Install The Plumbing - Kohler Fountainhead K-1786 Installation Manual

4. Install the Plumbing

NOTE: Provide access at the back of the plumbing wall for servicing the supply and waste piping.
Locate rough plumbing for the drain according to the correct model's roughing-in dimensions.
Position the plumbing according to the roughing-in information.
Cap the supplies and check for leaks.
Install a 2" (5.1 cm) diameter drain line to extend 3/8" (1 cm) above the subfloor or slab. A pocket is
required in a slab construction to accommodate the drain fitting.
Install the shower valving according to the manufacturer's instructions. Do not install the trim at
this time.
If installing a steam system, position the rough plumbing for the steam head at the intended
installation location at this time. Refer to installation instructions packed with your steam
components for details.
5. Prepare the Receptor
CAUTION: Risk of product or property damage. If a watertight seal on the drain is not obtained,
water damage to the receptor bottom and the subfloor may occur.
Install the drain to the shower receptor according to the drain manufacturer's instructions. Follow
all local building codes, standards, and regulations.
Clean the shower receptor to reduce the risk of surface damage, then place a clean drop cloth or
other similar material into the bottom of the shower receptor.
6. Position the Receptor
Move the receptor into position. Verify proper fit.
Fit the drain into the trap. Do not connect the trap at this time.
CAUTION: Risk of product damage. If shimming is required, shim between the subfloor or slab
and the wood block feet on the underside of the receptor. All wood block feet must be supported
when the receptor is leveled and nailed to the framing.
Check that the receptor is level in both directions and resting on all feet. Shim if necessary.
Concrete, gypsum cement or other similar materials can be used to level the base.
