Rain Water Pumps for Brisbane, Gold Coast & Major Australian Metros
Rain water pumps move stored water from a rainwater tank to garden taps, hoses, irrigation, toilets, laundries, sheds, granny flats and selected household fixtures.
The correct rainwater pump depends on required flow, required pressure, tank location, suction conditions, pipework, number of outlets and how the water will be used.
Installed Today supplies rain water pumps across supported mainland Australian markets, with supplied and installed options available on selected pumps in eligible Brisbane and Gold Coast service areas.
What Matters When Choosing a Rain Water Pump?
What Is a Rain Water Pressure Pump?
A rainwater pressure pump takes stored water from a tank and creates enough flow and pressure to move that water through the plumbing to the required outlets.
Depending on the setup, those outlets might include a garden hose, sprinklers, toilets, a laundry, outdoor taps or multiple fixtures throughout an off-grid home.
A standard rainwater pump does not automatically provide mains-water backup. Where automatic switching between tank water and mains water is required, compare a dedicated rain-harvesting system instead.
What Will the Rainwater Pump Supply?
Garden & Hose
A lower-demand pump can suit one garden tap, hose or basic watering application where strong whole-home pressure is unnecessary.
Irrigation
Sprinklers and irrigation zones can require significantly more flow and pressure, particularly when several outlets operate together.
Household Tank Supply
Toilets, laundries, showers, kitchens and other household fixtures require a pump sized around realistic peak demand.
Sheds & Granny Flats
Rainwater pumps can supply detached buildings where the tank, plumbing and pump are designed for the required fixtures.
Off-Grid Homes
Whole-home tank supply requires enough flow and pressure for normal residential use across several fixtures.
Acreage Properties
Longer pipe runs, elevation and multiple water-use areas can significantly affect pump selection.
Rainwater Pump Flow Rate and Pressure Explained
Pump sizing requires both flow and pressure.
| Measure | What It Tells You | Why It Matters |
|---|---|---|
| Flow Rate | How much water the pump can move | Needs to cover the outlets operating together |
| Pressure | The force available within the water system | Affects taps, showers, sprinklers and household performance |
| Head | A measure used to express pump pressure capability | Helps account for elevation and system resistance |
| Pump Curve | Shows available flow at different head levels | Provides a better sizing guide than maximum flow alone |
Do Not Choose a Rainwater Pump by Maximum L/min Alone
The maximum advertised flow rate is generally not the flow a pump will provide at every operating pressure.
As head increases, available flow changes. Long pipe runs, elevation, valves, filters and restrictive pipework can all increase the amount of work the pump needs to perform.
Compare the pump curve against the actual installation rather than assuming the highest advertised litres-per-minute figure automatically means the strongest real-world performance.
Tank Position and Suction Are Critical
A surface-mounted rainwater pump needs a suitable water path from the tank to the pump inlet.
Suction performance can be affected by:
- Vertical lift from the tank
- Distance from tank to pump
- Suction pipe diameter
- Air leaks in fittings
- Excessive bends and restrictions
- Tank outlet arrangement
- Foot or non-return valves where required
- Water level within the tank
A larger pump does not fix a poorly designed suction line. Good hydraulic layout remains important regardless of pump size.
Self-Priming Rainwater Pumps
Many surface-mounted rainwater pressure pumps use self-priming designs that can help establish water flow where the pump is drawing from a suitable tank arrangement.
Self-priming does not mean the pump can overcome unlimited suction lift, leaks or poor pipework.
The installation still needs to remain within the pump manufacturer's suction and priming requirements.
Rainwater Pumps for Garden Hoses and Outdoor Taps
Basic garden watering is one of the simpler rainwater-pump applications.
A pump supplying one hose or outdoor tap may not need the capacity of a larger household pressure system, making a practical fixed-speed pressure pump a common starting point.
Check required hose pressure, tank distance, elevation, pipe size and whether additional outlets may operate at the same time.
Rainwater Pumps for Sprinklers and Irrigation
Irrigation should be sized around the flow and pressure required by the sprinklers or irrigation zones rather than simply the number of sprinklers installed.
Multiple sprinklers can use significant flow, while long irrigation runs create additional friction loss.
Check the irrigation design, operating zones, sprinkler pressure, elevation and pipework before choosing the pump.
Rainwater Pumps for Off-Grid Whole Home Supply
An off-grid home relying on tank water needs a pump capable of supporting normal residential demand.
Showers, basins, kitchens, toilets, laundries and appliances can create much higher peak demand than garden watering.
Whole-home selection should consider:
- Number of bathrooms
- Number of occupants
- Simultaneous fixtures
- Required household pressure
- Tank-to-house distance
- Property elevation
- Pipe sizing
- Water filtration
Traditional vs Variable-Speed Rainwater Pumps
Traditional Pressure Pump
Conventional pumps typically operate at fixed motor speed and use a pressure controller or similar arrangement to start and stop as water demand changes.
Variable-Speed Pump
Variable-speed systems can adjust pump speed in response to demand to help maintain more consistent water pressure.
Which Suits?
Simple garden or moderate-demand applications may not need variable speed, while larger homes may value smoother household pressure.
Davey, TotalFlo, Bianco and DAB Rainwater Pumps
The current Installed Today rainwater-pump collection includes systems from Davey / TotalFlo, Bianco and DAB.
The range covers economy rainwater pressure pumps, garden and irrigation systems, larger household pumps and premium variable-speed whole-home options.
Current examples range from compact Davey TotalFlo and Bianco pressure pumps through to DAB Jetcom and premium DAB E.Sybox systems.
Premium Rainwater Pressure with DAB E.Sybox
The current rainwater collection includes DAB E.Sybox options for customers wanting premium variable-speed water-pressure control.
Variable-speed systems can be particularly useful for residential applications where demand changes regularly between one and several outlets.
Premium controls do not remove the need for correct hydraulic sizing. Tank supply, suction, required flow, pipework and system resistance still need to suit the pump.
Automatic Control and Dry-Run Protection
Many modern rainwater pressure pumps use automatic controllers to start the pump when water is required and stop it when demand ends.
Selected products can also provide protective functions intended to reduce the risk of prolonged operation when an adequate water supply is unavailable.
Controller functionality varies by model. Check the actual pump specifications rather than assuming all automatic pumps provide the same control or protection features.
Rain Water Pump vs Rain Harvesting Pump System
Rain Water Pump
Primarily moves water from a tank and provides pressure to the connected outlets.
Rain Harvesting System
Typically combines rainwater pumping with automatic control for mains-water backup where the plumbing system is designed for it.
Which Do You Need?
If tank water alone supplies the connected outlets, a standard pressure pump may be enough. If automatic mains backup is needed, compare rain-harvesting systems.
Rainwater Pump Location, Noise and Weather Protection
Pump location affects suction performance, noise, servicing and equipment life.
Position the pump according to the product's installation requirements with suitable pipework, power and service access.
- Close to the tank where practical
- Firm mounting surface
- Appropriate weather protection
- Suitable electrical supply
- Service accessibility
- Good suction pipe layout
- Consideration of nearby bedrooms
- Drainage around the pump area
Replacing an Existing Rain Water Pump
If the existing pump provided good pressure and flow before it failed, its performance is a useful starting point for the replacement.
If it always struggled, replacing it with an identical performance class may reproduce the same problem.
Before ordering, compare:
- Existing pump model
- Maximum and operating flow
- Pressure or head performance
- Tank location
- Suction conditions
- Pipe size
- Number of outlets
- Controller type
- Electrical supply
- Reason for replacement

Rain Water Pump FAQs
Common questions about choosing, ordering and installing rain water pumps for tank water, off-grid homes, irrigation and whole home water pressure.
What is a rain water pump best suited for?
A rain water pump is best suited to moving water from a rainwater tank to the home, garden, irrigation system or selected outlets. The right pump depends on whether you need whole home pressure, off-grid water supply, garden watering, irrigation or simple water transfer.
Which rain water pump should I choose?
Choose an economy pressure pump for basic tank water supply, a larger variable speed pump for whole home off-grid pressure, or an irrigation pump for garden watering and outdoor zones. The best choice depends on household size, number of outlets, pipework, tank position, flow demand and pressure requirements.
What is an off-grid rain water pump?
An off-grid rain water pump is used when a home relies on rainwater tanks for everyday water supply instead of standard mains water. It needs to provide consistent pressure to showers, taps, toilets, laundries and other outlets depending on the home’s plumbing setup.
What size pump do I need for an off-grid home?
The correct off-grid pump size depends on the number of people in the home, number of bathrooms, pipe size, filters, tank position, vertical lift, distance from the tank and how many outlets may run at once. Smaller homes may suit a simpler pressure pump, while larger homes often need a stronger whole home system.
Can a rain water pump supply the whole house?
Yes, selected rain water pumps can supply a whole home when correctly sized and installed. Whole home supply needs the pump, pipework, filtration, pressure control, electrical supply and tank setup matched to the property’s water demand.
Can a rain water pump be used for irrigation?
Yes. Rain water pumps can be used for irrigation, garden watering, sprinklers and outdoor taps when the pump is matched to the watering zones, flow rate, pressure requirement, pipe size and available tank water. Larger irrigation systems may need careful pump sizing before ordering.
Is an irrigation pump different from a whole home pump?
Often, yes. Irrigation pumps are usually selected for outdoor flow and watering zones, while whole home pumps are selected for consistent pressure inside the house. Some pumps may suit both uses, but only if the flow, pressure and plumbing setup are suitable.
Can one rain water pump run the house and garden?
In some setups, one rain water pump can run both household outlets and garden watering. This depends on pump size, tank location, flow demand, filters, irrigation zones, household usage and whether both areas may be used at the same time.
What is the difference between a fixed speed and variable speed rain water pump?
A fixed speed pump runs at a set speed when operating, while a variable speed pump can adjust its operation as water demand changes. Variable speed systems can provide smoother pressure and can be a better option for whole home or higher-comfort off-grid setups.
Do rain water pumps need filters?
Many rain water pump setups need suitable filtration or pump protection. Filters can help protect fixtures, appliances and the pump from sediment, but the correct filter setup depends on tank condition, water quality, pump type and whether the water is being used for the home, garden or irrigation.
Can I buy a rain water pump supply only?
Yes. Choose supply only if you already have a licensed plumber, pump installer or electrician arranged. Supply-only pricing is for the pump only and does not include installation, valves, fittings, pipework changes, electrical work, pressure controls, tanks, trenching, old pump removal, disposal or compliance upgrades unless selected separately.
Can I order a rain water pump supplied and installed?
Yes. Supplied and installed options are available for selected rain water pumps in eligible Brisbane and Gold Coast service areas. Availability depends on your address, tank access, pump type, plumbing layout, electrical setup, pipework and site requirements.
Does rain water pump installation include electrical work?
