      Answer This Question

      A:  This is the only product I have found to remove clogs in my drains (tub/shower, sink).  It removes all odors from the clog and gets your water running. If you have an odor without a clog, I would contact a licensed plumber to get them to see what your problem is.

        A:  I have only used the Zep kitchen drain opener. It worked great to unclog the drain. I can't verify that it eliminates odors.

            ZEP Advanced Tub and Shower Drain Opener worked well and cleared the drain. My drain always slowed while taking a shower and found myself standing in water. It wasn’t a complete blockage just extremely slow. After the water cleared the tub, I poured half a container about 16 oz. down the drain. I waited about 90 minutes then ran the hot water. The difference was impressive as the drain was completely clear. No matter how fast I ran the hot water the drain was fully open and never filled the tub. I observed all the recommended safety precautions. Most important was to wear goggles to protect my eyes from possible splash back. ZEP makes a variety of drain openers each for a specific application.

            The Zep 32oz. Advanced Tub and Shower Drain Opener works wonderfully! The company guarantees that their product will work or it's free, but the gel simply works and is worth the purchase! The gel is designed to work with all types of pipes and even works with septic systems. Because this unclogger is a gel instead of a liquid, it also works in standing water. Instructions are very clear: pour 16 ounces of gel into the drain, wait for the clog to clear, and rinse with hot water. Pouring 16 ounces out of the 32 ounce bottle was the hardest part of the procedure, since there is no clear window into the bottle like other brands. I just had to guess when half of the gel was poured out. After pouring the gel, I waited about 20 minutes before flushing with hot water. No more clogged drain! This product works great!

            Nice product that helped us out with a slow shower drain. What I like: • My daughter's shower has a very slow drain. Long hair, soap, etc. I followed the instructions and this quickly opened up the drained. I’m so happy. I actually tried a different product that helped but did not do nearly as well as this did. • Safe for septic for those of you that have them. • The 32oz bottle has is good for 2 drains and each take about half the bottle. • Easy to use. This stuff is pretty strong so I recommend gloves and safety glasses just in case you get some splash back into your face or on your skin. I recommend.

            Used the 32 oz. Advanced Tub and Shower Drain Opener on two stubborn drains I had. Both of these drains had been slow to drain and I knew it was matter of time before it became worse. After reading the instructions I poured half the container in each drain. I noticed it was really thick so did not splash up. I did notice its meant to clean a clog out not the sides of pipes like some"foaming type". Noticed within 20 minutes that the drain that was more clogged was now cleared. Overall happy with the product. Note, you use half the bottle (16oz) so there is 2 uses.

            It’s a good product and functioning very well.
                unfortunately it did not work at all even i followed the instructions
                  The tub drain hadn't been cleaned in years and was so slow the tub was filling with water. I used this product according to the label directions (there was no standing water in the tub) and with one application the drain is clear and no water is accumulating at my feet. A miracle!
                    Works Great
                    Had a slow tub drain. Snaking did nothing. Normal drain cleaners did nothing. Figured it might be a soap clog/restriction since the pipes were over 30 years old. Decided to try this. First treatment was a vast improvement, second treatment fully cleared the pipe. Amazing stuff!

                      Worked like a charm. Used on a shower drain and it was all good after like a 15 minute wait before hot water and then presto, the water drained just like it should.
