According to Flushing Action:
* Flushes through a simple wash down action
* Discharges waste into a trapway located at the front of the bowl
* Has a bulge on the front
* Has a small amount of standing water
* Cost less but is least efficient and noisiest
soil fixtures
Wash down
Flushes through a siphon
action created in the trapway
soil fixtures
Reverse Trap
- has a larger trapway making it less likely to clog
- Quieter flushing action
- Retains a large amount of standing water
soil fixtures
siphon jet
- Less noisy and very efficient
- Flushing action is started by a whirlpool motion followed by a complete flush down
- Retains a large amount of standing water
soil fixtures

pipe and fitting types: (11)
- cast iron soil pipe
- acid resistant cast iron pipe
- asbestos pipe
- Bituminous Fiber Sewer Pipe
- Vitrified Clay Pipe
- Lead Pipe
- Galvanized Steel Pipe
- Galvanized Wrought Iron Pipe
- Copper Pipe
- brass pipe
- Plastic or Synthetic Pipe
- Most popular and generally specified material for drainage installation. Extensively used in the 60s and 70s.
- Durable, conveniently installed (<25 storey)
- Commercial length: 600 cm
- Diameters: 50-150mm
- Affected to some extent by corrosion by acid formed by Carbon Dioxide, Sulphur Oxide, and Methane Gases that create rust
cast iron soil pipe
types of cast iron soil pipe: (2)
SV type - generally used; for building installations
XV type - extra duty; for underground installations
cast iron pipe varieties (4)
- standard pipe
- single hub pipe
- double hub pipe
- hubless pipe
- Made of an alloy of cast iron and silicon
- Installed in chemical laboratories, industries and other installations where acid wastes are being discharged
- Brittle and cracks easily, thus horizontal runs have to be Supported at every 1.50 meter interval to prevent sagging
Acid Resistant Cast Iron Pipe
- Made of an asbestos fibers and portland cement
- Used as soil, waste, ventilation pipe & downspouts
- Suited for concrete embedment because of similar properties
Asbestos Pipe
- Cheapest of all types of pipes
- Light in weight, slightly flexible and can take slight soil movement
- without danger of cracking or pulling out of its joints. It is thus suited for house sewer and septic tank installations
- may be softened/damaged by excessive hot water or chemical flow
Bituminous Fiber Sewer Pipe
- One of the oldest materials used for sewer lines
- Highly resistant to most acids
- Because it is made of clay, it is brittle and cracks easily when laid on unstable ground
- Made in short lengths of 750mm
Vitrified Clay Pipe
- The oldest pipe used for plumbing systems
- Highly resistant to acid
- Poisonous and injurious, is therefore not recommended to convey water for human consumption
Lead Pipe
- Made out of mild steel and expected to last 15 to 25 years
- Subject to deposits of salt and lime which can cause FHL
- Comes in several commercial sizes: 10 (3/8”), 13 (1/2”), 20 (3/4”)
- 25 (1’), 32 (1¼”), 38 (1½”), 50 (2”), 75 (3”), and 100 (4”)
Galvanized Steel Pipe
- Better then steel pipe for plumbing installation
- More resistant to acid waste
Galvanized Wrought Iron Pipe
- Durable and extremely corrosive resistant
- Easy to install
- Smooth interior surface
Copper Pipe
Copper pipe classification
- K type- heaviest; recommended for underground installations
- ** L type**- lighter; available in both rigid and flexible form; recommended for residential water supply line and radiant heating installations
- ** M type**- thinnest; available only in rigid form; for small water supply lines and radiant heating installations
- Most expensive
- Made of an alloy or zinc (15%) and copper (85%)
- Resistant to acids and has a smooth interior surface
Brass Pipe
- Developed in Germany in 1935
- Most are produced from synthetic resins
- Superior type of pipe because it weighs less, is easy to cut, is flexible, has a smooth interior surface, and is cheaper than steel
Plastic or Synthetic Pipe
Plastic or Synthetic Pipe TYPES:
Rigid type (pipes)
Flexible type (tubing)
Considerations in choosing
materials: (4)
- Quality and durability.
- Resistance to external and internal contact with foreign matters.
- Resistance to acid waste and other chemical elements that will pass into it.
- Cost of materials and labor.
