Compression Style Faucets - this design is used for many double-handle faucets and is the old-fashioned style faucet (when shutting the faucet off, you usually can feel the rubber washer being squeezed inside the faucet.) Compression faucets have separate controls for hot and cold water and can be identified by the threaded stem assemblies inside the faucet body. Compression faucets all have washers or seals which control water flow and need to be replaced regularly over time. The replacement parts are inexpensive and easy to replace.
Some use strong magnets that do a good job to hold the wand in the dock. Others use a smart combination of weights, extremely precise docks and flexible hoses. Whatever the method used in the faucet to keep the spray wand in its place, it might be wise to consult the users′ feedback to see if there are problems with loose fit.
The cleverly engineered touch sensitivity system distinguishes between "touch" and "grip". When you tap it, your hand needs to be removed from the faucet within a fraction of a second. If the hand stays on the faucet, it is identified as a "grip", and the faucet does not respond. So it is practically impossible for pets to activate it.
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.
