FAQs
Can I use this stopcock for hot water?
No, this product is specifically designed for cold water services only.
Is this suitable for underground installation?
Yes, the durable polypropylene body is rated for both above and below-ground use.
What is the maximum pressure this can handle?
The stopcock is pressure tested up to 16 bar.
Does this stopcock require special tools?
It uses a compression fitting, meaning it can largely be installed by hand, though a wrench may be used for final tightening.
What pipe size does this fit?
It is designed specifically for 20mm plastic or MDPE pipes.
Can it operate in freezing temperatures?
It is rated for temperatures down to -10°C, though you should always insulate pipes to prevent water freezing inside the system.
Troubleshooting
Leakage at the compression nut
Ensure the pipe is fully inserted and the nut is tightened evenly. Check that the internal 'O' ring is clean and free of debris.
Difficulty turning the handle
Check for sediment accumulation or mineral deposits in the valve mechanism. Flush the system to clear debris.
Pros and Cons
Pros
- Resistant to rust and chemical corrosion
- Pressure tested up to 16 bar for safety
- Suitable for underground installations
- Simple, quick compression installation
- High operating temperature range for cold water services
Cons
- Not compatible with hot water systems
- Requires specific pipe sizing (20mm)
- Plastic threads may be prone to cross-threading if forced
Setup, Compatibility & Care
- Preparation: Ensure the pipe ends are cut square and are free from burrs or sharp edges that could damage the internal seals.
- Insertion: Slide the pipe through the nut and compression ring until it seats firmly against the internal stop.
- Tightening: Hand-tighten the nut securely. Use a wrench to add a final quarter-turn if necessary, but avoid overtightening to prevent cracking the plastic body.
- Care: While the unit is durable, avoid using petroleum-based lubricants on the seals, as they may degrade the rubber. Periodically check the valve operation to prevent mineral buildup if installed in areas with hard water.
