Not included in kit SKU.
(Material can be Cast Iron, ABS, or PVC)

Site Sizable PVC Linear Drain kits DO NOT
include a mechanically fastening clamp down drain.
Infinity Drain offers a compact clamp down floor drain with a smaller footprint that allows the installation of linear drains flush against the wall. (Shown in step 1)
Add Clamp Down Drain:
CDA 22 Clamp Down Drain ABS
CDI 22 Clamp Down Drain Cast
Iron
CDP 22 Clamp Down Drain PVC 2” CLAMP DOWN DRAIN
**NOT INCLUDED IN KIT

** For installations not flush against the wall a standard clamp down drain may be used, which is available from your local plumbing supply from various manufacturers (Oatey®, Sioux Chief™, JSC™, Matco-Norca™)

Note: Installer must verify all rough-in dimensions prior to installation and consult local and national codes. Conformity and compliance to local and national codes are the responsibility of the installer.

INSTALLATION INSTRUCTIONS

INSTALL THE DRAIN BODY

STEPS 1B,C,D ARE ONLY APPLICABLE TO INFINITY DRAIN’S COMPACT CLAMP DOWN DRAINS (CDI 22 | CDP 22 | CDA 22)

A. Determine the location of the drain outlet location. Typically linear drains span a dimension from wall to wall, against a wall or at a shower entrance.
Installation Instructions
B. If clamp down drain body is not installed, use the template and mark the centers of the holes through the paper, and prepare to drill the holes. (Copy of template printed on back cover)

C. Drill the four 1-1/8” outer circles first.

D. Drill the 3-1/2” circle last, and ensure the drain body fits into the cutout.

E. Attach to existing waste line and allow drain body to recess into subfloor. Ensure that drain body is level. Unscrew and remove top clamp down plate from drain body.

Note: If NOT using Infinity Drain compact drain body and install is required to be flush against the finished wall, build out wall with backer board over round clamp down drain body to compensate for the drain radius.

SPREAD PRIMARY MORTAR BED

A. Spread a primary mortar bed across the intended shower area. Pitch this bed in all directions towards the drain body.

WATERPROOF

A. When mortar layer is dry, perform necessary waterproofing (PVC Liner, CPE Rubber Liner/Chloraloy™, Lead Pan, Copper Pan, Hot Mop, Fiberglass) as per local code. Ensure waterproofing layer reaches the edge of the hole in the drain body. Reattach the top clamp down plate to the clamp down drain body over the waterproofing layer using bolts.

ASSEMBLE PVC COMPONENTS

A. Measure desired wall to wall length, allow for wall tile thickness and 3/16” for both end caps. Cut PVC channel to desired length.

B. Account for the 2-7/16” outlet section along channel length.

C. Cut the sized PVC channel at the desired location of the outlet section. Insert the open ends of the PVC channel into the slotted ends of the outlet section. Dry fit PVC channel and outlet section before affixing. Affix with clear PVC primer and PVC cement.

D. Dry fit end caps over the open ends of the channel before affixing. Affix the end caps to the channel using clear PVC primer and PVC cement.

INSTALL CHANNEL TRIM (OPTIONAL)

A. Measure the inside length of the assembly, and mark the measured length on the outside edge of the channel trim.

B. Using a pair of metal cutting snips, first cut the longer side of the channel trim at the previously made mark. Then make a second cut along the short side and bend the channel trim back. Make a final cut along the bend. File down any rough edges

C. Insert one end of the channel trim over one of long edges of the PVC channel assembly at a 20°-30° angle with the longer side on the inside of the channel. Once this end is inserted, bring the channel trim flat down on to the top of the channel edge and lightly tap down over the edge using a rubber mallet or equivalent. Repeat this procedure for the other long edge of the PVC channel assembly.

INSTALL LINEAR DRAIN CHANNEL

A. Screw threaded nipple into top clamp down plate of the drain body. Adjust to the desired height. Turn clockwise to lower, counter-clockwise to raise.

Note:
Do NOT affix channel or outlet section to threaded nipple until step 6B.

B. Test fit the combined PVC channel for desired height onto the threaded nipple. Affix the threaded nipple to the underside of the combined PVC channel using clear PVC primer and PVC cement

CHANNEL SPACER

A. After PVC cement is dry, measure and cut the channel spacer to the inside length of the PVC channel assembly. Insert the channel spacer into the channel assembly during mortar and tiling to prevent channel flexing. Ensure spacer sits firmly into channel assembly and over channel trim.

LEVEL THE CHANNEL

A. Create a mortar bed the length of the channel assembly on top of the waterproofing membrane. Backfill the underside of the channel assembly and ensure it is level. Use necessary amount of mortar to adequately support the channel assembly. During installation, ensure that the weep holes in the clamping ring are free of any obstructions or debris using pea gravel or equal.

Note:
Site Sizable® models are designed with a finished neutral internal pitch. With proper ventilation of waste line plumbing, the fluid of the charged channel will find any point of exit by force of gravity.
Negative pressure below the drain level will create a vacuum to aid in the siphoning action through the drain outlet. Based on Manning’s Equation the designed depth of the channel has been optimized for the specified flow capacity.

SPREAD FINAL MORTAR BED & TILE

A. Using desired floor material, mark thickness of the material along the channel so that finishing material will finish 1/16” above the channel.

B. Lay final mortar bed across the wet area. Pitch this bed in one plane toward the linear drain. Ensure that the weep holes in the clamping ring are free of any obstructions or debris using pea gravel or equal. Allow space for thinset and tile so that tile finishes 1/16” above the channel. After dry, apply a bead of silicone caulk around the channel. Lay thinset and tile, finish tile work to the edge of the combined PVC channel. DO NOT allow tile to finish over and/or on the PVC channel.

COVER VISIBLE PVC EDGES (OPTIONAL

A. To cover the visible edge of the PVC channel (G), use a fine sandpaper to rough the channel’s top edge. Use a bead of a epoxy based silicone that this similar in color to the finishing grout OR Use a 1:1 mixture of clear PVC cement and desired dry unsanded grout, and apply immediately along the visible edge. Clear PVC primer solvent should be used on the channel edges before applying PVC/grout mix.

INSTALL LINEAR DRAIN GRATE

A. After tile and grout are complete, remove the channel spacer.

B. Measure and cut the top grate (A) to a ⅛” less than the inside length of the channel (to allow for grate removal) using a hack saw with a 32 tooth blade, band saw or miter saw with carbide tipped blade with at least 90 teeth. Gently file back the rough edges.
