Bianco Divertron 900 Submersible Rainwater Pump Kit
The pump sits inside the tank and a valve switches to mains when it runs low.
The owner's insights on the Bianco Divertron 900 Submersible Rainwater Pump Kit
These kits suit a rainwater tank that is deep enough to hold the pump inside it. A submersible pump sits under the water, so nothing stands beside the tank to take up room or be seen. DAB describe the Divertron as quiet in operation.
Pick the pump first. The Divertron 900 has its controller built in and works to a depth of 12 metres. The Autosub 100 carries a float switch, moves up to 100 L/min and runs on 750 W.
Then pick the valve. The AcquaSaver is solid brass with no electronics. The Rainsaver MK6 is a technopolymer unit that limits pressure to 200 kPa. Either one switches your house to mains water when the tank runs low, or the power goes.
These are kits for a licensed plumber to connect. They suit clean water, so your tank still needs an inlet strainer and a first flush device.
Why you'll love the Bianco Divertron 900 Submersible Rainwater Pump Kit
Sits under the water
Both pumps work inside your tank, so nothing needs to stand beside it.
Mains cover on every kit
Each kit has a valve that switches you to mains water when your tank is low or the power fails.
Built-in controller
The Divertron 900 starts and stops itself, so you need no separate pump controller.
Dry-run protection
Each pump is listed with dry-run protection, which guards it if your tank runs empty.
A float on the Autosub
The Autosub 100 has a low-level float on the pump to keep aerated water out of your supply.
Two valve options
On the Divertron 900 you can choose the brass AcquaSaver or the Rainsaver MK6.
Why you should consider a Bianco or DAB rainwater pump kit
DAB Pumps make the Divertron. White International of Milperra, NSW distribute it in Australia beside the Bianco and Rainsaver range. White International's listing says more than one million of the first Divertron generation were installed. Order through My Acre and we will beat any genuine like-for-like price you find elsewhere. If a warranty question ever comes up, you deal with us, not the maker.
Talk it through before you order
Tell us the depth of your tank and the taps you want on rainwater. We will match the kit.
Call todayWork out which kit you need
Step one: compare the three kits
| Kit | Pump | Valve | Power cable |
|---|---|---|---|
| Autosub 100 with Rainsaver MK6 | Bianco NXT Autosub, up to 100 L/min | Rainsaver MK6 | 10 m |
| Divertron 900 with AcquaSaver | DAB Divertron 900, built-in controller | AcquaSaver, solid brass | 15 m with plug |
| Divertron 900 with Rainsaver MK6 | DAB Divertron 900, built-in controller | Rainsaver MK6 | 15 m with plug |
Figures are from the White International listings and the pump data sheets.
Step two: check the kit against your tank and house
- 1. Measure the water depth in your tank against the pump rating: 12 m immersion for the Divertron, 7 m diving depth for the Autosub.
- 2. Measure the cable run from the pump to your power point. The Divertron cable is 15 m and the Autosub cable is 10 m.
- 3. Count the toilets, laundry and garden taps you want on tank water. Our rule of thumb: size for the taps that run at once, not for every tap in the house.
- 4. Choose the valve. The AcquaSaver is brass with no electronics. The Rainsaver MK6 limits pressure to 200 kPa.

What to measure before you decide

Frequently asked questions
What is in the Bianco Divertron 900 rainwater pump kit?
Each kit pairs a submersible pump with an automatic rain to mains changeover valve. The options are the Autosub 100 with a Rainsaver MK6, the Divertron 900 with an AcquaSaver, or the Divertron 900 with a Rainsaver MK6.
Does the Divertron 900 need a separate pump controller?
No. DAB build the electronics into the Divertron 900, so it starts and stops itself, with automatic restart and dry-run protection. The listing recommends a small 2 to 8 litre pressure tank.
How deep can the pump sit in the tank?
DAB list a maximum immersion depth of 12 metres for the Divertron 900. The Autosub 100 data sheet lists a 7 metre diving depth. Check your water depth against the pump you choose.
Should I choose the AcquaSaver or the Rainsaver MK6?
Both switch to mains water when the tank runs low. The AcquaSaver is solid brass with no electronics and is listed to 50 L/min. The Rainsaver MK6 limits pressure to 200 kPa.
Do these kits need a licensed plumber?
Yes. The Rainsaver MK6 manual says plumbing connections should be carried out by a licensed plumber. An underground tank or your water authority may also need extra backflow protection.
Can the pump handle dirty tank water?
No. DAB specify clean liquid, free from solid or abrasive substances, for the Divertron. Keep an inlet strainer and a first flush device on your tank.
Does the Autosub 100 include a float?
Yes. The data sheet lists a low-level control float on the pump, which keeps aerated water out of your household supply when the tank level drops.
How long is the pump power cable?
The Divertron 900 has a 15 m cable with a plug. The Autosub 100 has a 10 m cable. Measure from the pump position to your power point before you choose.
