Are bacterial drain cleaners safe for old pipes?
Yes. Bioaugmentation is neutral pH and won't attack cast iron, copper, or PVC. Caustic chemical openers can damage older pipes.
Why it happens
Bacterial drain treatments use beneficial microbes to consume organic waste like grease, soap, and hair. This biological process differs from caustic chemical openers, which use harsh reactions that generate heat and can corrode older metal pipes or damage plastic pipe joints. Because bioaugmentation is a neutral pH process, it cleans lines without harming the pipe material, making it a safe choice for preventive maintenance in buildings with aged plumbing.
What to check
For ongoing maintenance, establish a regular treatment schedule with a bio-enzymatic product, particularly for kitchen and high-use drains. If drains are already slow, determine the cause. Bio-cleaners are effective for organic buildup but won't resolve foreign objects or root intrusion. For complete blockages, mechanical clearing like hydro-jetting is necessary before starting a preventive bio-treatment program.
When to call a professional
Call a professional for recurring backups, which may signal a serious problem in the main sewer lateral like a collapse or root intrusion. A professional should also be engaged immediately if you detect sewer gas odor, as this can indicate a health hazard. They can properly diagnose the underlying cause and determine the correct approach, whether it's mechanical clearing or a line repair.
How Luften handles it
Luften uses bioaugmentation and foam treatments as part of a comprehensive drain maintenance program. We can consolidate drain care with services for grease traps, ejector pits, and trash systems under a single agreement. Our in-house technicians provide documented service visits and can install automated dosing equipment for continuous protection. A site survey can identify all sources of recurring drain issues.
