Before anyone can find your leak, someone has to work out which of your three water systems it's coming from — because they behave completely differently, and searching the wrong one wastes the whole visit.
Pressurised supply is under constant pressure. It leaks continuously, twenty-four hours a day, whether anyone is home or not, and it makes noise doing it.
Waste and drainage carries no pressure at all. It only leaks when something is being used — a shower running, a washing machine emptying, a toilet flushed. Twelve seconds of water, then nothing until the next time.
Heating pipework is a closed, pressurised circuit that leaks continuously but is only under full pressure and temperature when the system is running.
Those three produce entirely different evidence.
Damp that's constant and unchanging is supply. Damp that worsens after someone showers is waste. A heating system that keeps losing pressure and needing topping up is the third — and it isn't a plumbing leak at all in the sense most people mean.
Tap the call button and tell us whether the damp gets worse at particular times. That one answer eliminates a third of the building before anyone arrives.
FlowPoint Plumbing locates and repairs concealed leaks across Clarence, IA for homes and businesses.
Three tests, and you can do all of them before calling.
Shut everything off — no taps, no appliances filling, no toilets flushed, nobody using water.
Read your water meter, including the fine dial or leak indicator. Leave it one to two hours with the property still. Read it again.
Watch the damp patch through a normal day. Does it darken or spread after a shower, after the washing machine empties, after the dishwasher drains, after a particular toilet is flushed?
Check the pressure gauge on your boiler or system. If it drops over days or weeks and needs repressurising repeatedly, the heating circuit is losing water somewhere — pipework in a floor, a radiator valve, or a component within the system.
If test one showed movement, close your main shutoff and repeat it. Still moving? The leak is between the meter and the shutoff — usually underground on the incoming supply, and not inside your building at all.
Wherever the leak is, one rule applies: water emerges where the building lets it, not where it failed.
It leaves the fault, runs along the top of a joist, follows a pipe through a wall, crosses a floor void, and comes through at whatever point gravity and construction allow. The visible damage can sit rooms from the actual failure — different wall, different floor, sometimes a different storey.
Which is why cutting into the visible damage is how people pay for a hole in the ceiling and still have a leak running.
Detection inverts that. The location is established first — non-invasively where possible — and the opening-up is one small, deliberate cut at a known point rather than a series of hopeful ones.
Plasterboard, tiling, flooring, decoration, and a drying period, before a single plumbing fitting has been touched.
You've spent the money and you're still looking.
The detection has a cost. It's routinely less than one wrongly opened ceiling.
Condensation, a failed roof, blocked guttering, penetrating damp, and rising damp all present as an internal damp patch. Establishing whether it's plumbing is part of the job — and if it isn't, we'll tell you rather than charge you to keep looking.
The system determines the method. That's why identifying it first matters so much.
Finding a Supply Leak
Pressurised — it makes noise, constantlyPressurised water escaping through a small opening makes a characteristic sound carrying through pipe, structure, and ground. Ground microphones and pipe-contact sensors trace it to a point. Highly effective — but only on pressurised lines, which is why it's useless on a waste leak.
Sections isolated and pressurised individually, narrowing the search from a building to a run.
A safe gas mixture introduced into a drained line escapes at the fault and rises through the structure to a detector. The method that works where acoustic struggles — plastic pipe, very small leaks, deep or noisy environments.
A hot supply leak creates a warm signature through a floor or wall.
Finding a Waste Leak
No pressure — nothing to hearRunning each fixture individually while watching for the damp to respond. Slow, methodical, and it's what actually works — because there's no pressure to make noise and nothing for acoustic equipment to hear.
Coloured water through a suspect trap, shower tray, or waste connection to confirm which one is passing.
For buried and concealed drainage where the fault is a crack, an open joint, or a displaced section.
Reading actual moisture content across materials to find the wettest point, which sits nearest the source.
Finding a Heating Leak
Closed circuit — hot, and losing pressureIsolating circuits and zones to find which one is losing.
Which is at its most effective here because the water is genuinely hot.
Over floors where pipework runs in screed.
Supply lines in or beneath the slab. Water has nowhere to go but sideways and up, saturating a wide area before appearing. Expensive to reach, which makes precise location worth most here.
Shows on the bill, on the ground, or as pressure loss — and frequently never appears inside at all.
Water enters at a fault and travels down the outside of the pipe, emerging at floor level a storey below.
Running along joists until something stops it, then dropping. The classic case of damage sitting metres from the fault.
Failed tray seals, waste connections, and grout no longer shedding water. Extremely common — and a waste leak, so it only appears when the shower runs.
Pan seals and waste connections passing a small volume with every use.
Reads exactly like a supply leak and isn't.
Behind washing machines, dishwashers, and fridge water lines, out of sight until the cabinet or floor gives it away.
Made once, covered, never inspected again.
Supply, waste, or heating. Acoustic equipment finds a pressurised leak and hears nothing at all on a waste leak — so searching the wrong system wastes the visit.
Constant means supply. Worse after a shower means waste. That single answer eliminates a third of the building.
Because a hole in the wrong place is a cost you keep, and it doesn't help you find the leak.
The stain marks where it emerged. The repair happens where it started.
Condensation, roofing, and penetrating damp all imitate a leak. If that's what we find, you'll be told rather than billed to keep searching.
A repeat meter test after the repair, so you know the system is genuinely tight rather than quieter.

Acoustic equipment finds pressurised supply leaks by the noise escaping water makes — and a waste pipe carries no pressure, so there's nothing to hear. Searching the wrong system with the right tool finds nothing at all.
By whether it changes. A supply leak runs constantly, so the damp is unchanging whether the property is busy or empty. A waste leak only runs when something is being used, so the damp worsens after a shower, a wash cycle, or a particular toilet. Watch it for a day.
Close everything, read the meter, wait one to two hours without using water, and read again. If it moved, water is leaving your system. It's the most useful ten minutes you can spend before calling, and it costs nothing.
That's one of the most reliable indicators of a concealed or underground supply leak. Buried leaks can run for months on the bill alone before any damp appears, which is exactly why the bill is worth taking seriously.
That's a leak on the closed heating circuit rather than on your water supply — pipework in a floor, a radiator valve, or a component in the system. It can produce damp that looks identical to a supply leak, and it needs a different approach.
Frequently not. Water runs along joists and pipe runs before it drops, so the fault can sit metres away — sometimes in another room. The stain marks where it emerged, which is why locating comes before cutting.
That's the point of detection. Acoustic, thermal, moisture mapping, tracer gas, and controlled testing locate the fault so that access, when needed, is one deliberate opening at a known position.
A safe gas mixture introduced into a drained pipe, escaping at the fault and rising through the structure to a detector. It's what works where acoustic detection struggles — plastic pipe, very small leaks, or deep and noisy environments.
It could, and that's a real part of the diagnosis. Condensation dries and stays dry; a leak returns. Roofing faults, blocked gutters, and penetrating damp also imitate plumbing leaks. If it isn't plumbing, we'll say so.
Often a hot supply or heating line leaking beneath. It's one of the more distinctive signs and worth acting on quickly, because sub-floor leaks saturate a wide area before surfacing.
Policies vary, and many distinguish between the leak damage and the cost of accessing the leak. What helps every claim is the same: prompt action, photographs, and a written record of what was found and where. We provide that as standard.
Yes, and it's worth it where there's a history of damp, an unexplained bill, or visible past repairs. Supply and drainage problems are expensive, largely invisible on a standard survey, and far easier to negotiate before you own them.
Supply, waste, or heating. They leak on different schedules, produce different evidence, and need different equipment to find — and the fastest way to waste a detection visit is to search the wrong one thoroughly.
FlowPoint Plumbing identifies the system before anything else, asks whether the damp changes with use, locates the fault with the method that system actually requires, and opens up once at a known point.
