S.C. <- service clamp required

D.T. -~ Direct Tap

The service clamp required for P.V.C. pipe must provide
full support around the circumference of the pipe, i.e.
U-Bcolt type that we now use for Del. pipe is nor
compatible. The Robar Series 2706 service sadd!2 with
approximately 50 mm wide strap width is recommended for use
with P.V.C. C-900 pipe.

AWWA threads are recemmended for direct tapping operations
on P.V.C. Pipe, not iron pipe thread. City of Port
Coquitiam's Del. tapping machine taps with AWWA threads and
is a recommended tapping machine for P.V.C. pipe. The City
has previously purchased a special core cutter for P.V.C.
pipe which is suitable for future use although it is
imperative for proper taps thar the core cutters be
replaced once they become dull.

On F.eV.Cew plpe the corporation stops should be located a
minimum of 300 mm from the pipe end. Multiple corporation
stop insertions should be staggered as wel! as separated by
a minimum of 300 mm.
