Using Zep has saved us a large amount of money.

Before we began using Zep Drain Defense we were continually paying plumbers to unclog our home drain lines with commercial level devices. We heard about Zep from a plumber, and began using it years ago. We have not had to use a plumber since then. A product that truly works.

Great for line build up!

I use it at a high volume restaurant, and have not had a clog since. We fry a lot and it keeps the grease from building in the lines.
