Commercial Drain and Grease Trap Cleaner/Concentrated Enzyme Drain Cleaner/Organic Liquid Bacteria For Plumbing Lines (1-Gallon)

Important for people to know this is not a drain opener but a drain maintainer.

as described

I like this drain cleaner. We use it to keep the main sewer line clean of soap

WE used the whole gallon over a month and thue drain is still clogged, very upset!

Keeps drains running smoothly and odorless. Just 3 caps in all my drains every 2 weeks is all it takes.

Free flowing drains!
