Harvey H2O Meter Gearing | Genuine Replacement Gears for Water Softener Calibration

Ensure your Harvey water softener regenerates with precision by choosing the correct Meter Gearing. These genuine Harvey gears (G0921, G0920, G2251, G0919, G0892) are used to set the "gallons-to-regeneration" ratio. By matching the gear to your local water hardness, you prevent salt wastage and ensure a constant supply of soft water.

⚠️ Selection Guide: Match Your Water Hardness

Choosing the right gear depends on the PPM (Parts Per Million) or Degrees Clark of your water supply. Use the table below to identify the correct part number for your area:

Key Symptoms: Why Change Your Meter Gearing?

• Moving House: If you take your softener to a new area with different water hardness, you must swap the gear to recalibrate the system.

• Salt Usage is Too High: If your gear is set for "Standard" hardness but you live in a "Low" hardness area, the machine will regenerate too often, wasting salt.

• Hard Water Breakthrough: If the gear is too large (e.g., 1000) for a very hard water area (e.g., 500 range), the resin will exhaust before the gear triggers a regeneration.

• Physical Wear: Over many years, the plastic teeth on the gear can wear down, leading to a "slipping" meter that fails to trigger cycles.

Features & Benefits

• Non-Electric Precision: These gears are the heart of Harvey’s kinetic (water-driven) technology—no batteries or timers required.

• Direct OEM Fit: Genuine Harvey parts ensure perfect mesh with the internal drive cogs of H2O-prefix models.

• Optimized Efficiency: Accurate gearing can save up to 15% in salt costs per year by preventing unnecessary regenerations.
