Systems and related methods for conserving various resources, such as, but not limited to, water, laundry chemicals, natural gas, electricity, linen, labor, and wear on equipment (e.g., a solenoid valve of a commercial washing machine drain line). The inventor has spent the past 14 years in the industrial chemical field, allowing him to access and service commercial washing machines, and has discovered that drain issues relative to such commercial washing machines result in enormous losses to such institutions that process a large volume of laundry. Such typical institutions include, but are not limited to, hotels, hospitals, prisons, universities, colleges, laundries, and nursing homes. By replacing a portion of the opaque drain pipe section between the valve and the floor drain, operators and technicians can quickly determine if a leak is occurring, and take corrective action. An access port may also be provided to test characteristics of discharged wash water.
