Victorian Be careful when purchasing faucets. In most washer less faucets, the control of the water flow is done by a cartridge or arrangement of seals that allow water to flow when the holes or ports are lined up. The design is such that the water flow is basically sheared off. Unlike 'washer' types, extra strength of pressure on the handle will not help stop the water flow. There are many different designs of washer less cartridges.
Some foreign cartridges can be very expensive.
Ceramic cartridges are becoming very popular. Ceramic cartridges have been around for over 20 years. Ceramics tend to last longer than other types of cartridges but can cost a lot more when replacing. Remember, all faucets will eventually leak. It is true that you don't always get your money's worth by paying more.
