How to Install a Grohe Ladylux Pro Faucet

Installing a Grohe Ladylux Pro faucet is a bit different from installing a standard faucet. The spout on the Ladylux requires assembly to the faucet body. The spray head installs through the spout and the faucet body. Rather than tightening the mounting nuts from below the sink, the Ladylux Pro uses a special wrench to turn the main spout inside the faucet. The Ladylux Pro also has new water supply hoses that come connected to the faucet body straight out of the box. Although there a some model specific installation details included with each Ladylux faucet, the general installation is the same for all Ladylux models.

Step 1

Find the large o-ring in the faucet kit. Place the o-ring over the threads of the faucet assembly until the o-ring is at the bottom of the housing. The o-ring creates a seal between the bottom of the faucet housing and the sink. Insert the faucet assembly into the faucet hole on the back of the sink with the faucet handle pointing to the right.

Step 2

Ask a friend to go under the sink and slide the brace, washer and connecting nut around the tube of the faucet. The brace looks similar to an octagon. While the helper is holding the nut, insert the round fitting key into the top of the faucet tube. Turn the key clockwise until the faucet assembly is secure to the sink.

Step 3

Go under the sink, and connect the faucet water supply hoses to the house shut-off valves. The blue hose connects to the cold water valve, and the red connects to the hot water supply valve. Wrap plumbers tape around the threads of each valve before attaching. Thread the water supply hoses onto each connection until hand tight. Turn the connections another half turn with a wrench.

Step 4

Feed the spray hose through the faucet spout. Move the faucet spout over to the faucet assembly. Feed the spray hose through the assembly, and push the spout into the assembly until it snaps into place. Connect the rinse spray head to the spout end of the spray hose. The spout head threads onto the spray hose without using any additional plumbers tape.

Step 5

Thread the snap coupling to the bottom of the center faucet tube under the sink until the coupling is hand tight. The snap coupling has a sleeve that pulls back. Pull the snap coupling sleeve back with your fingers, and push the end of the coupling over the end of the faucet tube. Release the coupling sleeve to lock the spray hose to the faucet tube. Turn on the water supply valves.
