A blocked or clogged drain is a pain, but it doesn’t mean that you need to call a plumber. Most clogged drains can be easily cleared by using things that are around the house or just a few inexpensive tools.
Unclogging Bathtub Drains
All drains have a similar construction. At the bottom of the drainpipe is a curved section of pipe called a trap. Under sinks this trap is shaped like an “U”, while most bathtubs have a slightly different shaped trap called a “P” trap, since it’s shaped like the letter “P”. The curves in the trap are there to “trap” some water in the drain line, and prevent sewer gases from coming up the pipe and smelling up the house. Over time, however, the traps will sometimes get blocked with things like cooking grease or food particles (in kitchen drains) or hair and soap scum (in bathroom sinks). Slow running drains are partially blocked, and drains that don’t drain at all are obviously totally blocked.
