Best Drain Cleaner – Buyer’s Guide
The best drain cleaner will keep your entire drainage and septic system in top shape for years, and you won’t have as many issues with it.
When it comes to trying to pick out the best drain cleaner, there are a few factors that you have to consider before you settle on one specific product. Doing so will help you narrow down your choices and pick out the best drain cleaner to prevent your drainage system from backing up in your yard and causing your home insurance premium to skyrocket.
- Drain Cleaner Type – Do you want to mix your drain cleaner or do you want it to come pre-mixed and ready to go? Always take a look at the instructions before you buy the best drain cleaner to ensure you don’t pick a product you have trouble using. If you do, it won’t be as effective and it could cause damage to your pipes.
- Blockage Type – The types of blockages you usually have at your home or business play a pivotal role in what the best drain cleaner is for your needs. If you get more stubborn blockages, you’ll need a thicker formula to break it down. Test this by pouring a bit of hot water down the drain. If it sits, you need something stronger. If it doesn’t, you can get away with granulas or a thinner drain cleaner.
- Maintenance – How much do you maintain your drainage system? This matters because it dictates how severe your clogs can be. If you perform monthly maintenance, you most likely won’t have a lot of issues. However, if you’ve skipped your maintenance, you may need a more powerful product to pick up your slack. The clogs can be larger and more stubborn to remove.
- Budget – Your budget will play a role in the best drain cleaner you choose, but it is usually beneficial to spend more upfront for a quality product. If you don’t, you could find yourself spending more money on cheaper products because the first one doesn’t work as well as you hoped it would.
- House Size – How big is you home or business and around how many people use your drainage system? The more people and the larger it is, the more they use it. In turn, you can get more frequent and larger clogs that will need a stronger product to break them down.
- Septic System – Your septic tank and pipes need maintenance and are prone to clogs and breaking down just like your other drains. You should get a product that is safe to use on your septic system as well as your drains.
- Pipe Type – Some drain cleaners are too caustic for PVC or aluminum pipes. Double-check and see which types of pipes you have in your home and make sure your drain cleaner is safe to use with them. If it’s not, it can cause damage.
Drain cleaner can help extend the life of your drainage system, but there are considerations you want to keep in mind when you shop.
How to Use the Best Drain Cleaner Safely
Drain cleaner can be very caustic, and this means that it can very easily burn your skin or cause issues if you get it into your eyes. This is why you want to thoroughly read all of the instructions on your product before you attempt to use it. This is where you’ll see the safety precautions. You have to follow these warnings to ensure you don’t have an accident when you use your drain cleaner. It’ll also improve the best drain cleaner’s effectiveness.
Depending on the type of drain cleaner you get, you may have to wear safety glasses or goggles, gloves, and a face mask. Others require you to be in a well-ventilated area because it can produce fumes when the cleaner combines with water. Also, it may have to sit for a specific number of minutes to be the most effective, and all of this will be on the bottle. It varies from cleaner to cleaner.
Along with everything we talked about above, there are several other things you want to consider when you shop for the best drain cleaner. Using these considerations will help you narrow down your choices. They include but are not limited to:
How much time do you have to sit and wait for your product to work? Maybe you want to really clean your windows and screens in the bathtub, but you only have a few hours. If so, you need a drain cleaner that works quicker than others. Take a look at the recommended time limit on your best drain cleaner. Some are a few minutes, but others can have a recommended time of overnight.
Think about how long you can leave your drain cleaner sit in your sink or tub before you need to use it because this will influence which product you buy.
Natural products that contain non-toxic ingredients usually have fewer fumes than drain cleaners with a heavy chemical content. These chemicals can produce fumes when you mix them to get the product to work or introduce water to them. These fumes can be dangerous to breathe in, so you want to make sure you have great ventilation when you use them. You also may want to use a face mask.
Do you want a gel, liquid, or granular drain cleaner? Gel drain cleaners are nice for stubborn clogs because they sink below the water and get to the clog if you have standing water. Liquid and granular work well on less stubborn clogs, and all three can take different times to work. Consider the amount of maintenance you usually perform on your pipes when you choose a form.
As long as you upkeep your drainage systems, you shouldn’t have any problems finding an effective drain cleaner to keep the water flowing through at top speed.
Figuring out the best drain cleaner is different for everyone because everyone’s needs and situation is very different.
