The first step in determining whether your system is designed for optimal performance is to have a Flow Test done. Just like it sounds, this test will determine the rate of water flow, in gallons per minute, from your well. The results of this test are used to determine what pump size you need and how far down the pump needs to be set.
Next, a Water Analysis is made by a licensed lab. In each state acceptable limits are set for the naturally occurring minerals found in ground water. These results are carefully examined to determine what type of filters and water treatment are needed.
