The Prima Plus Dzr Compression Adaptor is designed for plumbers and DIY enthusiasts needing a reliable brass fitting for water and gas installations. Its key benefit is guaranteed quality and safety, manufactured in Britain to stringent EN 1254 standards and WRAS approved. A potential caveat for some users might be the specific size (42mm x 1.1/2" Male) which requires precise application matching.

WRAS (Water Regulations Advisory Scheme) approval means the fitting has been tested and complies with the Water Supply (Water Fittings) Regulations 1999 in the UK. This ensures it is safe for use in contact with drinking water and will not contaminate it.
Yes, this fitting is suitable for use with natural gas installations, provided it is installed according to all relevant gas safety regulations and standards.
DZRs stands for Dezincification Resistant. This type of brass alloy is formulated to resist the leaching of zinc when in contact with water, which enhances its durability and longevity, especially in potable water systems.
You will need two wrenches: one to hold the fitting body steady and another to tighten the compression nut. Ensure the wrenches are the correct size for the nut and fitting.
Compression fittings, like this adaptor, use mechanical seals created by compressing an olive onto the pipe. Soldered fittings create a seal through melting and fusing metal. Compression fittings do not require heat and are generally easier for DIY installation.
After hand-tightening, typically tighten an additional 1/2 to 3/4 turn with a wrench. Overtightening can damage the olive or pipe, while under-tightening can lead to leaks. Refer to specific installation guides for precise torque recommendations if available.
Check that the olive is correctly seated and that the compression nut has been tightened sufficiently. Ensure the pipe is not damaged and is inserted fully. If the issue persists, the olive or fitting may be faulty, and replacement may be necessary.
Ensure threads are clean and free from debris. If the nut is cross-threaded, it must be removed and the threads inspected for damage. If it's a matter of resistance, ensure you are using appropriate tools and applying steady pressure.
While DZRs brass offers resistance, prolonged exposure to aggressive water conditions can still cause issues. Inspect the connection and consider if water treatment is necessary for your system.
