Why Choose the Trevoli CMB 5-57E?
The Trevoli CMB 5-57E is part of Trevoli’s stainless steel multistage pump range, designed to provide mains-style water pressure for homes supplied by rainwater tanks or stored water systems.
This model is a step up from the smaller SP3 and SP5 models and is well suited to larger homes, lifestyle blocks and water systems with higher household demand.
Compared with a basic jet pump, the multistage design helps deliver smoother pressure, quieter running and efficient operation for everyday household water use.
Best Suited to Flooded Suction Installations
The CMB 5-57E is best suited to flooded suction installations. This generally means the water source sits above or level with the pump, allowing water to naturally feed into the pump inlet.
For applications where the pump needs to draw water up from below the pump position, one of the Trevoli SP self-priming models may be more suitable.
If you are unsure whether your tank position suits this model, contact us before ordering and we can help confirm the best pump option for your setup.
Supplied with DSK Automatic Controller
This package includes the DSK Automatic Controller, allowing the pump to start automatically when water is required and stop when demand ends.
That means when you open a tap, turn on a shower, or use an appliance, the pump automatically activates to provide water pressure. When water demand stops, the controller shuts the pump off.
The controller helps create a simple, practical water pressure system without needing to manually switch the pump on and off.
A Strong Foundation for a Complete Water System
The CMB 5-57E can be paired with rainwater tanks, sediment filters, carbon filtration, UV treatment and pressure tanks to create a more complete water solution for rural and off-grid properties.
For drinking water use, we generally recommend pairing tank water systems with suitable filtration and UV treatment depending on your water source, household use and local requirements.

Frequently Asked Questions
Does this pump come with a controller?
Yes. This product is supplied with a DSK Automatic Controller, which allows the pump to start and stop automatically when water is being used.
Is this suitable for a rainwater tank system?
Yes. The Trevoli CMB 5-57E is well suited to household water supply from rainwater tanks and clean stored water systems, particularly where the pump is installed in a flooded suction setup.
What does flooded suction mean?
Flooded suction generally means the water source sits above or level with the pump, allowing water to naturally feed into the pump inlet. If the pump needs to draw water up from below its position, a self-priming SP model may be more suitable.
Can this pump supply a large home?
Yes. This model is designed for domestic water supply and is well suited to larger homes, lifestyle blocks and higher-demand household systems. Final suitability depends on the number of outlets, pipework, tank position and pressure requirements.
How does this compare with the CMB SP5-47E?
The CMB 5-57E is the larger step-up option and is better suited to larger homes, lifestyle blocks and higher-demand systems. The CMB SP5-47E is a strong medium to large household option and is self-priming, while the CMB 5-57E is best suited to flooded suction installations.
Do I still need a pressure tank?
Not always. The DSK Controller provides automatic pump control, but a pressure tank may still be recommended in some systems to reduce pump cycling, improve system feel and extend pump life.
Can this be used with filters and UV treatment?
Yes. This pump can be used as part of a complete water system with sediment filtration, carbon filtration and UV sterilisation. For drinking water applications, appropriate filtration and water treatment should be selected based on your water source and household needs.
Is this pump suitable for dirty water?
No. This pump is designed for clean water applications. It should not be used for dirty water, sewage, greywater or water containing debris.
Need Advice?
Choosing the right water pump depends on your tank location, pipe length, number of outlets, household size, filtration requirements and whether the system will be used for drinking water, irrigation or general household supply.
