The Best Drain Unblocker - A Buyers Guide

Blocked drainer? Here is the ultimate buyer’s guide on choosing the best drain unblocker. We’ve also included a few precautionary measures you must use when applying a drain cleaner to achieve optimum results while ensuring your ultimate safety. 

What is the Best Drain Unblocker?

A drain unblocker, often known as a drain cleaner, is a chemical or enzyme-based product designed to unclog laundry drains, wastewater drains, or sewer pipes.

Enzyme-based products comprise of bacteria that eats away organic clogs. They are best for hair and paper clogs. On the other hand, chemical drain cleaners are classified either as caustic or acidic. These are quicker and will handle more challenging clogs. However, you must wear the right attire and protective gear when using any chemical drain cleaners to avoid irritations to the eyes, nose, and skin.

Sometimes a drain unblocker may refer to the tools used to unblock a drain, such as a drain auger, plunger, or plumber’s snake. Some people may also use the term drain cleaner (or unblocker) to refer to the plumber or person who cleans the draining system.

Do I Need the Best Drain Unblocker?

Imagine this for a second. Your shower is flooded. The tub isn’t draining the water as it should. The toilets won’t flush. And even worse, the stinking odour from the kitchen sink is unbearable.

Sounds terrible, right?

Well, the above scenarios are almost inevitable. Every household will face one of the above challenges from time to time. At these times, you can either call your plumber every time there is a blockage. But the cost of hiring a professional plumber can add up pretty fast.

That’s where the best drain unblocker comes in! These products are a lifesaver. You can apply them by simply following the provided instructions. And they’ll work like magic. Below we look at the main benefits of drain unblockers.

1. Easy to use – No machinery is required. Simply pour the liquid into the drain system and wait for it to perform its magic.

It eliminates foul smells. Any clogs in your drain result in bad smells, which become stronger as the build-up increases. Eliminating these smells means no more stinking odours from your sink

2. Saves you money. The cost of hiring a professional plumber is significantly higher than that of using the best drain unblocker.

3. Quicker drainage. Nothing is as irritating as a slow draining sink or tub. Well, with the best drain unblocker and frequent drain cleaning, you’ll enjoy faster drainage all year-round.

5. Longer pipe and drain system life. A clogged drain often causes corrosion on the pipes, resulting in leakages, thus shortening the lifespan of your gutter. But by using suitable drain cleaners, your pipes will last for the duration they were meant to last.

But to reap all the benefits of your drain unblocker, there are a few safety measures you must have in mind.

  • Follow the manufacturer’s instructions to the letter. No drain cleaner is like the other. Each is a unique formula with a unique set of instructions. Thus, the first step before using any product is to check the label. And most importantly, ensure that the drain unblocker stays in the drains for the specified duration.
  • Put on protective gear. Always wear eye protection and gloves when applying the drain cleaner.
  • Be careful when pouring the drain unblocker to prevent spillage. Most strong drain cleaners comprise harsh chemicals that can damage your floors and other surrounding surfaces such as marble, stone, stainless steel, etc. Thus, take extra care to ensure no spillage.
  • Never combine drain unblockers with other detergents. All drain cleaners work by reacting with the substance causing the blockage. However, each formula will, of course, comprise unique substances. When the chemicals from two drain cleaners react, they may result in the formation of harmful gases. The worst-case scenario is an explosion.

To that effect, should you try a particular cleaner and it fails, don’t be tempted to try cleaning with another product immediately. Instead, wait for the first formula to clear and flush away entirely before you can try another one.

  • Rinse the drain properly after using a chemical-based unblocker. The instructions on how long you should rinse the drain and the recommended water temperature to use while rinsing is found on the provided instructions of use. Follow these to the letter.
  • Use enzyme-based drain cleaners for toilet blockage. 

Key Features of the Best Drain Unblocker

1.Type of Blockage

The best drain unblocker to clear your clogged sink will depend on the kind of blockage in the sink. That’s because different cleaners are designed to breakdown or dissolve various types of clogs. And the type of clog varies depending on what’s causing the clog.

If you are looking to unblock a bathroom sink, the clogs you are tackling are probably hair and scum. Here, choose an acidic drain cleaner.  On the other hand, blockage in kitchen sinks is often caused by grease build-up. An alkaline drain cleaner will suffice.

2. Duration of Exposure

Some cleaners are super powerful and can break down the clogs in your sinks in as little as 15 minutes. Other formulas must be left overnight to work. The best option will depend on how much time you have at hand.

3. Safety and Compatibility

Chemical drain unblockers often contain acids and bases that react with the clog in your drain to unblock it. And although they are super useful, they are not always safe for all types of drainage systems.

It’s best to always check out the compatibility of any strong drain cleaner to your system, especially if you have a septic tank, plastic pipes, or garbage disposal. Some great options are made to be gentle on plastic pipes and are safe for use even in homes with septic tanks or plastic pipes drainage systems.

If you’re unblocking a sink that’s easily accessible to your pets and children, the best is to choose mild options that do not pose any danger to your kids’ curious hands.

4. Ease of Use

The sight of having a clogged drain is already enough source of headache. Thus, if a drain cleaner comes with a whole volume of instructions, is complicated to use, and takes too long to work, it’s best to check out the next available options.

The best drain unblocker should be easy to use. Better yet, choose one with pre-measured doses for one time actions.

5. Environmental Impact

The content in our drain system eventually ends up in the environment. Thus, if you’re conscious of the impact your drain cleaning process has on the environment, you need to ensure the products you use are kind to Mother Nature.

Of the three types of drain cleaners mentioned above, the best drain unblocker for the environment is an enzyme-based option. That’s because they eat the clog without causing any chemical reactions.

6. Purpose

Why do you need to buy the best drain unblocker? Generally, a drain unblocker can either clear or prevent the formation of clog. If you are looking for a product to avoid clog formation in your drains, choose an enzyme-based product. These are mild and will work flawlessly. But if you are dealing with a notorious total blockage, an acidic or caustic option may be your best pick. 

How Much Should You Pay for the Best Drain Unblocker?

The best drain unblocker can cost from as low as £6 up £15 depending on the type and brand. However, with enough prior research and by reading online reviews of the best drain blocker, like this one, you can always get the best value for all your purchases. 

Types of Drain Unblockers

There are three popular types of drain unblockers. Each type is ideal for different blockages, pipes, and drain locations.

1. Enzymatic drain unblockers. These types comprise a unique blend of enzymes and bacteria such as bacillus that eat away the clog in your sinks. However, most of them need a longer duration to function and are the best preventative to prevent clogging.

You can use enzymatic drain cleaners to unclog blockage caused by a soft material such as paper or hair. And due to their gentle nature, these formulas are ideal for use in showers, toilets, sinks, and tubs. That’s because they’ll not corrode old or new plastic

And the best part? Enzymatic drain cleaners do not contain harmful ingredients that may irritate the skin. You can use them without wearing gloves, an eye shield, or any other protective gear. In fact, these cleaners are considered the safest options for both you and the environment.

2. Caustic drain unblockers. These include sodium hydroxide or potassium hydroxide and are ideal for dissolving scum, grease, and soap. You can use them in showers, kitchen sinks, or tubs. However, these drain cleaners are not recommended for toilets as they are inefficient in decomposing paper clogs.

Alkaline cleaners are faster than enzymatic formulas and will work in 30 minutes or less. They work by raising the clog’s temperatures, breaking down or melting the material responsible for the blockage.

Because this process involves heat production, it is recommended that you only use a caustic drain unblocker in newer plastic or metal drains of less than 20 years old. Plus, it would be best only to use metal pipes made out of either copper or stainless steel. That’s because alkaline formulas corrode older plastics or metal pipes made out of galvanized steel, brass, or aluminium chrome.

Unlike acidic drain unblockers, which we shall look at next, caustic cleaners are odourless and less toxic. However, they can irritate the skin and eyes. The fumes, too, are irritating to the nose. Therefore, you must wear protective clothing, including gloves, eyeglasses, respirators, and an apron for full-body coverage.

3. Acidic drain unblockers. As the name suggests, these are made out of acid. When the acid is mixed with water, the acid hydrolysis process causes a chemical reaction that dissolves any material that may be clogging your pipes.

Their concentration is powerful enough to dissolve food, hair, grease, paper clogs, scum, and more. Plus, they are fast-acting and will clear all clogs in just 15 minutes (or less). Are you looking for the best drain unblocker for that heavily clogged tub, sink, toilet drains, or shower? You can never go wrong with an acidic drain cleaner.

However, note that these are only safe for unclogging newer plastic or metal pipes. But never use these formulas on galvanized steel, aluminium chrome, or stainless steel. The acids in the product will quickly react with the above metals, which will damage your pipes.

Acids are known to burn skin and are irritating to the lungs and eyes. Thus, you must ensure that you’re in the right safety gear before applying these products. That includes long-sleeved overalls, gloves, safety glasses, and a respirator.
