One of the simplest proactive steps is getting an annual plumbing inspection. These are often free or free with other services. The plumber will inspect all visible plumbing including fixtures, pipes, appliances, and drains. They diagnose and fix small problems before they become big ones. They can also tell you the best time to replace worn fixtures and appliances.

The U.S. Navy has a similar approach when working on jet engines. Engines requiring repairs are not simply yanked from the air frame and disassembled without first creating, then discussing, the maintenance plan or objectives with the shop boss. This keeps things flowing smoothly in a hanger where there would always be several jets in various stages of repair. It was much the same as a mold shop where a group of repair technicians work on multiple molds during the day or week, sharing equipment, tools, and space.

Accurate mold and tooling component assembly is a critical step in mold repair—and is the origin of many preventable, unscheduled mold stops (breakdowns). Poor workmanship and mistakes are usually a result of too much speed, lack of focus or physical skills, and disorganized work habits. If several repair techs are involved in the assembly of a mold, communication breakdowns between them can require the mold to be disassembled yet again to correct an oversight or install something that was forgotten.
Category 2 Water - Refers to a source of water that contains a significant degree of chemical, biological or physical contaminants and causes discomfort or sickness when consumed or even exposed to. Known as "grey water". This type carries microorganisms and nutrients of micro-organisms.
