EWS Heater Guard 3/4″ – Sediment & Scale Protection for Water Heaters
Water Heater Protection — EWS Heater Guard 3/4″
Extend the life of your water heater and avoid costly repairs with the EWS Heater Guard 3/4″. This compact inline system uses a 5 micron pre-sediment filter plus food-grade polyphosphate to reduce sediment and inhibit mineral scale buildup on heating elements and internal surfaces. It’s fully assembled for quick install and built to EWS’s high quality standards.
Features & Benefits
- Dual protection: 5 µm pre-sediment removes dirt, rust, sand, and suspended particles.
- Scale inhibition: FDA-approved, food-grade polyphosphate helps reduce scale formation on heating elements and in plumbing.
- Reversible flow: Install in either direction for easier plumbing flexibility.
- Fully assembled: Ships ready to mount—no manual assembly required.
- Broad compatibility: Suitable for both traditional tank and tankless water heaters.
- Made in the USA & compliant: Meets or exceeds all relevant standards.
Technical Specifications
| Model # | EWS-HEATER-GUARD-3/4 |
| Micron Rating | 5 µm pre-sediment |
| Media | FDA food-grade polyphosphate (scale inhibitor) |
| Flow Rate | Up to ~9.5 gallons per minute |

Installation & Use Notes
- Install on the cold water inlet to your water heater for maximum protection.
- Not designed to treat microbiologically unsafe water—ensure disinfection where needed.
- Do not use with salt water or softened water (e.g. sodium or potassium chloride systems), as that can reduce performance.
- For well water, testing is required to confirm whether the Heater Guard is sufficient, or if additional treatment is necessary.
- Replace the internal filter element (BB-Guard-Filter-3/4) annually or earlier if heavy sediment is present.
