There are a few things that are important to keep in mind while you’re shopping for a drain opener.

These include the effectiveness with regard to what materials they dissolve and what kinds of pipes they work well on and the pricing.


One of the key things to keep in mind is what kind of clog you need to work on and where it’s located. Not all drain openers are going to work equally on the same kinds of clogs.

Some are better equipped to deal with hair while others may be more apt to working on a wider range of materials.

You’ll also need to pay attention to where the drain opener can be used. Many aren’t recommended for use in septic systems because they may not be environmentally safe, or safe for the plumbing in that area.

This can be less of a concern for those who are dealing with clogs in their sink or bath tub drain.


Just about everyone has a budget, and it can be tricky to find a suitable drain-opening product for a decent price. Not many people think to purchase drain cleaners before a clog has actually started causing them problems. Luckily, there are a decent range of solutions at different prices.

It’s important that you find something that will work the best for the lowest price you’re willing to pay, which is why many people turn away from name brands or look into using lye rather than liquid mixtures.

For these situations, it’s especially important that you keep safety in mind as well. These products are made to dissolve well and therefore can be rough on skin. Regardless of which you choose, make sure you wear gloves and potentially even suitable eye protection to remain safe.

Drain Opener FAQs

What do I do about standing water?

If you want to try taking some of the water out before trying to unclog the drain, that can be a good idea. However, most of these products are made to be able to work even in the presence of water so that it can drain automatically once the drain opening product has done its job.

In order to make sure you won’t have any problems, look for a cleaner that specifically states that it can sink through standing water to get to the clog.

Are drain openers safe for all pipes?

Most common drain openers can be used on just about all kinds of pipes, but it’s important to double check the option you choose so that you don’t cause any problems accidentally. There are cases in which some drain openers cannot be used in septic systems or with rubber pipes.

Typically, metal and PVC pipes can handle many kinds of drain cleaners without a problem but if you have something aside from those that need a clog cleaned out then make sure the product you choose specifically states that it will work for your pipes.

What if the drain cleaner doesn’t work?

If a drain cleaner doesn’t work, it may be worthwhile to try a different kind. For example, if you’ve tried Liquid-Plumr then you may want to try something more powerful, such as pure lye. Otherwise, you may find that you need to remove the clog manually.

There are other kinds of products out there that can help to clear up your drain, including drain snakes. Inexpensive versions of these devices can be purchased online or in a store. Typically, you can run the snake into the drain and then pull it out, along with the source of the clog.

What other steps can I take?

Drain snakes that you can purchase in the store often work best on hair, and drain openers tend to be more successful if the clog isn’t very deep in the pipe. If the clog seems to be deeper than that or is made from something more difficult to remove, then it may be time to call in a professional.

For the most part, one of the aforementioned options will work perfectly well in getting rid of your clog. You’ll just have to be patient and allow the substance plenty of time to work and use it more than once if needed.

When should I call in a professional?

Buying products and finding out that they aren’t working can be very frustrating, but it’s worthwhile to try them out just in case they can help you to avoid having to pay more to get the problem fixed. However, once you’ve tried two or three openers or devices with no problem, calling in a plumber can be a good idea.

A plumber can be better equipped to work on deeper clogs or those that are made from tougher materials. In these kinds of cases, a professional can be well-worth the cost.


Overall, the drain openers in this list will be able to help you resolve clogs quickly, without having to spend the money on a plumber for something simple like hair or food.

They work in a wide variety of locations including sinks, bath tubs and even toilets.

At the top of the list here is the Drano Max Clog Remover. It’s a fantastic product and a common household name for a reason.

This product is designed to work effectively on a number of materials in several different kinds of drains, so you’ll be able to get rid of clogs with plenty of time to spare.
