Chemicals mix together to create heat at near boiling temperatures that are supposed to speed up the decomposition process. Furthermore, when mixing with grease and water, the chemicals in Drano create soap and bubbles to loosen the clog.
Product may foam up from drain. This is normal. If foam is visible after use, rinse foam completely down drain with water. Do not use product with a plunger because Drano® Dual-Force® Foamer may still be present.
The foaming action fills the pipe and thoroughly clears its walls, dissolving gunk. A blast of hot water flushes away what's left of the clog.
Plunge it Out
When Drano won't go down the drain, grab a plunger instead. Many people think that these are only good for toilets. However, they can create suction that can dislodge your clog. If you're using a plunger, choose one that is suited for the type of clog you're dealing with.
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.
You can use Drano® Clog Removers to unclog a kitchen sink, bathroom sink, shower or clogged bathtub, but DO NOT use them in toilets. 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.
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.
Drano is not only ineffective, but it's also extremely damaging to your plumbing system. The heat created by the chemical reaction is more than your drains are designed to take. Corroded, aging plumbing can easily breakdown. Pipes can split and the glue holding them together can disintegrate.
Using Drano in the toilet can also hurt you. For example, let's say you used Drano and the clog isn't going anywhere, so you decide to try plunging it. While doing so, you run the risk of accidentally splashing the sitting Drano on your skin, which could cause a burn.
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.
Yes, the heat these chemicals produce will break down the remnants of a clog, but likely only push them farther down your system to form a more dense clog in a harder-to-reach section of your plumbing. This leads to repeat clog offenses, repeat pouring, and the eventual ruin of your plumbing system.
Yes, it is possible for drain cleaners to end up making a clog worse. This can happen for a few reasons. First, the chemicals in drain cleaners can corrode pipes and cause damage over time. This can lead to leaks or even bursting, which can make a clog worse by creating additional blockages.
While the phosphoric acid found in cola can help alleviate some minor clogs, carbonated beverages are certainly not the ideal drain cleaner. Better DIY methods include a baking soda/vinegar mixture, a plunger, or a plumber's snake.
The foamer works better than regular Drano, unless you have a completely clogged drain that doesn't move at all.
Not only will it not fix your clog, but it will actually make it worse. Over time, drano can harden and become like cement. This will eventually require much more expensive repairs.
The best way to clear that clog is by pouring Drano® Max Gel Clog Remover straight over the drain (even if there's standing water). It works by dissolving the remaining hair and gunk—and boom! It works within minutes, and keeps your drain flowing smoothly!
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.
Does this particular clog seem bust-up proof? If standing water remains, use Drano® Max Gel Clog Remover. It pours straight through the water and attacks the clog directly.
Some of the best Drano alternatives include using a plunger or pipe snake, soap or salt mixed with boiling water, or baking soda and white vinegar. Also, for maximum effectiveness, you can combine several of these methods together to get rid of the clog.
If using a plunger or drain snake does not clear your clog, this is a sign that it is time to call a professional plumber. Considering the risks that come with using Drano, hiring a plumber to clear the clog for you will still be the safer and cheaper option in the long run.
Most plumbers will advise you not to use Drano to unclog your drains. This is because the chemical compounds are hard on your pipes, causing corrosion and other long-term damages. Drano is designed to continually react and generate heat within your drain until the clog dissolves.
Single Use, Not Frequent Use
Because of the chemicals found in these types of products, you could cause irreparable damage to your pipes. In most cases, a single use of Liquid-Plumr or Drano will not cause any issues with your pipes, though you should avoid using them in your toilet.
The most common chemicals used to unblock sinks are Drano, hydrochloric acid, or caustic soda. Chemical drain cleaners can be effective at removing even the toughest clogs. They come in different forms, such as powder, liquid, or gel, so be sure to buy one that best suits your situation.
