Battle of the explosive clog busters video

Tremble before the awesome power of the mighty KD100 CO2-powered pipe unclogger. This is the latest clog buster from the makers of the Kleer Drain, which I reviewed last year.

I saw your new post on boingboing about Kleer Drain's new product and it reminded me to email you; over the weekend, I picked up the Kleer Drain at Home Depot, remembering your positive review from a year or two ago. I used it on my master bathroom sink which has been draining slowly for months, after reading all of the instructions. Much to my dismay, the sink in my guest bathroom in the hall must have been affected by the force of the Kleer Drain, as not only was I and the master bathroom now covered with the contents of the sink and drain, my guest bathroom sink had spewn water and drain much all over the second bathroom. Now, the sink is 100% clogged and the water level hasn't gone down at all since the weekend, and I'm waiting on a plumber to come fix the problem.

I guess this experience goes to show that sometimes, no matter how smart it may sound to use explosive force on your home plumbing, it's best to leave the job to a professional.

Be careful with the new Kleer Drain unit -- I'll let you review that one before I go buy it.

Reader comment: Jason Gill says in a followup:

I had a plumber come and fix the clog. He reported to me that the master bathroom sink and the guest bathroom sink were actually connected together (ie, sharing the same drain exactly like a his-and-hers sink would be) despite the fact that they are in physically separate bathrooms. Unfortunately, there was no way for me to know this, but the house is quite old and the plumbing was apparently poorly designed. Why the Kleer Drain actually exacerbated the clog still remains a mystery, but I suspect that the fact that the two sinks are connected resulted in some sort of loss of suction or pressure.

That being said, I don't think that the Kleer Drain is a bad product -- I'm sure if I had more "standard" plumbing, I wouldn't have had any issues at all. You may want to consider adding a warning regarding plugging other sinks in older houses (much like the warning to put a rag in the other side of a his-and-hers sink), and it would be nice if you offered some sort of money back guarantee as there are no refunds for the product after use from Home Depot.

Jason, I'm glad to hear you got down to the root of the problem. I never heard of this issue before with Kleer Drain so it is a concern for users who have similar situations. Bad piping design is an unknown factor, especially for those of us who aren't plumbing experts.

Thanks to your old BB recommendation i got one of those CO2 powered clog busters today... worked like a dream (on a toilet... ick) -- just to let you know they now ship with a "splash guard" which is a thin piece of plastic wrap with a hole in it. didn't really help... the bathroom was pretty nasty afterwards... but the drain is flowing nicely.
