What's That Sink Smell?

Something wicked is brewing from the sink. And you have no idea what on earth could be causing that cursed scent. Dauenhauer is here to save the day. We have a few thoughts on what could be rotten in Denmark.

Sewer Smells

Sometimes sewer gas can rise up through the drains if there are empty drain traps. This happens more commonly in drains that are not used very often. Just to be safe, you should also check that you don’t have a natural gas leak.

Pipe Blockage

Drain pipes and sewer vent pipes can become clogged. Check to see if, when running water, it eventually stops draining and starts to pool in the sink. If there is an odor that comes up with it, you likely have a sewer pipe blockage.

Water Issues

Sulfates in the water can cause water to smell. A lot of times this happens with hot water heaters when sulfate-reducing bacteria enter the system and react with the sulfates in the water heater. That rotten egg smell? That’s what this is.

Mold or Mildew

Mold and mildew can build up if there is even the smallest leak in a pipe underneath a sink or even behind a wall. Unfortunately, these are pretty common.

Plumbing Error

As we all know, mistakes can happen. This can be said in life, and plumbing. Sometimes missing traps or vents can cause a smell. Leaks and rotting drain tubes are things that can cause odors in the drain as well.
