The Harvey G1545 Service Kit is an essential maintenance set for the H2O series. It is specifically designed to refresh the internal sealing and metering interface of the softener's head assembly. Whether you are performing a preventative annual service or repairing a specific metering fault, this genuine OEM kit ensures your system tracks water consumption with surgical precision.
⚠️ Compatibility Check
-
Models: Fully compatible with all H2O-prefix twin tank systems.
-
Brands: Fits Harvey Crown, Mini Max, TwinTec S3, and TwinTec S4.
-
Exclusion: Not suitable for the newer H20b or H20c models.
Key Symptoms: When to use the G1545 Kit
If your softener is failing to "count" the water used, it won't know when to regenerate. Watch for these specific signs:
-
Erratic Regeneration: The system regenerates too late (resulting in hard water) or too early (wasting salt).
-
Usage Tracking Failure: The internal meter disc isn't spinning or is sticking, often caused by perishing seals or internal friction that this kit resolves.
-
Inaccurate Metering: If you have confirmed the correct Meter Gearing is installed but the system still miscalculates capacity, the internal seals in the G1545 kit are likely compromised.
-
Water "Bypassing" Internally: Perished seals in the service kit can allow water to creep between chambers, confusing the pressure signals required for a clean regeneration trigger.
