Calcium (uric salt) build-up is the #1 culprit for expensive plumbing calls regarding slow running or plugged urinals. Over time, calcium build-up develops at the effluent drain opening and far down the pipeline.

The use of enzymes, cleaners, and fragrances WILL NOT dissolve these calcium ROCKS!

Cal-Solv will dissolve these calcified rocks and eliminate the harborage of odor causing bacteria.
