Plumbers in London

Blocked drains can be a real pain and inconvenience. There are shop bought products which are suitable to use and may just do the trick. If the blockage is really greasy and full of debris, stronger chemicals may be needed which only a plumber can buy. 

Depending on the type of blockage, different approaches can be made. For instance, pour hot water down a blocked drain to try and cleanse remove any substance which is blocking the flow of water. Then, try using a plunger to suck up any loose debris. 

If these methods have no luck, try a drain cleaning product. There are three main types of drain cleaners:

Caustic drain cleaners: is a base which will create a reaction on the substances stuck in the drain and clear the clog. The chemicals inside the product will release heat and easily dissolve grease by making it into a soapy material. The liquid is denser than water therefore is able to reach the blockage through sitting water. 

Oxidizing drain cleaners: contain bleach, peroxides and nitrates. These chemicals cause the material of the blockage to become oxidized by releasing gas and heat to help clear the clog.

Acid drain cleaners: cannot really be bought in shops as they contain high amounts of acid. The liquid will release heat once in the drain which then melts hard grease is stuck. 

When using shop bought products ensure you read the instructions beforehand.
