Boiling Water Boil at least a quart of water and slowly pour it down the drain in smooth spurts. You need to give the water time to work its way through clogs and destroy blockages, so don't pour it all at once.
Unblocking Drains with Soda Crystals
If your drain isn't completely blocked and is still slowly draining, you can consider using soda crystals or caustic soda to clear your blockages.
Another method you can use to unblock an outside drain is using sodium hydroxide (caustic soda). Drop some of it in your drain along with some water. This will cause the debris causing the blockage to rise to the surface where you can fish it out.
Use Croc Crete to Remove Hardened Cement
This is the best method of removing hardened concrete from a drainage system. Croc Crete is a cement softener that attacks concrete at its core. It transforms cement back to its liquid form, allowing you to work it through the drain.
You can use cutters, nozzles, cable machines and jetters for severe blockages. Snaking the line with a root cutter is one of the most common ways to remove roots. But be sure the heads and bits used on the ends are specifically designed for cutting out roots.
Boil a kettle full of water and, wearing long sleeve gloves, goggles and a mask, pour it down the outside drain being careful not to cause any to splash back onto your skin. If hot water doesn't work, you can try using caustic soda, also known as sodium hydroxide.
Pour hydrochloric acid (sometimes also known as muriatic acid) into the clogged drain and leaving it for between two and three hours. After this time, flush the pipe with about four gallons of water and loosen any remaining blockages with a plunger; this should be enough to clear the problem.
The inorganic compounds which are useful as concrete dissolvers generally include inorganic acids such as hydrochloric, phosphoric, hypochlorous and carbonic acid. Salts of these acids and alkalies such as sodium-hydroxide, sodium bicarbonate and ammoniumsulfate are also eifective.

Caustic soda is one of the best chemical drain unblockers to use when unblocking a drain.
Heavy rain can cause blockages to outdoor drains in a few different ways. Firstly, rain can flood the plumbing system, which causes overflows and flooding, which can last for days. Secondly, water forces dirt, leaves and debris into drains, causing blockages.
Drain snakes also called drain rooters or augers, use a long cable with a spiral-shaped head.
The fizzing reaction and gas created may help loosen some small blockages. However, it is not typically strong enough to break down larger clogs or remove hard-to-reach debris. As a result of the above facts, if you have a serious drain clog, using baking soda and vinegar is unlikely to be effective.
If you are connected to a septic tank, and you have a blockage in the drain between the house and your septic tank, your toilet paper will overflow through one of your external gully traps.
Fill a spray bottle using half of the pure white vinegar and top it off with lukewarm water. Shake the contents of your spray bottle for at least 5 minutes in order to thoroughly mix the water and vinegar. Vinegar's acidity helps in dissolving your cement stains, which makes it easier to remove.
Acidic solutions, such as hydrochloric acid or phosphoric acid-based cleaners, can effectively dissolve and remove calcium deposits.
Easily remove concrete from your tools and equipment with Mean Klean 22 oz. Concrete & Mortar Dissolver. The advanced liquid formula dissolves and physically breaks down concrete by attacking the Portland cement, eventually reducing it to mush that is easy to clean off with a hose or pressure sprayer.
The primary way to dissolve plumbing glue or cement is by using solvents. Acetone, commonly found in nail polish removers, can be quite effective.
