Extended Product Information

FAQs

What type of pipe does this stopcock fit?

This stopcock is designed for 32mm MDPE (Medium Density Polyethylene) pipes. It also has compression ends suitable for connecting to copper pipes.

What does DZR brass mean?

DZR stands for Dezincification Resistant. This means the brass alloy is formulated to prevent the leaching of zinc when exposed to water, which enhances its durability and resistance to corrosion, especially in various water conditions.

What is the BS 1010 standard?

BS 1010 is a British Standard that specifies requirements for stopvalves, taps, and fittings. Compliance ensures the product meets safety, performance, and quality benchmarks for water control devices.

Can I use this stopcock with PVC pipes?

No, this stopcock is specifically designed for MDPE polyethylene pipes and copper pipes. It is not compatible with PVC pipes.

How tight should I make the compression nut?

Tighten the compression nut firmly by hand, then use a wrench to tighten it an additional 1/2 to 3/4 turn. Avoid overtightening, as this can damage the pipe or fitting and cause leaks.

What is the maximum pressure rating for this stopcock?

This stopcock is intended for standard domestic water pressures. Specific high-pressure applications may require specialized valves rated for those conditions.

Do I need special tools to install this stopcock?

You will need appropriate wrenches to tighten the compression nuts. A pipe cutter and possibly a deburring tool are also recommended for preparing the pipe ends.

Troubleshooting

Stopcock is leaking from the compression fitting.

Ensure the pipe end is clean and free from damage. Check that the compression nut is tightened correctly (hand tight plus 1/2 to 3/4 turn). If the leak persists, the olive or pipe may be damaged, requiring replacement of the affected section.

Difficulty connecting to the pipe.

Verify you are using the correct size (32mm) and type (MDPE) of pipe. Ensure the pipe end is cut square and is not deformed. Warm the pipe slightly in cold weather if it is too rigid.

Stopcock is stiff or difficult to turn.

Ensure no debris has entered the valve mechanism. Operate the valve back and forth a few times. If stiffness persists, professional assessment may be needed, but avoid forcing it excessively.

Stopcock does not shut off water completely.

Check for debris lodged in the valve seat. Turn the water off and on at the main supply, then operate the stopcock again. If the issue remains, the valve may be worn or damaged and require replacement.

Pros and Cons

Pros

  • Ensures secure and leak-free connections to MDPE pipes.
  • DZR brass offers excellent corrosion resistance for longevity.
  • Compliance with BS 1010 standards ensures reliability and safety.
  • Versatile for connecting both MDPE polyethylene and copper pipes.
  • Provides dependable water flow control for plumbing systems.

Cons

  • Specific compatibility with 32mm MDPE polyethylene pipes means it's not a universal fit for all pipe types or sizes.
  • Requires appropriate tools for compression fitting, which may not be readily available to all DIY users.
  • Brass fittings can be susceptible to damage if overtightened during installation.
  • Not suitable for applications requiring specific high-pressure ratings beyond standard domestic use.
  • Requires a clean pipe surface for optimal compression seal.

Setup, Compatibility & Care

Setup:

  1. Ensure the water supply is turned off before installation.
  2. Clean the end of the 32mm MDPE pipe and the copper pipe (if applicable) to ensure a smooth surface for the compression fittings.
  3. Slide the compression nut and then the olive onto the MDPE pipe.
  4. Insert the stopcock body into the MDPE pipe end.
  5. Slide the olive onto the tapered end of the stopcock body.
  6. Tighten the compression nut firmly by hand, then use a wrench to tighten it an additional 1/2 to 3/4 turn. Overtightening can damage the pipe or fitting.
  7. Repeat for the copper pipe connection if applicable, using appropriate fittings for copper.

Compatibility:

  • Designed specifically for 32mm MDPE (Medium Density Polyethylene) pipes.
  • Compatible with copper pipes when used with appropriate compression fittings for copper.
  • Suitable for cold and hot water systems within standard domestic pressure ranges.

Care:

  • Periodically check the compression nuts for tightness, especially after initial installation.
  • Avoid exposing the stopcock to excessive external force or impact.
  • No regular maintenance is typically required for DZR brass stopcocks under normal operating conditions.
