Davey Evolution in-tank pump system AKA EVO MKII

Some years back now, Davey Water Products teamed up with Tankworks Australia (now Kingspan Water) to develop the EVO Mark Two pump system for rainwater tanks.  The EVO MKII is a compact solution that includes filtration chambers and a submersible pump connected via standpipe to the Rainbank water switch.  This system replaced the EVO MKI – also an in-tank system – from Whites International, comprising of a Rainsaver hydraulic town/tank water switching device, coupled with a DAB Divertron submersible pump.

Professionally installed rainwater systems are low maintenance; but not NO maintenance.

Common maintenance issues or problems you may find with the EVO rainwater pumping systems include

  • blocked filter
  • pulsing water (water hammer) when switched to town water supply
  • town water supply lock out
  • electrical dead short which will cause your Safety Switch to trip your power board.

Having worked for Tankworks for a number of years, and maintaining a close working relationship ever since, Jim Steel of Water Tactics has extensive experience with the EVO systems.  Water Tactics offers EVO water system servicing,  trouble-shooting, spare parts, replacement filters and specialised testing equipment.

We can provide a full assessment of your EVO MK I or MK II system and offer maintenance, repair and replacement services.  Ask Jim about a range of of alternative solutions for your rainwater capture, storage and water pumping requirements.
