You have checked the legal requirements, found a good water source and figured out what you want to use it for. Now you need to choose the right size pump for your system. The pump you select should match your household’s flow rate and pressure needs. Oversized pumps waste energy, while undersized pumps can result in low water pressure.
Septic tank installation is specified in GPM (gallons per minute). Most homes with three to four bedrooms require 8 to 12 GPM. When selecting a pump, you also need to consider the pressure requirement at your most demanding fixture. This requires calculating the friction loss in your pipe system. Friction loss depends on the length and diameter of your pipes, as well as the material and the pump design. The loss is compounded by elevation losses. For example, for every 10 feet of elevation, you lose 0.3 Bar of water pressure.

The next step is figuring out how much power your pump consumes in order to meet your daily consumption and a reasonable reserve. A rule of thumb is to calculate your daily pumping demand by dividing your household’s daily consumption by your area’s average daily solar generation. Add a buffer for cloudy weeks and emergencies.
Most household pumps run off of DC (12V or 24V). They need an inverter to convert the DC to AC. However, some newer power stations like EcoFlow DELTA 2 Max are designed with built-in DC to AC inverters to provide more efficient operation and reduce costs by eliminating the need for an additional inverter.
