Having issues with your Wallace MPEP-6000 automatic surface-mounted pump? Aqua Works provides expert servicing and repairs to keep your water flowing.
Wallace automatic horizontal multistage booster pump
- Designed for tank or mains supply: suitable for both above-ground (preferred) and below-ground water tanks.
- Surface-mounted system: easy installation in a pump shed or beside your tank.
- Versatile performance: works equally well on mains pressure or low-pressure rural water systems.
- Simple plumbing setup: 32 mm inlet and 25 mm outlet connections.
- Fully automatic operation: no manual intervention required.
High-capacity water booster pump with powerful variable speed performance
Smart variable speed drive (VSD): Unlike a standard single-speed pump that runs flat out and then cuts off, the Wallace MPEP-6000 pressure pump continuously adjusts its motor speed to match the exact water demand in your home or business.
Constant pressure, no matter the demand: Whether it’s one tap or five showers running at once, the pump automatically speeds up or slows down to keep pressure steady — no more frustrating bursts or drops.
Energy saving operation: Because the pump isn’t always running at full speed, it uses less power overall, reducing running costs while extending pump life.
Protects your system: The soft start and stop prevent sudden pressure shocks (water hammer), reducing wear on your plumbing, fittings, and appliances.
Perfect for high-demand use: Ideal for large homes, motels, apartments, or irrigation systems that need reliable flow at varying times of day.
Low maintenance required with this residential and commercial booster pump
- Very low maintenance design backed by Wallace engineering.
- Smooth, quiet operation with fewer moving parts to service.
- Built-in safeguards protect the pump and extend its lifespan.

FAQ
Common pump problems and solutions with the Wallace MPEP-6000 automatic surface-mounted pump
Why won’t my Wallace pump start?
If the pump won’t start, it’s often due to a lack of water supply, a tripped breaker, or air trapped in the suction line. These issues interrupt the pump’s regular operation.
The Wallace booster for large homes is fitted with run-dry protection and auto-recovery, meaning it will shut down safely if water is unavailable and restart automatically once supply returns. If the issue persists, check the water source, reset the breaker, and ensure suction lines are airtight.
Why is my Wallace pump noisy or vibrating?
Excessive noise or vibration is usually caused by air in the system, cavitation (air bubbles collapsing inside the pump), loose fittings, or poor mounting. Left unaddressed, this can reduce efficiency or damage components.
This rainwater tank booster pump runs quietly when installed correctly. Bleed any air from the suction line, secure the pump on a firm base, and ensure the water supply is steady. Correct installation eliminates most vibration and noise.
Why is my pump losing pressure or flow?
A blocked inlet, clogged filters, or restrictions in the pipework typically cause a sudden drop in pressure or flow. In some cases, the water supply may be too low to meet demand.
Make sure to clean filters regularly, inspect pipework for blockages, and confirm an adequate water supply. With clear lines, the Wallace high-capacity booster pump’s variable speed drive ensures constant pressure, even with multiple outlets running.
Why is my pump overheating or tripping the power?
Overheating or electrical trips can happen if the motor is overloaded, ventilation is poor, or there are voltage fluctuations.
The fully automatic Wallace water booster includes thermal overload protection to prevent permanent damage. Make sure the pump is installed with adequate airflow, confirm the power supply is stable, and reduce system restrictions that may cause strain.
Why is my pump leaking?
Leaks generally come from worn seals, damaged gaskets, or running the pump dry for too long. Continuous leaks can lead to reduced pressure and water wastage.
Inspect seals and gaskets regularly and replace them if worn. This surface-mounted booster pump helps avoid dry running with its automatic shut-off, reducing the risk of internal seal damage.
Why does my pump cycle on and off too often?
Frequent cycling is often caused by small leaks in the plumbing system, incorrect pressure settings, or a mismatch between pump and demand.
Check your system for leaks, ensure the control settings are correct, and match usage patterns to pump capacity. The Wallace constant-pressure water booster’s VSD technology reduces unnecessary cycling by adjusting speed to match demand.
What if my pump won’t prime?
Priming issues occur when air enters the suction line, the pump isn’t airtight, or the water level is too low. Without proper priming, the pump can’t move water.
Refill the suction line, tighten joints to prevent air ingress, and confirm there is enough water in the source. A correctly set up suction system will allow the Wallace pump for above-ground and underground water tanks to operate smoothly.
Can air bubbles damage the impeller?
Yes. Prolonged cavitation — when vapor bubbles form and collapse inside the pump — can pit and wear the impeller, reducing efficiency and lifespan.
Maintain adequate water supply, keep suction lift as low as possible, and avoid restrictions in the inlet. The automatic domestic water pump’s variable speed control helps reduce cavitation risk by matching pump speed to available water.
