Low water pressure is a common problem faced by many homes in Malaysia, especially those who live in old, landed terrace houses. Having low water pressure is very stressful to deal with and makes it almost impossible to enjoy a quick shower after a long day at work.
With the increasing population in Malaysia, this is certainly not a new problem among households. One of the best solutions to overcoming low water pressure issues is by buying your own water pump at home. However, there are tons of water pump products on the market, and picking the right one is not as straightforward as you might think. To make it easier for you, we’ve shortlisted and reviewed some of the best water pumps available in Malaysia.
What is a Water Pressure Booster Pump?
A water pressure booster pump is a type of pump that boosts water pressure in residential homes. The typical water pressure increase you can expect from a pump is in the range of 15-psi and all the way up to 50-psi depending on the size of the pump.
Many booster pumps are also designed to turn on automatically when pressure is needed. However, some pumps have variable speeds that can be adjusted to maintain set water pressure. If you often experience low water pressure of less than 40 psi, then a water pressure booster pump is a good solution worth considering.
What Causes Low Water Pressure?
Booster pumps are commonly used to boost the city or municipal water supply for homes situated at a higher elevation from the municipal water supply, such as on a hill. Most Malaysia terrace houses water supply usually comes from a water storage tank placed on the roof truss.
This configuration almost certainly means that there will be insufficient and weak water pressure on the first floor. Without an electrical water pump, water pressure is only directly proportional to the difference in height between the water source and water discharge outlet.
Factors to Consider when Buying Water Pressure Booster Pump
Buying the best water pressure booster pump requires you to take into account several factors for your home. Here are a few things you can look for when picking the best booster pump.
Considering you’re getting a pump to boost your water pressure; the pressure boost is one of the most important things to consider. You need to check that the water pump is able to boost your water pressure enough for you to be happy. The average PSI (pounds per square inch) that a booster pump provides is in the range of 20 – 50 psi above your existing water pressure.
If your existing water pressure is in the very low range of 15-25 psi only, you may want to consider getting a booster pump that provides at least a 40 psi pressure boost.
Some booster pumps require dedicated circuits which also means installing advanced electrical work at the panel box. While there are many booster pumps that can be plugged into a 120-volt outlet, the length of the power cord may not be specified.
Home or Commercial Use
The type and specification of a pump model will depend on whether you’re using it for home use or commercial purpose. You will not require a high-pressure pump for home use. However, you may require a much more heavy-duty model for business use. Farmers and contractors rely on heavy-duty commercial water pumps for their work.
This simply means how long it takes for the water pump to pump a specific amount of water. Usually flow rate is measured by liters per minute or m3 per minute. It is recommended for you to go for a flow rate of more than 2500 liters per minute if you’re buying for commercial use. But if you only need a water pump for home use then a flow rate of 200 liters per minute is fine.
Although most pumps have an inlet size between 1 to 6 inches, some models have larger inlet sizes. Centrifugal water pumps sick in water from the inlet and discharges it through the outer valve. In such cases, it is recommended for you to go for a bigger size inlet so that your pump can pump out more water faster.
Some booster pumps have built-in pressure relief valves, check valves, and may even come with shutoff valves and other accessories. You should always verify what the booster pump comes with and what you may need to buy extra.
There are certain water pressure booster pumps that require you to purchase a separate pressure regulator for you to adjust the water pressure. Most homes may already have water pressure-reducing valves, but it’s recommended for you to always verify if you need to install one.
The best water pressure booster pumps are made from quality materials like stainless steel, which is highly resistant to rust and corrosion.

However, thorough maintenance and best performance require a professional technician to do the job. We strongly suggest engaging a qualified expert to conduct yearly maintenance on your water pump.
Machines such as water pumps require some inspection, maintenance, and servicing. Scheduling your routine check-ups will help you prevent any big issues and inconvenience later down the road.
Frequently Asked Questions
How do water pumps work?
The water pump runs on an electric motor that moves the impeller. This type of pump is known as a centrifugal pump. The impeller transports the water (technically called drive water) that is moved from the well and via a jet to the compartment at the front of the impeller.
The smaller electric pump units you see in many residential dwellings are a lightly different story. These types of water pumps feature a DC motor encased in a seal that connects to the impeller. You’ll find multiple coils surrounding a rotor right in the middle of the motor.
These coils feature magnets that form a permanent magnetic structure that transmits via the rotor. When you turn on the water pump motor, electricity will dun directly into the coils to instigate a magnetic field and cause the rotor to spin 180 degrees.
Once the rotor starts to spin, the electricity in the coils switches and it continues to activate the rotor until it comes to a full circle. As the rotor keeps moving and spinning, it will also activate the impeller to power up the pump and draw in water.
How long do water pumps last?
Submersible pumps should last anywhere from 8 to 10 years before you need to replace them. Some good pumps can even stay efficient for as long as 15 years without a break in function.
The average 2-wire residential pump can last 11 years on average with a range of 8-13 years in real-world conditions. If you’re looking at an average 3-wire well pump, then the average lifespan is about 12.5 years with a range of 10 to 15 years for real-life scenarios.
What types of water pumps are suitable for home use?
For domestic home usage, we recommend using a water pressure booster pump. Other common pump types such as centrifugal pumps and submersible pumps are commonly used for commercial use and not in residential houses.
Does a water pump use a lot of electricity?
The water pump still uses electricity when it’s actually running, but the usage is not nearly as bad. Most of the energy gets used during the initial start-up as more energy is required to kick-start the motor.
A pro tip for saving money despite this is to have a professional measure up your pump to your actual water needs. Many homes in Malaysia are actually using a pump that is 1 or 2 sizes larger than they need and thus wasting a lot of electricity.
What water pump size do I need?
When choosing a water pump for your house, you need to first consider the size of your home. Large homes with 4 bedrooms will need a pump rated eight to twelve gallons per minute (GPM). One way of being precise with your choice is to add one GPM for every water fixture.
Your fixtures can include appliances that use a substantial amount of water such as dishwashers, laundry machines, and showers. However, it is best to avoid choosing an oversized pump just to be able to cover everything as a larger pump will also lead to energy efficiencies in the house.
