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.
Pipe Damage
The hydrochloric acid can break down the coding in your pipes. Over time if you continue to use it, it can cause your pipes to corrode and holes to form. The damage from it can cost more than regular professional drain cleanings or DIY solutions.
Carefully pour ¼ cup (59.15 mL) of acid into the water.
Always add acid to water; never add water to acid. If you get it backward, an explosive exothermic reaction will occur! Pouring undiluted muriatic acid down the drain can ruin your pipes.
Professional Plumbing Tools 101: Drain Augers
Also known as drain snakes, there are several different versions of drain augers that most plumbers will carry with them at all times. In essence, it's a basic tool, but an auger is best for tough drain clogs that just won't budge and for cleaning out drains, too.
Muriatic acid will damage metal pipes over time, but not PVC pipes. Please remember that muriatic acid should be poured into water to avoid the acid splashing up.
Oxidizers, acids, and caustics are examples of drain cleaners that can cause PVC pipes to melt or become soft. Sulfuric acid and hydrochloric acid are the active ingredients of acid cleaners.
A plumbing auger — also known as a plumbing snake — and a sewer rod are effective against some clogs in the main drain line. If you suspect a blockage in the main drain line, don't use the plumbing system in your home until it's cleared. Getting more water into the line could cause wastewater backups in the home.
Like any strong acid, muriatic acid can irritate your skin (prolonged exposure can even cause burns). Gloves will help you avoid direct contact. If you do get muriatic acid on your skin, wash the area with clean water right away (it's a good idea to keep a garden hose or a bucket of clean water nearby).
Muriatic acid may damage concrete surfaces, so be careful when pouring it on sidewalks or driveways; new concrete typically does not need to be cleaned at all before applying staining agents. If you do pour some on these surfaces, rinse off with lots of water as soon as possible.
And never ever mix muriatic acid with other cleaning products. Carefully apply that solution to any mold or hard surface and let it sit for about 10 minutes, then rinse it thoroughly with water.
The Santeen Sulfuric Acid Drain Opener proved to be the most potent among all the chemical drain cleaners we tested, effectively dissolving 80% of the hair, 80% of the organic matter, 40% of the grease, and 76% of the paper products.
Plumbers commonly use hydrochloric acid to unclog pipes
Hydrochloric acid, which is close to muriatic acid, is the most common acid associated with plumbers.
How to Dispose of HCl Safely. Check your local rules first, but here's what I do: Neutralize it with sodium carbonate or soda crystals. Or pour it down the sink with copious amounts of water.
Professional plumbers have access to several tools that can safely clear sewer clogs. Video sewer line inspection cameras help plumbers diagnose the issue, augers (drain snakes), high-power hydro jetters, and professional-strength drain cleaners help plumbers break up or dissolve any clog.
When you can't access a plumbing snake, hot water can come to your rescue in unclogging your main sewer line. But how? Allow hot water to run through your plumbing system for at least five to 10 minutes. The hot water helps to loosen debris such as deposited grease, oils, or any coatings on the walls of the drains.
It is not a great drain clog remover. Bleach has no effect in dissolving the common culprits of household drain clogs, like hair, food scraps and grease.
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.
Can you leave baking soda in the drain overnight? It is safe to leave baking soda (and vinegar) to work overnight to unclog a drain.
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.
PVC is resistant to many alcohols, fats, oils and aromatic free petrol. It is also resistant to most common corroding agents including inorganic acids, alkalis and salts. However, PVC should not be used with esters, ketones, ethers and aromatic or chlorinated hydrocarbons.
Sulfuric acid is very simple to use and will unclog a drain within an hour, usually within seconds if it's not completely plugged up. Sulfuric acid is naturally occurring and is sewer and septic safe as it is diluted in its journey down your pipes.
Bleach is a common cleaner found in most homes, but is it safe to use in homes with PVC piping? In short, yes. You can safely use bleach to clean and disinfect your PVC pipes, as long as you dilute it first and avoid mixing it with other chemicals.
