How long do I leave Liquid Plumr in the sink before I run water in it?

Question

I forgot to look b4 I threw out the bottle & took out the recycle-

Answer 1

45 min should be enough. If the water wasnt going down in the first place when it does go down the blockage should be cleared and you can run the water.

Answer 2

don't use that ever again...you can put baking soda in the drain...as mush as possible...really pack it, then slowly pour vinegar into the drain until it runs clean..[no more foam] do this 2 or3xs a year and you will not have to use that poison again.

Answer 3

You leave it overnight. In the morning flush with hot water, and that should do the trick.
