Pump
The most appropriate pump depends on a lot of factors. We recommend constant pressure pumps for use with water tanks for the following reasons:
- they have run dry protection - so when you tank is empty your pump will not run - preventing pump damage;
- they support taps, timers and trigger nozzle hoses - ie you open a tap the pump will switch on - close the tap the pump will switch off;
Use our House Pump Selector to select a pump which suits your requirements and your price range.

Leaf Filtering and First Flush Diverter
Wet Earth recommends using a Leaf filter (Frogmouth Filter or Leaf Eater/Leaf Beater) to keep leaves and other debris out of your bladder tank. The Frogmouth Filter's design makes it useful as part of the tank overflow setup as well so we have included it as part of the one click shopping cart above.
We suggest that you consider installing a first flush diverter system. Whether this is required will depending on local regulations, your location and what you plan to use your water for.
