Frequently Asked Questions - Devonshire K-3503 KOHLER

How to install the wax ring on the new toilet?

Place the toilet on a padded surface. Firmly press a new wax ring onto the toilet outlet. Then, lower the toilet onto the flange aligning the T-bolts. Apply your weight to seat the seal.

How to adjust the water level in the tank?

Rotate the threaded rod to the right to increase the water level or to the left to decrease it. The level should match the indicated water line.

What to do in case of a leak after installation?

Check all connections. If the connections have been properly assembled, a small additional tightening of the nuts should stop leaks. Flush the toilet several times to confirm sealing.

What tools are needed to install this toilet?

You need: a 10-inch adjustable wrench, a bubble level, a tape measure, a sponge, a putty knife, a hacksaw, and safety glasses.

How to safely remove the old toilet?

First, shut off the water supply. Flush to empty the tank, then sponge out remaining water. Disconnect the shut-off valve, remove the old toilet, and clean the flange with a putty knife.

How to tighten nuts without breaking the porcelain?

Tighten the nuts gently by hand or with a nut driver. Do not overtighten, as excessive tightening can crack or chip the vitreous china.

How to install the tank on the bowl?

Slide the retaining bolts into the bracket at the bottom of the tank. Position the tank gasket over the bowl inlet. Lower the tank centering the gasket, then tighten the nuts alternately on both sides to level.

How to cut the T-bolts if they are too long?

Measure the length from the top of the nuts. If it exceeds 1/4 inch (6 mm), cut off the excess with a hacksaw. Protect the porcelain from blade strikes.

How to flush the toilet after installation?

Slowly open the shut-off valve to check for leaks. Flush several times and inspect all connections. Repeat the process a few days later to verify long-term sealing.

When should you check for leaks after installation?

Immediately after installation, then periodically during the first few days. If leaks appear, slightly tighten the connection nuts.
