. Pulborough properties also suffer from uninsulated buried pipes in gardens, which freeze and split during winter. Combined, these factors mean Pulborough has high prevalence of hidden leaks in both supply and drainage systems.
- Hard water supply causes limescale accumulation in boilers, radiators and soil pipe joints — powerflush and descaling demand is high across Pulborough
- Separate sewer system across most of Pulborough: 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 Pulborough: basement and ground-floor properties near watercourses are vulnerable to sewer backflow — non-return valve installation is strongly recommended
- With 34% 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 Pulborough?
In Pulborough, 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, Thames 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 Horsham.
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 Thames Water rather than paying for the repair yourself. The separate sewer layout that dominates Pulborough affects where these boundaries typically fall, and our local engineers know the RH20, RH21, RH22 networks well enough to identify ownership quickly.
Leak Detection prices in Pulborough
Every Pulborough 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.
