The Harvey G1240 Riser Pipe Kit is a pair of essential internal tubes that connect the softener's head assembly to the resin tanks. Specifically designed for 3/4-inch inlet/outlet H2O-series models, these riser pipes ensure that water is directed correctly through the resin bed for effective softening.
As a genuine Harvey spare part, the G1240 is manufactured to withstand constant mains pressure and the corrosive environment of a water softener cabinet.
⚠️ Compatibility Check
-
Inlet/Outlet Size: Fits all models with standard 3/4-inch (22mm) ports.
-
H2O-Prefix Models: Including:
-
Harvey Crown
-
Mini Max
-
Twin-Tec S3 & S4
-
-
Note: If your model has 1-inch ports and a separate salt bin, you require the G1954 kit instead.
Key Symptom: The "Invisible" Pin-Hole Leak
The most common reason for replacing the G1240 Riser Pipes is the development of microscopic pin-hole leaks.
-
The Problem: Over time, localized friction or material fatigue can create tiny holes in the riser pipe wall.
-
The Result: Water "short-circuits" the softening process. Instead of traveling through the full depth of the resin, hard water leaks directly into the outlet pipe.
-
The Sign: You may notice your water isn't as soft as it used to be, or you see "weeping" inside the cabinet near the tank connections, even though the external plumbing is dry.
-
The Solution: Replacing the pipes as a pair ensures both tanks maintain equal pressure and 100% softening efficiency.
Features & Benefits
-
Genuine OEM Fit: Ensures a perfect, watertight seal with the H2O manifold and internal distributors.
-
Restores Softening Quality: Eliminates internal bypass leaks, ensuring every drop of water passes through the ion-exchange resin.
-
Matched Pair: Supplied as a set of two to refresh both cylinders simultaneously, preventing future imbalance issues.
-
Durable Food-Grade Material: Safe for all domestic drinking water applications.
