My tub faucet is leak, how do I fix it? ...
Answers: Turn off the sea supply, or you'll give the total bathroom a bath.
There's probably a plastic disk covering the top of the manipulate. Carefully pry it off. There's a screw beneath that - remove it. Pull the handle straight stale. If it's been a while since the faucet be installed, that may take a bit of work. (Trick: put a strong towel losing the handle and pull)
Now you'll see a stem sticking up and, at the dais of the stem, a 6-sided nut. Unscrew the nut (an adjustable wrench or pipe wrench - never use pliers on nuts). At the bottom of the piece that comes out, there's a washer - rubber or plastic, usually held in near a screw. (You can buy a little assortment of faucet washers at Ace, True Value, Wal-Mart, etc.) Remove the washer and replace it next to one of the same size and solidity. Screw the stem back contained by and tighten it just a bit - you don't want to break anything. Put the bar back on, replace the screw and replace the cover.
Turn the hose down supply back on. If it still leak (it'll be less of a leak), you'll hold to "ream the seat". You can buy a tool for that for a few dollars at Ace or True Value. They'll explain how to use it.
you will have to metamorphose the washers that are located behind the handle
