Double Check Valve DZR Threaded – Non WRAS

This DZR double check valve is designed to ensure water can only flow one way, also helping to prevent any leaks and protects water supplies from contamination. Threaded BSP double check valves are fast and simple to install, featuring a FI female thread on each end of the fitting and made from quality brass DZR.

For all BSP threaded fittings, we insist that PTFE Tape is used to ensure a leak free joint. We recommend always trying to minimise the amount of joints used on any MDPE water installation wherever possible.

This fitting is not WRAS approved, if you need this approval please check out our WRAS Approved Double Check Valve instead.

If you plan to run any water service underground, we would always recommend that the water pipe is buried in the ground inside a blue water duct system. A duct is designed to protect the pipe from damage and alert others to the presence of duct in the ground. Water caution marker tapes are commonly used as additional indications, alerting presence of the pipes. If this is your first time installing ducting, we would always recommend attaching a second drawcord to your pipe as this will enable you to easily install replacements at any point in the future, if required. Your duct system may also need duct access chambers depending on your project, which come in a various sizes to suit.
