FAQs
What is the main purpose of this draincock valve?
This valve is primarily designed for draining residues from radiators or sections of a heating system, making maintenance, replacement, or cleaning easier by allowing water to be drawn off without draining the entire system.
Can this valve be used on any type of pipe?
It is designed for use with standard 15mm pipes, typically copper or compatible plastic pipes, using compression fittings for connection.
Is this valve suitable for high-pressure systems?
While robust, it is designed for standard domestic heating and water system pressures. Always check system specifications to ensure compatibility.
How often should I operate the valve if it's not in regular use?
It is recommended to operate the valve (turn it on and off) at least quarterly to prevent the internal gate mechanism from seizing due to disuse.
What material is the valve made from?
The valve body is constructed from brass, and it features a rubber seal and 'O' rings for watertightness.
Can I use this valve for fine flow control?
No, this is a gate valve designed for fully open or fully closed operation and is best suited for infrequent use like draining. It is not intended for modulating or fine-tuning water flow.
Troubleshooting
Leak from compression fitting
Ensure the olive is correctly positioned and the compression nut is tightened sufficiently. If the leak persists, the olive may need to be replaced, or the pipe may be damaged.
Valve is stiff or difficult to turn
Operate the valve several times to loosen any potential debris or sediment. Ensure the handle is not obstructed. If still stiff, professional inspection may be needed.
Valve does not shut off completely
Check for debris lodged around the valve seat. Ensure the valve is fully closed. If the problem persists, the valve may be worn and require replacement.
Pros and Cons
Pros
- Robust brass construction for durability.
- Easy installation with 15mm compression fittings.
- Effective for draining heating systems and radiators.
- Suitable for both hot and cold water applications.
- Provides a secure shut-off when properly closed.
Cons
- Gate valve design is not ideal for frequent on/off operation.
- Requires manual operation; no automation features.
- Primarily for draining and infrequent control, not fine-tuning flow.
- Compression fittings require careful tightening to prevent leaks.
Setup, Compatibility & Care
Setup:
- Ensure the pipe ends are clean, smooth, and free from debris.
- Slide the compression nut and then the olive onto the 15mm pipe.
- Insert the valve's plain shank into the pipe, ensuring it is fully seated.
- Slide the olive up to the valve body and tighten the compression nut firmly by hand.
- Use a wrench to tighten the compression nut an additional 1/2 to 1 full turn to create a secure seal. Avoid over-tightening.
Compatibility:
- Compatible with standard 15mm copper or plastic pipework suitable for compression fittings.
- Suitable for use in both hot and cold water plumbing and heating systems.
Care:
- Periodically check the compression fittings for tightness, especially after initial installation or temperature fluctuations.
- The valve exterior can be cleaned with a damp cloth. Avoid abrasive cleaners.
- Ensure the valve is operated occasionally (e.g., quarterly) to prevent the gate from seizing, especially if used infrequently.
