The harmful chemicals in Drano can end up being corrosive to your pipes. Drano has been known to cause toilet bowls to crack, soften and break PVC pipes and break older corroded pipes. Over time, the continued usage of Drano can lead your pipes to corrode, crack and eventually fail.
Corrosion
When Drano is left in the drain for too long, it can cause corrosion of the pipes. 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.
A liquid drain cleaner can sometimes make the clog worse over time if you don't use it properly according to its instructions or use it too much. The chemicals in drain cleaners can corrode and damage pipes, causing cracks and leaks that can cause further blockages.
Although plumbing chemicals like Drano are designed to break up clogs and clear your pipes, they often make a clog worse for homeowners.
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.
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 can build up in a clogged area, and corrode the pipe. With repeated use, these chemicals may eat their way through a pipe, and cause a leak or a collapse of the system. Homeowners and plumbers should avoid repeated use of chemical cleaners. Safer plumbing alternatives can be chosen to resolve most drain issues.
For use on clogged or slow-running drains, pour half of the bottle (32 oz. size) slowly over drain. For extremely slow-running drains or complete clogs, pour in entire contents of 32 oz. bottle.
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.
It is Extremely Corrosive For Your Drains
While it is dissolving your clog, Drano can also quickly eat away at the glue holding your pipes together, leading to a potentially costly leak.
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.
Bottom line: Liquid Plumr and Drano should be used sparingly, if ever. That said, using a chemical drain cleaner once or twice probably won't result in significant damage, but you are taking a risk every time you use one.
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.
Using Drano once or twice is nothing to be too concerned about, and it likely won't cause damage to your pipes. However, if you find that a clog is showing up repeatedly, this can be a sign of deeper plumbing issues that should be addressed by a professional.
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. It is recommended to use a camera and a snake to attack the cause of the clog.
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!
Clogs can also be caused by buildup in the third, lateral section of the pipe. Drano® Max Gel Clog Remover is effective on these clog types as well. Keep some on hand for its reliable clog-busting power!
Use ½-1 cup of baking soda and 1 cup of vinegar, plus a bit of water if you want to dilute things a little bit more. Pour it down the drain and let it sit for 30-60 minutes. Sometimes, this mixture can break up clogs that even Drano can't touch!
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.
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.
