FAQ
Common pump problems and solutions with the Wallace MPEP-3000 automatic surface-mounted pump
Why won’t my Wallace pump start?
If the pump doesn’t start, it’s usually due to a lack of water supply, trapped air in the suction line, or a tripped circuit breaker. These prevent the press-control system from activating.
Check that your tank or mains supply is delivering water, reset the breaker, and make sure suction lines are sealed with no air leaks. Once the water supply is restored and the line bled, the Wallace automatic water pump’s built-in run-dry protection allows the pump to restart normally.
Why is my Wallace pump noisy or vibrating?
Excess noise or vibration often comes from air in the suction line, loose pipe fittings, cavitation (air bubbles collapsing), or poor mounting. If not fixed, this can wear parts prematurely.
Bleed the suction line to remove air, tighten fittings, ensure the pump is secured on a firm base, and check for a steady water supply. Proper installation and air-free operation will keep this compact surface-mounted booster pump running quietly.
Why is my pump losing pressure or flow?
Reduced pressure or flow usually indicates a blocked inlet, dirty filters, or restrictions in the pipework. Sometimes the water source itself cannot keep up with demand.
Clean or replace filters regularly, check pipework for obstructions, and confirm the tank or mains source provides enough water. With clear lines and good supply, the Wallace MPEP-3000 water booster pump delivers smooth pressure across multiple outlets.
Why is my pump overheating or tripping the power?
Overheating or power trips can occur if the motor is overloaded, the airflow around the pump is poor, or the power supply is unstable.
This light commercial water booster includes thermal overload protection to prevent damage. Make sure the pump is installed with good ventilation, confirm power supply stability, and ensure plumbing isn’t creating excessive strain on the motor.
Why is my pump leaking?
Leaks usually come from worn seals, damaged gaskets, or long periods of dry running. If left unattended, leaks reduce performance and may cause water damage.
Inspect seals and gaskets as part of routine maintenance, and replace if needed. The automatic run-dry shutoff helps prevent internal wear, but leaks should be repaired promptly to avoid more serious problems.
Why does my pump switch on and off too often?
Minor plumbing leaks often cause rapid cycling, incorrect pressure control settings, or a mismatch between pump capacity and water demand.
Check your plumbing for leaks, confirm the pressure control is correctly set, and ensure the low-pressure system booster pump is sized to suit your household. Adding a small pressure tank can also reduce unnecessary cycling.
What if my pump won’t prime?
Priming failures happen when the suction line contains air, joints aren’t airtight, or the water level is too low. Without priming, the pump cannot draw water.
Fill the suction line with water, tighten joints, and make sure the supply source is adequate. Keep suction lift within the recommended maximum of 5 m for reliable operation.
Can air bubbles damage the impeller?
Yes. Prolonged cavitation, when vapor bubbles form and collapse inside the pump, can damage impellers and reduce efficiency.
Ensure a steady water supply, minimise suction lift, and avoid restrictions at the inlet. The constant-pressure water booster’s stainless steel impellers are robust, but preventing cavitation is essential for long service life.
Is the MPEP-3000 powerful enough for a family home?
Customers sometimes worry the 3000 model won’t deliver enough pressure for larger households. With multiple bathrooms or heavy appliance use, smaller pumps can struggle to keep up.
This residential and light commercial pump is ideal for smaller to medium homes or baches with moderate water demand. For bigger houses or families running several showers at once, Aqua Works may recommend stepping up to the MPEP-5000 or 6000 to ensure constant pressure everywhere.
Can the MPEP-3000 run on low-pressure tank water?
The easy-maintenance pressure pump works well with both mains and tank water. It’s fitted with run-dry protection, so if your tank gets too low, the pump will shut down safely and restart when water returns.
