If you live in a newer build home, today's faucets can be a bit more challenging to install or troubleshoot. Although installing a faucet is pretty universal, there are different components that you need to know before going in and tinkering with the pipes. Before going in and trying to fix your faucet, you need to know what the issue is that's keeping your faucet from working right.
Before You Start
Before you start, it's important to shut off the water under the sink. There's nothing worse than trying to operate on your sink and water floods onto your face mid-operation. Also, you should close your sink drain and cover it with a rag so particles don't go down the drain as your working. Tape the jaws of your wrench with a thin layer of duct tape so that you can avoid scratching your surfaces, lay out your parts in order of removal and use distilled white vinegar to remove any mineral deposits that come off the faucet parts.
Low Water Pressure
If you're experiencing low water pressure, it's most likely due to your spray diverter. A spray diverter is a valve that's located inside of the faucet. The main job is to control the water that is going into the faucet. There are two reasons why the diverter is not working: The diverter control is clogged or the diverter must be replaced. If the diverter is clogged with debris and minerals, all you have to do is clean it.
Another culprit for low water pressure could be the aerator. A faucet aerator is found at the tip of an indoor water faucet. They can be simply screwed onto the faucet head so that you will get a mixture of air and water. An aerator can be cleaned with a brush and cleaning solution or vinegar.
Spray Misting from Faucet/Leaks
If the water from your faucet is spraying a mist, check to see if the aerator is screwed on tightly. Use a cloth or a brush to remove minerals, tape or debris because the aerator can be clogged. If the problem still occurs, replace the aerator because it is cracked or damaged.
Faucet Handle Is Difficult to Operate
If a faucet handle is difficult to operate, sediments or debris damaged the cartridge. Debris, metal pieces and minerals can damage the seal within the cartridge, so all you have to do is replace the cartridge or lubricate it with silicone based grease. But don't use silicone sprays or plumber's grade faucet grease that has petroleum. Petroleum-based lubricants may damage the rubber seals on your faucet.
