Types of Water Pumps We Service & Install
Pressure Booster Pumps
Pressure booster pumps increase water pressure throughout your home or building. They are commonly installed in landed properties, upper-floor HDB units, and old condominiums where PUB mains pressure alone is insufficient. AOT installs and services single and multi-pump booster sets, including those with variable frequency drives (VFD) for energy efficiency.
Submersible Pumps
Submersible pumps are used in water tanks, underground sumps, and drainage applications. They are submerged directly in the liquid they are pumping. AOT services, repairs, and replaces submersible pumps in HDB, condo, and industrial settings. Common issues include motor burnout, impeller wear, and float switch failure.
Jet Pumps
Jet pumps are used to draw water from shallow wells or ground-level water tanks. They are common in kampong-style landed properties and older industrial sites. AOT inspects and services jet pump installations, checking foot valves, priming, and suction lines.
Sewage & Drainage Pumps
For basement carparks, low-lying properties, and commercial kitchens, sewage pumps handle waste water drainage. AOT installs and maintains sewage pumping systems, including alarm systems for high-water level detection.
Common Water Pump Problems
- π Pump runs but no water output
- π§ Pump runs continuously without shutting off
- π Low water pressure despite pump running
- π Noisy or vibrating pump
- β‘ Pump trips the circuit breaker
- π Water surge and pressure fluctuations
- π΄ Pump will not start at all
Many of these faults can be diagnosed and repaired on-site. AOT technicians carry common spare parts including pressure switches, capacitors, float switches, and impellers.
Our Water Pump Service Process
- Inspection & Diagnosis: We assess the pump condition, check pressure, flow rate, and electrical supply.
- Cleaning & Overhaul: We clean the pump body, impeller, and pressure vessel. We check seals and bearings for wear.
- Component Replacement: Worn parts β pressure switches, capacitors, impellers, mechanical seals β are replaced with genuine or OEM-equivalent parts.
- Testing & Commissioning: We run the pump under load, check pressure settings, and test automatic cut-off.
- Documentation: We provide a service report and recommend any future maintenance actions.
Pressure Pump Sizing for Singapore Homes
Choosing the right pump capacity is important. An undersized pump will not deliver adequate pressure; an oversized pump wastes energy and can damage pipes and fixtures. AOT considers:
- Number of bathrooms and simultaneous users
- Building height (head pressure required)
- Incoming mains pressure from PUB
- Flow rate requirements (litres per minute)
- Pipe diameter and layout
We recommend energy-efficient variable speed pumps (Grundfos, Wilo) for most residential installations β they adjust automatically to demand and can reduce electricity consumption by up to 50% compared to fixed-speed models.

FAQs β Water Pump Singapore
How do I know if I need a water pressure booster pump?
If your shower pressure is weak, water takes long to fill bathtubs or tanks, or you notice low pressure only when multiple taps are running simultaneously, a booster pump may be the solution. AOT can measure your current water pressure and advise accordingly.
How often should a water pump be serviced?
For residential booster pumps, annual servicing is recommended. For commercial and industrial applications with higher usage, servicing every 6 months is advisable. Regular servicing extends pump life and prevents unexpected failures.
Can AOT replace my existing pump with a more energy-efficient model?
Yes. We can replace older fixed-speed pumps with modern variable-speed inverter pumps (Grundfos SCALA, Wilo SiBoost) that are quieter, more efficient, and maintain more consistent pressure.
Is PUB permission required to install a water pump in Singapore?
For residential properties drawing from PUB mains, a booster pump must not create negative pressure on the mains supply. AOT ensures pump installations include proper non-return valves and are compliant with PUB requirements.
