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.
Drain Cleaner Can Damage Your Pipes
Drain cleaner is caustic, meaning it will eat away at your pipes — even the tougher types. If your home employs plastic pipes, use the solution sparingly, if at all. It can even eat away at metal pipes. Use the solution once to break up a clog, and you could be safe.
While snaking is generally considered safe for your pipes, it can damage your pipes if they are in bad shape. Homes that have older pipes are more susceptible to this happening as hairline cracks and corrosion occur over time. Surprisingly, snaking your main line can potentially make the clog worse.
The chemicals in drain cleaners can corrode and damage pipes, causing cracks and leaks that can cause further blockages. If the clog is more than the liquid drain cleaner can handle, that'll simply add chemicals to the bigger overall problem.
It is Extremely Corrosive For Your Drains
When your pipes are clogged, Drano will sit on top of the clog, continually reacting and generating heat until the clog dissolves. This can put a great deal of stress on your drains as the heat can cause PVC pipes to soften and even break or collapse.
Damage to Plumbing Fixtures
In addition to the pipes, leaving Drano in the drain for too long can damage the plumbing fixtures. This includes the sink, shower, bathtub, and other plumbing fixtures connected to the drain. These fixtures can become corroded and discolored and can start to show signs of wear and tear.
When you have a clogged drain you might be tempted to fix the problem yourself before calling a professional. Improperly unclogging a pipe can cause damage, make the clog worse, or be potentially dangerous.
The chemicals in Drano may not solve all clogs, and they can lead to a worsening of pipe issues. Drano can build up in a clogged area, and corrode the pipe.
If your auger isn't unclogging a clog, it could be because: The old clog is still attached. Are you using a drain snake that has been used before? Make sure the old clog isn't embedded in the corkscrew end.
Risks of drain cleaners
Chemical cleaners can cause toilet bowls to deteriorate, metal pipes to dissolve, and plastic pipes to heat and warp. While a one-time use is unlikely to cause major damage, it's still a risk you should avoid at all costs.
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.
A manual drain snake, also known as a plumber's snake or a drain auger, is a small boring tool that rotates slowly as it's physically pushed through a stubborn clog. The terminal end of the device is a corkscrew-shaped hook that is fed into a clogged drain or toilet.
Baking soda and vinegar may unclog your drain better than Drano ever could. Start by getting rid of the standing water in your drain. If it will go down slowly, just wait until it's gone. If it isn't moving, use a cup or a spoon to get it out of there.
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.
Using a solution of baking soda, vinegar, and hot water
For more stubborn clogs, a combination of baking soda, vinegar, and hot water may do the trick. Because vinegar is an acid and baking soda is a base, mixing the two will cause a chemical reaction that will create pressure and possibly dislodge the clog.
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.
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.
Will Drano® products hurt my pipes? NOPE. Drano® will not damage pipes or plumbing. Drano® products are powerful enough to dissolve nasty clogs, but they will not harm your plastic or metal pipes, so there's no need to worry.
Simply pour some hot water down your clogged drain and follow it up with equal parts baking soda and vinegar (baking soda first), cover the drain with a plug if you have one, let it sit for 20-30 minutes, then follow it up with more hot water to clear the clog.
If the clog is too deep to unclog with a coat hanger, a plumbing 'snake' or 'auger' is great at removing stubborn clogs and is particularly effective in dislodging hair and other debris. A drain snake is a flexible coil of wire that literally 'snakes' through the drain to locate and dislodge the cause of the clogging.
When a toilet has a clog made of water-soluble materials, it has a chance of slowly dissolving in the water and freeing up the toilet to work properly again. So, clogs that are primarily made of toilet paper can clear themselves.
It's a good idea to schedule an annual drain cleaning even if you don't suspect there's something wrong with your plumbing. Sometimes, clogs can hide deep in your sewer lines and won't become evident until the unthinkable happens.
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.
Reuse every four weeks
To help prevent toilet clogs in the future, you can safely use Drano® Max Build-Up Remover monthly.
