## Questions & Answers

**Q: When I snaked the ub drain it brought back hair clogs that looked like steel wool, with this remove/destroy hair clogs? what is the shelf life**
A: I agree with the two responses below. Drain Care will not open a clog drain. But it will dissolve grease & other organic material. It will over a very long time dissolve hair. But if the hair has nothing to catch on it should hopefully move thru your pipes. Our drian pipes were very slow draining when we brought the house we live in now, but after using Drain Care, they have been working great. I do treat my drains about twice a year. And Drain Care has a shelf life of about 2 to 4 years. If you get this product just make sure that you follow the directions, & you won't be sorry on how well it works.

**Q: does this work in toilets?**
A: Yes, it works fantastic. I used to have issues with the toilets in my previous house & once I started using this. Bye, bye problems. 
I used it once a month and alternated between them from month to month

**Q: How many treatments in this 18oz. container?**
A: There is a scoop inside the container that is marked 25.0 cc.  The instructions say to use one scoop as directed for 3 consecutive days.  -  I would guess that you will get 15 + treatments per container.

**Q: No scoop.  How much do you use for a drain in volume measurement, i.e. Tspn or tspn?**
A: Thank you for your inquiry. The scoop may settle in the powder during shipping. Two table spoons is the equivalent of one scoop. Mix 2 tablespoons in 16 ounces of warm water. Pour the mixture into the drain and wait 6 hours. Use the Zep Drain Care  Build-up Remover for 3 consecutive days to clean the pipes, then once a month for maintenance.

We appreciate your business and opportunity to service you.

### ⭐⭐⭐⭐ It's a job to eliminate drain flies.
*by S***L on July 17, 2024*

I'm writing this review in order to maybe help someone else that has a drain fly problem. I first saw 1-2 drain flies on my tile shower wall. I first started making my own baking soda/salt/vinegar solution and pouring down the drains. I did A LOT of cleaning of the sink and shower pipes. And, I unscrewed and cleaned out the U-pipes under the sinks. I was still seeing a few flies in the bathroom. Secondly, I tried In Vade Bio Drain cleaner (thick gel) from Amazon. Thirdly, I tried ZEP Liquid Heat Gel Industrial Drain Opener (thick gel) from Wal-Mart. Fourthly, I used Zep Drain Defense Pipe Build-Up Remover Power. This one is the best value because you mix only a small scoop with a pint of water. (I do deduct one star because of the packaging. The canister came in a brown flat paper bag like envelope. When I opened the envelope up, powder had spilled out in the bag. When I got that mess cleaned up, I discovered that the scoop was at the bottom of the canister. Other reviewers have also written this. If the canister had a thin plastic seal on the top, it wouldn't spill out during shipping even if the screw-on cap came off. That's just a suggestion for the company.) This product says - "Made in the USA". I think the two (2) Zep products were good ones. After thorough investigation of the tiled shower, which I had stopped using while fly killing, I found dead drain fly larvae around the cracked grout where the grout flooring meets the tile wall of the shower. The flies were breeding in the shower pan. I have had a fan running in the shower 4 days now. I haven't seen any drain flies in 2 days now. I ordered Tekko Trio Foam from Amazon, and that came in today. I've now sprayed that in the crack line of the grout all the way around the shower. During this whole 10 day process, I've kept the drain openings covered when not in use. UPDATE: Flies were still not completely eliminated after using multiple products, so I hired a carpenter to tear out the whole shower floor & about 4 inches up the shower wall and start from scratch to replace the shower floor. Whenever the carpenter tore out the tile on the lower 4 inches of the shower bench, 8-9 flies swarmed out. He said it looked like the drain flies had made a little cave under the shower bench. It has been a long process tearing out the shower floor and replacing it. My advice to anyone with drain flies in a tile shower is to keep going further to find the source of the moisture and fix it. Then, you will have no more flies.
