Installation Guidelines - Grooving Pipe
Step 1
Material preparation is essential to achieving satisfactory No-Hub coupling assem-
bly. Pipe must be free of scoring or other surface damage, and should be wiped
down with a clean cloth sprayed with 90% isopropyl alcohol before cutting to
remove cement dust, mud, or other debris that will interfere with the cutter, pipe
grooving tool, or interfere wtih assembly integrity and cause a leak.
Step 2
Cut the cleaned pipe with a thin-wheel plastic pipe cutter to assure a clean, square
cut. Deburr and bevel the cut end of the pipe with a deburring tool. This must be
done prior to grooving the pipe.
Step 3
The grooving tool blade must be fully retracted before use. With the grooving tool
handle pointing up, turn the small knob on the handle counter-clockwise to the
12:00 position to retract the blade inside the grooving chamber. If unsure whether
the blade is retracted, visually check inside the grooving chamber while turning the
knob: the blade will visibly extend or retract as the knob is turned. Once the blade
is retracted, push the grooving tool onto the pipe end, making sure that the pipe
end bottoms out inside the grooving chamber. The roller ball opposite the blade
assembly can be adjusted using the hex nut, to ensure that the pipe presses tight-
ly against the blade aperture; this is essential to ensure that the groove is uniform
and cut to full depth.
Step 4
Turn the blade adjustment knob another 1/2 turn clockwise to the 6:00 position on
the handle, remembering not to over-torque the knob. Maintaining firm pressure
to keep the pipe bottomed out inside the tool, rotate the grooving tool clockwise
twice around the pipe or until no more material is removed from the groove.
Step 5
Return the blade adjustment knob to the 12:00 position then remove the tool from
the pipe. If the blade is not fully retracted before removing the tool it will score the
pipe end, creating a leak path that will prevent the joint from sealing.
Step 6
Remove all burrs or other material from the groove edges and interior. Ensure that
all excess material is removed from the grooving tool and that the blade is clean
and free of plastic debris before grooving the next piece of pipe.
