1. 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.
2. How to Find Proper Drain-Cleaning Equipment
To make sure drain-cleaning equipment can handle the most demanding plumbing maintenance tasks in a facility, include answers to these questions in specifications:
- What is the range of pipe inside diameters to be cleaned?
- What power source is required? Electric? Pneumatic? Manual?
- What kinds of fittings are required? Screw-type? Root cutter? Short radius for sharp turns?
- What length cable? 25 feet? 50 feet? Longer?
- Are the proper type backflow preventers specified to protect the potable water supply when using flushing hoses?
Higher flow rates result in faster cleaning of loosened material.
