    Yes, this product is formulated to work effectively on slow drains. For particularly stubborn clogs, we recommend using Liquid-Plumr® Urgent Clear®.

    For best results, we recommend using 1/2 of our 32-ounce bottle or 1/5 of our 80-ounce bottle for every clog problem.

  • Can I use this product in a drain that contains standing water?

    Yes. This product is designed to pour through standing water. However, it is formulated to work most effectively on slow flowing drains. Therefore, for particularly stubborn clogs that cause standing water in drains, we recommend using Liquid-Plumr® Urgent Clear®.

Rated 2 out of 5 by from Liquid Plumr Maintenance Bottle Doesn't Work Well I usually buy the gold bottle that take care of everything, but thoughtI would try the regular maintenance version to see. It costs just as much as the gold bottle but less effective.
Date published: 2019-10-13
Rated 2 out of 5 by from Average - Get the Industrial Strength Instead! Liquid Plumber regular strength is good to use as a weekly pipe clear routine.  It is not meant to be used for standing water or slow moving pipe situations.
