Plumbing Design And Estimate By Fajardo Flashcards
Is defined as the art and science of installing pipes, fixtures, and other apparatus to convey and supply water in buildings and to dispose and discharge waste water and other liquids, gases, and other substances out of the buildings in safe, orderly, healthy, and sanitary way to ensure health and the sanitation of life and property.
Plumbing
Refers to a person who is skilled in the field of sanitation.
Plumber
Refers to an individual who worked on the sanitary field of ancient Rome.
Plumbarius
A metal used as plumbing materials by the Romans. Meant Lead and preferred for its malleability and resistance to acids.
Plumbum
Source of water supply and their means of transportation back before 40s decade.
Rainfall, river, springs, well, creeks, conveyed through Bamboo Pipes, By Man Himself, or by Animal Drawn Carts
Two main objectives of Plumbing
Supply water and Remove waste discharge
Conditions for an effective water supply in building.
Sufficient amount of water to provide each fixture; To prevent back-flow into the water supply system.
The system should accomplished the following:
Fast removal of waste with minimum leakage and stoppage; To prevent the entry of house vermin and obnoxious gases
All plumbing design and installations are governed by a set of rules and limitations prescribed by the National Plumbing Code, which provides that: “All drainage system must conform with a set of requirements enumerated as follows:
- Tightly Connected and Sealed 2. Properly Inclined 3. Adequate Clean out 4. Provision of Ventilation Pipe 5. Suitable trap for each fixture except water closet 6. Must be vented to avoid back flow and back siphonage.
To anyone, the word plumbing connotes fixtures and piping installations that will supply water and dispose waste in various forms. Waste is classified into two types:
Solid Waste and Liquid Waste
Waste is classified into two types. One of this is being discharged by water closet.
Solid Waste
Waste is classified into two types. One of this are waste that are coming from various fixtures other than the water closet or urinal.
Liquid Waste
Solid and Liquid waste are the two primary types of waste. These types of waste are also conveyed and disposed of by two types of drainage pipe. What are these pipes.
Soil Pipe and Waste Pipe
Any pipe that conveys waste from various fixtures other than the water closet and urinal is called -
Waste pipe
Those pipes that convey waste coming from the water closet and the urinal is called -
Soil Pipe
Unlike the waste pipe pipe, that is exclusively to receive discharges coming from the fixtures only, while the ________ can accept both wastes from water closet, urinal, and other fixtures.
Soil pipe
The drainage installation is sometimes referred to as DWV which means
D for drainage of solid waste, W for waste coming from various fixtures other the water closet, and V is for ventilation piping
A vent that does not carry water or water borne wastes.
Dry Vent
For the past several decades, the most popular and generally specified material for drainage system in buildings is the _______. It is durable, conveniently installed and answer to the most of plumbing needs of all types of building less than ________ high. However, buildings taller than this height do not specify this type of iron because of constant vibrations which causes water leak of the pipe joints.
Cast Iron Pipe; 25 story high
This type of cast iron pipe is generally used for building installation.
SV type
This type of cast iron pipe is classified as extra duty pipe used for underground installation
XV type
*Cast iron pipe has four Varieties
Standard Pipe; Single hub pipe; Double Hub pipe; Hubless Pipe
A pipe made from alloy of cast iron and silicon. It is widely used in chemical laboratories, industries and other installations where acid wastes are being discharge. Basically this type of pipe is brittle in character and requires stronger support for each pipe installed horizontally to prevent sagging of joints.
Acid resistant Cast Iron Pipe
Is made of asbestos fibers and Portland cement. The thickness of the pipe is twice as that of the standard cast iron pipe. This pipe could be used as soil, waste, and ventilation pipe and downspout. This kind of pipe is superior for embedment in concrete structure for having the same material properties.
Asbestos Pipe
