Customer Reviews for ZEP 32 oz. Advanced Kitchen Sink Drain Opener

This product did not work at all. Waste of money!!!

Worked great on my kitchen sink . Only has to use one treatment

Awful did not work and customer service for zep money back guarantee never responded or gave my money back I should get a refund on it

Sink is still stopped up

Worked great. It unclogged the drain pipe where I couldn’t get at it with a snake!

It REALLY WORKS not like the other brands I’ve tried!!!!

This product did not work for me to unclog my sink.

It didn’t work at all.

It was expensive so I really hoped it worked. I needed to do the process two times so I needed more.

I was desperate because my sink was stopped up and I was preparing a dinner for 30 people. The first try was unsuccessful but with the second application of the product the water broke through. I would definitely recommend this product. Thanks…

The recommended 10 oz. cleared a major food clog in just a few minutes. I actually have a clear PVC trap so can see flow through it. What was black and opaque became clear and visible. Great job.

Worked the first time! Will buy it again.

Same formula as bathroom sink should work just fine in bathroom sink
