Trough Drain helpful installation hints.

​Installing the Drain ON TOP of The Existing Floor 

1. Place the drain on the floor and up against the wall you want to use to drain the shower (for placement in another location on the shower floor, please call us if you have any questions).

2. Plumb the drain from the bottom discharge opening to a new or existing P-Trap in the floor. Thread a Male Plumbing Adapter (Copper, PVC or Galvanized) into the discharge hole (NOTE: A 2" Compression fitting is also an option). IF POSSIBLE, install the P-Trap so that it is accessible from the basement or crawl space. If you don't have access to the P-Trap from below, you may want to consider a Drain Cover or Drain Grate (See PRICING & GRATES).

3. If you are pouring concrete, place screet guides, for proper slope to the drain, on opposite edges of the shower. Be careful to allow ample slope to the drain (1/4" per foot is ideal). (Allow 24 hours for floor/pan to dry before moving ahead.) 

4. When waterproofing your shower floor on top (rather than the Traditional way, with a Pan Liner), our “Kerdi Glue Flange” works with every type of waterproofing available, from Schluter or Noble Membranes to RedGuard to the Hot Mop or a variety of other waterproofing systems on the market.

5. On the wall with the Trench Drain, please make sure the DuraRock (or similar 1/2" or thicker tile backer board) is flush with or preferably extends beyond the back and side inside edges of the drain.  Leave the bottom of the backer boards about 1/4" above the top edge of the drain so the membrane can be easily applied to the front of the backer board without pinching the membrane.

6. When installing the tile on the back wall, allow the tile to extend into the drain 1/4" to 1/2".

7. When laying the shower floor tile, allow it to come within 1/8”- 3/16" from the tile against the front wall (This will create a sleek, almost unnoticeable line that the water will simply cascade into and disappear). 

NOTE: If you don’t have access to the P-trap from below, please contact David to discuss the options for accessing the drain discharge from above. Much Success!

NOTE: This is the perfect drain for an ADA - Handicapped Accessible Shower!

HELPFUL HINTS WHEN INSTALLING THE TRENCH DRAIN USING

THE TRADITIONAL PAN LINER / RUBBER MEMBRANE UNDERNEATH

1. If possible, install the Shower Barrel Drain that has the Ring Flange, which mechanically attaches to the Rubber Membrane, as close to the center of the wall or floor as you are able.

2. Once this drain has been plumbed and the Pan Liner is in place, proceed with the installation.

3. Lay the Trough Drain upside down and screw in the 2" PVC Nipple (provided with the drain) WITHOUT APPLYING ANY GLUE. The Nipple should come 1/8" below the bottom of the drain. Turn the Trench Drain over to check that the Nipple has been threaded in at the proper depth. 

4. Loosen the 4 Collar Bolts on the Drain Base and remove the Clamping Ring. Thread the Clamping Ring onto the half of the PVC Nipple extending out the bottom of the Trench Drain. DO NOT glue the Clamping Ring onto the threads.

5. Set the entire assembly back on top of the Drain Base and give the Clamping Ring a slight turn to lock it back in place. Tighten all four (4) Collar Bolts on the Clamping Ring to secure it to the Bottom Barrel Drain Assembly. Make sure the Trench Drain is parallel to the wall before you proceed with your pour. 

NOTE: If you are using existing plumbing and the Shower Drain is cast iron, the Collar Bolts will need to be completely removed before the Clamping Ring can be removed. Care needs to be given not to allow the Pan Liner to move around when the Clamping Ring and Collar Bolts have been removed and while replacing.

6. With everything in place and secured you are now ready to continue as usual and pour the shower pan. The biggest difference is that the Shower Pan will be one flat plane sloping gently to the top front edge of the Trench Drain. You will find it much easier pouring a flat single plane surface rather than one that has four (4) different slopes, all to the center. Your tile job will be much easier and quicker also.
