connections may be accomplished using a fabricated
reducing fitting, saddle tee, "Insert-A-Tee", or UNI-T.
Fabricated reducing fittings are installed using
normal installation procedures for the joints specified.
Saddle tees are split couplers with a Dual Wall stub
welded onto the center of the coupler. A half circle
approximately 1" larger than the nominal stub diameter
should be cut into each pipe end of the main line.
The pipes should be aligned with the saddle tee
wrapped around the pipe and secured with nylon ties.
connections may be made at locations along the length
of the pipe. Installation of an "Insert-A-Tee" should
follow the manufacturer's recommendations. In general,
the installation involves marking the location of
the tap. A hole is cored using a core drill sized
for the "Insert-A-Tee". A neoprene boot and PVC
stub are inserted in the hole and a gasketed Dual Wall pipe is inserted.
|UNI-T is similair to "Insert-A-Tee" in that it is a tap connection that can be placed along the length of the pipe. Installation of the UNI-T should follow the manufacturer’s recommendations. In general once a hole is cored the UNI-T is inserted and held in place by removing the appropriate number of rings or shims.
