浴缸的排水管上面有个盖，拿不下来，只有大概一公分的空间。怎样才能清除里面的污垢？另外如何预防呢？
最近发现水排得慢了，但也没有完全堵上。我知道可以用Draino清除排水管，但不知道能不能清掉头发等污垢。[/B
The shower drain system has a sloped floor,a drain opening, a trap, and a drain line that connects to a granck drain line or waste and bent stack. SHower drain clogs usually are caused by an accumulation of hair in the drain line. Remove the strainer cover with a screwdriver, and look for clogs in the drain opening with a flashlight. Use a stiff wire brush or a piece of stiff wire to remove clogs if you can.
If that doesn't do the trick, you may need a plunger. Put the rummber cup over the drain opening and run enough water into the shower stall to cover the lip of the cup. Move the plunger up and down rapidly. If that fails, clear stubborn clogs with a snake.(Closet snakes, Hand snakes, and Coiled Drain snakes.)
