A pool is cleaned on the way round

Cleaning a pool means keeping the water moving and the water right. This page draws the circuit the water runs, from the skimmer out to the pump, the filter and the dosing point and back in at the return, and names what each state's own health, safety and water source says at every turn of it.

General information from state health, safety and building sources, not advice about your pool.

The drawing is the index. Every mark on it opens the guide about that turn. The water carries the reading each health page gives, the store and the drain hang off the loop where they meet it, and each mark rests on a source listed at the foot of its page.

Turn by turn

The circuit below runs in the water's own order. Each turn is a real part of a home pool, and each one carries a rule a source on this site states.

  1. The water

    Three health pages give the readings, and they are not the same figures. SA Health keeps free residual chlorine in a home pool at 1.0 to 3.0 mg/L and the pH between 7.2 and 7.6. Queensland Health's rural-properties page keeps free chlorine at 2 mg/L where the water is under 26 degrees and 3 mg/L above that, with the pH between 7 and 7.6. The Better Health Channel gives a pH between 7 and 7.6 and prints no free chlorine figure at all. The readings guide sets the three side by side and says which page applies where.

  2. The skimmer

    The water leaves the pool here, and this is the part of a home pool that looks like a seat to a child. To a child an uncovered skimmer box looks like a potty or a seat, says a safety alert from Western Australia's Consumer Protection published by Product Safety Australia. A 2009 warning on the same site, from South Australia's consumer affairs office, says the box is connected to the pump, so the suction at it is powerful; it followed an incident in Western Australia in which a four-year-old was gravely injured after sitting on one. Pools and spas with potty-style skimmer boxes and outlets that can trap a person are banned from supply in Australia.

  3. The pump

    Pool water must be regularly circulated and filtered, SA Health's page says, and the pump is what moves it. The suction at the skimmer is the strong side of the same machine, and the cover over the box is the part that has to be adequately secured at all times.

  4. The filter

    SA Health's page says the filter system should pass the whole volume of the pool in six to eight hours, and that it should run continuously while the pool is being used and for at least an hour afterwards. How long a filter needs to run depends on the size of the pool and the pump, the Better Health Channel's page says, and where its page gives no number it says to ask the manufacturer.

  5. The dosing point

    The water is treated on its way back in. WorkSafe Victoria's safety alert, written after an aquatic centre's automatic dosing system mixed pool chlorine and pool acid, says the two chemicals belong in the pool separately, each added to the filtered water as it returns. The same alert describes what the mixing did: an electrical fault stopped the pump, the dosing system added both chemicals into a pipe with no flow, and a toxic chlorine gas formed that injured employees and swimmers.

  6. The return

    The water comes back into the pool here, and the cleaning is what has happened to it in between. A filter that does not operate properly leaves even the right chemicals unable to do their work, SA Health's page says.

The branches off the circuit

Three short marks hang off the loop, and each is a whole guide of its own.

  1. The chemical store

    Swimming pool chemicals can be very dangerous when stored incorrectly, Safe Work Australia's information sheet says, and it sets out which of them should not be stored together. The chemicals guide sets that beside WorkSafe Queensland's answers for pool shops and the isolation rules in WorkSafe Victoria's alert, each named.

  2. Town water

    A pool loses water and is topped up. SA Health says only treated mains water from a domestic water supply should be used to fill a pool, that the top-up should be done with a hand-held hose or bucket, and that all top-up water should be added through the skimmer box with the filtration system running.

  3. Out, with the backwash

    The water that rinses the filter has to go somewhere, and the two sources here do not say the same thing. SA Health's page says that in sewered areas the water used to backwash the filter must always be disposed to sewer. Water Corporation's page for Western Australia says domestic pool and spa backwash is not trade waste and may not be discharged to sewer there, and points to the local council for disposal options. The guide sets each utility's rule out by name.

Five guides, five turns

Each guide redraws the circuit with its own turn at full ink and the rest of the drawing held back, so the position of the page you are reading is always visible.

  1. Guide 1 What should pool water read? Lit on the drawing: the water
  2. Guide 2 The skimmer box, and what it can do to a child Lit on the drawing: the skimmer box
  3. Guide 3 How are pool chlorine and acid stored and handled? Lit on the drawing: the chemical store, and the dosing point
  4. Guide 4 Topping up and emptying: where may the water go? Lit on the drawing: the town water inlet and the way out
  5. Guide 5 What does cleaning a pool actually involve? Lit on the drawing: the pump, the filter and the return
