Several factors to consider when properly sizing a submersible pump system will stand the test of time.
- Well-depth,
- Estimated yield of water supply,
- Static (standing water level)
- Drawdown (pumping water level) and
- Offset distance (from well to pressure tank)
The above items need to be equated to ensure that your submersible pump system will effectively and efficiently meet water usage needs. According to the State of California regulations, licensed professionals must install and service pumping systems. Therefore, the efficiency of a water system is entirely dependent on proper pump selection and system installation.
Submersible pumps are one of the most reliable and efficient means of water delivery on the market today. Unfortunately, when it comes to submersible pumps, you usually get what you pay for if you are not careful. The main parts of a complete submersible pump system are the pump, piping, pit-less adapter, pressure tank, and controls. The pump consists of a 230-volt electric motor mounted to the pump end. This pump is attached to piping, usually 15/20 foot joints of threaded PVC, and set to a specific depth. The pressure tank is a unique tank with an air “bladder” inside the steel tank. This air bladder allows the pump system to “build pressure” as the pump pushes water into the tank and compresses the trapped air. The pump turns off by a pressure switch that detects when proper cut-off pressure is reached. When a spigot opens, the compressed air pushes the water out of the tank. And will continue to do so until the cut-on pressure is met and the pump turn back on.
