Here's our plumbing tip for May 2015.
Unclog you p-trap yourself. All sinks have a p-trap. That is, it's literally shaped like a P, and it traps sewer gas. Water remains in the U shape, creating a "water-tight" block that the sewer gas cannot penetrate. So, the sewer gas is "trapped" in the pipe. It's also where hair freqeuntly gathers, and clogs the drain. Clearing the p-trap is simple:
1. With a channel locking wrench and a a bucket in hand, locate the p-trap
2. Place the bucket under the trap to collect the standing water in the trap
3. Use the channel locks (pliers) to loosen and remove the trap "U" joint
4. Remove debri
5. Put back together
