III. 5 Hidden Culprits for a Smelly Shower Drain
1. Biofilm Buildup (The Slimy Culprit)
Have you ever found yourself dealing with a slimy, slippery surface at the interior part of the drain? That’s biofilm, a combination of bacteria, soap scum, and oil from your body, don’t worry it’s a part of the common skin condition. Eventually, this substance attaches itself to the walls of the drain where it forms a base upon which bacteria that cause odor grow.
How to Fix It?
- To do that you simply pour hot water down the drain so that the gunk will loosen.
- Pour this concoction that is baking soda and vinegar, and allow it to froth for at least 10 minutes.
- Scrub the drain cover and inside walls with an old toothbrush or pipe cleaner.
Did You Know? Scholars are aware of the fact that bacteria found in biofilms are about 500 times more resistant to chemical solutions compared to planktonic bacteria. That’s why scrubbing is essential!
2. A Dry P-Trap (The Evaporating Problem)
The P-trap also known as the U-trap is mainly located under the shower and consists of a curved pipe. It does contain a small quantity which works as a floating seal to prevent the sewer gas from coming out. If a shower is left unused for some time, the water in it dried up paving way for unpleasant odors to set in.
How to Fix It?
- If the trap has become empty, then let water flow through the shower for 30 seconds to fill the trap.
- Boil approximately half a cup of water with one teaspoon of vegetable oil and pour the mixture into the drain in order to minimize the rate of evaporation.
Special Note: If your guest bathroom has an unpleasant smell especially in the shower then there is a possibility that the problem lies in the P-trap which is present in showers that are seldom used.
3. Blocked Vent Pipes (The Silent Stink Maker)
These small pipes are used in the house to ensure that air circulates within the pipes so that water does not accumulate any pressure and all the wastewater too can flow freely. This is especially so if a vent pipe is obstructed (by junk, birds nest or ice); this leads to slow flow of the sewer system as well as the gases finding their way back into the system.
How to Fix It?
- Sometimes when the shower is being used, gurgling noises coming from the ‘throats’ should alert one of a blocked vent.
- Through the inspection of the roof vent, clear any accumulation of debris or nests of birds among other hindering factors.
- If one is still skeptical, it’s advisable to call a plumber to check on any blind pipes and sort them out.
Did You Know? This article argues that obstruction of vents can cause significant slowed down of water flow to the extent of 50% thus slowing the entire drainage system.
4. Leaky Pipes (The Hidden Offender)
A damaged drain pipe can often let out wastewater into the below flooring, which is why you get a stench related to a damp environment. In the process, it may cause mold formation and deterioration of other structures within the house.
How to Fix It?
- Look for signs of damp under the shower or nearby walls in the form of discolouring.
- Take a whiff—the presence of offensive odors such as mildew or sewage in the area near the shower is not good.
- If you are experiencing such a problem, better call a plumber to check the situation and fix it.
As already mentioned, water leakage can lead to mold formation within 24-48 hours so it requires immediate attention.
5. Hair and Soap Scum Buildup (The Sticky Problem)
Soap scum, hair and residues from shampoo clog your pipes so well allowing water to stick to it instead of flowing. This builds up, seals the drain, creates a buildup of bacteria and results in a bad smell like that of a decaying substance.
How to Fix It?
- The other method of floor drain cleaning involves using the drain snake or the plunger to clear the hair trap.
- It is advisable to pour a cup of baking soda then follow it with vinegar to help dissolve buildup.
- A hair trap should be installed to prevent any hair from flowing with the water into the pipe.
Proven Feature: The hair build up contributes to about 80% of the shower drain clogs. As much as this may sound like an inconvenience, you do not have to deal with this issue if you only clean your drain regularly.
IV. How to Remove Bad Smell from a Bathroom Drain?
