Since the early 1990s, plastic municipal service tube has been rapidly replacing copper as the preferred material choice for subdivision construction across North America. This is due to corrosion issues, flexibility and material cost. Designed originally for lead pipe followed by copper piping systems, for many, many years brass valves and fittings have been the natural material choice to connect copper systems – “metal on metal connection”. When plastic piping systems started to be used, the Brass manufacturers all modified their connectors designs to accommodate plastic pipes which resulted in a compromised design to accommodate plastic pipe. You don’t need to do this, there is ample justification for plastic connectors for plastic pipes – “plastic on plastic”. The application of plastic valves and fittings designs to connect plastic pipes is a natural development in the waterworks industry as long as these designs are robust and operator friendly.

At the completion of this one-hour OJT session, participants will be able to demonstrate the following:

                      • The underlying conditions for the design and installation of plastic fitting systems
                      • Reinforced nylon resins for strength and material suitability
                      • Connection design needs recognizing the operators training
                      • Installation criteria which drive plastic valve designs for waterworks applications

  • Facilitators:

    Gerry Gunn

    Our facilitator is Gerry Gunn, Proprietor of Gunn Product Services.  Gerry graduated from the University of Waterloo and is a member of the Professional Engineers of Ontario (P.Eng).  Gerry began working with ARI, an air valve manufacturer in Israel, 17 years ago designing, advising, and installing air valves across eastern Canada.  New air valve designs and direct bury technology development has been at the forefront of this work.  Gerry has been a manufacturer sales agent for over 27 years and recently began representing H-Tec air valves, manufactured by Hawle Coporation of Bertles Garten Germany.  For the last twelve years, Gerry has done air valve CEU training through OWWCO and municipalities at request.


    These 1-hour virtual sessions are offered every alternate Thursday starting at 2:00 pm.  Sessions are complimentary to all OMWA members and the fee for non-members is $30.00 CAD plus HST per person per session.  

    If you have any specific questions regarding this OJT session, please feel free to submit them when you register and we will provide them to the workshop facilitator.   

    The OMWA will provide a certificate recognizing participation in these On the Job Training sessions.
    Attendance may also qualify as a Continuing Knowledge Activity for the PEO PEAK program
