How To Install a Bar Sink Faucet

Installing any sink faucet is a basic plumbing task. All sink faucets require the same basic installation – secure in place and attach water supplies. A bar faucet has a style different than other sink faucets. A bar faucet usually has a smaller base assembly with a taller neck. It is assumed that we will need it to supply water for more than just hand washing or filling a large bucket like a bathroom sink or a laundry tub.

  1. Faucets of any type are either attached through holes in the counter or holes in the sink. Unlike bathroom vanity faucets, a bar faucet does not require a drain pull. They only need a supply of hot and cold water. All faucets require water supply lines.
  2. These supply lines can either be flexible braided hoses, narrow plastic formed pipe, or even flexible copper pipe. Toilet supply lines are very similar and also come in the same styles as faucet supply lines so read the label to be sure you’ve sourced the right one. It is also important to measure the distance from the water supply valve to the bottom of the threaded faucet end so you can match the length of supply line.
  3. Flexible braided lines are flexible enough to even bend around in a circle if they have to. Plastic formed supply lines are by far the least expensive and perhaps the easiest to use because they can be cut to length right under the sink. First insert the bar faucet through the holes. From the underside of the sink, attach the retaining nuts to the threaded portion on each side.
  4. This can usually be done by hand. Align the bar faucet until it is centered on the sink and evenly spaced from side to side. Tighten these retainers so the faucet is securely in place. With braided lines that are the correct length,you need only attach the nut securely to the valve and the faucet.
  5. If copper or plastic lines are used, you will have to attach the line by way of a compression nut. Put the compression nut on first, then slide the compression ring up to the approximate length required.  After cutting the line to the proper length, insert it into the valve.  It will only go about a quarter of an inch into the valve. Slide the compression ring down and seat it at the valve.
  6. Next bring the nut down and thread it onto the valve. After each end is secure, open the supply valve and it should be ready to test. If small leaks are found, check the connections to ensure they are tight. These supply lines generally do not require any sealing tape or putty on the threaded connections. The lines will seat them selves if aligned properly.
