Single Handle Bathroom Faucet Installation Single Handle Bathroom Faucet Installation

Installing a single handle bathroom faucet on either the tub or on the sink is a great way to upgrade your bathroom.  However, as simple as a single handle bathroom faucet may seem, it can be tricky to install. These basic guidelines can help make installation easier.

Step 1: Removing the Old Faucet from the Sink

Before removing any faucet, be sure to turn off the water valves at the supply tubes. You can remove the supply tubes with a basin wrench and drain the water into a bucket. Remove the locknuts and washers on both tailpieces and pull the faucet out from the top.

Step 2: Preparing for Installation

If you already have the sink in place, you may only be able to access the faucet from underneath. This can make the task awkward, but can be assisted with a basin wrench.

Make sure your sink has the appropriate number of holes for the unit. With a single handle faucet you will only need one. Most faucets will require some assembly; if this is the case, follow the manufacturer's instructions.

Use flexible supply tubes to make connecting your new faucet easier.

Step 3: Installing the New Faucet

You will want to be sure you have a clean surface where the new faucet will sit. Insert the rubber gasket between the base plate and the sink to create a watertight seal. If you did not receive a gasket, then seal the faucet base with plumbers putty and insert the tailpieces through the holes.

Step 4: Positioning the New Faucet     

If the water supply tubes are attached to the tailpieces, feed them through the middle sinkhole and put the faucet into position. Thread a washer and mounting nut from underneath onto each tailpiece and tighten the nuts with a wrench.

Step 5: Installing the Drain

All faucets come with a pop-up mechanism allowing you to open and close the drain by pulling a lift-rod behind the spout. Remove the stopper from the tailpiece and install the tailpiece so that the pop-up port is facing the spout.

Insert the lift rod into the hole that is on the back of the spout and attach it to the pivot rod with the extension rod. Adjust these so that the drain stopper opens and closes properly when operating the lift rod.

    Step 6: Connecting the water

    Next, you’ll want to connect the hot and cold supply tubes to the faucet. This may require bending them gently to meet the shutoff valves. Tighten the flared fittings or compression nuts, and turn on the water to clear any debris and to check for leaks that may have sprung up during installation.
