What we do
Find the real cause before anything is replaced
Most pool problems get fixed by replacing whatever the previous contractor blamed. New pump, new filter, new motor, same problem. The water still drops, the suction is still weak, the bubbles are still there.
Skynet Pools approaches it differently. We diagnose first, replace second. Pressure tests, vacuum tests, dye tests and a thorough pump room inspection tell us exactly where the suction problem is, so the repair is targeted and the fault stays fixed.
Our suction diagnosis crews work across Pretoria East, Centurion, Waterkloof, Lynnwood, Menlyn, Garsfontein, Wapadrand, Mooikloof and the surrounding suburbs.

Why diagnose first
Why a proper diagnosis saves money
Six reasons Pretoria homeowners ask Skynet Pools to diagnose their suction problem before any contractor swaps parts.
Stop wasted spending
A proper diagnosis stops you from paying for a new pump when the real fault is a R200 union on the suction line.
Real fault finding
Pressure tests, vacuum tests and dye tests pinpoint the actual problem instead of guessing or replacing parts at random.
Track down leaks
Suction-side leaks pull water out of the pool while the pump runs, often invisible. We find them before they get worse.
Protect the pump
Air leaks and starving pumps destroy seals and motors fast. Diagnosis stops a R500 fix becoming a R10000 replacement.
Written quote
Once we find the cause, you get a written, itemised quote for the repair. No mystery charges, no upsell.
Honest advice
If a part is fine, we say so. If it is failing, we say that too. Honest fault finding from techs who do this every week.
Our process
How we diagnose your suction problem
A clear path from first call-out to a written quote you can actually trust.
- 01
Listen to the symptoms
We start by listening. When did it start, what does it look like, what has been changed recently. Symptoms point us at the right tests.
- 02
Visual inspection
Pump room, pool, skimmer, weir, returns, lines and timer all checked visually for the obvious culprits before any tests start.
- 03
Pump and basket check
Pump basket, lid o-ring, multiport valve and impeller checked for blockages, perished seals, leaks and worn parts.
- 04
Pressure and vacuum tests
Suction and return lines are isolated and pressure or vacuum tested to confirm whether the fault is in the buried plumbing.
- 05
Dye and flow tests
Where needed we use dye and flow tests to identify weak skimmer suction, blocked main drain or back-flow through valves.
- 06
Written diagnosis
You get a written diagnosis with the exact cause, what needs to be repaired or replaced, and a fixed-price quote for the fix.
Faults we find
Common pool suction problems we diagnose
Different symptoms point to different causes. Here are the suction problems we find most often in Pretoria pools.
Air in the pump basket
Almost always an air leak on the suction side. We isolate which fitting, lid, o-ring or pipe is letting it in.
Pump that will not prime
Caused by air leaks, low water level, blocked baskets, failed o-rings or a damaged impeller. Tested in order.
Weak skimmer suction
Blocked skimmer line, partially closed valve, weak pump or back-pressure from a clogged filter, properly diagnosed.
Pool losing water
Suction-side leaks pull water out only while running. Return-side leaks drip while running. We test both.
Vacuum will not work
Caused by suction loss, blocked lines, failed weirs or worn vacuum hose o-rings. Each tested in turn.
Noisy or vibrating pump
Cavitation from air or starvation, debris in impeller, failing bearings, all checked before we replace anything.
How we test
Real tests, not guesswork
Pool plumbing is mostly buried, so the only way to find the fault is to test. We use the right tools and a logical sequence so the diagnosis is properly evidenced.
Pressure testing
Lines are isolated and pressurised so we can see exactly where pressure drops and how fast.
Vacuum testing
Suction lines are placed under vacuum to mimic running conditions and reveal hidden air leaks.
Dye testing
Coloured dye reveals weeping cracks, weak skimmer flow and back-flow through valves under live operation.

Frequently asked
Suction problem questions, answered
The questions Pretoria homeowners ask us most before booking a suction diagnosis.
What causes weak pool suction?
The most common causes are blocked skimmer or pump baskets, low water level, a clogged filter, air leaks on the suction side, broken suction lines or a tired pump impeller. We diagnose which one is yours before quoting any repair.
How long does suction diagnosis take in Pretoria?
A standard suction diagnosis takes 1 to 2 hours on site. Complex faults that need pressure testing or excavation to find a buried leak may take a full day. We confirm scope before we start.
How much does suction problem diagnosis cost?
Pricing depends on whether the fault is at the pump, in the pool or in the buried plumbing. After a free site visit we quote in writing so you know what the diagnosis will cost before we start any work.
My pump is making air bubbles, what does that mean?
Bubbles in the pump basket usually mean an air leak on the suction side. It can be a low water level, a loose lid, a perished o-ring, a cracked union or a leaking suction pipe. We test each one to find the exact cause.
Can a leaking suction line cause my pool to lose water?
Yes. A leaking suction line can pull air in while the pump runs and slowly leak water out when the pump is off. We pressure test suction lines to find any leak before recommending repair.
Will you fix the problem on the same day?
Often yes. Simple suction problems are diagnosed and fixed in one visit. More complex faults are diagnosed first and quoted, with the repair scheduled as a follow-up visit so the right parts are on hand.
Can you fix faults left behind by another contractor?
Yes. We regularly diagnose pools where multiple parts have been swapped without solving the issue. Fresh eyes, proper testing and an honest answer about what was actually wrong.
