For tough clogs, use a full cup. While that sits, bring a half pot of water (about 4 cups) to boil. Pour this directly into the drain very slowly but steadily to avoid getting burned by splashing water. Allow to sit for 10 to 15 minutes, then run water down the drain to check how freely water flows.
Pouring boiling water down the drain to unclog it most likely won't work. Sure, there's a very small chance it could loosen the clog, but there's a larger risk of softening or melting PVC joints.
Pouring boiling water is quite risky as it might lead to a steam burn or scalding. Another thing to keep in mind is what type of material you are pouring in into. If you have a porcelain sink, it is likely to crack due to the heat. All in all, pouring boiling water down your drain will only cause issues down the road.
Let it sit for 5 minutes. Boil up a water kettle (or 10 cups of water) and carefully flush the drain. Many clogs, especially kitchen drains, develop due to fats and oils that get cold and harden inside the pipes. Simply using a large amount of boiling water will clear the clog.
Weekly Drain Maintenance
Weekly, there are a few things you can do to give your drain the best chances for not being clogged. Once a week, flush your drain by boiling a large pot of water. Pour one-half of the pot down the drain. Wait five minutes and pour the rest.
Hot water will break down the grease better and when aided by a cleaning agent, grease is a goner. While cold-water jetting can bust through a blockage, you will not truly clean a pipe and rid it of the FOG buildup unless you clean it with hot water.
For clogged or slow-running drains, apply the product and let it work 15 minutes, then flush with hot water. For tough problems, allow 30 minutes before flushing.
Baking Soda and Vinegar
We suggest that you mix 1/3 of a cup of baking soda with 1/3rd of a cup of vinegar to create your drain unblocking remedy. When mixing the two ingredients, they should start to fizz straight away so you should waste no time pouring the concoction straight down your sink.
Bring water to a boil and then pour it down the slow clearing drain (recommended to use a whole kettle) Put half a cup of baking soda into that drain and let it sit for a few minutes. Add 1 cup of vinegar for every 1 cup of hot water you pour down the drain. Cover the drain with a plug and let it sit for 10 minutes.
When you are using a baking soda and vinegar solution to clean out your drain, you are actually causing the rubber and plastic that are used for the drain's pipes to be eaten away by the mixture. Over time, this rubber and plastic will break down, causing the drain to become even more blocked.
While hot water can help loosen up debris, coarse salt actually scours the inside of your pipes, removing more material than hot water alone. After removing standing water from the sink, pour about half a cup of table salt down the drain before you pour in the hot water.
Baking soda, vinegar and boiling water can help clean drains naturally, but you may need something stronger, like Liquid-Plumr, to fully unclog those really tough drain clogs.
Using a snake is also more invasive and time-consuming than using a chemical cleaner is, and can often become a dirty job. When it comes to getting at and removing major clogs or clogs that are deep down in your pipes, however, a plumber's snake is your best bet.
Pour Hot Water into the Toilet
If you need to heat some in the microwave or the stovetop, you don't want it to reach boiling temperatures. Boiling water can cause toilet porcelain to crack. Allow the hot fluid to sit in the toilet for a few minutes to loosen the clog.
Hydrochloric acid, also known as muriatic acid, is a strong acid that is commonly used to dissolve clogs in drains. This acid works by breaking down organic materials such as hair, grease, and soap scum that can accumulate in pipes and cause blockages.
Corrosion
The chemicals in the product are designed to break own the clog, but if left for too long, they can start to break down the pipes themselves. This can lead to cracks and leaks in the pipes, leading to various issues, including water damage and flooding.
Drano® Liquid Drain Cleaner starts working to unclog your drain on contact. After 15 to 30 minutes, clogs are substantially minimized or dissolved. A final blast of hot water flushes away what's left of the clog.
As for a clogged drain, this may or may not be a plumbing emergency. When conditions of the blockage are severe — such as when water stops flowing completely and can disrupt daily operations — it can qualify as a plumbing emergency.
You may be surprised to learn that pouring soda down the drain does work for some clogs. To be specific, you need a dark-colored cola (such as Coca-Cola or Pepsi). This type of carbonated beverage usually contains a good amount of phosphoric acid, which given enough time, can eat away at some types of clogs.
Just like cooking oil, bleach is one of those things you shouldn't pour into your sink. You should also never use bleach to unclog your drains. Doing so can even burst your drain pipes, and you'll be left with a nasty and expensive mess. Last but not least, it's harmful to the environment and sea life.
It is safe to leave baking soda (and vinegar) to work overnight to unclog a drain. Always flush this mixture down with boiling water—no matter how long you leave it sitting in the drain.
