Leak Detection in Falmouth
Water escaping from copper pipes is the most common leak signature in Falmouth properties, particularly those supplied by South West Water's soft-water network. Falmouth's separate sewer system means surface-water pipes are isolated from foul drains, but pinhole corrosion from mineral-rich water still eats through copper in boilers, radiators, and distribution pipes across postcode areas TR11 and TR12. Finding the leak before water damage spreads requires specialist equipment, not guesswork.
Leak detection in Falmouth identifies hidden water escapes from corroded copper pipes caused by the local water exposure. Specialist equipment like thermal imaging and pressure gauges pinpoints leaks in supply, heating, and surface-water systems without damage to walls or flooring.
Drainage in Falmouth — what local engineers know
South West Water supplies Falmouth with low mineral levels that accelerates copper corrosion. Cornwall Council's building standards require annual maintenance checks on pre-1980 properties within designated zones, and many Falmouth homeowners in TR12–TR14 discover leaks during routine inspections. The separate sewer network adds complexity: a leak in surface-water pipework can go unnoticed for months because water doesn't back up into the property. Falmouth's Victorian and Edwardian housing stock is particularly susceptible to pinhole corrosion after 40+ years of the local water exposure.
- Water hardness (30–100 ppm CaCO3, soft) supplied by South West Water: South West Water is naturally soft (30–100 ppm CaCO3) — local ground conditions in Devon and Cornwall produces some of the softest mains water in England.
- Separate sewer system across most of Falmouth: 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 Falmouth means drain blockages from grease, wipes and root ingress remain the most common call-out reasons
- Parts of the Falmouth area fall within Environment Agency flood alert areas along the River Kenwyn corridor — sewer surcharge during prolonged rainfall is a known risk; non-return valves are worth considering.

Who's responsible for drains in Falmouth?
In Falmouth, 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, South West 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 Cornwall.
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 South West Water rather than paying for the repair yourself. The separate sewer layout that dominates Falmouth affects where these boundaries typically fall, and our local engineers know the TR11, TR12, TR13 networks well enough to identify ownership quickly.
Leak Detection prices in Falmouth
Every Falmouth 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. However, 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.
In summary, Leak Detection in Falmouth is backed by a 12-month workmanship guarantee. Furthermore, every job includes a written completion report. Consequently, you have full documentation if the same fault recurs.
