We service pool automation systems across Melbourne with a practical focus on pH probes, ORP probes, dosing pumps, and controller logic. If the system is drifting, overdosing acid, underfeeding chlorine, or showing readings that do not match the real water balance, we inspect the setup carefully and bring it back to consistent daily control.
If the controller display looks correct but the pool still drifts out of range, the system needs a proper check rather than another quick menu adjustment. A probe can accept calibration values and still drift badly a few days later. A dosing pump can sound normal and still feed the wrong volume because of worn tubing, prime loss, air leaks or partial blockage. An ORP value can also look steady while the sample stream is weak or the sensor is fouled.
That is why we treat automation as a complete measuring-and-dosing loop. The measuring side, the chemical feed side and the system response all have to be checked together before the settings can be relied on. Where possible, we compare controller readings with independent water testing so the setup is not judged by the display alone.
We often see this after startup periods, in pools with ongoing aeration, or where acid feed is technically running but the injection point, mixing pattern or actual pump output is not delivering the correction the controller expects.
ORP is not a full substitute for understanding chlorine performance. pH, stabiliser level, contamination load, probe cleanliness and sensor response time all affect how useful that ORP number really is.
This may come from repeated short feed cycles, poor control logic, probe drift, wrong pump assumptions, false low readings or a controller reacting to noise instead of genuine demand.
That usually means it was installed but not truly commissioned. Good automation should reduce weekly guesswork, not create a second layer of confusion over already unstable water balance.
We use a step-by-step check because automation problems often come from several small faults stacked together. A slightly dirty probe, a weak sample stream and an over-aggressive dosing window can each seem minor on their own. Together they produce unstable control. Our job is to separate those layers and tune the system so the settings can be reviewed later without guesswork.
We start by checking whether the automation is reading from a reliable starting point. If the controller view is already detached from current water conditions, the rest of the settings cannot be trusted until that gap is understood.
We do not treat “it calibrates” as proof the probe is healthy. We look at how stable the probe is, how quickly it responds, whether fouling or age is affecting it, and whether it is suitable to keep as a control input.
We check whether the dosing pump is actually moving the volume the controller assumes, whether prime is reliable, whether tubing and injection hardware are sound, and whether chemical feed is physically reaching the water the way it should.
We review target values, feed windows, delay settings, lockouts and anti-hunt behaviour so the system does not bounce, chase noise or overcorrect after every small fluctuation.
We leave the automation with settings that are realistic for the pool, the season and the hardware condition. The aim is consistent daily control over time, not a one-day perfect reading that collapses as soon as the load changes.
Throwing more acid or chlorine at an unstable automation system usually hides the fault for a short time and then makes the operating picture harder to read. If the sensor is drifting, if the sample water is misleading, or if the pump is not feeding what the controller assumes, the pool can move in and out of range without the owner understanding why. That leads to recurring call-outs, wasted chemical and false confidence in the display.
This service is most useful for residential pools with automation already installed, new builds after handover, family pools with regular load changes, and pools where pH rise or sanitiser instability keeps returning despite previous adjustments. It is also valuable after replacing a controller, dosing pump, chlorinator, plumbing section or probe set, because even a correct repair can change how the control system behaves.
Yes. Many visits involve existing systems that were installed elsewhere and now need commissioning, probe review, dosing checks or recovery after unstable control.
No. ORP is useful as one control signal, but it is not the whole picture. Probe condition, pH, stabiliser, contamination load and water movement all influence how meaningful that value is.
They do. A controller may assume a feed volume the real pump is no longer delivering because of tube wear, prime loss, air leaks, check-valve issues or injection blockage. Menu settings alone do not confirm chemical delivery.
Review is sensible when readings become less believable, chemical use changes unexpectedly, a probe ages, hardware is replaced, the pool comes out of startup conditions or the system needs more manual correction than it should.
If your pool automation is drifting, overdosing, underfeeding or no longer behaving like a reliable control system, Litra Pool Care can inspect the setup, check the hardware and tune the logic so the pool is easier to monitor and adjust.
We service pH and ORP automation, dosing pumps, controller settings and post-installation commissioning across Melbourne, with a practical focus on consistent performance rather than screen readings alone.
