my parent's house is old and the kitchen sink clogs every now and then, we have been consistently using drano on a regular basis, clog doesn't happen now. very happy with the product. good price too

I always seem to clog my bathtub and bathroom sink. This gel does a good job unclogging the pipes. You have to use half a bottle per clog, so the product only lasts 2 uses. You wait about 15 mins and then rinse with water and clog is gone!
