Product Information
Full details
The Primaflow QQE Isolating Valve is an essential component for plumbers and homeowners looking to manage water flow efficiently within 15mm domestic or commercial plumbing systems. Its primary benefit is the push-fit connection mechanism, which significantly reduces installation time and eliminates the need for specialized soldering tools, though it requires precise pipe preparation to ensure a watertight seal.

Extended Product Information
FAQs
Is this valve suitable for central heating systems?
Yes, provided the system uses standard 15mm piping and the temperature remains within the rated tolerances of the valve.
Do I need to use PTFE tape with this valve?
No, the push-fit connection uses internal O-rings to create a seal, so PTFE tape is not required.
Can I remove and reuse the valve?
While the fittings are designed for ease of installation, it is generally recommended to use a new valve if you notice wear on the O-rings during removal.
Is this valve compatible with plastic piping?
This valve is designed for use with standard 15mm pipe; check that your specific plastic pipe manufacturer permits the use of standard push-fit valves.
What does WRAS approved mean?
It means the product complies with the Water Regulations Advisory Scheme, ensuring it will not cause contamination to the water supply.
Troubleshooting
Valve is leaking at the push-fit connection
Remove the pipe, check that the end is perfectly round and free of burrs or scratches, then re-insert firmly.
Handle is stiff and hard to turn
Ensure the valve is not under excessive mechanical stress from pipe misalignment; if the issue persists, check for limescale buildup.
Pros and Cons
Pros
- Tool-free installation saves significant time
- WRAS approved for safety compliance
- Compact design fits into tight spaces
- Quarter-turn handle for quick operation
Cons
- Requires clean, burr-free pipe ends to prevent leaks
- Less permanent than soldered joints
- Not suitable for non-standard pipe sizes
Setup, Compatibility & Care
To install, ensure the 15mm pipe is cut cleanly and that all edges are de-burred to protect the internal O-ring seal. Once the pipe is prepared, push it firmly into the valve until it reaches the stop point. No additional sealing tape is typically required, but ensure the pipe is fully inserted. For care, keep the valve free of debris during installation and periodically cycle the valve handle once or twice a year to prevent mineral build-up, which can lead to stiffness in hard water areas.
