This Primaflow 15mm black lever-operated ball valve is designed for plumbers and DIY enthusiasts needing a reliable inline shut-off solution for 15mm copper pipes. Its key benefit is maintaining full water flow when open due to its full-bore design, preventing pressure loss. A minor caveat is that the black finish, while aesthetically pleasing, may show water spots if not dried properly.

This valve is designed for 15mm copper pipes, with 15mm compression fittings on both inlet and outlet.
No, this valve is specifically designed and rated for water systems only. It is not suitable for gas lines.
The valve comes with removable red and blue bands that can be attached to the lever to visually indicate hot (red) or cold (blue) water systems.
No, this is a compression fitting valve, meaning it installs onto the pipe using nuts and olives, without the need for soldering.
A full flow ball valve has an internal bore that matches the diameter of the pipe, ensuring that water flow rate is not reduced when the valve is fully open, thus maintaining system pressure.
The chrome-plated brass body can be cleaned with a soft, damp cloth. Avoid using abrasive cleaners or scouring pads, as these can scratch the finish.
While specific lifespans vary based on installation and usage, brass valves with compression fittings are generally durable and long-lasting when installed correctly and used within their specified limits for water systems.
Ensure the compression nuts are tightened sufficiently. Check that the olives are correctly seated and that the copper pipe ends are smooth and round. If the leak persists, the olive or fitting may be damaged and require replacement.
Check for any debris or obstructions around the valve body or lever. Ensure the valve is fully open or closed before attempting to turn the handle. If it remains stiff, a small amount of appropriate lubricant may be applied to the valve stem, but avoid over-lubrication.
Verify that the valve is indeed a full-flow type and that the lever is in the fully open position (handle parallel to the pipe). Ensure no other restrictions exist in the pipework downstream of the valve.
Setup: This valve is designed for inline installation on 15mm copper pipe. Ensure the pipe ends are clean and free from burrs. Slide the compression nut and then the olive onto the pipe. Insert the pipe into the valve end and tighten the compression nut firmly using two wrenches – one to hold the valve body and another to tighten the nut. Repeat for the other end. Turn the lever handle to test operation. Ensure the red or blue bands are correctly fitted if distinguishing between hot and cold is desired.
Compatibility: Suitable for use with 15mm copper pipes. It is rated for both hot and cold water systems. Always ensure the system pressure and temperature are within the valve's operating limits.
Care: Periodically check compression fittings for tightness, especially after initial installation and temperature fluctuations. Keep the lever mechanism free from debris. The chrome-plated brass body can be cleaned with a damp cloth; avoid abrasive cleaners.
