Pool & spa leak detection — Mornington Peninsula

Is your pool losing water? We'll find exactly where from.

Pools naturally evaporate, but persistent water loss means a leak. We locate the exact source — shell, fittings, skimmer, plumbing or equipment — without draining or causing damage.

Evaporation vs leak

How to tell if your pool is actually leaking

Every pool loses some water to evaporation — typically around 3–7mm per week depending on weather and sun exposure. But if you're adding more than that regularly, or noticing the water level dropping faster on some days than others, you may have a leak.

A simple bucket test can confirm it: fill a bucket with pool water, place it on the pool step, and mark both water levels. Leave for 24 hours without the pump running. If the pool loses significantly more water than the bucket, the difference is a leak — not evaporation.

Don't ignore a pool leak

Even a small pool leak wastes thousands of litres per week, adds to your water bill, and can cause soil erosion and structural damage around the pool shell. The longer a leak runs, the more expensive the problem becomes.

Signs you have a pool leak

What to look out for

🌊 Water level dropping more than 7mm per day
💧 Wet or soggy ground around the pool
🌿 Unusually green or lush lawn near the pool
🔄 Auto-fill running constantly
🧪 Needing to add chemicals more frequently
🏗️ Cracks or movement in the pool surround
💦 Pump losing prime
📉 Higher than normal water bills

Where pool leaks happen

We check every possible source

🏊

Pool shell

Cracks in concrete, fibreglass or tiled shells — including stress cracks, surface cracks and structural cracks that allow water to escape.

🔩

Fittings & penetrations

Skimmer boxes, return jets, light fittings, main drains and any other penetrations through the pool shell are common leak points as seals age.

🔧

Plumbing & pipework

Underground pipes connecting the pool to the pump, filter and equipment can crack, joint-fail or separate — particularly in older pools or after ground movement.

⚙️

Equipment & fittings

Pump housing, filter connections, valves and backwash lines can all develop leaks — often visible at the equipment but sometimes only when pressure tested.

ℹ️

Pool leak detection without draining

In most cases we can locate a pool leak with the pool full of water — using dye testing, pressure testing and specialist listening equipment. Draining a pool is expensive, risks shell damage, and is rarely necessary for detection.

Common questions

Pool leak detection FAQs

Do I need to drain my pool for leak detection?

In most cases, no. We use non-invasive detection methods — dye testing, pressure testing and acoustic equipment — that work with the pool full. Draining is only necessary in rare circumstances and we'll tell you upfront if that's the case.

How long does pool leak detection take?

A typical residential pool inspection takes 2–3 hours depending on the size of the pool, the number of fittings and the complexity of the plumbing. We'll give you a time estimate when you book.

Will you repair the leak?

We're a detection specialist, not a pool repair service. Once we've located and documented the leak, you'll need a pool repairer or plumber to carry out the fix. We'll provide a clear report of what was found and where, so the repair is targeted and efficient.

My pool is losing water but only when the pump runs — what does that mean?

If water loss only occurs when the pump is running (on-pressure), it's almost certainly a plumbing or equipment leak rather than a shell leak. This is actually good news — it's usually easier to locate and repair.
