Clack WS1 Bypass Valves

Description

The Clack WS1 Bypass Valve is a factory-designed bypass assembly used with Clack WS1 and WS1.25 control valves found on many water softeners and filtration systems. The bypass allows you to isolate the water treatment equipment from the plumbing system for servicing, maintenance, or temporary bypass operation.

This assembly is most commonly identified by part number V3006 and is widely used across residential and light commercial water treatment systems.

Key Features

• System Isolation – Allows the water treatment unit to be serviced without shutting off water to the entire building.
• Quick Bypass Operation – Two red handles control water flow, letting you switch between service mode and bypass mode instantly.
• Tool-Free Service Design – Oversized hand-tightened nuts connect the bypass to the valve body, making installation and removal simple.
• Durable Composite Construction – Made from reinforced composite materials with EPDM seals and O-rings for long service life and corrosion resistance.
• Four Operating Positions – Service, bypass, diagnostic, and shut-off positions allow technicians to work on pressurized systems while maintaining water supply.

Compatibility

The Clack WS1 Bypass Valve (V3006) works with many Clack control valve models, including:

• WS1
• WS1TC
• WS1CI
• WS1EE
• WS1EI
• WS1CS
• WS1SP
• WS1SQ

These valves are commonly used on water softeners, carbon filters, iron filters, and whole-home filtration systems.

Specifications

Part Number – V3006Valve

Type – Dual-handle bypass valve

Connection Size – 1″ standard (fittings vary)

Material – Reinforced composite / polypropylene

Seals – EPDM O-rings

Applications

Clack WS1 bypass valves are commonly used in:

• Residential water softeners
• Whole-house carbon filtration systems
• Iron and sulphur filtration systems
• Commercial water treatment systems

The bypass allows untreated water to flow around the system temporarily while repairs or maintenance are performed.

Maintenance

To maintain proper operation:

• Inspect bypass O-rings (e.g., V3105) during service.
• Lubricate seals with food-grade silicone grease.
• Replace worn O-rings to prevent leaks.
• Ensure both handles are aligned correctly for the desired position.
