6 Reasons to Ditch Harsh Chemical Drain Cleaners

A clogged drain is among the most common plumbing problems. Instead of calling a professional to clear the blockage, many homeowners opt to buy liquid drain cleaners. While these products are readily available at your local hardware store, the best approach is to leave them on the shelf. While liquid drain cleaners seem like an easy solution to plumbing clogs, they can be hazardous and are generally ineffective in the long run.

Let’s take a closer look at why you should leave harsh chemical drain cleaners out of your home’s cleaning supplies.

6 REASONS TO STOP USING CORROSIVE CHEMICAL DRAIN CLEANERS

They Emit Unhealthy Fumes

Before you decide to grab a bottle of drain cleaner, first consider the ill effects it can have on your health. As soon as you remove the cap, the product will release toxic fumes. This is why these cleaners (and many other household cleaning products) should only be used in well-ventilated areas. Failing to at least crack open a window puts your health at risk.

After inhaling drain cleaner, some symptoms can happen almost immediately. The potent fumes can burn your mucous membranes and irritate your eyes. People who have an underlying respiratory condition are even more prone to experiencing breathing problems.

They Can Cause Serious Burns

Be extremely careful when using store-bought drain cleaners. Many are formulated with highly concentrated sulfuric acid, which can burn your skin, irritate your mucous membranes, and can even cause blindness. Research shows that roughly 3,000 people a year suffer injuries related to the use of drain cleaners. There are many cases in which the person required hospital care. You can read more about the effects of sulfuric acid in this public health statement published by the Agency for Toxic Substances and Disease Registry, a federal public health agency within the U.S. Department of Health and Human Services.

Even if you’re extremely careful when pouring the product down your drain, trouble can still arise. As the acid hits the water, it may cause a chemical reaction sooner than you might expect. The acid could then splash onto your skin. Keep in mind that drain cleaners are strong enough to eat through clothing.

Drain Cleaners Are Often Ineffective

Although some drain cleaners are promoted as being effective, the overwhelming majority of these products don’t work well in the real world. They have a difficult time removing blockages deep inside your drain-waste system. When drain cleaners do appear to work, the results typically are only temporary. After a few weeks, another clog tends to emerge. An experienced plumber can actually fix the problem as opposed to just masking it.

There are certain things that a corrosive chemical drain cleaner simply can’t do. For example, hair blocking a pipe must be manually removed. You will literally be pouring money down the drain.

They Can Weaken Your Pipes

You can extend the life of your plumbing system by avoiding the use of chemical drain cleaners. Over time, the abrasive ingredients gradually start to corrode the pipes, especially if the cleaner is unsuccessful in removing a clog and only sits on top of it instead. Leaking can become a real concern.

To prevent unnecessary damage to the pipes, opt to hire a professional plumbing company to clear your drain. The technicians have several specialized, chemical-free tools on hand. A plumber can eliminate most clogs using a technique called snaking. Hydro-jetting can prove to be an even better long-term solution for pipes with multiple obstructions and a lot of grime coating their walls. This process involves using powerful streams of water to blast away clogs, grease, sediment, and anything else that might be obstructing your drains or sewer line.

They Can Damage Your Septic Tank

Your home’s septic tank is responsible for collecting waste. While a well-maintained septic tank can easily last up to 40 years, frequent use of chemical drain cleaners will shorten its life. Allowing a plumber to clear your drain can save you a lot of stress and money.

A septic tank uses bacteria to break down and consume waste. Unfortunately, the toxins in chemical drain cleaners can kill the bacteria. What’s more, the chemicals could leak into the ground and contaminate the surrounding environment.

A Danger to Children and Pets

If you have children at home, never make the mistake of failing to store a chemical drain cleaner properly. The natural curiosity of a toddler may cause them to investigate the colorful bottle. No parent wants to jeopardize the safety of their child. Curious pets are also at risk of being poisoned if they chew through the plastic container.

I have used green planet a few times. One time was an emergency clog, They were prompt and reasonably priced. Their most recent visit was planned work that was needed on my older home. They were honest and fair, did quality work, answered all my questions, explained my options and gave me sound advice. Green planet is who I call whenever I have a plumbing need. They have always done right by me

Justin rocks. He is incredibly knowledgeable and professional. Keeps it clean and courteous. As a contractor, I have had him and the green planet team rough in and trim out multiple jobs and even work on my own home. Couldn’t recommend a better plumber.

I am SO relieved to have found Green Planet, a plumber I can trust. For years, I had a colleague in my business networking group who did amazing work without bait and switch and ridiculous markup, but he retired. Green Planet came recommended by my next door neighbor. They first did routine maintenance on my rental unit, but this week I called them with a bit of urgency. My water shut off valve snapped off, thankfully when I was not in an emergency, like a burst water pipe. I decided to have them also fix a toilet that on occasion would run for hours and an exterior spigot that was shooting water the wrong direction. Technician arrived within 45 minutes, took a look at everything, and provided a written estimate. He discussed what could go wrong once we removed drywall and fixtures, but made every effort to work diligently to avoid these scenarios. One of the main issues would be the presence of old, corroded, pipes versus modern pex. He had the spigot and toilet fixed quickly and then focused on the main project. Steady lines on the drywall removal help make it easy for me to replace that. Once done, even with a quick parts run to the warehouse, he was wrapped in about 90 minutes with everything looking great. We discussed my aging hot water heater, and options to install an upgraded toilet, so I can make plans to budget those projects down the road. Such a relief to have a company I can trust after some bad experiences with the big brands you see on TV (I see how those types of companies can afford big splashy campaigns).

We had a really great experience with Eddie from Green Planet. We had a shower faucet that was leaking, and also the handle had completely separated from the faucet. Green Planet doesn’t change for an estimate which was really appreciated, and also their estimate to replace the cartridge in the faucet was less than half what other companies had charged us for the same service. We were weighing whether to replace the entire faucet, and he gave us helpful thoughts on that as well. We chose to go with a cartridge replacement because to replace the faucet they would have had to open up a wall. We didn’t have a dry waller in mind. The repair was fast and works great. Thanks so much Green Planet!

It was a pleasure to have Justin and Henry replace our hot water tank and snake out our kitchen sink drain. They were very pleasant and easy to talk to and made sure all questions and concerns were answered. Very rapid response, I called for an estimate and they were here the next day. I approved the work and they were able to start the work the following day. They arrived early and got right to work. They protected all exposed surfaces before starting. When complete they made certain that we understood how to operate the controls on the tank and explained all they did. All at a reasonable cost. We definitely will call Green Planet Plumbing again for any future plumbing needs.
