This tip will show you how to fix a slow tub drain. In my experience
most slow shower and tub drains are caused by hair. Usually within reach of a wire hanger. Since you probably do not have all the proper tools, you must be careful not to damage your drain line.
The trickiest part with most shower drains, is the pop up assembly.Most times the hair is caught on the pop-up components. If you have a pop-up, check with your local hardware guy to show you how it works and is assembled. On a pop-up, you'll have to take the drain plug/cap off. have the cap in up position, and get your eyes below the cap rim, you will see a small set screw, a couple turns and cap should come off, do not take set screw all the way out.
If you see hair on assembly after taking assembly out, remove the hair and run some water to see how your drain is working. If that does not fix your slow drain, you should stop there and call a plumber, because that means you blockage is further down the line then you'll be able to reach.
If you have no pop-up assembly. Untwist hanger, make as straight as possible, then with a pair of needle nose or any pliers you have, go about a half inch in from the hook side. Make a U bend, about the same size and shape of the end of a paper clip. Go in drain a inch
and turn hanger in a circle trying
to catch the hair blockage. Twist a couple times and pull back gently,
do not push hanger in to far, you might break your pipe or the hanger may get caught in the p-trap or even worse drum-trap,(older houses tend to have drum-traps, I suggest not to even attempt to clear any blockage were a drum-trap is involved,call a plumber)
If its hair, you will see this black sludge looking hair ball that may make you sick. Don't worry you'll be happy when all is said and done, and you can shower without standing in your own filth. If its not hair, you probably
have a more serious problem. Call a plumber and make sure your plumber gives free estimates.
