I recently have my bathroom remodeled with earthen tile. Now my bathtub faucet have a steady drip. Is there an uncomplicated way I can fix the drip from the button. It's a one handle lever system by Delta.
Answers:    Yes, your local Home depot, Lowe's, Menard's, Hardware store,etc. carry Delta faucet re-build kits (seats and springs) Easy to do, newly follow the instructions in the carton.
You can fix it by replacing the rubber washer in the knob. You can buy a packet of assorted washers at any hardware store for about a buck
