Getting rid of black gunk in drain pipes.?

Question

I have this black gunk that collects in my drain pipes and clogs it up. I have tried enzymes, Draino, and baking soda with white vinegar but nothing seems to really get rid of it. Is there something out there that I can try to see if it can get rid of it?

I have tried using acids, sulfuric acid, but the smell of rotten eggs fill the house for hours. I have been told that the black gunk is soap residues.

Answer 1

You can have the drain line flushed out by a professional or go to your nearest home depot or lowes. ask for a drain opener. I'm not sure of the correct term but it attaches to the end of your garden hose. before you turn the water on insert it into the open drain line. have someone hold the end while you turn the water on. the pulsating action will flush out the line.Once the drain line is cleaned out pour vinegar down the drain. let it sit for a while before using. Once a week there after pour a cup of vinegar down the drain in the same fashion.

Answer 2

Be careful when using chemicals in drain pipes, particularly if you don't know what your pipes are made of; acids and chemicals can do serious damage to PVC pipe.

Though there will be others with numerous suggestions about fixing the problem, if it a really bad problem, hire a professional to inspect your pipes. Stop-gap techniques may only makes the problem worse.

I usually hire a good plumber to inspect the drainage system prior to submitting a contract bid on any major renovation project. It is well worth the expense. Provide him/her with a good idea of the material dispensed though the pipes on a fairly regular basis.

Answer 3

The black gunk is probably mold try using household bleach. Acids have little or no effect on mold.

Answer 4

try Liquid Fire. it's an acid.
