Why Thornlie takes longer to work out
Much of Thornlie was built out through the sixties and seventies. That is decades before anything in Harrisdale existed, and it changes the job completely.
The plumbing has turned over, more than once
Original pipework has been replaced in sections over fifty-odd years, by different people, in different eras, to different standards. What is actually in the ground on a Thornlie property is frequently a patchwork rather than a system, and it is rarely recorded anywhere.
Materials are mixed
Older sections, newer sections, and joins between the two. Those joins — where somebody's repair from decades ago meets the original run — are a genuinely common place to find a leak.
Corrosion is back on the list
In the new estates we are chasing workmanship. Here we are also chasing age, because materials that were standard when these houses went up do not last forever.
Drainage is older
Thornlie drains are more likely to be earthenware, with joints that shift and let roots in. On big established blocks with fifty-year-old trees, that combination is the classic cause of a drain that keeps coming back. Blocked drains
The blocks are large
Long runs between the meter and the house, long runs to the back of the property, and plenty of ground for water to disappear into without a sign.
None of that makes a Thornlie leak hard to find. It makes it worth finding properly, because on a property with this much history, guessing where to dig is a genuinely bad bet.
The order we work in
The meter settles the first question. With everything off it should be still — if it keeps turning, you are losing pressurised water, and the speed gives us a rough size before we have looked at anything.
Isolating sections narrows it to one part of the property. Acoustic gear then pinpoints it, because escaping water makes a noise that carries along the pipe and through the ground.
In Thornlie there is often an extra step, which is simply working out what is actually buried there. Previous repairs, abandoned runs, capped lines from a bathroom that was moved thirty years ago. We would rather spend the time establishing that than open the wrong trench. How leak detection works
What we do in Thornlie
Leak detection
Service lines, slab and under-floor leaks, retic, and leaks at the joins between old and newer sections. Leak detection
Burst pipes
Older pipework fails faster once it starts. Water isolated first, then located, repaired and retested. Emergency plumbing
Blocked drains
Cleared, and then the cause established — on drains this age, a repeat blockage usually means damage, not habit. Blocked drains
Storm water and soakwells
Systems that have silted up over decades, and downpipe runs disturbed by fifty years of garden. Storm water and soakwells
Gas
Mains gas is widespread in Thornlie, and some of the gas runs here are old. Gas work is done under gas licence 13098. Gas leak repair
