What does sand in the water mean in practice?
In a well, the problem may result from a damaged well filter, too high pump capacity, or an unstable aquifer.
When does it matter?
Sand abrades fittings, blocks valves and quickly overloads fine filter cartridges.
Which solutions are related to it?
First the well and pump are assessed, then a separator, settling tank or pre-filter selected for grain size and flow is used.
