EWS Heater Guard 1.5″ – Sediment & Scale Protection for Water Heaters

The EWS Heater Guard 1.5″ is a rugged inline protection unit designed for homes with larger plumbing (1½″ lines). It combines a 5-micron pre-sediment filter and food-grade polyphosphate media to trap sediment and inhibit mineral scale from damaging your water heater, plumbing, and fixtures.

Features & Benefits

• Dual Action Protection — 5 µm pre-sediment filter removes rust, sand, silt, and suspended solids before they reach your heater.
• Scale Control — polyphosphate media helps reduce scale buildup on heating elements and internal surfaces, extending life expectancy.
• Reversible Flow — installs in either direction, offering flexibility in plumbing set-ups during retrofits or system upgrades.
• Fully Assembled — arrives preloaded and ready to mount, reducing installation effort and downtime.
• High Flow Capacity — supports larger household demand due to the 1½″ design.
• Built to Last — constructed with food-grade materials and designed to meet compliance standards.

Technical Specifications

*Performance varies depending on water quality and usage conditions.

Installation & Use Notes

• Recommended for installation on the cold-water inlet of your water heater—the unit should be upstream of the heater.
• For well water, additional pre-treatment may be needed—test water quality before installing.
• Do **not** use with softened water supplies containing sodium or potassium chlorides; such salt may impact media effectiveness.
• Install in cold-water line only, and observe direction if marked; reversible for compatibility.
• Replace the filter annually (or sooner in heavy sediment conditions) to maintain performance.
