Frequently Asked Questions - Couture K-3480 KOHLER

How to install the Kohler Couture K-3480 toilet?

Installation requires removing the old toilet, cleaning the flange, placing a new wax ring, positioning the bowl on the T-bolts, then fixing the tank. Gently tighten the nuts to avoid cracking the porcelain. See the manual for complete details.

How to adjust the water level in the tank?

The water level is adjusted by turning the threaded rod of the fill mechanism: turn right to increase the level, left to decrease. The recommended level is indicated by a water line in the tank.

What to do in case of a leak around the base of the toilet?

A leak at the base may come from a poorly installed or damaged wax ring. Remove the toilet, clean off the old ring, and install a new one. Also check that the T-bolts are properly tightened without overdoing it.

What type of wax ring to use for this toilet?

Use a standard wax ring for toilets, suitable for a 3 or 4 inch flange. The manual recommends using a new ring for each installation and not lifting the bowl after placement.

How to maintain the toilet porcelain?

Clean the porcelain with a soft cloth and non-abrasive cleaner. Avoid harsh products (bleach, acids) that can damage the surface. For stubborn stains, use a specific porcelain cleaner.

Can I use an abrasive cleaner on this toilet?

No, abrasive cleaners or rough sponges can scratch and weaken the vitreous china. Use only mild products and non-abrasive cloths.

How to replace the tank bolts?

Remove the nuts and washers under the tank, take out the old bolts, and install new ones. Ensure the gaskets are in good condition and tighten moderately to avoid breakage.

What water pressure is recommended for operation?

The toilet works with standard water pressure (about 3-5 bars). A shut-off valve under the tank is recommended for maintenance. If pressure is too high, install a pressure reducer.

Is the tank compatible with a dual flush system?

The Couture K-3480 model is equipped with a standard single flush. It is not designed for dual flush. If you want to save water, consider an adapter, but check compatibility.

Where to find spare parts for this toilet?

Spare parts (gaskets, bolts, flush mechanism) are available at Kohler dealers or online. Use model number K-3480 to identify compatible parts.

□ Remove the old toilet.
□ Remove the old wax seal from the floor with a putty knife.
☐ Replace the old T-bolts with the new 5/16" diameter T-bolts.

2. Install the New Toilet

☐ Install or relocate the supply and outlet as necessary to conform to the roughing-in dimensions.
□ Install a supply shut-off valve.
□ Lay the toilet down onto a padded surface.
□ From the bottom of the toilet, firmly press a new wax seal around the toilet outlet.
☐ Remove the temporary rag (if used) from the toilet flange hole.
□ Align and lower the toilet over the flange and T-bolts.

IMPORTANT! Do not lift or rock the bowl after placement. If you break the watertight seal, you must install a new wax seal.
