Clack WS1 Bypass Valve

Clack V3006 Bypass Valve Suits Clack 1190FP Upflow Valve – Ideal for NZ pH & Bore Water Systems Overview The Clack V3006 Bypass Valve is a genuine OEM valve designed for Clack WS1/WS1.25 control valves, including the popular Clack 1190FP upflow head used across New Zealand in pH correction and bore water treatment systems. In addition to standard bypass functionality, it is commonly used in NZ installations as a manual blending valve, allowing you to mix untreated bore or rainwater with calcite-treated water to achieve the right balance of pH and hardness. Why This Matters in NZ Many NZ water supplies—especially bore water and rainwater—tend to be: Acidic (low pH) Low in alkalinity Aggressive on plumbing Calcite filters (with 1190FP upflow valves) correct pH, but can: Over-correct pH Add excess hardness Cause scaling in hot water systems 👉 The V3006 solves this by letting you blend treated and untreated water to suit your household. Key Features ✅ Designed for Clack 1190FP upflow systems ✅ Manual blending capability – ideal for pH correction setups ✅ Full bypass function for servicing and maintenance ✅ Simple, reliable operation (no power required) ✅ Genuine Clack part (V3006) ✅ Built tough for NZ residential and rural installs Blending Function (pH Systems) The V3006 can be used to dial in your water quality: What you can control: Final pH level Total hardness Scaling potential Typical NZ use: Reduce “chalky” or scaling water after calcite filters Fine-tune water from acidic bore supplies Balance treated water for household plumbing protection How It Works The dual-handle design allows three operating modes: Service Mode – 100% through the filter Bypass Mode – untreated water only Blend Mode – mix of treated + untreated water 👉 For blending, both handles are left partially open and adjusted to suit your water test results. Compatibility Clack WS1 control valves Clack WS1.25 control valves Clack 1190FP upflow head (common NZ pairing) Calcite pH neutralisers Bore water filtration systems Whole-house treatment systems Specifications Part Number: V3006 Connection Size: 1” BSP-compatible setups via tail kits Material: Heavy-duty engineered polymer Mounting: Direct fit to Clack valve body Common NZ Applications ✅ Bore water treatment (acidic water correction) ✅ Rainwater pH balancing systems ✅ Calcite upflow filters ✅ Rural and lifestyle block water supplies ✅ Service bypass for filtration/softener systems Why Choose This Setup (V3006 + 1190FP)? This combination is widely used across NZ because it offers: ✔ Simple manual control (no electronics) ✔ Lower cost than automatic blending valves ✔ Flexibility for changing water conditions (seasonal bore variation) ✔ Easy to maintain and adjust Installation Tip (NZ Conditions) Start with full service mode (100% treated water) Gradually open bypass side to introduce raw water Test: pH (aim ~7.0–7.5 for most homes) hardness Mark valve positions once dialled in What’s Included 1 × Clack V3006 Bypass Valve Pre-installed O-rings Optional Add-On (Recommended) Pair with: Clack 1190FP upflow valve Calcite media Basic test kit (pH + hardness)
