Can you use this product to unclog toilet?

Asked by: yamia
Unlikely. The general nature of a toilet is using the water weight and pressure itself to flush the bowl. To use this product with that level of water in the plugged area would be a waste. The granules promote a chemical reaction in the pipe equivalent to boiling water (or hotter). To use this product for that purpose, I don't think you would have enough powder to get the effect you wanted. And if you used that level of powder (like a whole bottle for instance), it would be too intense to clear the clog. If your clog is not near the bowl, a plunger is not your solution and only a long snake to clear the line would be.

I have a slow drain problem in my bathtub. Yesterday I used Liquid Plumber and it did not work.

We have taken 2 showers since using Liquid Plumber and still have same problem. Would it be safe today to use the Crystal Heat Drain opener today? Is the Crystal Heat similar to the old Red Devil Lye which is now impossible to get?
Asked by: Claire
This will definitely work. Used it to clear a slow laundry sink.

2 lb. Crystal Heat Drain Opener is rated 3.7 out of 5 by 48.
Rated 1 out of 5 by from Melted pipe Poured it in bathroom sink let sit for 5 minutes and ran water through it for a few minutes after. A couple of days later I realize I had a hole burned through the s-trap and water had just been draining on the towels under the sink. Had a huge mess to clean up.

Rated 4 out of 5 by from Mixed Reviews; Overwelming Smell At Times This one got mixed reviews for me. It is a good product, but I used it twice and got two differing responses from it. It is super easy to use -- just pour a cap full of granules (heaping tablespoon) into the desired drain, after removing as much water as you can from the plug, and then wait for the chemical reaction to begin. Then flush with cold water (it really does get warm/hot). The premise behind the product is that it has a chemical reaction to create heat in the pipe. So much so, that it is equivalent or better to boiling hot water being introduced into the line. This is supposed to dissolve gunk in the pipe and make it flow better. The cold water at the end is to bring down the heat in the pipe so that nothing bad happens (melting, pinhole leaks, etc). When I did this as part of general maintenance on my kitchen sink, I did not find that it did much. But then again, it was not truly plugged. I used it more for a grime and residue cleaner. I followed the directions and then flushed with water. Everything worked normally. Which was great. I did this more to clear some of the food waste from the dishwasher line that is attached to the plumbing. I also did it to clear out some the smell that builds up in the disposal. I liked it. And it did not hurt the pipes. I did not see any of the chemical reaction to make it hot either. No fizzing. No smell. No nothing. So I really don't know if it worked for that. Now, moving on to a bath tub that is used, it did get a chemical reaction. And it smelled so much I had to open the window, shut the door and leave the room for a bit. Then upon return, I flushed the tub with cold water and the drain did seem to clear better - not perfect, but dramatically better. So I know it did something. But the smell was a little too much. I don't know exactly what it was working on other than hair and soap scum, but it was intense. It did appear to clear the drain though. While it says it is good for all pipes, I would be hesitant in putting it into anything older (like over 20 year or something). It is good for PVC and for metal piping, but given the nature of chemical reactions and not being able to physically see into your walls, I would not recommend it for that purpose. If however, you have new plumbing or can get to the effected u-joint, go for it.

Rated 5 out of 5 by from Cleared a clog nothing else could! I had a nasty clog in a pipe in my basement that of course drained my laundry tub and kitchen sink out to the rest of the drains in the house. We have been trying everything for almost 2 months and nothing worked, not even a 25' snake. I was just about to give in and call a plumber (sick of doing dishes in the tub and laundry at a family member's house) when we tried Crystal Heat. It smoked and fizzed and took multiple applications to get to the clog so far down the pipe, but it worked! We were shocked to run water this morning to check and not have it back up!

Rated 5 out of 5 by from The best way to clear a drain. I'm going back a few years, but there was a product called Red Devil Lye that was available at the grocery store. It was very inexpensive and did a great job. Well, I heard that Lye (Sodium Hydroxide NaOH), is used to make illegal drugs, so Red Devil Lye is no longer on grocers shelves. I was glad to find Crystal Heat at Home Depot. I read the label and yes, this is NaOH. My tenant had a clogged drain, so I did my usual routine. First, I open the window. If possible, I run hot water down the drain (if it's slow) and get the pipes nice and hot. I then pour the drain cleaner in - about a couple teaspoons, but I don't measure. I then leave the room and close the door. 10-15 minutes later, I come back in and listen to the drain. If it's still hissing and smoking, I leave for another 10-15 minutes. When there is no more noise, I run hot water down the drain and see if it cleared. If it's still clogged, I repeat. Normally, it takes about 2-3 tries and I usually do one extra to make sure the drains are really clean. Note that the directions on the container say to run cold water, not hot. If you use my method, NEVER look down the drain and after dumping the cleaner down the drain, get out of the room. You can also leave a plastic margarine tub cover over the drain. This is caustic chemicals, so you need to use extreme caution.
