Faucet manufacturers make several types of replacement kits for ball-type faucets; some kits have only the springs and neoprene valve seats, while better kits also have the cam and cam washer.
Once you have the faucet out, replace all rubber washers and o-rings. When replacing washers, check the condition of the metal valve seats inside the faucet body. If the valve seats feel rough, they should be replaced or resurfaced.
In fact, you will be surprised to find how low the price is for which you can get a beautiful kitchen faucet with a lot of helpful features. The word of wisdom says, "He pays a lot who buys cheap", and to a certain degree that still applies. If you consider purchasing a faucet below $ 80, you might want to find an answer to a question, what makes it that cheap.
For pull-down models, the hose needs to be guided through the faucet body and spout, for touch sensitive models, there will be a battery pack that needs to be connected to the contacts.
