It’s common for drains and sewers to block from time to time
Drains and sewers can easily get blocked by grease or food. There are a range of things that can be used to clean and unblock them.
Chemical drain cleaners
These are available from most supermarkets and can be liquid or solid. They’re very easy to use and normally just need putting straight down your sink or drain. They’ll usually react with and break down your blockage fairly quickly.
Enzymatic drain cleaners
These contain bacteria cultures and react with sewer residue to help clear slow-moving drains. They’re used for general maintenance rather than fully clearing the blockage because they rely on liquid flowing through the pipes to work.
Air burst drain cleaners
These use accelerated gas to break up drain and sewer blockages. It’s normally carbon dioxide but could be normal air or other gases. They have a limited range and should always be used with hand and eye protection.
These use high pressured water to clean pipes and drains. They can remove obstructions throughout the length of a pipe and prevent the build-up of future blockages. They can be difficult to use so are best left to the professionals.
Handheld drain augers
These use a cable and rotating drum to clear blockages within 8 metres of the drain opening. They should always be used with hand and eye protection and, although readily available, are usually best used by professionals.
Electric drain cleaners
Electric drain cleaners are, in effect, longer electric versions of the handheld auger. They can reach lengths of approximately 40 metres and are generally designed for professional use.
