The Harvey H25 Replacement Twin Tank Kit is the definitive solution for major internal failures in high-capacity Harvey or Culligan 1-inch softeners. This kit includes a matching pair of brand-new cylinders, fully factory-loaded with premium ion-exchange resin, ready for installation.
Designed specifically for the robust H25 1-inch series, these tanks are the primary repair path for systems where internal filtration has failed, causing media loss.
⚠️ Mandatory Identification Check
To ensure this fits your system, confirm the following:
-
Ports: Your system must have 1-inch (28mm) Inlet/Outlet ports.
-
Cabinet: This model features a separate salt bin (the softener tanks are not housed inside the brine tank).
-
Brand Compatibility: Fits Harvey H25 and equivalent Culligan Twin Tank models.
-
Not Suitable For: Standard H2O, Crown, or Mini Max block-salt models (3/4" ports).
Key Diagnostic: When to Replace Your Tanks
Replacing the full tank assembly is the only viable repair when Resin Escape occurs. This is typically caused by:
-
Perforated Internal Filters: If one of the internal molded filters or distributors fails, the resin beads are no longer contained.
-
Resin in the Pipework: If you find small orange/gold beads in your kitchen taps, showerheads, or toilet cisterns, your internal tank filters have been compromised.
-
Sudden Hard Water: If the resin has escaped the cylinder, the system can no longer perform ion exchange, resulting in immediate hard water breakthrough.
-
Clogged Appliances: Resin escape can damage boilers and appliances. Replacing the tanks promptly is essential to protect your home’s plumbing.
Features & Benefits
-
Factory Loaded: Pre-filled with high-grade resin to ensure the exact volume and density required for 1" high-flow performance.
-
Complete Pair: Cylinders must be replaced as a pair to ensure balanced flow and consistent regeneration across both tanks.
-
OEM Quality: Genuine replacement cylinders designed to handle the higher pressure and flow rates of the H25 and H30 series.
-
System Restoration: This repair returns your softener to "as-new" internal condition, extending the life of your H25 unit by years.
Ordering & Availability
Lead Time: As a specialist H25 component, these tanks are built to order. Please allow a 7–10 working day lead time. We recommend checking current stock availability with our team before placing an urgent order.
