There are two main types of toilet blockage: a slow-drainer and a no-drainer.
These are pretty self-explanatory, a slow-drainer is a partially clogged toilet that will still allow water to drain, albeit slowly, while a no-drainer is completely stopped and will have no water movement in the bowl.
For a slow-drainer, simpler solutions like a plunger or a drain opener will probably do the job, while a no-drainer will require a tougher solution, and may even require you to down tools and call in a professional.
What different solutions are available?
Liquid drain openers similar to the ones you would use kitchen sinks and showers are a handy option for less serious clogs. They come in two standard types: chemical and enzymatic. Chemical drain openers use harsh acids and other ingredients to break down tough clogs. However, it’s not advised to use chemical drain openers on toilets for a number of reasons: if the toilet overflows, harsh chemicals and vapours can spill dangerously; similarly, you can’t plunge with a chemical drain cleaner, as it could create dangerous splashback; finally, the harshness of chemical drain cleaners can damage both porcelain and PVC piping. An enzymatic drain cleaner, which uses natural bacteria and enzymes to break down material, is a safer and more reliable option for toilet clogs.
Plungers are a stalwart option for clearing toilet clogs. Plungers create a seal in your toilet piping and work by creating air and water pressure, which works to push through the material clogging your toilet.
Toilet augers and drain snakes are devices which consist of a rotating handle and a long, flexible, coiled cable. The cable is lowered down into the drain, and once it reaches the blockages, the handle at the top lets you rotate the head of the auger, which disturbs the blockage. A toilet auger can be useful when dealing with a no-drainer, as it can reach down far into the piping and break down or bore a hole in a blockage, allowing it to be plunged or for water movement to resume.
A drain pump works similarly to a plunger, creating a seal over a pipe opening and using air pressure to clear clogs. The difference is these devices is that a drain pump uses a pumping mechanism to push in air from the outside, and can often create greater pressure levels than a standard plunger.
Toilet pods are a drain clearing solution designed for maintenance and prevention, rather than unblocking. Usually used weekly or monthly, they work by breaking down small build-ups and chokepoints before they have time to form full clogs or blockages.
How much will I need to spend?
A high quality drain opener can cost anywhere from around £8 to £20, with solid plungers and mid-range drain pumps costing roughly the same. Higher powered solutions such as toilet augers and high-end drain pumps can cost from £30 up to £100+. This may sound expensive, but for houses with problem pipes, having a strong, reusable septic clearing solution can work out to be more economical than paying for repeat plumber visits.
