Z1035 and Z1036 FLOOR DRAIN INSTALLATION STABILIZER For Flying Form Construction
The Zurn Drain Installation Stabilizer is a unique support plate designed to secure a drain in place and provide adjustment, rigidity, and
strength during the drain installation process.
The main objectives for the Drain Installation Stabilizer are as follows:
a) To provide a means of pre-assembling the drain to a known
rough-in height. If the floor thickness is already known, the drain
and Installation Stabilizer can be conveniently pre-assembled
away from the job site, and quickly placed and leveled in the
correct location at the job site, saving labor costs.
b) To locate and secure the drain in place and keep it in position
prior to concrete pour. The Installation Stabilizer will help resist
the drain from tipping, tilting, or being knocked over during
construction and concrete pour.
c) To allow height and level adjustments of the drain to meet the
finished floor.
d) To support any reasonable excess weight that may be placed on
the drain before the concrete is poured.
e) To create an open pocket on the underside of the plate, allowing
for attachment of the waste line piping after a concrete pour.
How To Use the Drain Installation Stabilizer
The Installation Stabilizer is constructed of galvanized steel plate and is designed to be used with 8-3/8" diameter, 12" diameter, and 15"
diameter drain bodies (2", 3", and 4" No-Hub and Neo-Loc outlets).
Four lengths of all-thread rod are attached to the drain body by inserting and tightening into the tapped holes located on the underside of the
drain body. The stabilizer plate is then connected to the all-thread rod by use of flanged nuts, above and below the plate. Adjusting the
placement of the nuts changes the rough-in height of the drain. Once the proper height is obtained, the nuts are tightened against the plate.
Any excess rod is trimmed off and a stub of pipe is then connected to the drain body and allowed to extend through the center hole of the
plate. The assembly is then nailed down to the concrete form.
When concrete is poured around the drain, the plate creates a pocket on the underside of the slab. When the concrete is set and the forms
are stripped away, the visible result is a stub of pipe protruding through the underside of the slab. The remaining drain line can then be
connected to this stub of pipe.

Z1036 (For 12" and 15" diameter drain body.)

FLOOR DRAIN INSTALLATION STABILIZER Assembly Instructions
Step 1 Connect a shielded coupling to the drain body (No-Hub
connection), or insert gasket into drain body (Neo-Loc
connection).
Step 2 Remove the threaded studs from hardware bag (Part Number
66955-312-9) and screw into the tapped bosses on the
underside of the drain body until tight.
Step 3 Screw one flanged nut onto each stud with the flange facing
downward.
Step 4 Insert the studs through the four holes of the plate with the
plate cavity facing downward. Set the drain body at the
required rough-in height and screw the flanged nuts down
until they are flush against the top of the plate.
Step 5 Screw the second flanged nut onto each stud with the
flange facing upward. Tighten both nuts on each stud until
the plate is secured to the studs.
Step 6 Trim the studs down so they are flush with the bottom of the
plate. Set the assembly onto a level surface and check to
ensure that the drain body is level with the plate. The flanged
nuts can be loosened and tightened to allow for any necessary
adjustments. Once leveled, trim any studs that extend beyond
the cavity of the plate.
Step 7 Insert a stub of drainage pipe into the shielded coupling
(No-Hub connection) or gasket (Neo-Loc connection) and
secure. It is important that there be at least 1-1/4" of pipe
protruding through the cavity of the plate in order to make
a connection to the remaining drainage line.
Step 8 Once the assembly is complete and set at the proper
rough-in height, place the assembly in the proper location
prior to concrete pour. The assembly can be nailed down to
the concrete forms by using the nail holes provided on the
rim of the plate.
Step 9 Concrete pour.
Step 10 After the concrete is set and the forms are stripped away,
the result will be a voided area on the underside of the floor
with a stub of pipe protruding through it. Trim off any nails
that are extending beyond the concrete floor. The remaining
drainage line can now be connected to the drain assembly.
Note: Some localities’ building codes do not allow a shielded
coupling or rubber gasket to be buried in concrete. For applications
such as this, a section of 6" PVC pipe can be used to act as a
barrier to keep concrete from coming in contact with the rubber
materials.
