Protege 2350W Automatic High-Pressure Water Jet Pump Guide: Fit, Features & Considerations for Australian Homes

Protege 2350W Automatic Water Pump Guide for Rainwater, Irrigation and On-Demand Supply

The Protege 2350W automatic high-pressure water pump is designed to provide an on-demand pressurised water supply from sources such as rainwater tanks and suitable grey-water systems.

It combines a multi-stage stainless-steel pump with an electronic controller that monitors pressure and flow. Opening a tap or irrigation outlet can start the pump automatically, while closing the outlet allows the controller to stop it again.

The published figures are substantial: 2350W input, 80m maximum head and 7200 litres per hour published flow. But those numbers should not be read as a promise that every tap will receive maximum pressure and maximum flow at the same time.

Real performance depends on suction height, vertical lift, pipe diameter, pipe length, bends, valves, filters, outlet demand and the overall plumbing design.

Testing statement: Firebusters has not personally tested this pump. Specifications are based on the current Edisons listing and Protege instruction manual checked in September 2026.

What Does an 80m Maximum Head Actually Mean?

Maximum head describes the maximum theoretical vertical water column the pump can overcome under particular conditions.

It is not the same thing as saying the pump will deliver 7200 litres per hour at a point 80 metres above the pump.

As resistance rises, available flow normally falls. A proper pump curve shows the relationship between flow and head, but the current Edisons listing and manual reviewed for this model do not provide a detailed performance curve.

This means the published 80m head and 7200L/h figures should not be treated as simultaneous operating performance.

For real system sizing, consider:

• vertical height from the water source to the highest outlet;
• suction height;
• pipe length;
• pipe diameter;
• filters;
• valves and fittings;
• number of outlets operating together; and
• required pressure at the final tap or sprinkler.

Maximum Suction Lift: Approximately 9m

The Protege manual states that the pump has a maximum suction lift of roughly 9 metres and should not be installed higher than this above the water source.

That figure is a maximum limit, not necessarily the best installation target.

The manual also says that where intake height exceeds around 4 metres, a larger-diameter suction pipe should be used.

Reducing suction height where practical can improve reliability because pumps generally work more effectively pushing water than trying to lift it through a long restrictive intake line.

Self-Priming Does Not Mean No Priming

This is one of the most important points in the Protege manual.

The pump is described as self-priming, but it still requires an initial prime.

Self-priming means that once the pump and suction system are correctly filled, the pump is designed to retain enough water to restart without needing to be manually primed every time.

Priming may still be required again if:

• the pump has been unused for a long period;
• air enters the suction pipe;
• a fitting leaks;
• the foot valve fails;
• the pump has been drained; or
• the water source falls below the suction intake.

Do not repeatedly run the pump dry in an attempt to make it draw water.

Suction Pipe Setup Matters

A powerful motor cannot compensate for a badly designed suction line.

The Protege manual states that the suction pipe should:

• not be smaller than the pump inlet;
• remain completely airtight;
• angle slightly upward towards the pump to reduce air locks;
• have the intake submerged by at least about 500mm; and
• use a foot valve at the end of the intake pipe.

Air entering the suction side can cause poor flow, loss of prime and irregular pump operation.

Use proper pressure- and suction-rated plumbing rather than lightweight hose that can collapse under suction.

Automatic Controller: What It Does

The electronic controller is one of the main reasons to choose this model over a basic transfer pump.

It monitors system pressure and flow so that water demand can trigger the pump automatically.

For example:

• a tap opens;
• system pressure falls;
• the controller starts the pump;
• the outlet is closed; and
• the controller stops the pump when its operating conditions are satisfied.

The manual also provides an adjustment for cut-in pressure. Turning the adjustment towards plus increases the cut-in pressure, while turning it towards minus decreases it.

Changing controller settings affects system behaviour, so adjustments should be conservative and remain within the pump and plumbing limits.

Dry-Run Protection Is a Backup, Not a Normal Operating Mode

Edisons advertises a no-water shutdown function and dry-run protection.

This can help protect the pump when the tank runs empty or water supply is interrupted.

It should not be used as an excuse to intentionally operate the pump without water.

Repeated loss of water can indicate:

• an undersized tank;
• poor suction plumbing;
• a leaking foot valve;
• air entering the intake;
• blocked filtration; or
• the intake being positioned too high.

Find and correct the cause rather than relying repeatedly on the protection system.

Rainwater and Grey-Water Use

The current Edisons listing markets this pump for rainwater tanks, grey water and irrigation.

However, the current manual reviewed by Firebusters does not publish a solids-handling size or describe the pump as a dirty-water or sludge pump.

That distinction is important.

Do not assume that “grey water” means the pump can safely handle:

• sand;
• stones;
• fibres;
• food waste;
• heavy sediment;
• sewage; or
• thick sludge.

If using anything other than reasonably clean water, confirm filtration and water-quality requirements for your exact system before installation.

This is not a sewage or macerator pump.

Can It Supply Household Taps?

The automatic-controller format can make this type of pump suitable for a pressurised domestic-style water system, subject to the actual installation.

But pump capacity is only one part of the issue.

If water is to be connected to household plumbing, particularly where rainwater or another alternative supply could interact with mains drinking water, Australian plumbing requirements, backflow protection and local water authority rules may apply.

Water quality also needs to be suitable for its intended use.

Firebusters therefore would not describe this pump alone as making rainwater or grey water suitable for drinking or unrestricted household use.

Installation Conditions From the Manual

The manual provides several conditions that are easy to overlook.

The pump should be:

• installed in a dry, well-ventilated location;
• used where ambient temperature does not exceed about 40°C;
• fixed to a solid, flat surface;
• installed horizontally;
• supported so pipework does not place stress on the pump body; and
• protected from inappropriate weather exposure.

The manual also recommends a non-return valve on the discharge side to help control water hammer and says this becomes compulsory where the delivery water column exceeds 20 metres.

Electrical Installation

The pump is a high-powered mains electrical appliance.

The current Edisons information describes it as pre-wired for 240V supply. The controller and pump still need to be installed where electrical connections remain protected from water and weather.

Before use:

• inspect the power lead and plug;
• do not use damaged electrical equipment;
• keep connections away from wet surfaces;
• ensure the supply is appropriate for the equipment;
• do not modify the controller wiring; and
• disconnect the pump from mains power before maintenance.

The manual states that a damaged supply cord should be replaced by the manufacturer or a similarly qualified technician.

Continuous Duty: Read the Claim Carefully

Edisons currently markets this model as having a 100% duty cycle and being designed for continuous operation.

That should still be understood within normal operating limits.

Continuous duty does not mean the pump can operate indefinitely with:

• no water;
• blocked flow;
• incorrect voltage;
• excessive ambient temperature;
• poor ventilation;
• an undersized suction pipe; or
• operation outside its hydraulic limits.

The supplied manual also contains generic domestic-use wording, so Firebusters would not infer heavy industrial or commercial suitability from the 2350W figure or the marketing description alone.

Why Pipe Size Can Matter More Than Motor Wattage

A 2350W pump connected to restrictive plumbing can still produce disappointing results.

Small pipes, long pipe runs and many elbows increase friction loss.

The result can be lower flow and lower pressure at the outlet despite the pump having a high published maximum head.

The manual specifically says the delivery-pipe diameter should be selected to suit the required flow and pressure at the outlet points.

For a large irrigation system or several simultaneous outlets, proper hydraulic sizing is worth doing before buying the pump.

Firebusters Practical Recommendation

This Protege pump makes the most sense where you need an automatic high-head pump for a rainwater tank, irrigation system or another suitable clean-water-style supply and you have enough demand to justify its capacity.

Its strongest documented features are the 2350W motor, automatic pressure controller, 80m maximum head, 7200L/h published flow, approximately 9m maximum suction lift and 25mm ports.

Do not buy it simply because 2350W or 80m sounds powerful.

Our recommendation: calculate the actual vertical lift, suction height, pipe size, pipe length and number of simultaneous outlets first. If the installation is complex, ask a plumber, pump supplier or irrigation specialist to confirm the required duty point.

Buyer Checklist

Frequently Asked Questions

What is the exact Protege model?

The safest identifier is SKU PMPPWCPROB4C0. Edisons currently lists model PWC-408, while its box-content wording also refers to PWC-40B.

What is the maximum head?

The published maximum head is 80 metres.

What is the published flow rate?

The manufacturer documentation lists 7200 litres per hour.

Can it deliver 7200L/h at 80m head?

Do not assume so. Maximum head and published flow figures describe different parts of pump performance. A pump curve is needed to determine flow at a particular head.

What is the maximum suction lift?

The manual states approximately 9 metres.

Does a self-priming pump need priming?

Yes. The manual specifically says an initial prime is required. It may also need re-priming if air enters the system or the pump has been unused for a long period.

What size are the connections?

The inlet and outlet are both listed as 1 inch or 25mm.

Does it have dry-run protection?

Edisons advertises no-water shutdown and dry-run protection.

Can it pump grey water?

Edisons markets the pump for grey water, but no solids-handling capacity is published in the manual. Do not treat it as a dirty-water, sludge or sewage pump.

Can it supply drinking water?

The pump specification alone does not establish that a water source is potable. Water quality and Australian plumbing requirements need to be addressed separately.

How much does it weigh?

The current Edisons page lists 11kg, while the manual specification table lists 10.15kg. This appears to be a documentation or batch difference.
