BLEACH DOESN'T CLEAR DRAIN CLOGS.
It cannot dissolve things like food waste, breadcrumbs, grease, and hair. Instead, pouring bleach into a clogged drain will make things worse. The bleach could react with other chemicals, creating dangerous fumes, and if the reaction is violent, it can even burst your drain pipes.
Using Bleach
Once a month, pour 12 ounces of chlorine bleach straight down the drain at the end of the day. Be careful not to let the bleach sit in the bowl of the sink, especially if the sink is stainless steel. In the morning, flush the pipe thoroughly with water from the faucet.
Pour Some Bleach in It: Bleach, like other disinfectants, kills almost every species of odor-causing bacteria commonly found in drains and sewer lines. So, an easy DIY step you can take to reduce drain odor is to use bleach.
Pour baking soda and vinegar down the drain: Run hot tap water for several seconds, and then turn the water off. Dump one cup of baking soda down the drain followed by two cups of hot vinegar. Let the concoction fizz. After one hour, flush the drain with hot tap water.
You can put small amounts of bleach down PVC pipes, but it probably won't break up clogs very well. Larger amounts can be dangerous. The bleach can also combine with substances trapped in the pipes and cause a reaction.
If you are noticing the smell of rotten eggs, it is possible that your water or sink drain is contaminated. It could also be that the drain is clogged or partially drained. When sinks are clogged, they drain slowly, which can cause bacteria to build up in the p-trap and create the hydrogen sulfide gas.
Household Chemicals
You may permanently damage your septic system. Bleach and cleaning fluids create toxic gasses when mixed together. If you pour bleach and other cleaning agents down your sink drains, and they mix in your pipes, you can contaminate the air in your home with the resulting gas created.
Smells in a shower drain can be caused by odor-causing bacteria that feed on debris in the pipe. Some of these anaerobic bacteria live in fetid water in the P-trap and produce hydrogen sulfide gas, which smells like sewage. Other odors can also be caused by the debris itself, like hair or soap scum build-up.
Unclog Slow Drains
Pour 1/2 cup baking soda, followed by 1/2 cup vinegar down drain. Plug drain, and let sit for one hour. Then, pour a pot of boiling water down drain. Repeat if necessary.
Mix 1/2 cup baking soda with 1/4 cup table salt and pour down the drain giving you trouble. Follow by pouring 1 cup of heated vinegar down the drain (it will foam and bubble). Cover the drain with a plug or duct tape to prevent the mixture from escaping. Let it sit for 15 minutes.
There could be odor-causing bacteria feeding on debris in your pipes. This process will give off a foul-smelling hydrogen sulfide gas, which smells like sewage or rotten eggs. Also, mold grows where it's warm and wet — and mold growth on the debris causing a drain clog can also cause a bad smell.
Disposing of your bleach can be done easily in a few simple steps. Bleach can be poured down the kitchen sink or toilet, just as long as it's diluted with water. An even better way to get rid of your bleach is to give it away to someone else who needs it, such as a friend, family member, or local community center.
The other option is to try and use ammonia. Ammonia is one of the best products for loosening sink clogs before plunging the sink to force the clogs through the drain.
Chlorine, especially in the diluted ppm's we work with can not damage PVC.
Use Baking Soda & Vinegar Before Plunging It Out: Baking soda and vinegar can be an extremely effective way of dispatching many clogs, and hair clogs are no exception. For best results, start by squirting a little dish soap into your drain, followed by a cup of vinegar and a cup of baking soda.
Why Does My Sink Smell? A smelly sink is usually caused by bacteria build up from grease, fat and food which have been flushed down the drain. These will then get stuck in the pipes causing the familiar rotten egg smell.
If the smell comes from the drain, it could be a result of sediment buildup from daily bathing. These sediments include dead skin cells, soap, shower gel, and hair. This accumulated sediment is called biofilm. Over time, it clogs the drain, leading to bad odors.
Broken, Clogged or Poorly Installed Vent Pipes
The vent pipe is your sewerage system's breather. When it gets clogged, the sewer gases can back up into the sinks and the toilet, resulting in your bathroom's sewage smells.
Do NOT pour boiling water down your sink or toilet.
This can melt PVC piping and pipe seals, causing serious damage. In addition, using boiling water to clear a clogged toilet can melt the wax ring around the toilet, or even crack the porcelain bowl, leading to a pricey trip to your favorite hardware store.
Bleach is a powerful, toxic substance that should be used carefully and properly, and pouring it down a drain is not a proper use. Bleach can react with other substances in your pipes, potentially release fumes, and further plug up the system.
Liquid, gel and powder water-soluble household cleaning products can be flushed down the drain. Solid products include soap pads, sticks, towelettes.
First off, if your drain smells musty, you most likely have active mold growing underneath the drain cover. But if your drain smells like rotten eggs or sewage, you're either smelling: “Biofilm” from a clogged or dirty drain or. Sewer gases that have escaped your drainage pipes.
Smelling sewer in the home means there is an issue in the shower with the drain, a vent pipe that is cut or not installed properly on the toilet, or seals that are broken or loose. Finally, a build-up in the overflow of the sink can also cause this smell.
