Sand, grit and cloudiness
Why is there sand in my well water?
Fine sand and turbidity from unconsolidated aquifers destroys softener resin, blocks UV and wears out pump seals.
How you notice it
- Grit in aerators, toilet tanks and the bottom of glasses
- Cloudy water that clears when left standing
- Cartridge filters plugging monthly
Why it happens
Sand-and-gravel and alluvial aquifers, or a screen and pump combination pulling more than the formation can deliver cleanly.
The fix
- Flushable spin-down prefilter as the first stage
- Backwashing turbidity filter where cartridges plug monthly
- Have the driller check screen condition and pump setting depth
