Chemical drain cleaners can remove some blockages, but their corrosive ingredients also create serious safety risks. They can burn skin and eyes, damage tissue, release hazardous fumes when mixed with other cleaners, and leave dangerous chemicals inside a blocked drain. A slow or blocked drain also may have a cause that chemicals cannot address. Providence Plumbing of the Carolinas offers drain cleaning in Raleigh, NC with methods designed to address the obstruction rather than repeatedly adding harsh chemicals to the line.

The Chemicals Can Cause Serious Injuries

Many non-enzymatic drain cleaners contain strong acids or alkaline chemicals such as sulfuric acid, hydrochloric acid, sodium hydroxide, or potassium hydroxide. Poison Control reports that concentrated drain cleaners can cause severe chemical burns and permanent tissue damage.

Skin and eye contact are not the only concerns. A product can splash back from a drain, especially when too much cleaner is poured into a completely blocked line. Poison Control specifically identifies splashback as a way these products can cause chemical burns.

Mixing Cleaners Can Create Another Hazard

Never combine drain cleaner with another cleaning product. Chemical reactions can produce hazardous fumes or other dangerous reactions. Manufacturer safety instructions for common drain cleaners also warn against using different cleaners together.

That warning includes products already sitting in the drain. If one cleaner has already been used on a clogged drain, adding another product can create an unpredictable chemical reaction.

Keep these basic precautions in mind:

• Never mix drain cleaners with other household chemicals.
• Keep the product away from children and pets.
• Follow the label directions for the specific product.
• Avoid contact with the liquid or residue.
• Tell our plumber if chemical cleaner has already been used.

A Chemical Cleaner May Not Solve the Actual Blockage

Chemical cleaners work by breaking down certain materials inside a drain. They are not designed to remove every type of obstruction. A blockage caused by an object, for example, requires a different approach.

EPA guidance lists a plunger or plumber’s snake as alternatives to chemical drain cleaner. When the same drain keeps clogging, our drain cleaning services can address the obstruction using mechanical equipment or another method suited to the line and the type of blockage.

Do Not Use a Plunger After Using Certain Chemical Cleaners

A drain that remains blocked after chemical treatment needs extra caution. Some manufacturers specifically warn against plunging during or after product use because chemical cleaner may still be present and can splash back.

If a cleaner has already been poured into the drain, tell us what product was used before we begin service. That information gives our plumber an important safety detail before handling the affected line.

Chemical Drain Cleaners Are Also Household Hazardous Waste

The EPA classifies drain openers among household hazardous waste because they can be toxic, corrosive, ignitable, or reactive. The agency advises against pouring household hazardous waste down drains or into storm sewers.

Unused product should not simply be poured away because you no longer need it. Check your local household hazardous waste program for disposal instructions.

Frequently Asked Questions About Chemical Drain Cleaners

Q: Can chemical drain cleaners damage plumbing?

The safest claim is that they introduce highly corrosive chemicals into the plumbing system. Their labels also contain specific restrictions for certain materials and applications, so the product instructions should be followed closely.

Q: What should I do if a chemical cleaner did not clear the drain?

Do not automatically add another product or plunge the drain. Tell the plumber which cleaner was used and follow the product’s safety instructions.

Q: Is a recurring blockage a reason to call a plumber?

Yes. Repeated blockages can require mechanical removal or further evaluation instead of another chemical treatment.
