Most faucets made in the past 20 years or so do not have flexible washers as the water seal when you turn off the faucet. It is metal-to-metal contact, with no washer. So, you shouldn't need to worry about leaking faucets nearly as much. The only rubber components are the o-rings in the faucet cartridge which rarely cause leaks. When it does leak, you just replace the entire cartridge.
