How would that stop sediment ?
Sediment in a well can actually be caused by the pump cycling on and off. With a pressure tank only for control the pump puts out maximum flow until the tank is full, and then the pump shuts off and the flow is zero. A 10 GPM pump will draw 10 GPM until the tank is full. This causes the water in the well to wash through the well screen, perforations, or even just fractures in the rock fast enough to bring the sediment with it. At the same time, the water level in the well is dropping, causing previously wet sediment on the walls of the well to dry out and sluff into the well. When the pressure tank is full the pump abruptly shuts off and the water level quickly rises, washing over the sediment like waves at the beach. When a pump is constantly cycling on and off, the well is being surged up and down, which is a method used by drillers when they want sediment to sluff off during a cleaning operation.
Adding a Cycle Stop Valve to a system like this can greatly reduce sediment. Even though many people have a 10 GPM or larger pump, rarely is more than 3-5 GPM being used in the house. With a Cycle Stop Valve the pump is only pumping as much water as you are using and the well is only producing as much as you are using. So, when using a 3 GPM shower for example, the CSV makes the pump draw only 3 GPM from the well. The CSV will draw a steady 3 GPM from the well and pump for as long as you are in the shower or have a 3 GPM sprinkler running. This will cause the water level in the well to drop only slightly if any, and stay at that level, eliminating the well wall drying out and sluffing off as well as wave action as the well does not need to recover. The small 3 GPM flow is not enough to bring the sediment through the well screen, perforations, or fissures in the rock. What sediment does get into the well never makes it up to the pump, as the velocity of the water in the casing isn't high enough to lift the sediment. Most times the flow is so low the velocity in the drop pipe connected to the pump is not even high enough to bring sediment up with it.
In other words, when using a CSV, the flow rate is usually so low and the velocity so slow the water comes up without any sediment. When water is moving up a pipe slowly enough, the sediment just settles back to the bottom and never makes it to the cartridge or spin down filter.
I get slammed from some people for claiming the Cycle Stop Valve solves every problem with a pump system. However, nearly every problem with a pump system is caused by cycling. It should then make sense that something designed to stop cycling would also solve nearly every problem with a pump system.
Like I said, pump the well out good, eliminate the pump cycling, and you may not even need a filter.
