Your Swimming Pool filter will need to be regularly backwashed to remove the retained particules from the filtration process. Backwashing is the process of reversing the flow of water through the filter which lifts the retained particules from the filter surface and directs the dirty water down the drain and away from the system.

Always backwash the filter after vacuuming the pool or at least on a weekly basis.

NOTE – Make sure heating is switched off and allowed to cool before starting the backwash procedure.

  1. Turn off pump
  2. Turn MULTIPORT handle to backwash position
  3. Open valve on backwash line (if fitted)-  The backwash line is usually to the right of the multiport valve and often has a small sight glass in line
  4. Turn pump on
  5. Leave to run for approx. 60 seconds. There is usually a sight on the MULTIPORT to see when the water runs clear
  6. Turn off pump
  7. Turn MULTIPORT handle to rinse
  8. Turn pump on
  9. Leave to run for approx. 10 seconds
  10. Turn off pump
  11. Turn MULTIPORT handle back to filtration
  12. Turn pump on and recommence filtration
  13. Close valve on backwash line (if fitted)
  14. Turn heating back on once filtration has recommenced

Your pool water needs to be tested on a regular basis. When testing domestic swimming pool water, the most common way of testing is to use a comparator test kit which works by comparing the colours of a known concentration to a sample. Each individual test kit is different but the principal is the same. Fill the tester with water and add the appropriate tablet to the test tube. (do not touch the tablets  as this will give false readings, try to drop tablets straight into test chambers without touching them)

Add DPD 1 for chlorine testing and Phenol Red for PH testing.

Shake the tester until both tablets are dissolved then compare the test with the colour chart.

The ideal range for chlorine is between 1.0 – 3.0 ppm and PH between 7.2 -7.6, this is usually around mid-way on the colour charts and the test should show an orange colour for ideal PH and a mid-pink colour for ideal chlorine.

If the levels are out then small chemical adjustments are required and another test within 18 hours is recommended, when adding chemicals add little and often and re test regularly, this will keep a stable level rather than an erratic variation.

More advanced testing, generally used for commercial swimming pools can be carried out using a photometer which works by passing a beam of light through the water sample and providing an accurate result on a digital display, this form of testing eliminates variations in peoples vision and provides a much more accurate result which is required for commercial operations.

Vacuuming the pool removes dust and debris from the pool floor and is an important part of the regular swimming pool maintenance.

Most pools have built in provision for vacuuming and providing you have good quality well maintained equipment and filtration the vacuuming process is a simple task that should be carried out weekly or fortnightly.

Vacuuming the pool is usually carried out using either a dedicated vac point or by using one of the pool skimmers to create the suction required for vacuuming.

The process is simple and the following guide shows the step by step procedure to vacuum the pool.

        1. Check that the skimmer valve or vac line valve is fully opened and all other suction valves are shut prior to setting up the vac equipment.
        1. Take the vac pole and attach the correct vac head to the pole (Note -only a liner swimming pool vac head should be used on PVC lined swimming pools and not a vac head designed for concrete tiled swimming pools). Lay the pole on the swimming pool surround near to the vac point.
        1. Lay out the vac hose on the swimming pool surround in a straight line and attach one end to the vac head already attached to the pole.
        1. Lift the pole and place the vac head and attached hose into the water, keep hold of the vac pole in one hand and then and then feed the remaining hose into the swimming pool slowly using your other hand, there is a knack to this which takes practise to master but the idea is to feed the hose in slowly to force the air out and water into the hose, continue to feed hose into the swimming pool until water comes out of the open end of the hose.
        1. Once the vac hose is completely filled with water it can be attached to the vac point or skimmer, if the valve is open and the pool pump is running the suction will draw the vac hose into place and vacuuming can commence immediately.
        1. Once attached to the vac point or skimmer the vac head must remain under water at all times to prevent air being drawn into the system which would cause the swimming pool pump to lose prime.
        1. Slowly vacuum the pool. If you vacuum too quickly debris will be pushed into suspension and not sucked up.
        1. If the suction becomes laboured during vacuuming then stop and return to the pool plant room, check the swimming pool filtration pump basket and empty any debris if it is full up, also a backwash of the filter will reduce any back pressure and improve the suction on the vacuum.
        1. Always backwash the filter after vacuuming the pool and check the pump and skimmer baskets for debris.
        1. After vacuuming the swimming pool return the valves to their normal operating positions and remove the vac equipment from the pool and store safely away from the pool and out of sunlight.
