Is your Centurion pool leaking? Signs, and a free test you can do today

A Highveld summer can empty a pool by a few centimetres a week through evaporation alone, so a falling level doesn’t always mean a leak. These signs usually do.

The level drops faster than the weather explains, week after week.
The water falls and then stops at the same height every time.
The level keeps falling right down to the bottom.
The pump loses prime, sucks air or runs noisily.
The lawn is soggy, the paving has sunk or cracked, or there are wet patches near the pool or pump room.
Your water bill rises because you keep topping up.
The area around the skimmer, light or returns is stained or damp.

Why the stopping height matters. If the water always stops at one height, the leak is usually at that height. A crack in the wall, the skimmer throat, a light niche or a return fitting are the usual suspects. If it keeps falling to the floor, the problem is lower down, in the floor, in a deep wall or in the plumbing.

The bucket test: leak or evaporation?

Evaporation takes water from your pool and from a bucket alike. A leak only takes it from the pool. This free test, done on a calm day, separates the two.

Fill a bucket with pool water to about 5 cm and stand it on the top step so it is partly under water.
Mark the water level inside the bucket, then mark the pool level on the outside of the same bucket.
Leave the pump running as normal for 24 hours. Don’t swim, backwash or top up.
Compare. If the pool has dropped further than the water in the bucket, the pool is leaking.
Repeat with the pump switched off. A bigger loss with the pump on points to the plumbing. A bigger loss with it off points to the shell, skimmer or fittings.

Also check your municipal water meter. If it keeps turning with every tap closed, there is a leak somewhere on the property.

To make your findings even more useful, note the pool level each morning for a week by marking the tile. Photos of those marks help us narrow down where to look, and you can send them on WhatsApp for a first opinion.

What to do right now if your pool is losing water

A few sensible steps protect your equipment and your property while you wait for an assessment.

Don’t let the pump run dry. If the water has dropped below the skimmer opening, switch the pump off at the board. A pump running without water can be damaged within minutes.
Keep the level high enough for the skimmer to work, and note how much water you add each time. Those figures help us estimate the size of the loss.
Don’t drain the pool to look for the leak. An empty concrete pool can be pushed up or cracked by groundwater pressure, and you lose the water you have just paid for.
Look around the pool. Check for wet patches, soft lawn, sunken or cracked paving and damp walls in the pump room.
Keep people and pets away from soft or sinking ground until it has been checked.
Stay clear of electrical equipment if it is wet. If water is pooling around the pump or lighting, switch off at the distribution board only if you can do so safely, and call an electrician.
Take photos and notes. Record the date, the level and any damp areas. It makes the assessment faster and the diagnosis more accurate.

Then get in touch. The sooner we find where the water is going, the less of it reaches the ground, and the less it costs you.

Pool leaks we find and repair in Centurion

Water can escape from five places. Each one behaves differently, so each needs a different fix.

Leaks in the pool shell

Cracks in the floor or walls, failed joints and worn-out areas of the shell can all let water through. A shell leak often shows as a level that falls steadily and keeps falling. We locate the exact point, repair the concrete and, where the shell is moving, lock it together with steel before anything is sealed.

Skimmer, weir and return fittings

Where a fitting passes through the pool wall is one of the commonest weak spots. Over the years the joint between the fitting and the concrete can open, and the level then drops to that height and stops. We re-seal these joints or replace the weir, skimmer or return with a precision-moulded fitting designed for a leak-free connection through concrete.

Light niches

The niche around an underwater light is another classic stopping height. We repair and re-seal the niche and its surround. Electrical faults are a job for a registered electrician, and we will tell you when that is what the fault needs.

Underground pipework

Suction and return lines run beneath the paving, where a leak is invisible until the ground turns soggy or the pump starts sucking air. We trace the line, isolate the section that is losing water and repair or replace it.

Leaks at the pump and filter

Unions, lid seals, valves and pump housings drip and weep as they age. Because these leaks sit above ground, they are often the quickest to fix, and the loss they cause is frequently larger than it looks.

If you aren’t sure which of these applies to you, the bucket test above is a good first step, and a free assessment will settle it.

Pool crack repair in Centurion: steel stitching that stays put

Not every crack is serious, and not every serious crack looks it. Knowing which one you have saves money.

Hairline cracks or structural cracks?

Surface crazing is a network of fine, shallow lines in the plaster. It looks untidy but isn’t moving. Structural cracks run deeper, are often straight and can be felt with a fingernail or a coin. They can widen over time and are the ones that let water out. If you aren’t sure which you have, send us a photo.

Why a patch or paint doesn't hold

A structural crack is a sign the shell is moving. Fill it with plaster or paint over it, and the next movement splits the patch along the same line. The crack returns, usually within a season, and you have paid for the repair twice.

How steel stitching works

We cut channels across the crack at intervals and set heavy-duty steel staples into them with high-tensile resin. The staples tie the two sides of the fracture back into one solid unit, so the load that was tearing the crack open is carried by steel instead. The crack channel is then sealed and the surface made good.

The result is a repair that moves with the structure instead of fighting it, which is why it holds where a rigid patch fails.

Where we use it

Floor and wall cracks that are losing water
Cracks around steps, skimmer positions and the pool corners
Fractures in pools sitting on moving clay
Pools where an earlier patch has already failed

An honest limit

Stitching repairs the pool shell. It cannot stabilise the ground underneath. If your pool has a number of cracks, a worn surface and recurring problems, a full restoration may serve you better, and we will say so plainly. It is covered on our page about pool renovations in Centurion.

Pool pump, filter and equipment repairs in Centurion

When the equipment misbehaves, the pool pays for it in cloudy water, a struggling cleaner and an electricity bill that climbs. These are the faults we are called out for most, and what usually lies behind them.

The pump loses prime or sucks air. Air in the system almost always means a leak on the suction side, in a union, a lid seal or the pipe running to the pump. Replacing the pump won’t cure it. Repairing the leak will.
The pump is noisy or vibrating. Worn bearings, a blocked impeller or cavitation caused by restricted flow are the usual reasons.
Sand appears on the pool floor. The filter’s internal parts, such as the laterals, or the multiport valve have failed and are letting sand through.
The cleaner stops after a few minutes, or pipes pop apart when the pump switches off. Blocked baskets, low flow or a pressure surge from a faulty valve can be responsible.
The chlorinator isn’t producing, or the water won’t stay clear. Cell, control or flow faults can all be the cause.
The timer or controller no longer switches on time.

Repair or replace?

We diagnose first, then tell you honestly whether a repair is worth it. A pump or filter that is simply worn out costs more to keep alive than to replace. In that case we supply and fit a modern, efficient replacement. See our smart pool systems and filtration and hydraulics pages for what we fit.

Electrical faults, such as a dead light cable or a tripping board, belong with a registered electrician. We will point you in the right direction rather than guess.

Why a leaking pool matters more in Centurion

In most places, a leaking pool costs you water and chemicals. In Centurion it can cost you more, because of what lies under the ground.

The dolomite factor

Large parts of Centurion are underlain by dolomite, a rock that dissolves slowly in water and forms cavities. A University of Pretoria study recorded 119 sinkholes in the Centurion CBD area since the early 1970s. Geoscience researchers presenting at the University of Pretoria have stated that sinkholes in Tshwane are caused by water getting into the ground, through leaking pipes and poorly managed stormwater. Engineers who investigated a large sinkhole in Lyttelton Manor described it as one of the biggest in the Centurion area in 25 years.

A University of Pretoria engineering professor has urged Centurion homeowners to treat leaks as urgent.

A pool isn’t a municipal pipe, but it holds many thousands of litres. When its shell or plumbing leaks, that water ends up in the ground beside your home. On dolomite, that is water you don’t want going anywhere you can’t see. Dolomite also varies greatly over short distances, so your neighbour’s ground may not match yours, and the only safe approach is to fix leaks promptly.

Clay adds its own pressure

In suburbs such as Wierda Park, Eldoraigne and Rooihuiskraal, heavy clay swells and shrinks with the seasons. That movement is a common reason pool shells crack in the first place, and a crack that is left to leak makes the ground around it wetter and less stable.

What to watch for

Look for sunken or cracked paving, soft or wet ground, new gaps between the coping and the paving, and a pool that suddenly loses water faster than before. These are reasons to act quickly.

When it is more than a pool problem

If you see a hole, a collapse or ground that is visibly sinking, keep people and pets away and call the municipality and a geotechnical engineer. We repair pools. We are not geotechnical engineers, and we will say so, then work alongside the specialist you appoint.

How a Crispy Pools repair works, step by step

Finding a leak is detective work, and a good repair follows a method. This is ours.

You describe the symptoms. Tell us what you’ve seen and send photos, the bucket test result and any level notes you have. It often narrows things down before we arrive.
On-site assessment. We inspect the shell, fittings, pump room, plumbing and the ground around the pool.
We locate the source. We work by elimination, isolating one part of the system at a time, such as the skimmer, returns, light, shell, pipework and pump side, and checking how the loss behaves. When the water stops falling in one section, we know where to look.
We explain and quote. You get the cause in plain English and a written quote for the fix, before any work starts.
We repair. That may mean re-sealing or replacing a fitting, repairing pipework, stitching a crack with steel or fixing the pump side. If the repair means lowering or emptying the pool, we plan it around the weather and the ground, and explain the options for your water.
We re-test. The job isn’t done until the level holds. We check that the loss has stopped.
We tell you what to watch. You leave knowing what we found, what we did and what to keep an eye on.

Chris leads the work on site. The person who diagnoses your pool is the one accountable for fixing it.

When a repair is enough, and what it costs

A repair is the right answer when

The pool is basically sound and one thing has failed: a single leaking fitting, an isolated crack, a faulty pump, a damaged pipe. Fix that one thing properly and the pool carries on for years. We will say so when that is the case, and we won’t sell you more than the pool needs.

A repair is not enough when

The shell has several cracks, the surface is worn or hollow, or you have already paid for the same pool to be fixed more than once. At that point the repairs are treating symptoms of a tired shell. A full restoration, with a new lining or surface on a strengthened shell, usually works out better value than another patch. Our page on renovating your Centurion pool explains what that involves.

What affects the cost of a repair

Repair prices vary because faults vary. The main factors are:

What has failed and how big the fault is. A weeping union costs far less to fix than a crack in a deep floor.
How hard it is to find. A leak that shows itself at the pump takes minutes. One hiding in underground pipework or a deep wall can take longer to locate.
Access. Pipework beneath paving or behind landscaping takes more work to reach.
Whether the pool needs to be lowered or emptied to reach the fault.
Materials and equipment. Steel stitching, replacement fittings and new pumps all carry their own cost.
Site conditions, such as estate access rules.

A free assessment ends the guesswork. You receive the cause, the fix and a written quote before any work starts.

Waiting rarely helps. A leak wastes more water the longer it runs, it can raise your water bill, and in Centurion it keeps feeding water into ground you would rather keep dry.

Why Centurion homeowners call Crispy Pools for repairs

Not every equipment problem requires replacement. We inspect the existing equipment and identify the component responsible for the fault.

An honest diagnosis

We tell you what is wrong, what it needs and, just as importantly, what it doesn’t need. If a small fix will do, that is what we recommend.

Chris is on site.

He brings 15+ years of trade construction experience, so ground movement, concrete and plumbing are understood in practice. The person who finds the fault is the person accountable for fixing it.

We repair the cause.

Cracks are locked with steel staples rather than filled, fittings are re-sealed or replaced properly and pipework is traced and repaired, so the fault stays fixed.

We are estate-ready.

We work within the access, security, contractor registration and noise rules of Centurion’s estates, including Midstream, Irene, Southdowns and Copperleaf.

Written warranty

Every project carries a written workmanship warranty. Ask Chris to walk you through exactly what it covers before you decide.

Pool repairs in Centurion: your questions answered

How do I know whether my pool is leaking or just evaporating?

Run the bucket test described above. If the pool drops further than the water in the bucket, it is leaking. Evaporation affects both equally.

How much does a pool repair cost in Centurion?

It depends on what has failed, how hard it is to reach and how long it takes to locate. A weeping union costs far less than a crack in a deep floor. The cost section above explains the factors, and a free assessment gives you a written quote before any work starts.

How long does a pool repair take?

Simple above-ground fixes at the pump and filter are the quickest. Shell, fitting and underground repairs take longer, and your written quote states the timeline for your pool.

Can you find a leak without draining the pool?

Usually, yes. Most diagnosis is done with the pool full, because that is how the leak behaves. We lower or empty the pool only when the repair itself requires it.

Can I keep swimming in a leaking pool?

Yes, as long as the level stays high enough for the skimmer to work and the water stays clean. Switch the pump off if the level drops below the skimmer, because a pump running dry can be damaged quickly.

Why does my pump keep losing prime?

Air getting into the system is the usual cause, and that normally means a leak on the suction side, such as a union, a lid seal or the pipe leading to the pump. We trace the leak and fix it, which solves the problem more reliably than replacing the pump.
