What Do Plumbers Use to Unblock Drains?

What do plumbers use to unblock drains UK

When it comes to drain cleaning, there are several products that plumbers use to get the job done. These products range from Hydrochloric acid and enzymes to Plunger, Caustic soda, and enzymatic unblockers. Let’s take a look at the most common drain blockages to give you a better idea of what to do.

Hydrochloric acid

When a drain is clogged, plumbers often use hydrochloric acid to unclog it. This chemical is made by combining hydrogen chloride gas and water. While it is commonly used as an acid in unblocking drains, it has other applications in manufacturing, such as batteries and photoflash bulbs. It is also found in the human stomach, where it is important for digestion.

Although this acid is highly effective at clearing clogged drains, it also has a few risks. It is strong and potentially hazardous, and it may damage pipes and cause chemical burns or blindness. The acid can also produce chemical fumes that irritate people. Moreover, it can get into the water supply and should therefore not be used by homeowners or children.

In addition to using hydrochloric acid to unclog drains, plumbers can also use other stronger chemicals to clear them. While this acid is highly effective, it can also cause damage to plumbing systems, so it is best to use an acid that is biodegradable.

Enzymatic unblockers

Enzymatic unblockers are what plumber use to clear clogged drains. They contain bacteria cultures and concentrated enzymes to dissolve solid blockages in pipes. Enzymatic drain cleaners are safer than chemical drain cleaners, and they are suitable for household use. However, you should be aware that drain unblockers may contain harmful chemicals that are harmful to your health. Therefore, you should only use them if you are sure you can safely use them.

The chemical-based unblockers are best used in the case of heavy blockages such as hair. Their caustic content helps dissolve clumps of hair and soap scum. You can also use hair snakes to reach the blockage. However, be careful when using caustic soda products, as they may cause toxic overflows. Enzymatic unblockers are gentler, containing concentrated enzymes and bacteria cultures. They can break down organic substances, which make them more effective in clearing drains.

Another option is to use a drain unblocker, which is a gel-like liquid that dissolves obstructions in pipes. This type of unblocker is ideal for unblocking sinks and toilets, and is safe for plumbing. These liquids are available in two categories: enzyme-based and chemical-based. Enzymatic unblockers break down clogs and are safer for the pipes than chemical-based unblockers. However, they may be more expensive, so if you have a large family, it may be best to purchase a larger bottle.

Caustic soda

If you are having difficulty unblocking your drain, you can use caustic soda to dissolve the blockage. However, this chemical can cause serious damage if used improperly. To use this chemical, make sure that you are using a small amount. It can be extremely dangerous to use a large amount and may not work.

Caustic soda is very corrosive, so it is essential to wear protective gear while working with it. Always use gloves and work in an area that is well-ventilated. The chemical released from caustic soda can cause burns if breathed in. Caustic soda works by causing a chemical reaction in the drain that breaks down organic materials.

Caustic soda can also be used to unblock sinks and toilets. The acid in the caustic soda breaks up the clogging material. Caustic soda is a strong chemical, so you must wear protective gloves and glasses while using it. When you mix it with water, it will create a fizz and heat. Once the soda has dissolved the blockage, you can insert a drain snake into the blocked drain and let it work. Repeat the process if necessary.


Plumbers will tell you that plungers are an essential part of their toolkit. Without them, they would be like joiners without hammers. This small device can unblock a wide range of drainage problems, including toilets and sinks. However, not every household owns a plunger and not all homeowners know how to use it correctly. Fortunately, learning how to use a plunger can save you a great deal of money in the long run.

In order to use a plunger correctly, you need to make sure that the drain is not plugged. The plunger should break the blockage so that water and air can pass freely. It is essential to hold the plunger shaft for 30-60 seconds in order to achieve this.

An ordinary plunger may be used for unblocking drains. It creates force in both directions to break up the blockage. A plumber may use a manhole or corkscrew cable if the blockage is located at a greater distance.
