Seattle Drain Cleaning Tips
WHAT’S THAT SMELL?
Has a bad odor suddenly surfaced in the house? There’s no sign of any kind of sewer back up or clogged drains. It could be there’s a sink or shower that hasn’t been used in a long time and the water in the “P” trap has dried up, allowing sewer line gases to come up through the drain.
The “P” trap is the u-shaped tube in the drain line. That trap holds water and the water acts as a barrier to the gases/odors from the sewer line. Also, sometimes a rodent or other pest dies underneath the crawl space and can lead people to think there’s a problem with their sewer line.
