How To Troubleshoot a Kitchen Faucet That Stopped Working

If your kitchen faucet suddenly stopped working, there are a few simple things you can try to troubleshoot the issue. One of the most common causes of a kitchen faucet not working is a clogged aerator. These are located inside the faucet valve, which is often hard to see. The best way to troubleshoot this issue is to change the aerator, which is the most obvious place to start.

Check the supply line

Next, you'll need to check the supply line. This is the thinner line of piping that connects the faucet to the sink. Modern homes have flexible steel or copper lines, while older builds may have flexible all-metal lines. Untangling the line can sometimes solve the problem, but it's best to call a plumber to be sure. If you're unable to fix the faucet yourself, you'll need to replace the supply line.

Call a plumber

Another common cause of a Kitchen Faucet suddenly not working is a clogged pipe. It could be caused by heavy metal deposits, lime, sediment, or both. To troubleshoot the clogged pipe, call a plumber or contact your water supplier. Another problem with a faucet may be rust. Check whether rust is visible outside the faucet to determine if it's internal. If you find any signs of rust, it may indicate a bigger problem.

Kitchen Design

The next most common cause of a kitchen faucet suddenly not working is low water pressure. A water pressure problem in one area of the property could lead to a clogged or blocked aerator. Sometimes, the problem is due to a water supply issue in your area. To identify the problem, make sure you check other faucets in your house. If you find one that's working, the problem might be with a single faucet in your house.

Check the water heater

If the problem isn't a clogged aerator, try replacing the diverter. Most kitchen faucets are simple to replace. First, unscrew the handle of the faucet. Then, use needle-nose pliers to pull out the diverter. You may also want to check the piping to the faucet. If there's no water coming out of the sink, you'll need to check the water heater.

Identify the clog

If the problem is a single fixture, you can try flushing it. This can help remove sediment that has built up. Turning the water supply on and off will also help clear debris. If the problem is a multi-fixture problem, a plumber can perform a video inspection to identify the clog. If it's the cartridge, the issue may be the cause. Once the cartridge is replaced, the kitchen faucet should be working again.

Replace the aerator

If you're not able to remove the aerator, the problem may be with the aerator. If this is the case, you should clean it thoroughly with a toothbrush. Another cause for low water pressure is a blocked water pipe. If you can't remove the aerator, you should backflush it under a sprayer and then replace it. If this doesn't solve the issue, you can also replace the aerator with a new one.
