Extended Product Information

FAQs

Can this be used on plastic piping?

This stopcock is designed for copper piping. Using it with plastic pipes typically requires a pipe insert to maintain the structural integrity of the joint.

Does it come with olives and nuts?

Yes, the product includes the necessary compression nuts and olives for a 15mm connection.

Can I install this vertically?

Yes, this stopcock can be installed in either vertical or horizontal orientations without affecting performance.

What is DZR?

DZR stands for Dezincification Resistant. It is a type of brass alloy that resists the loss of zinc, which prevents the material from becoming brittle over time.

Do I need plumbers tape for the compression joints?

Compression joints create a seal through the mechanical compression of the olive; therefore, thread tape is generally not required or recommended on the olive itself.

Troubleshooting

Water weeping from the compression joint

Ensure the pipe is cut square and is free of debris. Tighten the nut slightly more, but do not overtighten, as this can damage the olive.

Valve handle is difficult to turn

Gently wiggle the handle to break up minor mineral deposits. If it remains stiff, check for debris or check if the valve has been forced in the past.

Water continues to flow when valve is off

Verify that the valve is fully rotated to the closed position. If it still leaks, the internal seal may be compromised by debris and may require inspection or replacement.

Pros and Cons

Pros

  • Resistant to dezincification for increased lifespan
  • Easy installation using standard hand tools
  • No soldering required for assembly
  • Provides a positive water seal

Cons

  • Not intended for non-copper piping materials
  • Requires proper tightening to prevent compression leaks
  • Fixed 15mm size limits use in larger diameter mains

Setup, Compatibility & Care

To install the Plumbright Stopcock, ensure your water supply is completely turned off at the mains before cutting into the pipe. Ensure the copper pipe ends are clean, burr-free, and perfectly round. Slide the compression nut and olive onto the pipe before inserting the pipe into the stopcock body. Tighten the nut by hand until firm, then use a wrench to tighten by an additional half to three-quarters of a turn. Over-tightening can deform the olive and cause leaks. Periodic checks should be performed to ensure there are no signs of weeping at the joints, and the valve handle should be operated once or twice a year to ensure it remains free-moving.
