Owners of single-family homes that are not connected to the water supply network must decide how to supply their homes with water. Quite often, they choose a well. Although many people still associate wells with burdensome operation, the days of buckets and cranks have thankfully become a thing of the past. All that is needed is a properly selected submersible pump to enjoy water at the right pressure at all water outlets. Read on to find out which submersible pump is best for a single-family home.
A submersible pump is used to extract clean water from great depths. It is used for wells deeper than 8 meters, as well as for water reservoirs. Its most important feature is its ability to generate high pressure, ensuring an adequate flow at all water outlets. It usually has a compact design—a long cylindrical shape containing a motor and hydraulic system. However, to perform its functions properly, it must be selected individually. There is no single answer to the question of which pump is best for a single-family home, as several factors must be taken into account. First and foremost, it is necessary to determine the pumping head, soil and water conditions, water demand, and the type of well, including the diameter and depth of the borehole and its distance from the building.
- Pumping head is one of the most important parameters, as it determines the pressure the pump must generate, taking into account approximately 20% of linear and local losses. It is therefore the difference between the highest liquid outlet and the water table. To select the right pump power, measure the distance from the water table to the water connection in the building, and then from the connection to the highest outlet point. Add both values together, then add 20% of the geometric pumping head and an additional 20 meters to maintain the correct pressure at the tap. This will ensure that the pump is selected to meet the specific demand.
- The soil and water conditions on the property are also important. It is certainly worth knowing the depth of the aquifer, whether there are significant level fluctuations, and, above all, what the water quality is. This will be particularly important if the water contains a large amount of sand, as it will then be necessary to select a pump with suitable parameters and a reinforced construction.
- For the pump to operate efficiently, it must also be matched to the type of well. It is extremely important that the pump diameter be smaller than the diameter of the casing pipe, which is part of a deep well. This will not only allow the device to be installed freely, but will also force water to flow around the pump and provide better motor cooling.
- The final factor that should influence the choice of pump is determining the water demand. To do this, consider the number and type of water outlets, as well as the required pressure. Only then will it be possible to select a pump with the required capacity.
A submersible pump will operate fully effectively only if it is selected individually. To choose the best pump for a single-family home, it is worth consulting sellers and manufacturers, who will analyze all the factors and help you make the best choice.
