Drain Cleaner for Toilet – Buying Guide
Before you go out and buy any old toilet unclogger chemical, there are a few things which you should know first. Let’s go over some tips, advice, and info, so you know exactly what to look for when making a purchase.
Toilet Enzyme Drain Cleaner vs Chemicals
One thing that you should definitely be aware of is the difference between some sort of enzyme waste removal product for toilets and ones that contain harsh chemicals. Now, there is no denying the fact that the strong chemicals will do a good job at breaking down all sorts of waste.
However, the problem with harsh chemicals is that they are not safe for the environment, they are not eco-friendly, and they may be highly toxic too. That said, they do tend to work well.
On the other hand, enzymatic drain cleaners for toilets use special enzymes and bacteria to break down waste and clogs.
These do not always work as fast or as well as the harsh chemicals, but the top of the line products do still get the job done. The clear advantage here is of course that you don’t have to worry about killing the world around you.
How to Unclog a Toilet
Clogged toilets are no fun of course, but before you resort to blowing hundreds of dollars on a plumber, there are some things you can do at home to unclog your toilet. Let’s go through a step by step tutorial on how to unclog your toilet without bringing a costly professional into the mix.
- Try using a good old toilet plunger. The air pressure created by a toilet plunger is often enough to unclog toilets.
- If the plunger does not work, try boiling a gallon of water and pouring the boiling water straight down the toilet. This should help to unclog the drain or at least to loosen things up.
- If the boiling water still does not work, you may want to resort to a chemical or enzymatic toilet unclogging product. If you do this, be sure to follow the instructions on the specific product.
- If at this point your toilet is still clogged, you might want to invest a few dollars into a toilet snake or a toilet auger. This is the tool which a plumber uses to unclog toilets.
- If you still have not managed to unclog the drain, it is time to call a plumber.
Safety Tips
- If using harsh chemicals, wear googles and gloves.
- Some products may require you to wear a respirator.
- Always ensure that the product at hand is safe for toilets.
- Always read and follow all instructions as outlined on your specific toilet unclogging product.
