The Kitchen Sink Faucet Is Not Working But the Sprayer Hose Is


When a sprayer hose attached to a kitchen sink faucet does not operate but the faucet itself does, the issue is most likely contained inside the fixture that houses the faucet. The fact that the sprayer hose is operational rules out the likelihood that the problem lies with your water pipes and narrows the scope of the issue to either a clog in the faucet, a malfunctioning aerator, or an issue with the spray diverter.

Faucet Screen

The screen for the faucet is located at the end of the faucet spigot, which is the point at which water would normally come from the fixture if there were no issue. The end of the faucet has a screw that can be unscrewed, but the faucet itself is often only hand-tight. If the end of your faucet is difficult to remove, you may protect the surface from scuffing by using pliers that have been wrapped in a towel. Take off the end of the faucet, and then take out the screen from the faucet. To determine whether you have succeeded in locating the cause of the problem, try turning on the faucet while removing the screen. If the faucet is still functional, immerse the screen in vinegar to remove any mineral deposits that have collected and then replace it.

Sink Aerator

You should be able to find the aerator in the same area of the faucet as the screen. Aerators are susceptible to being obstructed by debris as well as mineral deposits. In order to replace an aerator, you will need to identify the brand and model number of your faucet and then get in touch with a business that sells plumbing supplies. It is possible that you may need to make an order for the component, but if your sink is already rather old, you could find it more convenient to just replace the complete fixture.

Spray Diverter

When the sprayer’s handle is depressed, water is sent to the sink sprayer via a spray diverter. This little cartridge is a pressure switch, and as long as the sprayer is not being used, the switch will stay closed and water will continue to flow from the faucet. When the handle of the sprayer is pressed, a diverter flips and shuts off the faucet, which then allows the sprayer to be turned on. Your faucet’s diverter is located inside of it and may either be repaired or replaced. Stop the flow of water to your faucet by turning off the valves that are located beneath your sink. Loosen the cap that is located behind your faucet, directly in front of where the faucet actually connects to the sink. The diverter may be loosened using pliers once the faucet neck has been removed from the faucet assembly. The diverter is normally put in a horizontal position on the rear of single-handle faucets, while in two-handle sinks, it is installed in a vertical position in the centre of the assembly. After replacing the diverter with a new component that is designed to work with your specific model, reassemble your faucet.

Faucet Clogs

Mineral deposits may build up over time and cause the faucet’s aerator and screen, as well as the faucet itself, to get blocked. Because the mineral deposits can only be removed by soaking the faucet overnight, it is not possible to clean your faucet while it is still installed because of this. You need to disconnect the water lines from the faucet and turn off the water supply that is located beneath the sink. After removing the bolts that are securing the faucet to the sink, raise the whole assembly off of the surface of the sink. To remove any mineral deposits that have collected on the faucet, soak it overnight in a solution consisting of warm water and vinegar. Simply reverse the steps used to remove the faucet in order to reinstall it.
