When choosing a rainwater tank pump to use in cities like Perth and Melbourne in Australia, searching for the right rainwater tank can seem a little overwhelming at first. These days, many Australians use the internet as their first port of call when choosing a rainwater pump. While a quick google search on “rainwater tank pump” will provide you with a wealth of information, it can be difficult to decipher all the technical information and decide what is the best choice of rainwater tank pump for you.
There are many variables when choosing a rainwater tank pump in Australia. You need to have some basics in place - like checking your rainwater harvesting and storage system and tank capacity meets local regulations, especially in large cities like Melbourne and Perth. You also need to consider all the aspects around flow calculation including hose length, the quantity of water being pumped, the distance, where the pump is located relative to the water source, the water pressure, capacity of your water pump etc. The calculations can be quite technical so it is wise to get some professional advice from a rainwater tank supplier.
When you are designing your rainwater harvesting and storage system in Perth and throughout Australia, there are some basic choices around the type of rainwater tank pump you need.
Self priming rainwater pump
The demand for self priming pumps is high as priming a water pump of any kind can be quite challenging for the uninitiated. Fortunately, water pumps have evolved significantly. Self priming rainwater pumps are particularly useful if the pump is higher than the rainwater tank, if the rainwater tank is underground, the pipeline is not straight or when the rainwater tank is positioned quite a distance away from the end point of the irrigation.
On demand rainwater tank pumps
On demand rainwater water pumps are sometimes referred to as constant pressure pumps. Put simply they maintain the water pressure so that when you turn the tap on you instantly have water. The motor speed of the pump adjusts to maintain water pressure while you are using it.
Pressure pumps also fall into this category. These types of water pumps are typically used with a rainwater and storage system that comprehensively services the whole house, whole garden or both. Rainwater harvesting and storage systems are typically used in cities like Perth and Melbourne and are also very popular in rural areas of Australia.
Transfer rainwater pumps
Transfer pumps are not ideal for 24/7 use with rainwater tanks and are not typically used as part of a rainwater harvesting and storage system. They are great for transferring water from a rainwater tank to another storage tank or for emptying out rainwater tanks to clean them. They are especially useful in remote locations or for temporary irrigation projects.
External rainwater pumps
These are most typically used with rainwater tanks and are located near the base of your tank and close to a power source. They are relatively easy to install. They have the disadvantage of being unsightly and noisier than submersible pumps.
Submersible rainwater pumps
Submersible rainwater pumps will help keep your neighbours happy as they are much quieter to run. This is especially important in heavily populated cities in Australia such as Perth and Melbourne.
Solar powered rainwater pumps
Solar powered pumps are really just like any other type of rainwater tank pump, with the added feature of being able to connect to a solar array or solar panel and draw all their energy from it. More advanced solar pumps have the option to alternate between power sources.
In more general terms, rainwater tank pumps are sometimes referred to as garden pumps or whole of house pumps. Another general term is an irrigation rainwater pump.
While it may seem confusing to navigate all the options available, the best thing to do is speak to a professional rainwater tank supplier and installer. They will have the local knowledge, technical knowledge and product knowledge to steer you in the right direction. If you choose to have them both supply and install your rainwater harvesting and storage Perth you can often negotiate a very good deal.
