Pool Leak Detection & Repair Singapore — Find the Source, Fix It Right
A leaking pool wastes water, drives up your bills, and quietly damages the surrounding structure. We find where the leak is coming from and repair it properly.
Singapore's Pool Leak Detection Specialists
Pool leaks are more common than most owners realise. The problem is that many leaks are hidden. You may not see water running out anywhere, but your pool is slowly losing water every day.
At Infinity Pool Services, we use professional detection tools to locate leaks without tearing apart your pool unnecessarily. Once we find the source, we carry out the repair work in the same visit where possible.
We work with private homeowners, condominium management teams, and penthouse clients across Singapore. If your pool is losing water and you do not know why, we will find out.
Signs Your Pool May Have a Leak
Many pool leaks go undetected for months because the symptoms look like normal pool behaviour. Here is what to watch for.
Your Pool Needs Topping Up More Than Twice a Week
Some water loss from evaporation is normal in Singapore's heat. Losing more than 2 to 3 cm of water per week is not. If you are constantly refilling, something is wrong.
Wet or Soft Ground Around the Pool Area
Damp soil, soft patches in the garden, or wet concrete near the pool edge are signs that water is escaping underground. This often points to a plumbing or structural leak.
Visible Cracks in the Pool Shell
Hairline cracks in the walls or floor of the pool can allow water to seep through slowly. These are easy to miss during normal use but become obvious when the pool is drained.
Tiles or Grout Popping Off Without Obvious Impact
When water gets behind tiles through a failed waterproofing layer, it creates pressure that pushes tiles off the wall. If tiles are detaching for no clear reason, water ingress is likely the cause. Our Pool Repair & Renovation page covers this in more detail.
Water Bill Going Up with No Change in Usage
A sudden increase in your PUB water bill is one of the clearest signs of a leak. If your pool equipment is running normally and usage has not changed, water is escaping somewhere.
Air Bubbles in the Return Jets
Bubbles coming out of the return jets when the pump is running suggest air is entering the plumbing system. This usually indicates a suction-side leak in the pipes or fittings.
Pool Equipment Running Constantly
If your pump is working overtime trying to maintain water pressure and circulation, there may be a pressure drop caused by a plumbing leak.
Where Pool Leaks Typically Occur
Understanding where leaks come from helps explain why professional detection equipment is needed. Leaks rarely happen in one obvious place.
Pool Shell and Structure
Cracks in the concrete or fibreglass shell allow water to seep directly into the ground. These are structural leaks and require proper crack injection or patching before any cosmetic repair is done.
Underground Plumbing
The pipework running under and around your pool carries water to and from the pump, filter, and returns. A break or joint failure in these pipes can cause significant water loss that is invisible from the surface. Our team uses pressure testing to isolate which pipe section is failing.
Pool Fittings and Penetrations
Skimmers, main drains, return jets, and light fittings all penetrate the pool shell. The sealant around each fitting degrades over time, especially in Singapore's heat. These penetration points are a common source of leaks in pools that are 5 years old or more.
Pump and Filter Equipment
Worn seals, cracked valve bodies, and loose fittings around the pump and filter housing can all allow water to leak at the equipment pad. This is often visible as damp ground or wet marks near the plant room. See our Swimming Pool Plumbing Repair page for related work.
Waterproofing Membrane
When the waterproofing layer beneath the tiles breaks down, water moves through the tile surface and escapes into the pool structure. This type of leak is slow but causes significant tile and structural damage over time. Our Pool Waterproofing page explains how this is addressed.
Our Pool Leak Detection & Repair Process
We follow a structured process to make sure we find every leak, not just the obvious ones.
Free Site Inspection
We start by visiting your property for a full visual inspection. We look at the pool structure, equipment, surrounding ground, and water level behaviour before using any detection tools.
Bucket Test (Evaporation Baseline)
If needed, we run a simple bucket test to separate normal evaporation from actual water loss. This gives us a baseline before we start technical detection.
Pressure Testing the Plumbing Lines
We isolate each plumbing line and pressure test it to identify any pipe or fitting that is losing pressure. This tells us exactly which section of underground plumbing has a fault.
Dye Testing Around Fittings and Cracks
We use dye injection around suspected leak points including skimmers, return jets, main drains, and visible cracks. If dye is pulled into a gap, there is a leak at that point.
Acoustic and Thermal Detection
For leaks that are not visible at the surface, we use acoustic listening equipment and thermal imaging to trace the path of escaping water through the pool structure and underground.
Written Leak Report
Before any repair work begins, we give you a clear report of what we found, where the leaks are, and what repair work is required. You know exactly what is happening before any costs are committed.
Leak Repair
We carry out the repairs using the correct method for each type of leak. Structural cracks are injected or patched. Failed fittings are resealed or replaced. Plumbing breaks are accessed and repaired with minimal disruption. Waterproofing failures are referred to a full re-waterproofing scope if required.
Post-Repair Water Level Check
After repairs, we monitor the water level to confirm the leak has been resolved. We do not consider the job done until the pool is holding water properly.
Types of Pools We Handle

Landed Home Pools
Private pools in bungalows and semi-detached homes are the most common source of plumbing and structural leaks we attend to. Ground movement, root intrusion, and aging pipes all contribute to leaks in older landed properties.

Condominium Pools
Leaks in condo pools need careful investigation because they can affect basement structures and neighbouring units. We coordinate directly with MCST management, document all findings, and carry out repairs to the standards required for common property.

Penthouse and Rooftop Pools
A leak in a rooftop or penthouse pool is an urgent matter. Water escaping at height can cause serious damage to the floors below. We treat these as priority jobs and carry out waterproofing verification as part of every penthouse pool leak repair.
Our Workmanship Guarantee
All leak repair work we carry out is covered by a workmanship guarantee. If a repair we completed fails within the warranty period due to our workmanship, we return and fix it at no charge.
We use proper repair materials matched to each type of leak. We do not apply temporary patches and call it done. Our goal is to fix the leak so it does not come back.

Frequently Asked Questions: Pool Leak Detection & Repair Singapore
How do I know if my pool has a leak or if it is just evaporation?
A simple bucket test helps answer this. Place a bucket of water on your pool step, fill it to the same level as the pool, and check both after 24 hours without using the pool. If the pool drops more than the bucket, you have a leak. Normal evaporation in Singapore accounts for roughly 2 to 5 mm of water loss per day.
How long does pool leak detection take?
A standard leak detection visit takes 2 to 4 hours depending on the pool size and the complexity of the plumbing system. If the leak is straightforward, we may be able to carry out the repair the same day.
How much does pool leak detection cost in Singapore?
Professional pool leak detection in Singapore typically starts from SGD 150 to SGD 450 for the detection work. Repair costs are separate and depend on the type and location of the leak. We provide a full written quote before any repair work begins.
Can you fix a pool leak without draining the pool?
Some leaks around fittings, skimmers, and equipment can be repaired without draining the pool. Structural cracks and plumbing breaks usually require a partial or full drain to prepare and repair the surface properly.
What happens if a pool leak is left untreated?
Untreated leaks cause progressive structural damage. Water escaping into the surrounding soil weakens the ground beneath the pool. Tiles detach, the shell can crack further, and surrounding landscaping or building structures can be affected. The repair cost grows significantly the longer a leak is left.
Do you detect leaks in rooftop and penthouse pools?
Yes. We take rooftop and penthouse pool leaks seriously because water escaping at height can damage the floors below. We carry out a full structural and waterproofing assessment as part of any penthouse pool leak inspection.
Can a pool leak affect my condominium neighbours?
It can, particularly in older condo developments where the pool deck sits above habitable space. Water escaping through a structural crack or failed waterproofing membrane can seep into the ceiling of units below. We work with MCST management teams to handle these cases properly.
What tools do you use to detect pool leaks?
We use pressure testing equipment for plumbing lines, dye testing for fittings and cracks, acoustic listening devices for underground pipe faults, and thermal imaging cameras for temperature anomalies behind pool surfaces. All methods are non-invasive.
Is the detection fee separate from the repair fee?
Yes. We charge for the detection and diagnostic work separately from any repair work. You receive a written report first, then a separate quote for repairs. You are not committed to the repair just because you booked the detection.
How soon can you come to inspect my pool?
Contact us and we will arrange a visit as soon as possible. For urgent cases where a penthouse or condo pool is actively losing water and affecting other areas, we prioritise the inspection.
