When there is no access to the plumbing from below, Schluter-KERDI-DRAIN is installed to
the appropriate height and connected to the waste line prior to the installation of the
shower base. This can be done in conjunction with the Schluter-KERDI-SHOWER
prefabricated tray (PAUSE)…or a mortar base. The plumbing is in place and must be secured
prior to installation. First, let’s demonstrate the process using
the KERDI-SHOWER tray. The center section can be removed and used to establish the appropriate
elevation of the KERDI-DRAIN. Dry fit the drain flange and measure and cut
a section of pipe to connect the KERDI-DRAIN to the odor trap below the floor.
Assemble the components and verify the fit. You can also use the foam spacers included
with the drain. They are designed to position the drain at
the appropriate elevation. This can be advantageous on projects where
the KERDI-SHOWER trays may not be installed immediately.
Prepare the odor trap cut section of pipe, and KERDI-DRAIN with cleaner, primer, and
ABS or PVC cement per the solvent cement manufacturer’s instructions.
Attach the cut section of pipe to the drain… …and connect the assembly to the waste line
using a twisting motion. Apply thin-set mortar to the substrate…
Then apply it to the top and bottom of the detached center section of the shower tray.
Slide the center section into place under the drain (pause) to ensure solid and uniform
support of the bonding flange. Clean away excess mortar.
Check the drain for level. The KERDI-SHOWER tray and waterproofing accessories
can now be installed. Now we’ll demonstrate the installation with
a mortar base. You will need to set the drain to the appropriate
elevation using shims. Keep in mind, that over wood substrates, the
minimum thickness of mortar required at the perimeter of the bonding flange is 1 inch
(PAUSE)… Prepare and connect the plumbing as shown
previously. Next, pack loose mortar under the drain up
to the inlet hole to ensure solid and uniform support of the bonding flange.
Check the drain for level. The screed is then placed flush with the top
of the bonding flange of the KERDI-DRAIN and work on the shower assembly may continue.
The integrated Schluter-Shower-System ensures success (PAUSE) and makes shower installation
