Faucets have gotten more complex. In the past, replacing the packeting nut and packing washer stopped dripping. Modern faucets now use valvet or cartridge values. For newer faucet models, more than a screwdriver is needed for replacement. Call 303-781-7856 or email us at info@billsmith-plumbing.com for an appointment to service your faucets. We look forward to earning your business.
