Tips for Managing Water Systems in Existing Buildings

Problems in drain lines are no justification for wasteful consumption. Instead, consider these tips for managing waste systems in existing buildings:

• When replacing fixtures with lower-flow models, inspect drain lines for corrosion and other conditions that obstruct the flow.
• Clean waste lines when replacing fixtures.
• Consider using toilet paper with lower tensile strength for lines prone to clogging.
• Carefully consider reduced fixture flow rates for toilet fixtures located at the beginning of long horizontal runs.
• During product specification, consider the placement of high-efficiency toilets and other nearby fixtures within the system.
• Discourage building occupants from flushing paper towels and other items not meant for the sanitary system.
• Consider the suitability of the waste-pipe material and maintenance procedures before connecting waterless fixtures.

From a sustainability perspective, we need to think more broadly about conserving the water facilities use daily, as well as about maintaining existing buildings so they provide long-term value for the resources they require during construction and operation. For plumbing systems, this means considering water-conservation measures, as well as the way decisions are inherently tied to waste systems and their ability to operate efficiently.
