Removing Clogs From Drains

A clogged drain is a household plumbing emergency that is very annoying to deal with. Usually, it starts as a minor clog, which if unattended to will progress into a major clog and plumbing damages that might be costly to repair. Drain cleaners, a plunger and plumbing snakes are enough to take care of most drain clogging.

This article will cover the causes of drain clogs, the best types of drain cleaners and the ones suitable for getting rid of different kinds of drain clogs.

Signs Of Drain Clogs

If your drain has clogged, you will notice several signs indicating so. The signs of a clogged drain include the following:

  • Flood of water around the area of clogging
  • A slow water drainage
  • Corrosion on the drain
  • Sewage backup

Causes Of Drain Clogs

Here are some of the most common factors that can contribute to your drain getting clogged.

Soap Residue

Soap residue is one of the most common causes of laundry and bathroom drain clogs. Most traditional bar soaps are made of grease or fat and the minerals in water (hard water especially) combine with fat or grease in the soap and leave behind a hard residue known as soap scum. The scum reduces the diameter of the pipe, slows down the movement of water through the drain and eventually clogs the drain.

Replacing your traditional soaps with soap-free washes can help prevent this type of drain clog.

Food Waste

Food waste is a common cause of your kitchen drain clog. Therefore, if your kitchen drain clogs often, it is probably because of food particles like vegetables, eggshells and bone fragments going down the kitchen sink and clogging the drain. This happens regardless of whether you have a garbage disposal or not.

Simply throw your food leftovers into the trash and keep food particles away from your kitchen sink to prevent the drain from getting clogged.

Lumps of Hair

Human hair and animal fur can easily block the drain of your bathtub, shower or bathroom sink. Both hair and fur can combine with grease from soap and other sticky substances to form a clog leading to a drain blockage.

You can put a perforated drain hair catcher in your bathroom drain to keep hair and soap scum from entering the drain, which will help prevent the drain clog.

Grease, Fat, and Oil

Grease, fat and oil are common causes of a drain clog, especially your kitchen sink drain. They go down the sink in liquid form, solidify and then form a clog in the drain pipes.

To prevent this type of drain clog, avoid pouring oil, fats and grease down the sink. Instead, pour them into containers, allow them to cool off and dispose of them in solid forms.

Toilet Paper Build-Up

Toilet papers should not clog your toilet when used in a moderate amount. However, flushing excess toilet paper down your toilet can clog the drain. This is because huge lumps of toilet paper take a longer time to get dissolved.

Ensure that you use toilet paper in moderation and also supervise how your kids use it to prevent this type of drain clog.

Hygiene Products

Flushing hygiene products like sanitary pads, cotton balls, diapers, tampons and wet wipes down your toilet drain can clog it. Unlike toilet paper and human waste, these hygiene products do not break down or get dissolved when flushed. For instance, when a tampon comes in contact with water it absorbs it and swells up instead of dissolving like toilet paper.

It is advisable to dispose of your hygiene products and dental floss into the trash.

Different Drain Cleaners For Your Drains

These are the most common types of drain cleaners used. They are quick, easy to use and most of these cleaning products are usually liquid formulations.

Chemical drain cleaners clear clogs by dissolving the substances causing the drain blockage. They are commercially available in household supply stores and come in different sizes and brand names. The choice is yours!

Types of Chemical Drain Cleaners

Acidic Drain Cleaners

This category of chemical drain cleaners works by exacting acidic effects on the clog to dissolve it. They contain sulphuric or muriatic acid that is powerful enough to break down tough drain clogs caused by soap, hair, food and even paper-based clogs. They exact their effects in about 15-30 minutes.

They are generally safe for drains with newer plastic or metal pipes like copper in sinks, showers and toilet drains.

NOTE: Ensure to use safety gear like safety glasses, rubber gloves, nose masks and protective clothes when handling acidic drain cleaners as they can burn and irritate your skin, eyes and lungs.

Enzymatic Drain Cleaners

Enzymatic drain cleaners contain enzyme-producing bacillus, bleach nitrates or peroxide. They are a little harsher than acidic drain cleaners. They are suitable for monthly use to prevent drain clogs and are usually used to clear a soft drain clog. They are also gentle and non-corrosive to both old and new plastic pipes, metal pipes inclusive.

These cleaners can take up to 24 hours or more to exact their drain clearing effects. They do not contain any toxic and harmful ingredients making them a good drain cleaning option.

Caustic Drain Cleaners

Caustic drain cleaners contain alkaline chemicals like sodium hydroxide. They work by converting the drain clog into a soap-like substance that readily dissolves in plain water. They are suitable for clearing sink, shower and bathtub drains clogged with food, grease and soap scum. They are unsuitable for getting rid of toilet clogs as they cannot handle toilet paper.

Moreover, they are less acidic and corrosive but require you to wear protective gear while handling as they can burn and irritate your eyes, skin and nose on contact.

Our Customers

Christopher Chow

I called Hero Plumbing to unblock a shower drain and was unable to get a quote over the phone, but Sam the owner was here same day. After his first try, he made quick work of the blockage. I opted to also get the acid cleaner stuff poured down. Sam had run out, but made a trip to go pick some up to finish the job. If you opt for this treatment make sure you can easily air the bathroom as it’s extremely strong and produces a lot of fumes. Great Service and Honest Pricing.

I knew Sam when he was working alone. And from the first time I was pleasantly surprised by his work. A little later I found out that he has his own business. I am very happy about that. And I am very glad for myself that I have such a company that I can always rely on.

Thank you for your work. People need you very much.
