Frequently Asked Questions - Coralais K-15172 KOHLER

How to install the Coralais K-15172 faucet?

Follow the steps: 1) Slide the deck plate over the hoses. 2) Apply putty under the deck plate. 3) Feed the hoses through the sink hole. 4) Center and tighten the nut under the sink. 5) Install the sprayer and connect the hoses to the water supplies (hot left, cold right). 6) Turn on water and check for leaks.

How to adjust the maximum water temperature?

Remove the cap, O-ring, and screw. Remove the handle and bonnet. Lift the valve stem out of the stop tab. Align the tab with the retaining nut for the desired temperature. Turn the indexer and disk (each notch ~5.3°C) to the left to reduce hot. Finally, reassemble the stem.

What to do if water flow is low?

Check that the hoses are not kinked or twisted. Make sure water supplies are fully open. Clean the aerator by unscrewing and rinsing it. If the problem persists, inspect the hose filters.

How to clean the faucet?

Use a soft cloth and mild detergent. Rinse with clean water and dry. Avoid abrasive, acidic, or ammonia-based cleaners that could damage the chrome finish.

The sprayer is not working, what to do?

Ensure the sprayer hose is properly connected to the outlet under the sink. Check that it is not kinked. If the problem persists, the sprayer or hose may be clogged; clean or replace it.

What tools are needed for installation?

You need a Phillips screwdriver, hex wrench, adjustable wrench, plumber's putty, and two 3/8-inch male supply connectors.

Can I install this faucet on an already installed sink?

Yes, but it is recommended to install the faucet before mounting the sink for easier access underneath. If the sink is already installed, you will need space under the sink to tighten the nuts.

How to remove the aerator?

Turn the aerator to the left (counterclockwise) to unscrew it. Clean or replace it. To reattach, screw it to the right.

Is there a warranty on this faucet?

Yes, Kohler offers a limited warranty. See the manual for details. Generally, it covers defects in materials and workmanship for a specified period.

The faucet is leaking at the handle, what to do?

This may be due to a defective cartridge. Shut off water, remove the handle and bonnet, then replace the cartridge (Kohler part). Make sure to tighten the retaining nut properly.
