Customer Reviews for ZEP 1 Gal. Liquid Heat Gel Industrial Drain Opener

Good customer support

Use this product to help keep my drains flowing and clean. Have 3 women in my house with long hair and every so often they clog the drain with their hair.

Cleared the clog in seconds. Great product

It didn't fix the blockage and they haven't responded with the refund.

This product goes beyond my expectations! I tried other products to unstop my sink but this one one is the best. I will always purchase this product in the future. I have highly recommended it to others. It works very quick and that's another good reason this product is highly recommended! This is the third time I have purchased this product and I will continue to purchase it in the future. I have no complaints about this product.

I used this as soon as it arrived and it did not work at all. I’m highly disappointed in the quality of this product and its false advertisement. However, the delivery was fast and efficient.

Worked as stated. Helped resolve the slow sink drain issue.

We’ve purchased this twice, and it performs well and works as expected. We had a problem with the water going down our bathtub very slowly, and this unclogged it without harmful fumes like some others… still wore a mask and gloves, though. Simply poured the required amount down the drain and waited the prescribed time; then turned on hot water for five minutes!

This is the best drain cleaner I've ever used, I've tried other better known drain cleaners with little to no effect, but Zep worked quickly when others didn't. I highly recommend this product

I had to use two applications to achieve the desired result, but, this stuff cleared out my system GREAT!!!

Did not work on clearing main drain poured all of it in let it set overnight, it made no difference. Plumber cleared with power drain machine..

Cleaner did not work. Used as directed, did not clear the clog.

Works fast. No bad odors.

It is a great product!
