Why Choose the Trevoli CMB SP3-47E?
The Trevoli CMB SP3-47E 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 practical choice for smaller homes, cabins, baches, tiny homes and modest household water systems where reliable pressure and quiet operation are important.
Compared with a basic jet pump, the multistage design helps deliver smoother pressure, quieter running and efficient operation for everyday water use.
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 SP3-47E 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 SP3-47E is well suited to household water supply from rainwater tanks and clean stored water systems.
Can this pump supply a house?
Yes. This model is designed for domestic water supply and is best suited to small to medium homes, cabins, baches and modest 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 SP3-47E is the smaller option and is better suited to small to medium homes, cabins and lighter household use. The CMB SP5-47E is the next step up and is better suited to larger homes, higher demand systems or properties with more outlets.
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.
Is this suitable for off-grid homes?
Yes. The pump is suitable for off-grid homes using rainwater tanks or stored water systems, provided the power system can support the pump’s electrical load.
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.
