Taiwan Building Plumbing System Design Codes
Context & Purpose
This skill encodes the Taiwan "Building Water Supply and Drainage Equipment Design Technical Specifications" (建築物給水排水設備設計技術規範). Use it to validate MEP plumbing drawings.
Design Parameters & Constraints
1. Water Tank Capacity (水箱/水塔容量)
- Total Storage (地下水池 + 屋頂水塔): Should generally hold 1 to 2 days of the building's estimated daily water demand.
- Ratio: Typically, the roof tank holds 1/10 to 1/3 of the daily demand, and the underground reservoir holds the rest.
2. Water Supply Pipe Sizing (給水管徑計算)
- Sized based on Fixture Units (F.U.).
- Velocity Limits:
- Main/Branch pipes: 0.9 m/s to 2.0 m/s. (Max 2.0 m/s to prevent water hammer and noise).
3. Traps & Water Seals (存水彎與水封)
- Water Seal Depth (水封深度): Must be between 5 cm and 10 cm.
- Every sanitary fixture must have a trap. Double trapping (雙重存水彎) is strictly prohibited.
4. Drainage Pipe Slopes (排水管洩水坡度)
- Pipe Diameter ≦ 65mm: Slope ≧ 1/50
- Pipe Diameter 75mm - 150mm: Slope ≧ 1/100
- Pipe Diameter ≧ 200mm: Slope ≧ 1/200
5. Vent Pipe Systems (通氣管路)
- Stack Vent (伸頂通氣管): Must extend at least 15 cm above the roof. If the roof is accessible, it must extend at least 2 meters above the roof.
- Vent pipes must not connect to HVAC exhaust or chimney flues.
Execution Logic for AI
When reviewing plumbing plans:
- Verify drainage slopes match the pipe diameter (e.g., a 100mm pipe must have at least 1/100 slope).
- Check water seal depth specifications (must be 5~10 cm).
- Confirm roof vent pipe heights.
