Caustic soda
Caustic soda is an effective unblocking agent for rainwater drains. However, it should be used with extreme caution as it contains highly corrosive substances. Although it can clear drains, excessive use of caustic soda can lead to harmful effects, including vision impairment and gastrointestinal ulceration. In rare instances, the substance can even be fatal. Therefore, you should always wear protective equipment when using it.
To use caustic soda to unblock a rainwater drainage pipe, mix a teaspoonful with one gallon of water and pour it into the blocked area. Allow this solution to sit for about half an hour, then pour boiling water to flush it away. Alternatively, you can also use baking soda. You can also mix baking soda with washing up liquid or vinegar, and pour it down the drain. Once you have completed these steps, flush the drain using hot water.
Flexible drain rods
To unblock a rainwater drain pipe, you can use drain rods to push the obstruction out. The rods are flexible and can be pushed back and forth in the pipe. The buildup of water pressure will break the blockage, forcing it to flow out. However, you should use care while applying pressure, as it can damage the drain.
Drain rods are a great option for unblocking drains in homes. They are long rods that have a plunger on the tip that can be inserted into the drain pipe. These rods are also ideal for more severe blockages.
External drain unblocker liquid
There are a number of external drain unblocker liquids available to use to clear drains. These are usually available at local stores and can be very effective. One of the best known chemical drain unblockers is caustic soda. It works by reacting with debris and leaving only the particles. It can be used to unclog drains in both indoor and outdoor areas. You should dilute this solution in a large bucket of water before pouring it into your drain.
You can find external drain unblocker liquid in most local stores and supermarkets. Make sure to follow the manufacturer’s instructions, as some drain cleaners have a minimum time limit before they are ready for use.
Chemical drain unblockers
Chemical drain unblockers are an easy solution for clearing blockages in a rainwater drain pipe. However, be aware that they contain chemicals that can damage pipes. Acids used in drain unblockers can dissolve the finish of pipes, weakening them and causing fractures and collapse. To avoid these problems, it is recommended to call a drainage expert. In the UK, there are a number of drainage specialists available.
Over time, everyday products can build up in a drain, causing a blockage. Fluff and hairs can also accumulate, and larger blockages may form without warning.
Using a drain snake
If you’re facing a clog in your rainwater drain pipe, you may want to try using a drain snake. It is a tool that is attached to an electric drill and can help force through the clog. A snake can also reach deep into a drain to reach the clog.
A drain snake can be quite dangerous, so you must take care to use it carefully. You can buy one from a hardware store. The rod should be inserted into the drain and twisted clockwise to dislodge the blockage. When using a drain snake, you must always be careful and follow manufacturer’s instructions. Otherwise, you may risk damaging the pipe.
If you don’t want to use a drain snake, you can always use baking soda and white vinegar to unblock your drain. Then, you need to leave the mixture in the drain for 15 minutes to break up the clog. The cost of unblocking your drain will depend on its size, location and the severity of the blockage. The best way to get the best price is to compare several quotes.
