The Reliance Valves DZR Brass Ball Valve (15mm) is designed for professional plumbers and DIY enthusiasts needing a reliable isolation point in water distribution systems. Its primary benefit is the ability to shut off water flow to specific fixtures or localized pipe sections, significantly reducing maintenance downtime by preventing the need to drain an entire building. While the compression-fit design ensures a secure connection, users should be aware that it requires proper pipe preparation to ensure a leak-free seal on copper or plastic tubing.

Yes, but you must ensure you use a suitable stiffener/insert inside the plastic pipe to prevent it from crushing when tightening the compression nut.
Yes, the DZR brass construction is rated for standard hot and cold water plumbing, including central heating applications.
Compression fittings rely on the olive to create the seal. You generally do not need PTFE tape, though a light application on the threads can sometimes assist with smoother assembly.
DZR stands for Dezincification Resistant, meaning the brass is specifically alloyed to prevent zinc from leaching out, which would otherwise weaken the valve over time.
When the handle is parallel to the pipe, the valve is open. When it is perpendicular, it is closed.
Check if the pipe is square and the surface is free of deep scratches. If it continues to leak, replace the compression olive.
Mineral deposits may have built up; cycle the handle slowly several times or use a food-grade silicone lubricant.
To install, ensure the 15mm pipe is cut perfectly square and is free of burrs or scratches, as these can damage the internal olive and cause leaks. Slide the nut and the olive onto the pipe, insert the pipe into the valve body, and tighten the nut firmly using a spanner. Do not overtighten, as this can deform the olive.
Regular care is minimal; simply operate the valve once or twice a year to ensure the ball mechanism does not become seized by limescale buildup. If you are working with plastic piping, ensure you use the appropriate pipe insert to prevent the tube from collapsing under the compression nut's pressure.
