Study Notes
Cold-Water Distribution System
- Service Pipe: Transports water from the main water supply to the building.
- Water Meter: Measures the amount of water consumed in liters or gallons.
- Horizontal Supply Main: Main distribution pipe that runs from the water meter to the fixtures.
- Riser: Vertical pipe connecting the water meter to fixtures on different floors.
- Fixture Branch: Individual pipe connecting the main to a specific fixture (e.g., faucet, toilet).
- Controls & Valves: Devices regulating water flow, pressure, and direction throughout the system.
Upfeed System - Advantages and Disadvantages
- Disadvantages:
- Insufficient pressure for tall buildings
- Reduced water supply during peak demand
- Advantages:
- Cost-effective as it avoids pumps and tanks.
Gravity Supply Tanks
- Components:
- Supply Pipe
- Inlet
- Overflow
- Pipe
- Drip Pan
- Gate Valves
Pneumatic Water Tanks
- Can be centralized or per bathroom group.
- Uses a pressure relief valve to regulate pressure.
Storage Tank
- Large hot water tank (60-130 cm diameter, 5m max length)
- Made of heavy-duty materials with rust-proof paint.
Plumbing and Sanitary Systems
- Definition: Plumbing involves the installation, maintenance, and repair of water supply, drainage, and venting systems.
- Application: Covers a wide range of systems including potable water supply and distribution, sanitary and storm drainage, vent pipes, roof drains, leaders and downspouts, building drains and sewer, devices, receptacles, appurtenances, water lines, potable, tap, hot and chilled water piping, potable water treating equipment, fuel gas piping, water heaters, and vents.
Sump Pumps
- Used to remove excess water from a specific area.
- A category of pumps that are used to pump out different fluids.
Valves - Function
- Control of the water system
- Start or shut down a system
- Regulate pressure
- Check backflow
- Control the direction of water
Location of Utilities
- Effective management of building pipes and fixtures after installation is crucial for building performance and occupant comfort.
- The term "plumbing system" encompasses all potable water supply and distribution pipes, plumbing fixtures and traps, sanitary and storm drainage systems, vent pipes, roof drains, leaders and downspouts, building drains and sewers, devices, receptacles, appurtenances, water lines, potable, tap, hot and chilled water piping, potable water treating equipment, fuel gas piping, water heaters, and vents.
