Installation Guidelines:

1. Prepare Pipework: Cut and deburr the MDPE and copper pipes cleanly before insertion.

2. Fit Poly End: Insert the 25mm MDPE pipe into the compression fitting. Ensure the internal pipe support sleeve (not included) is used to prevent collapse.

3. Connect Copper End: Insert 15mm copper pipe into the compression end. Tighten the nut securely using appropriate spanners.

4. Test System: After installation, slowly restore water pressure and check all joints for leaks.

Note: Use appropriate pipe inserts for MDPE to ensure a correct seal and structural integrity. Installation should follow all applicable plumbing regulations.

Care and Maintenance:

• Check Annually: Test the stopcock to ensure it can be opened and closed easily

• Keep Accessible: Ensure the stopcock remains accessible in case of emergency shut-off

• Protect Underground Installations: Use proper housing or inspection chambers for underground use
