A real person answers, day or night
The clues rarely point straight at the actual cause
An account that's grown for no obvious reason and a patch of lawn refusing to dry out can look like two separate problems, yet both are textbook signs of the same hidden fault. Ring (02) 9072 0597 and walk us through what's been happening.
Ground and pipework both play a part here
- Galvanised supply pipe from the postwar build-out corrodes from the inside long before it visibly fails Restricted flow often shows up well ahead of any actual leak, and the same testing that traces water loss catches that internal narrowing just as reliably.
- Stony, shallow ground across much of the ridge doesn't move much, but it doesn't need to move much either Even minor seasonal shifting puts steady, ongoing stress on old pipe joints, which is precisely the sort of gradual wear listening equipment picks up well before a full failure.
- A steeply falling block near Waratah Parade or Ara Crescent changes how far escaping water actually travels Rather than pooling near where a pipe has failed, water follows the fall toward the Dee Why valley catchment, sometimes surfacing well downhill from the real source.
Leak detection services we cover
Locating water loss precisely, whatever the pipe, the property or the era involved:
Slab and underground tracing
Your plumber splits the property into zones and runs each under controlled pressure, ruling sections in or out until listening equipment can point to a specific fitting worth actually digging up.
Wall cavity and ceiling leaks
Your plumber follows dampness moving through a cavity or behind a wall back to its genuine cause, separating an actual plumbing fault from roof damage or waterproofing failure that can present almost identically.
Water account jump investigations
Your plumber works outward from the meter when a quarterly bill can't be explained, checking each fixture in turn until whatever's genuinely responsible gets identified rather than assumed.
Pre-purchase leak inspections
Booking a check ahead of a purchase turns an unknown into a confirmed fact, so whoever's buying knows exactly what the plumbing's actually doing before they're the one legally responsible for it.
What era and ownership change about a leak search
- No history of problems doesn't mean a property's genuinely in the clear Original galvanised pipe corrodes quietly for years before restricted flow ever announces itself, which is why age on its own justifies a proper test.
- A renovated property swaps one kind of risk for another entirely Modern fittings under a kitchen or bathroom sink can fail suddenly if installed poorly, unlike the slow pinhole failure typical of old steel pipe.
- A tenanted property adds a communication step an owner-occupied home skips Getting the finding to whoever's responsible for the repair happens quickly, but it's still an extra link in the chain compared with a straightforward private booking.
Common leak detection problems
Consecutive bills that keep climbing for no clear reason
The household's habits haven't shifted at all, yet each new bill lands higher than the last, and shrugging that pattern off tends to prove far more expensive than simply having it checked properly.
A patch of lawn or garden bed that never quite dries out
Whether it's the middle of a dry spell or straight after rain, ground that stays consistently wet almost always has an underground source, and finding it before it spreads keeps the fix manageable.
Why chasing a hidden leak early actually pays off
The longer water keeps escaping into timber, plasterboard or foundations, the more it costs to put right, and almost none of that damage shows itself while it's still small:
- Framing timber takes on water quietly, with nothing visible from the room itself A bearer or stud can already need attention while everything painted or plastered nearby still looks completely normal.
- The bill keeps compounding for as long as the fault runs unaddressed Two or three quarters of unexplained increases can quietly add up to a genuinely awkward number before anyone stops to properly investigate.
- A small fitting swap now beats a full section replacement later A pinhole dealt with early stays a contained job, while the identical fault ignored for years usually spreads to the pipe around it too.

Pinpointed, then shown to you
Zone isolation and listening equipment work together until a specific fitting or short length of pipe is confirmed, with the finding explained clearly before anything gets opened up.
- 04

Why choose Your Plumber Narraweena
Fixed prices, kept
Every job is priced upfront in plain writing before any work starts, the invoice always matches that number, and weekend or late-evening timing changes nothing, because overtime rates simply don't exist here.
Licensed and insured
Your Plumber Narraweena works under licence #275278C with full insurance behind every job, and the compliance certificates that protect your home's paperwork trail arrive with the invoice, without you ever needing to ask for them.
Lifetime Labour Warranty
Workmanship here is guaranteed for life under our Lifetime Labour Warranty rather than for a warranty card's fine-print window, which says more about how the work is done in the first place than any advertisement could.
Genuinely local response
We work these streets constantly rather than commuting in from across Sydney, so the van reaching you has usually just left a job nearby, stocked for the faults the local houses actually develop.
A confirmed pinhole occasionally escalates into full burst pipes territory rather than staying a small fix, and where roots turn out to be involved, blocked drains work usually runs at the same visit. Browse plumbing for everything else.
Where we work
Areas we service
Leak detection reaches Dee Why, Cromer, Beacon Hill, Collaroy Plateau and Brookvale too, using identical equipment and pricing regardless of a property's age or its position on the slope.
Good questions, straight answers
Leak detection questions Narraweena locals ask
Our water bill has climbed for two quarters running and nothing looks wet anywhere. Worth calling?
Definitely worth it, water can be escaping beneath a floor or inside a wall for a long stretch before anything looks even slightly off, so that climbing bill might genuinely be the only warning you get.
Can corroded galvanised pipe genuinely cause a leak, or does it just restrict flow?
Both, actually, the same internal corrosion that chokes pressure over time eventually pits right through the pipe wall, and testing built to trace leaks picks up either version of the problem.
We're renting through Housing NSW. Who actually organises a leak check if the bill jumps?
Either party can raise it, though a tenant flagging a sudden increase early usually gets the fastest result, and any fault found gets reported clearly enough for a landlord to act on.
Does the slope of the block change where an underground leak actually shows up?
It does, water travels with the fall rather than pooling politely near its source, so on a sloped property the wet patch can sit well away from where the pipe actually failed.
Would tree roots be a leak problem or strictly a blocked-drain problem?
Mostly a blocked-drain issue, roots generally crowd a pipe rather than puncture it, though a joint they've already cracked can occasionally weep too, so both get ruled out during the same visit.
A leak got fixed here last year and something similar seems to be happening again. Full retest needed?
Not usually, the earlier finding gives us a head start on where to look, and testing normally confirms quickly whether it's a repeat of the same fitting or a genuinely new fault.
