In WA watering via your reticulation is restricted to 2 days per week on mains water and 3 days per week if you have a bore system from spring to winter. During winter you are not allowed to use your reticulation system except for testing and repairs. Tlc Services Perth advise bore owners to turn on there bore at least once per month to help prevent the pump from seizing up and to keep its prime otherwise when September comes and you turn it back on it will not work.
