Zep Drain Defense Enzymatic Drain Cleaner Powder - 18 Ounces - ZDC16 - Safe for Pipes and Septic Systems, Pack of 1, white

It's easy enough to use. I put a couple teaspoonfuls down each bathtub, bathroom sink and kitchen sink drains. I will wait to see if there's an improvement on the Phorid fly problem. So far, it's been a couple days and I've not been noticing any significant phorid activity. I'm certain it will work because its an Enzyme cleaner designed to remove food and biological debris that build up in drains which attracts the Phorid fly. Enzyme cleaner was specifically recommended.

This is easy to use. Mix one scoop in a solo cup of hot water. Stir. Dump and flush. Leave sit overnight and repeat the next 2 days. It works!!! Theres enough in this container to do my toliet and drains many times over. Very simple with fast results!!! Buy it. You wont regret it. I dont. The powder doesnt smell. The consistency is normal and the value for your money is epic. Zero leakage.

I did not get a scoop in mine which is problematic . I used a very liberal amount the first night , my drains were not clogged though I was worried they were sluggish at times . Gave it a good 8 hours after following the instructions . In the morning I filled up the sinks with stoppers , turned on all the faucets otherwise and took out the stoppers sending a rush of water through the pipes . They all drained very well . So much so I believe there was improvement the first night and enough so the next few days will not be able to perform better . However as instructed this first time through I will repeat for 3 nights in a row . I use ridx monthly and have for years . I had also put down Liquid Plumber before winter each year in my pipes feeling sad I was killing good bacteria in my septic systems . Will use this stuff from now on . Took one star off for no measuring cup and fact you really seem to need to use allot at first way more then they recommend . There is no way I will get 44 applications I will be lucky to get the 3 nights times two systems or 6 heavy applications from the $12 container for the first run . After that I imagine I can use less . If I could get it down to what they recommend I would get almost 2 years out of a container ( 44 uses or / 2 systems 22 months ) making it cheap to use . I was most impressed at how it helped my bath drain . Make sure you have a bucket or somewhere to wash your hands . I have a sump pump on a sink downstairs that just pumps out on the drive but otherwise you would need a bucket of water so you would not rinse your bacteria out of the pipe washing your hands .

Works great on the overflow hole in your bathroom sink, you know the one that emits offensive smells when you catch while bending over to brush your teeth? Well, yeah, that one. But it's rather toxic, so handle with care. I use a thin tubed funnel, and it has to be mixed in a throw away container first, and left overnight. So plan ahead! May have to do it 2x if it's been a neglected hole (oops, that sounds wrong) but trust me, it will be worth it!

We love this product! Our dedicated kitchen sewer line backs up to the point where we have to go into the line to clean it out (gross, smelly, messy). Using this down the drain once a month really helps to keep those cleanouts to 1-2 times a year. If we would remember to use it more often, I am sure we could cut that down further, but we aim for (and sometimes meet) the 1x per month goal! So easy to mix, pour, and let it do its work overnight.

I had a drain fly problem and unsuccessfully tried some suggestions online for cleaning and unclogging the pipes. I eventually read that an enzyme cleaner might be the best and safest solution to tackle the issue. I bought this product and used it for three nights in a row, leaving it in the kitchen drains overnight, covering the drains, and then rinsing them with hot water the next day. I also used it to clean the garbage disposal as instructed. I believe the drain fly problem is solved for now with the help of this product, deep cleaning my kitchen and using some other methods. The problem is my garbage disposal now smells like rotten sawdust from this powder. I have tried just about everything to clean and sanitize the disposal to remove the smell but it won't go away. The smell wasn't there before I used this product. I don't know what to do.

I had an uncomfortable number of drain flies so I got Zep and applied it 3 days running, as instructed. The number of flies was greatly reduced almost immediately but I was still seeing a couple a day. This went on for a few days until they finally disappeared completely. I will be doing a monthly maintenance treatment, as suggested and also be more diligent about cleaning my garbage disposal flap.

I've ordered this 4 times in the past for myself and family. Works great. This is the FIRST TIME EVER I've ordered it, and had it show up unsealed, opened, missing the scoop and HALF EMPTY! What.... did they think I wouldn't NOTICE???? I try to get the issue fixed, and all I get it "return the item and drive to a UPS Store" a hour away. When did they get rid of label pickup? Then spend 15 minutes dealing with a broken AI chatbot, and a failure to return a call, to finally get a human in the chat. This is ridiculous. Apparently Jeff needed the money more than we did. What a complete ripoff.

No amount of cleaners or bleach could get rid of the smell coming from our bathroom drain. Couple doses of this stuff and it’s good as new. Highly recommended!
