Step 1:
Cut the 1½” Schedule 40 (or Flexible PVC) overflow pipe and drain pipe (
Items 14 and 16
) to the
desired lengths to fit the tub.
Step 2:
Using standard solvent cement procedures, assemble the bath drain pipe and fittings (
Items 13-16, and 19
).
DO NOT LET SOLVENT CEMENT FLOW INSIDE THE OVERFLOW OR DRAIN ELBOWS PAST THE
SOCKET!
Any excess glue will prevent the bath waste from operating.
Step 3:
Place the thick foam gasket (
Item 12
) onto the overflow elbow (
Item 13
).
The testing membrane will still be attached.
Thick-walled tubs will require the
thin gasket (
Item 11
).
Step 4:
Insert the overflow elbow and
foam gasket assembly through the tub
overflow hole from the back of the tub
(
Figure 1
).
Step 5:
Screw on the overflow elbow (OE) nut (
Item 3
)
from inside of the tub (
Figure 2
).
HAND TIGHTEN
ONLY
until the nut is snug and the gasket is only slightly
compressed against the back of the tub.
You must get a
minimum of 1½ turns when installing the nut.
If there are
not enough threads sticking through the tub to get the nut
installed, remove the thick gasket
(Item 12
) and replace it
with the thin gasket (
Item 11
).
Step 6:
Secure the drain elbow (
Item 19
) and drain
flange gasket (
Item 20
) under the tub by screwing
in the strainer body (
Item 21
) through the tub
drain hole from inside the tub (
Figures 3 and 4
).
If desired, a putty or sealant may be used between
the flange of the strainer body and the tub.
CAUTION: Do not use linseed oil based putty
products. Use only thread compounds specifically
intended either for ABS or PVC assembly.
If the bath waste will not be pressure tested, skip to step 8.
Step 7:
Screw the strainer test plug (
Item 26
) into the strainer
body
Item 21
) and test the system (
Figure 5
).
Step 8:
After the pressure testing is complete, remove
the test plug (
Item 26
). Cut away and discard the orange
test membrane from the overflow elbow (
Figure 6
).
Use
caution not to damage internal parts on the inside of the
overflow elbow.
