Water Services Association of Australia (WSAA) is pleased to announce the publication of WSA 134 Tapping Ferrules

Title:                                   WSA 134 Tapping Ferrules

Version:                              1.0

Publication date:             April 2023

This standard was prepared by a Water Services Association of Australia with support and guidance from a WSAA Working Group comprising representatives from Reliance Worldwide Corporation Limited, Iplex Pipelines Australia Pty Limited, Strongcast Pty Ltd, Wenac Australia Pty Ltd and Greater Western Water.

The objective of this Standard is to provide a specification for tapping ferrules commonly utilised in water supply pipelines.

This Standard specifies requirements for PN 16 standard tapping ferrules and pressure tapping ferrules (TPFNR) in sizes DN 20, DN 25, DN 32, DN 40 and DN 50 that may be utilised with mechanical tapping bands to facilitate connection of house services to watermains.

Standard tapping ferrules are suitable for dry tapping applications and provide a means for isolating flow at the tapping point.

Pressure tapping ferrules incorporate an isolating tapered plug or ball valve to facilitate tapping into a live main. A means for isolating flow at the tapping point is also provided.

Both ferrule types have a clockwise closing rising stem and incorporate a jumper valve device to prevent backflow of water where loss of pressure in the main is encountered.

Both ferrule types may also be supplied with a cap to replace the bonnet assembly containing the flow isolation facility.

The WSA 134 Tapping Ferrules can be accessed via the WSAA Shop .
