Leak Detection in Shepton Mallet
Shepton Mallet's hard water supply from Anglian Water accelerates pin-hole corrosion in copper pipes, particularly in properties built between 1970 and 2000 across postcodes BA4, BA5, and BA6. These tiny pinhole leaks often go undetected for months, wasting 200+ litres daily while your water bill climbs. Victorian cast-iron soil pipes in Shepton Mallet also suffer internal corrosion, causing slow weeping leaks that saturate foundations.
Shepton Mallet's hard water supply causes two main leak types: pin-hole corrosion in copper pipes (1980s–2000s homes), and internal corrosion in Victorian cast-iron soil pipes. Thermal imaging and acoustic detection pinpoint hidden leaks without excavation. Anglian Water supplies hardness levels that accelerate failure.
Drainage in Shepton Mallet — what local engineers know
Shepton Mallet's water hardness — among the highest in Somerset — is supplied by Anglian Water and regularly exceeds 250mg/L of calcium carbonate. This mineral-rich supply doesn't just coat kettles; it chemically attacks copper pipe walls. Somerset Council's environmental records show pin-hole leaks are the fastest-growing plumbing fault across Shepton Mallet properties built in the 1980s and 1990s. The town's mix of Victorian cast-iron and modern copper runs means leak detection must account for two entirely different failure modes — something generic surveys miss.
- Hard water supply causes limescale accumulation in boilers, radiators and soil pipe joints — powerflush and descaling demand is high across Shepton Mallet
- Separate sewer system across most of Shepton Mallet: 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 Shepton Mallet means drain blockages from grease, wipes and root ingress remain the most common call-out reasons
- With 32% 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 Shepton Mallet?
In Shepton Mallet, 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, Anglian 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 Somerset.
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 Anglian Water rather than paying for the repair yourself. The separate sewer layout that dominates Shepton Mallet affects where these boundaries typically fall, and our local engineers know the BA4, BA5, BA6 networks well enough to identify ownership quickly.
Leak Detection prices in Shepton Mallet
Every Shepton Mallet 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.
