Why You Need a Sediment Filter (And How to Choose the Right One)
Well water is raw. It carries sand, silt, rust, and clay straight from the aquifer. Without filtration:
- Pipes clog → $1,500–$5,000 repair bills
- Fixtures stain orange
- Water pressure drops 20–50%
- Bacteria grow in low-flow zones
A sediment filter = protection + savings.
