Product Information
Full details
The Primaflow QQL Iso Valve Tee is an essential plumbing component for residential and light commercial systems, ideal for professionals and DIY enthusiasts looking to manage water flow efficiently. Its primary benefit is providing a reliable, quick-action isolation point for maintenance or emergency repairs. While it is engineered for standard 15mm piping and provides excellent durability, users should ensure the system pressure aligns with the valve's technical ratings before installation to prevent premature wear.

FAQs
Is this valve suitable for central heating systems?
Yes, it is designed for use in standard domestic plumbing, including many water-based heating applications.
Can I install this on copper or plastic pipe?
It is designed for standard 15mm copper piping. If using plastic pipe, ensure you use the correct pipe insert to maintain rigidity.
What does WRAS approved mean?
It means the product has been tested to meet the high standards required by UK water regulations for safety and quality.
Does this valve come with olives?
Yes, standard compression fittings of this type typically include the necessary nut and olive for installation.
Can I leave this valve partially open to control flow?
It is designed as an isolation valve. It should be used in either the fully 'on' or fully 'off' position to prevent wear on the internal seal.
Troubleshooting
The valve is leaking from the compression joint
Ensure the pipe is pushed fully into the fitting and tighten the compression nut slightly further.
The lever is difficult to turn
Check for mineral deposits and gently flush the area or apply a small amount of silicone-based lubricant.
Water continues to flow even when the valve is closed
Verify that the valve is fully in the 'off' position and check for debris trapped in the ball mechanism.
Pros and Cons
Pros
- High-quality chrome plated finish for aesthetics and corrosion resistance
- WRAS approved for peace of mind regarding water safety
- Compact form factor ideal for restricted installation spaces
- Simple lever mechanism allows for intuitive operation
- Reliable isolation prevents flooding during maintenance
Cons
- Limited to 15mm piping systems only
- Requires proper compression fitting techniques to prevent leaks
- Not suitable for high-pressure industrial applications
Setup, Compatibility & Care
To install, ensure the 15mm pipe is cut cleanly and deburred before inserting it into the valve compression nut. Tighten the nut firmly, but take care not to over-torque, as this can damage the internal seal. For optimal care, it is recommended to operate the lever through its full range of motion at least twice a year to prevent mineral build-up within the valve body. Avoid using abrasive cleaning agents on the chrome finish; a damp microfiber cloth is sufficient to maintain its appearance and structural integrity.
