I have a sediment tank before the filter that catches any sand particles with a specific gravity greater than water. It sure extends filter life.
While speaking of sand particles, did you realize one little particle of sand of the correct size can cause your water system to flood your house.
That one little sand particle stuck in the correct location of your laundry unit mixer valve can block the valve open causing the washing machine to over fill. All the yelling to stop, WOOHA, pushing the stop switch, un-plugging the unit from the electric outlet won't stop the flow. The manual water valves must be closed to stop the water.
The rule at our house "never leave with that appliance running" sure saved the basement from flooding. This was before the sediment tank and filter was installed and this near miss prompted that installation.
