Domestic water pressure booster pumps are installed to enter a building’s water supply. They raise the water pressure to sufficient levels. Like domestic mains, in order to provide adequate flow and pressure for consumers. By raising the water pressure, it’s possible to take advantage of the inherent power of gravity and deliver water further up the building without a need for a larger diameter pipe. This can be great news if you live in an apartment block or other tall structure, as it can save on drilling work and associated costs.

If you have a private well in your house, you might wonder if you should install a pressure booster pump to increase water pressure and flow. Water supply lines in older houses often have issues with low water pressure. This is caused by friction loss as the water flows through the tubing and electrical wires that supply water to different parts of your house. Booster pumps can help solve this problem.
What is a domestic water pressure booster pump?
A domestic water pressure booster pump is a device that increases the water pressure flowing from the main supply into your home, which can be helpful if you have low water pressure on one or more taps.
They can also be used to deliver a constant flow of hot water to multiple outlets simultaneously without loss of pressure or flow rate – this is particularly important if you have a shower and bath and want to use both simultaneously.
If you’ve ever craned your neck to get wet hair under the shower stream or had to angle a saucepan to fill it with enough water carefully, you’ll know what we mean.
If your house has low mains water pressure, this can cause problems throughout and affect the performance of appliances like showers and washing machines. A domestic water pressure booster pump will help boost the mains’ water supply and increase flow rates and pressures.
How do domestic water pressure booster pumps work?
Domestic water pressure booster pumps are typically used in private homes with low water pressure. If your home has low water pressure, you may be unable to draw enough hot and cold water from your taps or appliances. This can lead to poor performance when you use your dishwasher and washing machine and inferior showers. Domestic water pressure booster pumps work by taking in your home’s raw mains supply and boosting its flow rate before sending it out again to the rest of the house.
Domestic water pressure booster pumps are designed to increase the pressure of water coming from your taps, showers, and toilets.
The pump is connected between the incoming mains water supply and the tap/shower/toilet. It consists of a centrifugal pump driven by a single-phase motor. Such a pump is normally installed in a fixed position but can be changed using a portable base for mobile requirements.
When turned on, the pump will run until it detects the preset pressure has been reached (the setting is made using a small screw on the back of the unit). Once this pressure is reached, the pump will automatically switch off. As taps or showers are opened and closed throughout your home, it may be necessary for the pump to turn on and off to help maintain your desired water pressure.
When to use a water pressure booster pump?
If you notice that there is not enough water pressure in your home, you might consider installing a domestic water booster pump. There are many reasons that the water pressure in your home could be below.
One reason could be that many other people are using the same water supply as you are. Another reason could be a leak in one of the pipes. Lastly, if you have just moved into a new house, it could be due to the age of the pipes or a lack of maintenance by previous owners. In this case, you can use a domestic water booster pump to improve your problem.
The minimum required pressure for homes is 100kPa and businesses require at least 200kPa. Your local council will be able to tell you what pressure your area receives. If yours isn’t high enough, you should consider installing a pump.
A standard pump can increase the water pressure in your system by as much as 40psi (pounds per square inch). However, this depends on how big your installation is and how efficient it is.
Different types of domestic water pressure booster pumps
A few different types of domestic water pressure booster pumps are available in the market. Each one of them offers different benefits and is suitable for different applications.
Centrifugal Booster Pump:
The Centrifugal Booster Pump is usually used for small to medium-sized houses with 3-4 bathroom/toilet facilities or any other application where there is a need for boosting water pressure. This pump is designed with a multi-stage centrifugal impeller, which can deliver up to 140 liters per minute of pressurized water.
Vertical Multistage Booster Pump:
The Vertical Multistage Booster Pump is used in small to large-scale commercial applications, including high-rise buildings and apartments, pumping stations, industrial plants, etc. This pump has a high-efficiency motor that provides great performance and low energy consumption.
Horizontal Multistage Booster Pump:
This water booster pump consists of multiple impellers connected in series to each other inside a pump casing. A motor powers the impellers through a shaft rotating at high speeds. The Horizontal Multistage Booster Pump delivers more pressure than a single-stage pump while consuming less power, but it has a lower flow rate.
Apart from being installed in a newly built home, these pumps can also be used to replace old ones or simply improve on them to enhance the performance of your plumbing system at home. The pumps come into play when there is a need to increase the pressure of water flowing through pipes in a house.
Even though there may be other methods of doing this, using a pump offers more benefits than using any other method. The most important point that you should note about domestic water pressure booster pumps is that they help increase the pressure of water flowing through the pipes and not necessarily increase the amount of water flowing through them.
Systems for domestic water pressure booster pumps
Constant Pressure (CP) Booster Systems
The constant pressure booster system is probably the most used domestic water pressure booster system. In this system, the pressure in the tank will remain constant. As long as there is sufficient flow to maintain that level of pressure. When flow decreases and the water demand is higher than the supply, this causes a pressure drop. At this point, the controller will turn on the pump to replenish the tank until it reaches the required pressure setting. Then it will shut off again – this process will continue until demand drops.
Demand (D) Booster Systems
Demand (D) booster systems are designed for residential and commercial applications of up to 30 psi. They are made up of a booster pump, either a jet pump or centrifugal pump, and a pressure switch. The booster pump does not require a pressure tank as it runs only when the home or building requires demand. The system is connected to the municipal water supply line. When the switch senses that water pressure falls below the setpoint, it starts the booster pump. When the desired pressure is reached, typically 30 psi to 40 psi, it stops the booster pump until demand drops again.
Variable Speed (VSD) Booster Systems
Variable speed systems are becoming a more common choice for commercial and industrial applications. This is due to their ability to deliver water at a constant pressure. Which, in turn, lowers energy consumption.
A variable speed booster pump system consists of a variable frequency drive (VFD), motor, pressure transducer, and controller. The controller monitors the pressure in the system and adjusts the speed of the pump motor to maintain constant pressure.
This type of system can offer significant advantages over conventional fixed speed pumping systems as it offers benefits including:
Energy Savings
The greatest benefit of installing a VSD booster system is reducing energy costs by up to 60%. These systems have reduced start-up currents than standard constant pressure pumps. Which means they are less likely to cause damage to your power supply. They also reduce wear and tear on the pump motor, increasing its lifespan.
Constant Pressure
As the name suggests, these systems deliver water at a constant pressure regardless of demand. This is achieved by constantly monitoring and adjusting the pump motor’s speed. This is based on demand and flow rate. As well as ensuring no drop in pressure. A VSD booster system will automatically increase or decrease pump motor speed as needed. To maintain consistent water pressure throughout your
What is the best size of water pressure pump to choose?
If you have low water pressure at your house and want to increase the pressure, you’ll need to install a water pressure booster pump.
To determine what size water pressure pump is required for your home, firstly measure the incoming water pressure. If you don’t already have a water meter, ask your local plumber to install one.
Next, decide on how much more water pressure you want. This will most likely depend on what the water pressure is currently at. As well as what you plan on using it for.
For example, your current shower has poor flow and the water temperature fluctuates when someone turns their tap on or flushes the toilet. In this case a medium-sized pump will probably be sufficient. Suppose several people in the house require constant hot showers and/or multiple bathrooms connected to the tank system. Here, a larger pump may be required.
How to replace your booster pump?
Installation of a domestic water pressure booster pump is very simple and can be done by anyone. You only need a little bit of plumbing knowledge.
- The first step is to shut down the mainline to avoid water flow during the installation.
- Once the mainline is shut down, you will have to place the booster pump in front of the main pipe, where it would be able to take in water from it.
- Water booster pumps are normally placed vertically with their head facing up and their tail facing down.
- Another important thing to note is that the pump should be placed above the ground level to easily drain out all water from inside its chamber once it is turned off.
- After placing the pump, you need to connect two pipes to its inlet and outlet.
- The inlet pipe should be connected with the main water line, and the outlet pipe should be connected with another pipe that leads to your home.
- Connecting pipes to both ends of the pump is not very difficult but still, make sure that a quality glue or sealant like PVC cement is used on each joint so that no leakage occurs.
Once all this is done, turn on your mainline and check if there are any leaks or not.
