LUCIE COUNTY BOCC H N l `M�ln LeViA 12MY2021 shower Pan Liner APPLICATION IWSTRUCT4�OfdS Tile Shower Drain Strainer 094W�) Adjustable Drain Barrel Reversible Clamping Ring Drain Base Oatey provides several products needed for the shower installations. Choose from the list below before you start your project PVC or CPE Pan Liner — referred to as pan liner or membrane in our instructions. Tile Shower Drain — PVC for PVC drain pipe or ABS for ABS drain pipe. Each is Collar available with stainless steel, polished Bolts brass or white plastic strainer. Shower Pan Installation X-15 or CPE (I ateMeldJ bonding adhesive — For use on dam corners or seaming use X-15 for PVC and Oateyweld for CPE. PVC'&ABS solvent cement — PVC solvent cement and primer for PVC drainage systems or ABS solvent cement for ABS drainage systems. Use the appropriate cement (and primer for PVC) to solvent weld; tile shower drain to the drain pipe. 1. For typical wood subfloor cut a 4.5" diameter hole in the center of the shower floor where the tile shower drain would normally be positioned. Disassemble the tile shower drain. Lay the tile shower drain base in the opening' so the flange of the drain base rests on top of the subfloor. Solvent weld the drain base to the drain pipe using the appropriate solvent cement. See Figure A. Figure A Dam Corners — For outside corners and over the curb preformed dam corners are available, which can be used for PVC or CPE pan liner applications. Note: Oatey pan liner instructions assume the shower framing has been constructed and the flooring is plywood. Generally the same principles apply to concrete flooring where the sloped mortar bed is applied beneath the pan liner. Also the instructions apply to either PVC pan liner or CPE pan liner which are installed the same with the exception of the bonding adhesive used for seaming and dam corner applications. If you have questions regarding pan liner installation that are not covered in these instructions, contact Oatey customer service at 800-321-9532 and you will be referred to someone who can assist you. 2. Cover the drain base opening with duct tape to keep debris from entering the drain. Begin by applying Portland Sand/ Cement mixture mortar bed over the subfloor at 1/4" per foot slope from the wall framing to the top of, but not over, the drain base. After this step the sloped mortar bed should be flush with the top surface of the drain base. 3. After the sloped mortar bed has cured, the pan liner dimensions need to be determined. Pan liner dimensions should be sufficient to completely cover the floor, turn up all sidewalls at least 2" above the finished curb height, and adequately cover the curb. Lay the pan liner on a Figure 8 clean floor surface,-1 measure, and cut to the appropriate dimensions. ` Note: Seaming may be required in larger showers. - See Figure B. Follow instructions on bonding adhesive. M 4. Before installing the pan liner remove the jape from the drain base and apply a 1/4"-3/8" bead of 10N6 silicone caulk around the upper surface of the drain base approximately 1" in from the outside edge. This will provide a,seal between the underside of the pan liner and the drain base surface. Screw the clamping ring bolts into the drain base to 2-3 thread depth. Before the caulk dries lay the premeasured pan liner on the floor and over the drain body. At the top of each bolt slit an "X" so the pan liner slides over the bolts and down to the drain base surface. Press pan liner firmly'into place to ensure a seal between the drain base and the bottom surface of the pan liner. 5. Work the pan material from the drain bodylto the sidewall framing and curb threshold so it lays flat on the floor surface. If desired an adhesive can be used to bond pan liner to the floor and curb. Prior to use of adhesive, confirm, compatability of adhesive to the pan liner. Fold corners andlnail or staple pan liner to the sidewall framing or wall studs 1/2" below the upper edge of the material 'k Nairar Staple to hold it in place. Nail or Figure C staple the remainder of the - pan liner to the sidewall framing or wall studs 1/2"!' below the upper edge of the s material. See Figure C. - -,:- 6. For outside corners or Figure D curbs where it's necessary to cut the pan liner use a dam corner to cover the cut area. To bond dam' corners in the cut area use X-15 for PVC liner installations or Oateyweld for CPE liner installations. .,. See Figure D. 7. Locate where the drain hole is on the drain base and cut out the pan liner material to the dimension of the drain hole on the drain base. Place clamping ring over the bolts and slide the ring counter clockwise .so it's locked in place. Tighten the bolts so they're snug. Make sure the weep holes are clear of any residual pan liner material or silicone. Note: The clamping ring can increase the height of the finished shower floor by approximately 3/4". You will see the extension if you turn the ring upside down. Simply tighten it to the drain base the way you normally would,, only inverted. 8. Water test the installation by closing off the drain pipe opening with a pneumatic or mechanical test plug. Fill the shower floor with water just below the top of the curb and let it sit for four (4) hours. Observe for leaks and repair if necessary. Retest the installation. Repeat until the installation is leak free. Completely drain the water before proceeding to Step 9. 9. A reinforcement bed of mortar needs to be applied over the membrane (see step 11) but before doing so nail water impervious drywall to the wall studs to approximately 1" above the pan liner surface. Note: The use of mortar vs. drywall for the curb should be considered because you can avoid the use of nails as you construct this part of your installation. 10. The clamping ring has an inner thread pattern that will accept the drain barrel and strainer assembly. Once you determine the finished height of the shower thread the drain barrel into the inside clamping ring thread so the finished floor will be flush with the top of the drain barrel. As mentioned in step 7 you can increase the shower drain height by inverting the clamping ring. 11. Before the final mortar Figure E application place some pea gravel over the weep holes so the mortar doesn't completely cover them. m Now lay the minimum 11/2" R~ ' reinforcement mortar bed of concrete over the pan y - liner from the wall to the drain barrel, leaving enough` room for the final thinset = and tile application.
