How to Unclog a Large Pipe in the UK

How do you unclog a large pipe UK

Several solutions are available to unclog drains, including boiling water. First, use a bucket underneath the pipe to catch spilled water and debris. Next, use a plumber’s wrench to loosen the pipe’s slip nuts. Once these are loose, pour boiling water into the pipe to unclog it.

Baking soda

If you’re having trouble with a clogged pipe, you can try an inexpensive homemade drain cleaner. It contains baking soda, cream of tartar, and salt. When combined with hot water, they will dissolve stuck-on gunk in your drain. You can also use vinegar, which will help dissolve greasy substances and clear clogs.

A simple solution of baking soda and vinegar will usually unclog most drains, but if the blockage is particularly stubborn, you may have to add up to half a cup of baking soda. This solution will fizz up a little bit, but it should disappear in a few minutes.


Using hot water and vinegar to unclog a drain can help to break up greasy substances that have become lodged in your pipes. While this is an effective way to remove clogs, hot water can also damage PVC pipes. In such cases, you can use a mixture of hot water and washing up liquid. The mixture can be used in the same manner as commercial drain cleaner.

This mixture has two main effects: it breaks down organic substances and creates carbon dioxide gas, which is a strong oxidizer. The resulting gas pushes the clog down the pipe. It also cuts down odors.

Drain rods

You can purchase drain rods at hardware stores or DIY stores. Often, these rods can clear a small blockage quickly and easily, but if you’re unsure of your plumbing skills, you should call a plumber. You can also use a pipe wrench to remove the obstruction and reattach the pipe manually.

Drain rods come in lengths up to a meter. They screw together and are flexible. They should be inserted into the pipe until you feel resistance. Then, use the rod to push back and forth to break up the blockage. Make sure to clean the rods before using them to avoid contamination.

Drain rods can unclog domestic and toilet pipes. They can be bought in stores or online. Once inside the pipe, push the rod through the blocked area while rotating it clockwise to dislodge the blockage. Repeated pushes with the rod can help loosen the blockage and allow the jet to pass through it.


Plungers can be used to clear clogs in large pipes. But they’re also great for unclogging pipes with clumpy buildup. In some cases, a plunger won’t do the job. For these situations, a drain snake can be useful. These tools are long pieces of steel with a handle attached. They are used to dislodge buildup in pipes, and their front end is equipped with an auger, usually in the shape of a spiral. They can be purchased from most hardware stores.

When using a plunger to clear a clogged pipe, the initial plunge shouldn’t be too forceful – the main purpose is to force air out of the plunger’s bell. However, once all the water is out, you can use more force. You may have to plunge several times before you find the right pressure for the blocked pipe. It’s important to remember that you should use enough water to cover the plunger before you start to plunge.

Hydrochloric acid

Hydrochloric acid can be used to unclog a large pipe if you have a clogged toilet or drain. This acid can dissolve the blockage if you pour it into the pipe and wait for two to three hours. After that, you can flush out the pipe with four gallons of water. You can also use a plunger or ordinary jet wash to clear any remaining blockage.

However, hydrochloric acid, also known as muriatic acid, is extremely corrosive and can damage pipes if used incorrectly. Generally, you should only use it in emergency situations or under the supervision of a plumber. This is because the chemicals can be harmful to the environment and your health. Also, you should never mix hydrochloric acid with other chemicals.
