All in One Slimline
- the pump and mains water switch are hidden!
- valuable real estate and wall space are not wasted
- it has clean straight lines
- the submersible Italian stainless pump is whisper quiet
- the hydraulic water switch does not require power
- copper pipe tails make for the easiest possible connection
- it is pressure tested on delivery to your slab

The latest innovation in steel tanks is the new steel "All in One" slimline tank which integrates a submersible pump and mains water controller inside the water tank. That means no more unsightly rainwater controller switches and pumps on the side of the home. The submersible pump and rainwater control switch are incorporated in the body of the tank but both are easily accessible to be able to maintain or check at any time.
Slimline Water Tanks for New Home Builders
Because the Waterplex "All in One" steel slimline tank is factory assembled and tested before delivery, it is ideal for new home installations because:
- every water tank is fully tested before delivery
- every pump and rainwater control switch are pressure tested before delivery
- the tank and rainwater harvesting package are delivered as a complete unit to the slab on site
- there are only two copper tail connection points for the plumber to connect to - and no more to do!
- The powerful submersible pump is so quiet you will struggle to even hear it
- there are no unsightly boxes, control units or external pumps as with many other tank installations. It looks great!
- there is no power requirement for the mains water control unit. Because it works on differential pressure (mains water vs. tank water), there is no requirement for a power connection
- it saves money in the long run and the risk of loss or theft of the pump and controller is reduced
