Top Solutions: Best Drain Cleaner for Old Pipes

Share —

Old piping systems are more vulnerable to drain clogs than new ones. With years of accumulated soap scum, grease, hair, and other debris, your old pipes may not be as clear as they once were. This can result in slower drain times, standing water, and even backups. Luckily, a good drain cleaner can help restore your old pipes to their former glory, without causing damage. In this blog post, we will be looking at the best drain cleaner for old pipes.

Effective Drain Cleaners For Old Pipes

When it comes to maintaining old pipes and ensuring they remain functional, the proper drain cleaner is essential. There are several types on the market, each designed for a specific task, but not all these drain cleaners are suitable for old pipes. Therefore, it's important to make a cautious and well-informed decision.

1. Enzymatic Drain Cleaners

These are the most gentle yet effective types of drain cleaners. They use enzymes or bacteria that break down the clog moving through old pipes without causing any harm. These types of cleaners require some time to work effectively, but they offer long-lasting results:

  • Green Gobbler's Enzyme Drain Cleaner
  • Biokleen Drain Gel

2. Acidic Drain Cleaners

Acidic drain cleaners are powerful and can handle tough clogs. However, they must be used with caution – not frequently and in the required quantity only as they can damage old pipes:

  • Instant Power Hair and Grease Drain Cleaner
  • Professor Amos' Superfast Drain Cleaner

3. Alkaline Drain Cleaners

Alkaline drain cleaners are also an effective choice. These types of cleaners predominantly use lye (sodium hydroxide) in their composition and are effective on organic blockages:

  • Drano Max Gel Clog Remover
  • Xion Lab Fast-Acting Drain Opener

Choosing the Best Drain Cleaner for Old Pipes

Choosing the right drain cleaner for your old pipes involves considering several factors. Narrow down the choices by following these tips:

Know Your Pipe Material

Understanding what material your pipes are made of can help you avoid causing further damage. For instance, metal pipes are more prone to corrosion from acid-based cleaners. On the other hand, PVC pipes can withstand the chemicals better.

Identify The Blockage

Know what is clogging your pipes. Grease and soap blockages are best handled by alkaline drain cleaners, while hair and food particles break down easier with acidic drain cleaners.

Environmental Impact

If environmental consciousness is important to you, consider opting for enzymatic cleaners. They're non-toxic, biodegradable, and pose no harm to the natural world.

Caring for Your Old Pipes 

While a good drain cleaner can resolve existing issues, it’s also essential to prevent clogs from happening. Regular pipe maintenance and understanding what should and should not go down the drain can reduce the likelihood of clogs.

Regular Maintenance

It's recommended to regularly use enzymatic cleaners, even if there's no existing clog. Known as maintenance-based cleaners, these keep the drains clean and eliminate odors.

Know What’s Going Down Your Drain

Avoid throwing large food particles, coffee grounds, hair, or non-degradable items down the drain. These items can accumulate over time, leading to significant clogs that may require professional assistance to clear.

Use a Drain Guard

Installing a drain guard in your sink and bathroom drains can prevent unwanted material from getting into your pipes.

Having old pipes doesn't necessarily mean frequent clogs or blockages. With proper care and maintenance, coupled with the right drain cleaner, you can keep your old pipes functioning almost as good as new.

What makes a drain cleaner suitable for old pipes?

If your pipes are already significantly corroded or damaged, using a drain cleaner may not be the best solution. It may be sensible to consult with a professional plumber to evaluate the condition of your pipes and advise on the best course of action.
