If you’ve noticed that your kitchen drain smells like rotten eggs, a clogged sewer line repair might provide answers to what’s causing it. However, it’s best to understand what this smell is all about and what’s causing it even before you call the plumber. Oak Plumbing explains further in this post.
Why Does Your Sink Drain Smell?
The odor of sulfur–aka the smell of rotten eggs–is produced by hydrogen sulfide gas or “sewer gas”. In crude petroleum, hydrogen sulfide gas can occur naturally. Hot springs, volcanic gases and natural gas can also produce it. However, what you’re smelling from your sink drain is likely caused by the breakdown of organic matter that produces bacteria. Human and animal wastes are the usual culprits.
A light odor is unpleasant but usually harmless. It is possible, though, for the smell to be so strong that your nose becomes immune to it. In high concentrations, hydrogen sulfide gas can be a health risk, and may even be life-threatening. Breathing it in is often the main form of exposure, but it can also harm your eyes and penetrate your skin.
How Can You Deal With the Odor?
Your water heater may be affected, and if the damage is bad, you might have to ask about water heater replacement costs, but it’s also possible for the pressure tank to be exposed. Sometimes, if the problem isn’t serious, simply running the water for a short time can make the odor dissipate and you can safely use the water.
You can also disinfect the drain by pouring half a cup of bleach down it and pouring water in after it until it overflows. However, a vent blockage can also cause the problem. It may force the gas to escape the P-trap. Vent icing is also possible. Check for this if the odor only occurs in winter.
To make sure the odor is taken care of safely and properly, call a professional. Oak Plumbing can help you, whether you need to find out about water heater repair costs or the cost of maintaining your plumbing system to prevent that rotten egg smell.
