Leak Detection in Pulborough: Pin-Hole Corrosion & Hidden Water Waste

We detect before we destroy — our non-invasive techniques mean your walls and floors stay intact even when the leak is buried deep. Serving RH20, RH21, RH22, RH23.

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.

Leak Detection

A Pulborough property in RH20 1EW reported rising water bills with no visible leaks or dripping taps. Our leak detection survey using thermal imaging and ground microphones located pinhole corrosion in the first-floor copper central heating circuit — caused by Thames Water's hard water attacking the newly installed pipework from inside. The leak was wasting 400 litres per day. Isolation and re-piping in plastic eliminated further water loss.

This describes typical work performed by engineers in our network. Names and specific details have been omitted to protect customer privacy.

Leak Detection in Pulborough — FAQs

How is pinhole corrosion detected in Pulborough's hard water supply?
Pulborough's Thames Water hard water creates pinhole corrosion in copper pipes, visible only on internal surfaces. We use thermal imaging to locate heat loss at leaking joints, combined with sound detection to pinpoint flows in buried supply pipes.
Why does Pulborough have more copper pipe corrosion than other areas?
Thames Water's hard water supply to Pulborough is high in calcium and magnesium, which corrode copper pipe interiors over 10–15 years. The issue is acute in RH20-RH23 where modern copper repipes meet hard water.
How do you find a leak without digging?
A combination of acoustic listening sticks, thermal cameras, moisture mapping and inert tracer-gas injection lets us triangulate a leak to within a few centimetres before any opening-up is needed.
Will my insurance cover the cost?
Most UK home-insurance policies include 'trace and access' cover for leak detection. We bill the insurer directly on approved claims.
What leaks can you find?
Mains supply leaks, central heating leaks, hot and cold pipework, underfloor heating, shower-tray leaks, and concealed waste-pipe leaks.
How long does a leak-detection visit take?
Typically 1-3 hours on site, followed by a written report within 48 hours suitable for insurance submission.
