This bathroom sink clogs periodically, then will be fine for a while.
When it does clog, however, 'black stuff' comes out of the drain when you plunge it?
girls put seriously of things down the drain...hair...soaps...spawn up.creams and more.that might be the black stuff u see that builds up over time.best thing is to remove the trap underneath the sink.when its removed look down the drain and if the walls of the tail pipe ( which is the pipe attached to the sink about 6 inches long ) is clogged surrounded by any way later use so sort of stick or butter knife and try to push the muck through ( enjoy a bucket ready to detain anything that might fall through.be sure to also verbs out the drain that u removed.feel up inside the other expiration of the pipe where the trap be screwed to.hair may be up inside


Try this:
In the evening when you definitely will not run any hose in the bathroom sink for the rest of the evening--take a bottle of Liquid plumber and pour the entire bottle down the sink,,,,,follow this near 8 ounces of water. And vacate it there adjectives night.
Your drain problem is not underneath the sink contained by the ''trap'',,,it is further on in the drain. This give it a chance to start breaking it up.
Answers:    time to replace your gamble away pipe, you may get away near cleaning/renewing the trap beneath the sink waste, but I see this adjectives the time with pipes that are at lowest possible 10 years old, check the complete length of the waste pipe run too, if it go uphill at any stage this will slow the flow and allow easier clogging.
