Abstract: Cleaning operations involving steam and flushing with water produce runoff that flows into drains installed in factory floors. Allowing bulky materials to flow into and plugging factory drains creates floor flooding conditions, production line shutdown and loss of time and money. These conditions can occur when strainer baskets are removed from drains. A drain facilitated with a drain closer prevents flow of bulky materials into drains and subsequent plugging. The drain closer is activated with a modified strainer basket such that removal of the basket closes the drain preventing inflow of bulky materials.
