# Is Liquid-Plumr Clog Destroyer & Hair Clog Eliminator (Sodium Hypochlorite / Lye) Safe for Septic Tanks?

Liquid-Plumr utilizes high concentrations of sodium hypochlorite (chlorine bleach), sodium hydroxide (caustic lye), and sodium silicate to dissolve hair, grease, and soap scum via intense chemical burn. Discharging full bottles of Liquid-Plumr into your plumbing sends an intense caustic biocide shock into your septic tank, destroying digestive bacteria and threatening drain field absorption.

## Official Wastewater Verdict on Liquid-Plumr Clog Destroyer & Hair Clog Eliminator (Sodium Hypochlorite / Lye)

High Concentrations of Sodium Hydroxide (Lye) & Bleach Destroy Septic Biofilm

- Status: DANGEROUS
- Microbial Rule: Strictly avoid in septic systems. Never pour into toilets or use when a septic system is present.
- Primary Risk: Causes severe chemical burns to eyes/skin; corrodes metal pipes and tank fittings; kills septic bacterial colonies; creates hazardous chlorine gas if mixed with ammonia or toilet cleaners.
- Safe Alternative: Mechanical drain snakes, Green Gobbler Enzymatic Opener, or Bio-Clean.

## Biological & Chemical Impact on Septic Bacteria

Extremely toxic to anaerobic digestion. Severe chemical burns kill biological biofilm, turning healthy digesting sludge into dead stagnant organic solids.

Causes severe chemical burns to eyes/skin; corrodes metal pipes and tank fittings; kills septic bacterial colonies; creates hazardous chlorine gas if mixed with ammonia or toilet cleaners.

Strictly avoid in septic systems. Never pour into toilets or use when a septic system is present.

## Frequently Asked Questions About Liquid-Plumr Clog Destroyer & Hair Clog Eliminator (Sodium Hypochlorite / Lye)

### Can I use Liquid-Plumr if I have a septic tank?

No. Liquid-Plumr contains concentrated sodium hydroxide (lye) and bleach, which kills the beneficial bacteria that digest solids in your septic tank.

### What should I do if I already poured Liquid-Plumr down my drain?

Flush the drain with plenty of cold water to dilute the chemical, avoid using other harsh cleaners for several weeks, and add a live bacterial reinoculant like Bio-Clean.
