Septic System Safe Drain Cleaner

Septic tank systems are something we don’t like to think about and, usually, don’t until there is a problem. A septic tank handles all of the wastewater from homes that are not connected to a public sewer system. The key to maintaining a healthy septic system is to understand how the system works and then follow practices in the household products you use to keep it healthy.

More than21 million households, or 25% of households, in the United States use septic systems as the means of water and sewage disposal — not a public sewer — to trap and filter their toilet waste. According to

the Texas Commission on Environmental Quality, approximately20% of the new homes built in Texascome with an On-Site Sewage Facility (OSSF), commonly called a “septic system.” The sudden increase of new housing in suburban and rural areas means that more Texas households depend on an OSSF for treatment and disposal of domestic sewage.

How to tell if a drain cleaner is actually septic safe

Many people don’t realize that the majority of drain unblocking products found in supermarkets and hardware stores are harsh chemical based and are one of the worst things you can pour down your drains.

They will likely help with clearing drains, but so will a litre of strong acid. We do not recommend you do either, especially if you’re on septic. These harsh chemicals are the main cause of wastewater system odors, blockages and failure.

There are a number of off-the-shelf drain cleaners that claim to be septic safe, which actually aren’t. What they mean by septic safe is that they won’t damage your physical system, but the chemicals they contain will still kill the beneficial bacteria within your system and prevent it from functioning as intended.

Drain cleaners you should avoid

When choosing a product to clear your drains, you should avoid using products that contain any of the following:

  • Lye (sodium hydroxide)
  • Caustic potash (e.g. potassium hydroxide)
  • Bleach (e.g. sodium hypochlorite)
  • Peroxides (e.g. hydrogen peroxide)
  • Nitrates (e.g. sodium nitrate)
  • Sulfuric acid or hydrochloric acid (not commonly sold in stores)

Septic Safe Drain Cleaners

M 77Label

After much research and recommendations from Sewage Engineers, the local plumbing professionals at Justice Plumbing in Granbury, TX recommend and use MARC 77 Microzyme II as our preferred, septic safe drain cleaner and wastewater treatment.

Here are 5 features and benefits of using MARC Microzyme II:

  1. Use of MARC Microzyme II will open up drain lines and keep them free flowing. It will liquefy materials in grease traps and septic tanks. In sewer treatment plants it will reduce the volume of solids, the B.O.D. and the suspended solids. In lagoons it will reduce sludge accumulation, improve clarification, and control odors.
  2. MARC 77 Micro-Zyme Natural Bacteria and Free Enzymes contains natural, specially formulated strains of aerobic and anaerobic bacteria and free enzymes in a patented formula for quick action.
  3. MARC MICRO-ZYME is a unique combination of nonpathogenic natural aerobic and anaerobic bacteria plus free enzymes and emulsifiers for fast action against all types of organic wastes. It quickly breaks down protein, fat, grease, starch, carbohydrate and cellulose materials, It eliminates undesirable odors, as well as having its own pleasant fragrance.
  4. MARC MICROZYME II drain cleaner and waste water treatment will not attack metals or plastics. It is noncorrosive and nonflammable.
  5. The free enzymes in MARC 77 Microzyme II allow the product to go to work immediately, while the bacteria become established and multiply for long term performance. The time lapse comparison video below visualizes this claim.
