So many things go down your drains every day. Dirty dishwater, your hair when you take a shower, old food off of scraped plates. The slime from your soap builds up and creates a breeding ground for all sorts of viruses and bacteria. It’s also always dark and damp so it’s a great home for mold and fungi as well.

You also run the potential of clogs from all the gunk that goes down your drains. That’s why finding the right drain cleaner is crucial to maintaining your drains and overall health of your plumbing system.

Drain cleaners are a great way to kill the bacteria that lingers behind too so making sure that you have the best drain cleaner is essential to avoid all these nasty and unwanted problems.

Benefits of Drain Cleaning

Clogs, germs, slime, and odor are some of the things you are trying to combat when you clean your drains. But maintaining them also ensures that your plumbing is in great working order too.

Odor

The stuff that gets trapped in your drain also contributes to continuing build-up and with nowhere to go, just sits there and rots. This is what creates the odor that comes up from your drains—especially in the kitchen. Rotting food particles and other things left behind can also attract fruit flies. Using a cleaner eliminates the rotting matter and keeps the bugs away.

Proper Draining

Drain cleaners will clear the path for the water to go through the pipes effectively. This prevents your toilet from overflowing for no reason, water from pooling up in your kitchen sink and shower, and keeps everything flowing as needed.

Prevents Leaks

Drain cleaner eliminates the chemical deposits that can cause corrosion on your pipes. This corrosion can lead to leaks and an overall breakdown of your plumbing system, which can further cause potential damage to your home. Your water pressure can most things down, but sometimes water alone can’t break down these deposits and drain cleaner works as the aid that can.

Keeps Cost Low

This goes hand in hand with preventing leaks. When you maintain your plumbing system with drain cleaners, you are avoiding the future catastrophe of pipe leaks and bursts. This also means fewer visits from the plumber to snake your system and clean it themselves. Liquid drain cleaners can maintain your lines just as well as a plumber and if they do need to come out, they will be able to diagnose a real problem since they won’t have to clear the pipes to get to it.
