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.

1. A system configured to conserve resources, for use with a commercial laundry washing machine including a valve within a drain pipe section through which wash water from the washing machine is discharged into a waste water treatment or disposal system, the commercial laundry washing machine draining from a bottom of the washing machine, without any siphon break between the commercial laundry washing machine and where the wash water is discharged into the waste water treatment or disposal system, the system comprising: a portion of the drain pipe section exterior to the washing machine, upstream from where the drain pipe empties into a floor drain, or wall drain, at or below the bottom of the commercial laundry washing machine, the portion of the drain pipe section exterior to the washing machine and at or below the bottom of the washing machine being of a transparent material so as to allow an operator or technician to visually ascertain if water is draining through the transparent portion of the drain pipe section even though the valve is attempting to close. 2. A system as recited in claim 1, wherein the valve is a solenoid valve. 3. A system as recited in claim 1, wherein the transparent portion of the drain pipe section is downstream from the valve and upstream from the floor drain or wall drain. 4. A system as recited in claim 1, wherein the drain pipe section is unpressurized, the transparent portion of the drain pipe section further comprises an access port through a top surface of the transparent portion of the drain pipe section so as to be out of a flow path of wash water in the transparent portion of the drain pipe section to allow a technician to insert a test strip through the access port into the wash water discharged from the washing machine to test pH, bleach concentration, or other chemical characteristics of the discharged wash water. 5. A system as recited in claim 4, wherein the access port includes an elbow including an inlet leg, at least the proximal end of the inlet leg being disposed exterior to the drain pipe section, the inlet leg being disposed adjacent an outlet leg of the elbow, the outlet leg leading into a top interior portion of the transparent portion of the drain pipe section, oriented so that the outlet leg extends towards a bottom interior portion of the transparent portion of the drain pipe section. 6. A system as recited in claim 5, wherein the inlet leg is oriented so as to be substantially perpendicular and laterally sideways relative to a longitudinal axis of the portion of the drain pipe section in which the access port is disposed, the outlet leg being oriented so as to be substantially perpendicular and downward relative to the longitudinal axis of the portion of the drain pipe section in which the access port is disposed. 7. A system as recited in claim 6, wherein the outlet leg is substantially perpendicular relative to the inlet leg. 8. A system as recited in claim 6, wherein the distal end of the outlet leg disposed within the interior of the drain pipe section includes a sidewall which is tapered so as to be longer on an upstream side versus the downstream side. 9. A system as recited in claim 8, wherein an opening in the distal end of the outlet leg includes a curved scooped shape so that the upstream portion of the sidewall serves as a shield to minimize or prevent wash water flowing within the drain pipe section from entering into the access port. 10. A system as recited in claim 1, wherein the system further comprises the commercial laundry washing machine including a valve within a drain pipe section through which wash water from the washing machine is discharged into a waste water treatment or disposal system. 11. A system configured to conserve resources, for use with a commercial laundry washing machine including a solenoid valve within an unpressurized drain pipe section through which wash water from the washing machine is discharged into a waste water treatment or disposal system, the commercial laundry washing machine draining from a bottom of the washing machine, without any siphon break between the commercial laundry washing machine and where the wash water is discharged into the waste water treatment or disposal system, the system comprising: a portion of the unpressurized drain pipe section exterior to the washing machine, downstream from the solenoid valve, at or below the bottom of the commercial laundry washing machine, and upstream from where the drain pipe empties into a floor drain or wall drain that provides access to the waste water treatment or disposal system being of a transparent material so as to allow an operator or technician to visually ascertain if water is draining through the transparent portion of the drain pipe section even though the solenoid valve is attempting to close;the transparent portion of the drain pipe section further comprising an access port through a top surface of the transparent portion of the drain pipe section to allow a technician to insert a test strip through the access port into wash water discharged from the washing machine to test pH, bleach concentration, or other chemical characteristics of the discharged wash water. 12. A system as recited in claim 11, wherein the system further comprises the commercial laundry washing machine including a solenoid valve within a drain pipe section through which wash water from the washing machine is discharged into a waste water treatment or disposal system. 13. A method of conserving resources, the method comprising: providing a rigid transparent pipe portion to a rigid drain pipe of a commercial washing machine, which transparent pipe portion is exterior to the washing machine, downstream from a valve of the drain pipe associated with the washing machine, upstream from where the drain pipe empties into a drain that provides access to a waste water treatment or disposal system, the commercial washing machine draining from a bottom of the washing machine, without any siphon break between the commercial washing machine and where the wash water is discharged into the waste water treatment or disposal system, the transparent pipe portion of the drain pipe being at or below the bottom of the commercial laundry washing machine, which transparent pipe portion allows an operator or technician to visually ascertain if wash water is draining through the transparent drain pipe portion even though the valve of the drain pipe associated with the washing machine is attempting to close; andperiodically checking or instructing a user to check the transparent drain pipe portion to determine if wash water is draining through the transparent drain pipe portion even though the valve is attempting to close; andrepairing or replacing, or instructing a user to repair or replace the valve when wash water is determined to be draining through the transparent drain pipe portion even though the valve is attempting to close. 14. A method as recited in claim 13, wherein the valve is a solenoid valve. 15. A method as recited in claim 13, wherein providing a portion of the drain line comprises retrofitting the portion of the drain line of the commercial washing machine by replacing a portion of an opaque drain pipe section exterior to the washing machine and upstream from where the drain line empties into the waste water treatment or disposal system with a transparent drain pipe section, which allows an operator or technician to visually ascertain if water is draining through the transparent drain pipe portion even though a valve of the drain line associated with the washing machine is attempting to close. 16. A method as recited in claim 13, wherein the drain that provides access to a waste water treatment or disposal system is in a floor or wall. 17. A method as recited in claim 13, wherein the transparent drain pipe portion is checked each day of use of the commercial washing machine to determine if wash water is draining through the transparent drain pipe portion even though the valve is attempting to close. 18. A method as recited in claim 13, the method further comprising inserting or instructing a technician to insert a test strip through an access port provided in the transparent drain pipe portion, into wash water discharged from the washing machine to test pH, bleach concentration, or other chemical characteristics of the discharged wash water. 19. A method as recited in claim 13, the method further being for monitoring and maintaining the commercial washing machine, wherein: the transparent portion of the drain pipe is rigid;the transparent pipe portion drains from the bottom of the commercial washing machine into a floor drain; andwherein repairing or replacing, or instructing a user to repair or replace the valve comprises checking a valve door of the valve for fibers, degraded linens, or coins trapped against the valve door, preventing full closure of the valve door, the method further comprising removing any fibers, degraded linens, or coins that may be preventing closure of the valve door.
