Installing An AquaSource Faucet

An AquaSource faucet is an economical option for replacing an old or faulty bathroom faucet. There is a wide range of AquaSource faucets to choose from. Generally the installation instructions are basically the same although there may be slightly different instructions for each AquaSource faucet model. The following instructions are for a two handle WaterSense bathroom faucet, but they can be used for most AquaSource bathroom faucets and other top mounted bathroom faucets.
  1. The first thing to do is to shut off the water supply to the old faucet. Then remove the faucet that is currently installed in the sink. This is a good time to clean the sink and remove any old putty or hard water buildup. If you will be replacing the pop-up drain as well this is when the drain trap and old pop-up should be removed so they are out of the way.

  2. Next install the faucet body. From the top of the sink put the faucet into place over the three faucet openings. To fasten the faucet into place reach under the sink and install the lock nuts onto the two threaded tailpieces. Before completely tightening the lock nuts check that the faucet is centered and straight.

  3. Connect the water supply lines to the faucet. It is always better to change the water supply flex lines when installing a new faucet unless the existing ones are fairly new.

    Attach the hot and cold water supply lines to the corresponding threaded tailpiece of the faucet.To tighten the water lines it is a good idea to use two pliers so you can hold against the stop valve or the faucet while tightening the flex line. Be careful to not over-tighten when using pliers.

  4. To install the drain assembly first separate the pop-up drain components. Slip the rubber washer onto the pop-up body and drop the pop-up into the sink drain opening. Position the opening for the ball rod so that it faces back. From under the sink slip the washer and nut onto the pop-up drain body and tighten. As you tighten check that the pop-up is centered properly in the sink opening.

  5. The next step is to install the pop-up drain stopper. Insert the stopper into the drain. Under the sink insert the ball rod into the pop-up drain opening and tighten the sleeve to keep it in place.

  6. To install the pop-up lift rod start by inserting it into the faucet opening. Under the sink attach the perforated strap to the lift rod. The button on the strap can be pushed in to open and locks into place when released. Attach the ball rod to the lift rod after adjusting the height of the stopper.

  7. With the AquaSource faucet installation complete you can put the drain trap back into place and turn the water supply back on. Checking for leaks is the final step of any faucet installation.

    First turn on both the hot and cold sides of the faucet and check for leaks under the sink. Allow the water to run for a couple of minutes as some faucet leaks are not obvious right away. Use a flashlight to look around under the sink so you don’t miss small leaks.

    To check for leaks at the pop-up drain lower the stopper and fill the sink up with water. Release the water and look under the sink for leaks around the drain.
