8. Pumps
Pumps and pump controllers must be accessible and fitted with barrel unions for service and
maintenance.
It is recommended that all surface mounted pumps be protected from the elements with a suitable
pump cover.
Submersible pump accessories such as pump stands, high inlets, floating suction hose kits assist in
the pumping cleaner water that is found at higher levels in the rainwater tank.
See pump installation accessories on page 13.
9. Water Tanks
Water borne algae and roof litter can accumulate at the bottom of your rainwater tank that can be
sucked up by your pump. To reduce filter blockages we recommend that suction outlets on rainwater
tanks be 100 mm from the bottom of the tank (see page 10), and submersible pumps elevated by 90
mm (see pages 10,11).
