There was a problem filtering reviews right now. Please try again later.
Snaking does not get rid of anything, it just moves the gunk around. My house is 50 years old and I assume the pipes were filled with grease and lint combo that had gotten to a point where the pipes should have been replaced. I tried everything over the last few months. All the liquid plumbers, worthless enzymes etc etc. Literally wasted a few hundred dollars on all that. Nothing worked.
The problem got so bad that water was now backing up into the washer drain pipe as well. I had to stand next to the washer during the drain cycle and stop the draining then start it again.
I was almost ready to give up. I kept searching on Amazon and this Lye stuff showed up in the search result. I never heard of it before. I bought two of these and will now explain what my procedure was:
Put on gloves and eye protection. Put about half of one container into a bucket. Added about 6 cups of cold water. Used old wooden chop sticks to slowly mix it. It will get really warm. Poured it slowly into the KITCHEN sink. Did the same thing again with the rest of container one and poured it into the WASHER drain pipe.
I did not allow any water after that to get into the pipes for the whole night. I pre-poured water into buckets for washing hands and even late night pee runs were done in a bucket pre filled with water.
I did this process for two nights in a row using both containers of this lye I bought. The next day I filled the kitchen sink with VERY hot water and dish soap. Let it drain. This was done each day so a total of twice.
The problem stated has been completely solved. I can run the washing on full load and run the kitchen faucet at the same time as the washer drain cycle and there was no back-up of water. UNBELIEVABLE!!
This was my last chance, if this didn't work then I would probably spend thousands to just have those outgoing pipes replaced. Thanks to the people who make this product.
After first trying a drum auger I found with no luck, I decided lye might be the solution and used it as part of a trifecta of clog removal solutions. The clog was very obviously deep in my wall instead of being immediately accessible and I'm just a typical 30-year-old with no knowledge of plumbing really...
For me, there was no explosion or craziness, but I did don a mask and a full-length coat just in case something crazy did happen (and you should as well if you buy this). After the first pass through with the lye, I didn't notice any change, so I decided to do it again, this time mixing it in a plastic container with the hot water in advance and then pouring it down the drain all together (Do not do this unless you have the gloves and the protective glasses!) and letting it sit for a few hours.
When I poured hot water into the sink after letting the lye sit for about 6 hours, it immediately backfilled and I was really bummed out, but I decided to actually *boil* some hot water and pass that through the pipes. A lot of people say not to do this if your sink has a PVC pipe in it but I passed about 10 quarts total of boiling water and started seeing a bit of an improvement at that point. I finished everything up by allowing the sink to fill some and using a plunger on the drain. At this point, all sorts of disgusting black stuff was coming up... but the sink finally returned to a somewhat functional state.
I'm sure this clog pre-dated me living in my house and unclogging it felt like a serious effort. In retrospect, I would have probably just paid for a plumber to come out because it ended up eating my entire Sunday. On the other hand, I would recommend the lye as a PREVENTATIVE maintenance tool for stubborn and clog-prone sinks. Personally, I think the plunger technique was the most effective, but this lye definitely jumpstarted the process.
I'm guessing if you don't live in a super old house, this stuff will do the job much more easily... in which case, you should buy this instead of Drano because it's way cheaper, but you should also try not to be a Darwin Award winner and maintain a healthy fear of lye, because the stuff is really dangerous to play around with if you're not taking all the precautions.
