Water pumps transfer water between points or remove wastewater from fixtures. A submersible pump operates below the water level, so its installation needs to allow for suitable immersion and access for maintenance. Connections must match the plumbing supplies specified for the system.

Water pumps are a key component of any plumbing system in both residential and commercial settings. They help regulate water pressure in a system and are frequently used for showers and appliances to ensure a consistent flow of water pressure.

Types of water pumps

There are many types of water pumps available for DIYers and professionals alike but it's essential to understand their unique qualities and functions before choosing the right one for you.

Dynamic water pumps

Dynamic water pumps make use of kinetic energy to move water from one point to the next. Dynamic pumps are rarely used in residential properties in New Zealand and are more commonly used in the chemical and commercial industries.

Positive displacement pumps

Positive displacement pumps are some of the most common types you’ll come across. These pumps can be further subdivided into external gear, gerotor, lobe, internal gear, peristaltic and vane pumps. Because of their design, the rotation takes place at a much lower speed. This makes them a good option for homes, but less ideal for large buildings such as shopping centres or office complexes.

Centrifugal pumps

Centrifugal pumps are very versatile as they can work with a wide range of liquids of different viscosity. These pumps offer high flow rates, which makes them ideal for agricultural purposes. These pumps can also be used to send water from a well or borehole to a home. Centrifugal water pumps are compatible with pneumatic systems as well and with the right plumbing parts can be easily connected.

The advantages of high-quality water pumps

One of the most prominent benefits of investing in high-quality water pumps is that they can help increase pressure and transfer water from one area to another reliably for years on end. This is because they are designed and engineered for their specific purpose using only the best materials available. Quality should always be prioritised with any component of plumbing, especially when mechanical parts are involved. In doing so, you’ll ensure you have a system that you can depend on time and time again.

How to choose a water pump that's right for you

The size of the pump is one of the factors to consider as it should match the system you’re installing it into. You’ll also want to consider such things as the LPM/PSI ratings, the inlet/outlet size, and the distance you need your water pumped. For anyone unfamiliar with these terms or plumbing in general, it's best to consult with the manufacturer and your local plumber who will be fitting the product to ensure you’re selecting the right option for the job. A domestic water pump needs a power supply suited to the installation; this matters particularly for a 12v water pump or a solar water pump.

How long should a house water pump last?

A sturdy, high-quality water pump should be able to last anywhere between eight to 15 years in New Zealand. However, this depends on various factors including the frequency of use and how often it’s maintained. Some other factors that may determine a pump’s lifespan are its location placement and the elements affecting it.

Where is the water pump usually located?

A water pump is usually placed not too far from the area it’s most likely to be used. The pump is usually placed on a flat surface for it to function smoothly. If the surface under the pump isn’t flat you’ll have some difficulty running it efficiently.

What affects the performance of a water pump?

Mechanical functions can affect the performance of a water pump. However, these problems are rare with high-quality pumps that are well-maintained and installed correctly before use. For you to keep your pump healthy it’s vital to service it regularly and choose one from a reliable brand.

What size water pump do I need for my house?

The ideal size of a house pump based on a 3 to 4-bedroom home in New Zealand should be anything with a flow rate of approximately 35 LPM on average. This should provide adequate water supply and pressure for this home. You can increase or decrease the size based on your needs.
