If you turn on the kitchen faucet, and no water comes out, but the sprayer works, there are several possible reasons for this issue. Here are some common causes:
- Clogged Aerator: The most likely reason is a clogged aerator. The aerator is a small mesh screen located at the end of the faucet spout. It can accumulate mineral deposits, sediment, or debris over time, obstructing the flow of water. The sprayer, which is usually separate from the faucet, may not be affected by the clog, allowing water to flow through it.
Solution: To fix this, unscrew the aerator from the faucet spout and clean it thoroughly. Soaking it in vinegar or using a brush to remove the deposits should help restore water flow.
- Valve Issues: There might be an issue with the faucet's valve or cartridge. These components control the flow of water. If the valve is stuck or damaged, it can prevent water from coming out of the main faucet while still allowing water to flow through the sprayer.
Solution: You may need to disassemble the faucet and inspect the valve or cartridge for any problems. Replacing a faulty valve or cartridge might be necessary to resolve the issue.
- Supply Line Problems: There could be a problem with the water supply lines leading to the faucet. If there is a blockage or a closed valve in the supply lines, it can affect the water flow to the faucet but not to the sprayer.
Solution: Check the supply lines under the sink to ensure they are not kinked or blocked. Also, verify that the water supply valves are fully open.
- Faulty Diverter: Some faucets have a diverter that directs water to the sprayer when you press the sprayer button. If the diverter is malfunctioning, it may not allow water to flow through the main faucet while still working for the sprayer.
Solution: Inspect the diverter for any issues. In some cases, you might need to replace it.
- Pipe Blockage: A blockage in the faucet's water pipe can restrict water flow. This blockage may be localized to the faucet, causing the issue you are experiencing.
Solution: If the previous solutions don't resolve the problem, there could be a blockage further up the water supply line. In such cases, it's best to call a plumber to investigate and address the issue.
Before attempting any repairs, it's essential to turn off the water supply to the faucet. If you're unsure how to diagnose or fix the problem, consider consulting a professional plumber to avoid causing further damage.
