Installing A Kitchen Sink Sprayer

By

Kitchen sink sprayers have been around for a long time and they continue to be popular because they are so useful. Before there were all of these new faucets with built in sprayers there were sprayers separate from the spout found either in the body of the faucet plate or on the side by itself in a separate hole. Free standing kitchen sink sprayers are still available so don’t think that you need to buy a new kitchen faucet to install or replace a kitchen sink sprayer. Installing a kitchen sink sprayer is a fairly easy project that you can do yourself if you do not mind laying under the kitchen sink for a bit while remove and connecting everything back up.
  1. Check that your sink and faucet can accommodate a sprayer. Check the configuration of the sink to make sure that there is an available mounting hole for the sprayer. Also, check the faucet to make sure that there is a diverter for the sprayer. If the faucet doesn’t have a diverter a sprayer cannot be installed.

  2. Buy the right sprayer for your faucet. When replacing an old sprayer it is always a good idea to remove the old sprayer from the faucet before you begin. Most sprayers are universal but it never hurts to double check because there are a few that have different connections.

    To remove an existing sprayer:

    a. Shut off the water to the faucet.

    b. Remove the sprayer flex line from the faucet body. There should be a copper tube or brass bolt coming down that will have a brass connector on it where the hose is screwed onto. Hold against the brass connection and the hose nut that you are removing. If you do not hold against this and it is the copper tubing it can twist the tubing going into the faucet and break the faucet.

    c. With the hose disconnected from the faucet pull the sprayer up and out from above the sink. Take this piece with you to the home improvement or hardware store to purchase the replacement sprayer.

  3. Install or replace the housing for the kitchen sink sprayer.

    a. Remove the sprayer housing (if necessary) by unscrewing the mounting nut from under the sink with a pliers or basin wrench. The body may turn with the nut so in this case you will have to hold against it.

    b. Install the new sprayer housing by putting it through the top of the sink into an available hole. The housing should have some gasket around the base of it. If it does not can put plumber’s putty under the base to help seal it and keep water from getting under it.

    c. Tighten the mounting nut for the sprayer housing from under the sink. Hold against the housing if tightening the nut turns the whole thing.

  4. Connect the kitchen sink sprayer to the faucet. Push the new sprayer hose down through the housing so it is all the way in and ready for the connection. Before you connect the hose onto the faucet make sure it is in a position that will allow you to pull it out easily without getting tangled up with everything else that is under the faucet. Be sure to hold against the body of the faucet when tightening the sprayer hose nut to make sure it does not twist and damage the faucet.

  5. With everything tight turn the water back on and check the sprayer for leaks. Run hot water through the sprayer to loosen the tubing and allow it to go up and down easier.
