Zep Drain Defense Pipe Build-Up Remover - 64 oz (Case of 8) ZLDC64 - Professional Strength Liquid Pipe Build Up Remover

Got this for my sewer line. It was recommended to me by my plumber. So far very good. Yes I do recommend this product and if you buy the 8 bottles you will save , money wise.Great product leaves a great smell.

Seems to clean out old pipes, and the toilet tanks

This drain cleaner works great! We have some hinky drain line on our kitchen sink that would get plugged and require a clean out at least once a year, a dirty, stinky, laborious task. My wife has used the Drain Defense weekly, we now go about three years between drain line clean outs, that works for me. We did get a quote to fix the drain line, I can buy an lot of Drain Defense for that $5000.

Good stuff

I live in an old neighborhood and plumbing/sewer is always a challenge. I was told a long, long time ago to use this product, and it will Protect your pipes from corrosion. It's simple, and as far as I'm concerned. It works.

keeps the pipe flowing

I tested several of these and warm water against clogged biomatt 30-40 years old. This stuff was the only thing that worked and it literally melted it like a milk shake and left a nice smell. Once a year dump the entire case down the septic lines straight into drain field.

I have a small inn- 13 bathrooms in total. I have been using this product or a version of it for the last 9 years. I use in all drains monthly- I have never had a stopped up sink, bath, or toilet drain. That speaks for itself. I am not affiliated with the company who make it nor have i received a free product to try for a review.
