Plumbing General
Description
- General plumbing in NYCHA developments encompasses the design, installation, and maintenance of sanitary drainage and stormwater management systems. These systems ensure the efficient disposal of wastewater from bathrooms, kitchens, and other facilities while adhering to NYC plumbing codes and health regulations. Proper venting, traps, and cleanouts are implemented to maintain system integrity and prevent backflow or odor intrusion into living spaces. Additionally, stormwater drainage is carefully managed to prevent contamination, with backwater valves installed in flood-prone areas. The plumbing infrastructure is designed to be both hygienic and environmentally responsible, supporting the long-term functionality of NYCHA properties
RAD Conversions
- Existing plumbing systems should be thoroughly investigated through on-site inspections and testing and ensure proper allowance for percent repair or replacement, as indicated in cost estimates, if full replacement is not required.
- RAD Conversion Partners should identify in their proposed building systems scopes where a proposed approach to heating and cooling and domestic hot water repair, replacement, or conversion may allow for abandoning certain plumbing infrastructure in place.
- RAD Conversion Partners should consider enclosing existing pipe chases. At a minimum, existing exposed piping should be sanded and repainted. Piping should be insulated where indicated for Local Law compliance and Enterprise Green Communities certification.
