Frequently Asked Questions - Coralais K-15171 KOHLER

What tools are needed to install the Coralais K-15171 faucet?

You will need a Phillips screwdriver, plumber's putty, a hex key, an adjustable wrench, and two 3/8" male supply connectors (included).

How to avoid leaks after installing the faucet?

Make sure to apply plumber's putty under the deck plate and sprayer base, and tighten all nuts securely. Check hoses to avoid severe kinks.

Can I install this faucet on a single-hole sink?

No, the Coralais K-15171 requires two holes: one for the main faucet and one for the sprayer. If your sink has only one hole, you will need to drill a second hole or choose a different model.

How to adjust the maximum water temperature?

Remove the handle and cap, then lift the valve stem. Align the stop tab with the nut to set the max temperature, then turn the indexer and disc a certain number of clicks (each click = 5.3 °C). Close after adjustment.

What to do if water flow is low?

Check that supply hoses are not kinked or tangled. Clean the aerator by unscrewing it and removing debris. Ensure shut-off valves are fully open.

How to clean the Coralais faucet without damaging it?

Use a soft cloth and soapy water. Avoid abrasive, acidic, or ammonia-containing cleaners. Rinse with clean water and dry with a cloth.

Can the sprayer (hand shower) be replaced?

Yes, the sprayer is a separate part. You can order a replacement part from Kohler. Follow the instructions in the manual for removal and installation.

What is the warranty for this faucet?

Kohler offers a limited lifetime warranty for this model, covering defects in materials and workmanship under normal use. See the detailed terms on the Kohler website.

How to know if hot and cold water are connected correctly?

The manual indicates that the left connector is for hot water and the right for cold water. After installation, open the valve and check the temperature at the spout. If reversed, swap the hoses.

Can I use this faucet with a tankless water heater?

Yes, but the water temperature must not exceed 60 °C (140 °F). Check your water heater's compatibility with the recommended pressure and flow (1.4 – 5.5 bar).
