To disassemble unscrew the bonnet from the faucet, using slip-joint pliers. Remove the valve stem, keeping in mind this has reverse threads, so unscrew it by turning it clockwise. Older compression faucets may have corroded handles that can be difficult to remove. Most hardware stores and rental centers have a specialty tool called a Handle Puller which makes the job easier.
For modern faucets, the truth is quite opposite though. The touch function is reliable and under normal conditions always works as expected. These faucets cannot be activated by pets, and they are helpful for families with children.
To disassemble unscrew the setscrew and pull off handle. Though these faucets are washerless, they do have inlet and outlet seals that may leak, or sediment may build up inside the inlets and cause leaks. After removing the escutcheon cap, lift out the cylinder and clean the neoprene seals and cylinder openings. Be sure the faucet is in the "open" position when replacing seals.
The decision may be tough at times. But it does not have to be like buying a pig in a poke. With a little research, you can find a lot of useful feedback from existing users about how the touch sensitivity works in different kitchen faucets. Some faucets have tens, if not hundreds, of reviews on the largest online vendor websites like Amazon. The number of reviews and the ratings given can be a good indication of the quality of the faucet. You can see if there are a lot of people having issues with the touch sensitivity in a particular faucet.
