Installation & Compatibility Notes
Before installation, ensure the gauge port is clean and free of old thread sealant or debris. Wrap compatible thread sealant or Teflon tape onto the ¼″ thread, and tighten by hand, then use wrench for a snug but not over-tight installation. Mount the gauge so that the dial is clearly visible from the service area. For filters with unusual port locations or accessory gauge ports, confirm port size matches ¼″ NPT or use appropriate adapter.
Maintenance Tips
- Periodically check the gauge face for fogging or moisture ingress—if present, replace the gauge.
- Ensure the dial needle remains at zero before system startup; a needle stuck off zero may indicate internal damage or pressure creep.
- During filter backwash or service, note normal pressure reading so you can recognise when the filter is restricted.
- Replace the gauge if it consistently reads significantly different than expected operating range for your filter system.
