Will Drain Cleaner Damage My Pipes?
Most plumbers will advise you not to use drain cleaners on a regular basis, and this isn’t just because they want your business. Overusing drain cleaners has the potential to cause long-term problems for plumbing systems, but this is highly dependent on the type of cleaner that’s used and how often it’s used. Ideally, drain cleaners should be used sparingly and only for minor clogs, and if possible a mechanical method like a plunger or snake should be tried first.
One big factor that contributes to how much damage drain cleaners can cause depends on their formulation, and this generally falls into one of these categories:
- Caustic: Caustic drain cleaners contain alkaline chemicals like lye or caustic potash. These products work by heating up the grease or food debris that’s stuck in your drain causing it to become thinner and able to be rinsed away with hot water. If overused, these can cause your pipes to corrode and crack.
- Oxidizing: Oxidizing cleaners are made with bleach or nitrates and work similarly to caustic formulas but are more acidic. These are the most common products found in stores.
- Acidic: Acid-based cleaners are often used by professional plumbers because they can be harsh and dangerous if used incorrectly. These are usually made with hydrochloric or sulfuric acid and cause chemical reactions within the pipe which produces heat. These are effective but should only be used sparingly and only with the very worst clogs because they can cause a lot of damage to pipes.
- Enzymes: Enzyme cleaners work by “eating” organic material that gets stuck in drains. In general, these are much gentler on your pipes and won’t cause corrosion, but they do take a lot longer to work.
The potential damage that drain cleaner causes is also dependent on the type of pipe you have. In some cases, it can be more dangerous to use these products with PVC pipes because the heat caused by chemical cleaners can melt and warp them. With metal pipes, you run the risk of corrosion which can eventually cause them to crack or form holes.
Safety Tips
Each product is formulated differently and will have instructions for use which should be followed exactly. However, there are a few general safety precautions you should take when using most drain cleaners:
🧴 Pour the cleaner slowly: Pour it slowly into the drain to prevent splashing.
👓 Wear gloves and goggles: Not all drain cleaners advise you to wear gloves and goggles, but this is a good idea if you’re using a product that can release noxious chemical odors.
💨 Open a window: Chemical cleaners can create odors and toxic fumes when they break down clogs, so turn on a fan or open a window to let in fresh air and keep the air circulating.
🚽 Be careful with the toilet: You have to be especially cautious anytime you have a toilet clog because porcelain can crack and break very easily. If you’ve already tried a plunger, you should try an enzymatic cleaner next which will be gentler on the toilet and your pipes.
👍 Flush out completely: Most directions for drain cleaners call for you to flush the drain out with hot water after you’ve cleared the clog to get rid of all the excess chemicals, and you should never skip this step.
Alternatives to Chemical Drain Cleaners
Because using drain cleaners multiple times in your pipes has the potential to cause long-term damage, there are a few good alternatives you could try first depending on the severity of your clog.
Plunger
A basic plunger is your first line of defense when it comes to loosening clogs, but it should be done right away and won’t be as effective on clogs that have built up over days or weeks.
Drain Snake
There are a few types of drain snakes, and these are often a good option to try before a drain cleaner, especially if you think the cause of the clog is hair. The cheapest and easiest type to use is a flat, plastic hair clog remover. These are usually barbed, around one to two feet in length. They can be used in most drains to grasp onto hair and other debris and then lifted out of the drain.
For tougher clogs or ones that go further into your pipes, you need to use a flat snake or a mechanical snake. These can be purchased from any home improvement store but should be used with caution, especially if you think your pipes may already be broken because they can cause more damage. Also, you shouldn’t use a mechanical snake on toilet clogs because they can easily crack porcelain.
Enzymatic Cleaning Product
Enzymatic drain cleaners use bacteria and enzymes that eat away organic material and they can be very effective. However, these are generally better for smaller clogs or regular drain maintenance since they can require regular applications over several days or weeks to fully dissolve clogs.
Baking Soda and Vinegar
This is a tried and true method and one that’s easy to try since you likely have the two ingredients on hand. Start by pouring one cup of baking soda into your clogged drain followed by one cup of vinegar and letting it sit for up to one hour before flushing with hot water. For extra tough clogs, you can use half baking soda and half salt to get a more abrasive substance and use boiling vinegar. Do note that while boiling vinegar is safe, it can release carbon monoxide into the air, so it should only be done in a well-ventilated space.
Dish Soap
Using plain dish soap is a good alternative to clogs in the kitchen sink because these are most often caused by built-up grease and ordinary dish soap can cut through this. Combine a couple tablespoons of dish soap with 2 liters of hot water and pour it into your drain. Follow up by flushing with boiling water.
Call a Plumber
If you’ve already tried DIY approaches to clearing a drain, have ongoing problems, or are worried you might damage your pipes by continuing to use chemical drain cleaners, you’re likely better off by calling in a plumber. A professional plumber has the tools and industry knowledge to assess difficult situations, address all types of clogs, and take care of them in a way that solves your problems without causing lasting damage.
Using a liquid or powder drain cleaner won’t be the answer for every clogged drain, but it can be an easy and effective solution. First, you’ll have to consider how severe the clog is, what it’s composed of, and in what part of the house it’s in. If you do decide to use a product like this, make sure you’ve read up about alternatives and precautions and follow all the directions.
FAQ
To prevent your pipes from clogging, you should always use drain screens and a hair catcher in your shower. In addition, avoid putting grease or excess food scraps down your drain and regularly flush your drains with hot water.
If you regularly wash your pets in the bathtub, you’ve likely had to deal with a few clogged drains. Luckily, drain cleaners that are formulated especially for human hair will also work on dog and cat hair. This problem can be more pronounced if you're dealing with long dog or cat hair length. For long hair, try a plastic snake tool first. If it becomes an ongoing problem, you could always consider getting one of the hairless cat breeds and you’ll never have to worry about pet hair again!
How long a drain cleaner takes to work really depends on the product. Some of them can work in as few as one to five minutes, others take up to an hour, while still others should be used overnight or even for multiple days at a time.
