Water Tank Pumps: Consider This Before Buying

To use tank water throughout your home, you'll need a water tank pump (also referred to as a pressure pump). The pump pumps water out of your tank, supplying high-pressure water to the numerous taps throughout your home.

In most cases, homeowners purchase water tank pumps to either have a supply of clean household water or for garden use. However, when selecting a water tank pump to buy, there are 3 things you need to consider:

1. Water Pressure

Your specific use for the tank water and required amount will determine the pressure required.

The pressure of water is measured in litres per minute (LPM). If you want to use your tank water for toilets and washing machines, lower water pressure will be sufficient, if you don't mind waiting a few minutes for the toilet tank or washing machine bowl to fill. However, if you require the water for showering or perhaps watering your garden, you will need a more powerful pump that can push out water at a higher pressure of approximately 20 LPM.

When looking for a water tank pump to buy, you need to take into account how many taps you have operating at the same time and what a suitable LMP would be for these taps.

For example, if you need a tap to run in the laundry, kitchen, and toilet all at the same time, you add the needed water pressure for each area to calculate the overall flow rate necessary. Compare this figure to the pump's "Max LPM" specification before buying.

2. Distance Between the Water Tank and Your House

Distance is an important consideration since a more powerful pump will be required to carry water from your tank to your home if your tank is located a considerable distance away from your home. For example, if you have a multi-story home and need to pump water to the upper floors.

When looking at pumps to buy, notice that some pumps are labelled as suited for tiny or multi-story residences, but in general, a pump with a head pressure of 20-50 LPM is required to transport water in a multistory building.

3. Electricity Usage

While it may be tempting to select the largest and strongest pump available, keep in mind that pumps use electricity every time a tap is turned on. The stronger the pump, the higher the electricity usage. Purchasing a pump that is too large for your requirements may result in higher power expenditures, cancelling out any hopes of saving on your bills.

Water Tank Pump Prices

The prices of quality water tank pumps vary according to the type of pump you require for your setup. Different types of water pumps include:

• Garden/External Use Pumps: Garden pumps are often the most affordable option since they are mostly only connected to one tap. They are intended to pump the water from a hose at a reasonable pressure, run a small sprinkler system, fill the pool, and wash the car. The Garden pump has a maximum flow rate of 40 to 60 LPM.

• House Pumps: House pumps typically have a substantially higher flow rate since they must feed water to several outlets and appliances at the same time while maintaining relatively consistent pressure. One method is to have many impellers in the pump. The impeller resembles a round fan meant to discharge water. The additional impellers work in phases, with one impeller delivering to the next and so on. This is referred to as a multistage pump. A typical multi-stage rainwater harvesting pump will have a maximum flow rate of roughly 100 LPM.

• Submersible Pumps: Submersible pumps are fitted and installed within a tank of water. They often have a separate controller mounted outside the tank. Submersible pumps are extremely quiet and take up no room outside of the water tank. These features have become the reason why these pumps are the preferred water pumps on the market and also tend to be more on the pricier side. Many submersible pumps are multistage pumps with maximum water flows ranging from 80 to 100 LPM.
