History of Plumbing
- Plumbing is the art and science of installing pipes for water supply and wastewater disposal.
- The Greco-Roman civilization significantly advanced plumbing practices.
- Romans developed the aqueduct, showcasing engineering skill and emphasizing hygienic water supply.
- The term "plumber" originates from "Plumbarius" (Latin for lead), referring to sanitation workers in ancient Rome.
Plumbing in the Philippines
- Prior to the 1940s, plumbing was viewed as a luxury and scarce among lower socio-economic classes.
- Rural households utilized indigenous methods for water supply and waste disposal, often neglecting sanitation risks.
- Water sources included rain, springs, wells, rivers, conveyed through bamboo or carried manually.
- There was an absence of water purity testing, leading to health issues related to contaminated water.
Waste Disposal
- Many relied on inadequate waste disposal methods, excreting in natural areas.
- Early plumbing solutions were basic, with toilets often being simple pits covered with materials like coconut trunks.
Plumbing Design
- Effective plumbing plans detail drains, supply lines, vent pipes, and fixtures to prevent future issues.
- Republic Act No. 1378 regulates the trade of master plumbers in the Philippines.
Basic Principles of the Plumbing Code of the Philippines
- Principle 1: Access to pure water is mandatory for all habitations.
- Principle 14: Prevent substances that can clog pipes or harm sewage disposal processes.
- Principle 15: Protect against backflow contamination.
- Principle 19: Maintenance must be done by Registered Master Plumbers.
- Principle 22: Waste should not enter water bodies without proper treatment.
Plumbing Objectives
- Ensure efficient water supply and sanitation in buildings.
- Provide sufficient water to all fixtures while preventing backflow.
Drainage System
- Two types of waste: solid (from water closets) and liquid (from various fixtures).
- Soil pipe: carries solid waste; waste pipe: carries liquid waste.
- DWV stands for Drainage of Solid waste, Waste Pipe for liquid waste, and Ventilation System.
Common Plumbing Terminologies
- Air Gap: Vertical space between a water supply and receptacle to prevent contamination.
- Backflow: Reversal of water flow into the potable supply.
- Sanitary Sewer: Designed to receive sanitary sewage and not surface or storm water.
- Trap: Device creating a liquid seal to prevent sewer gas backflow.
Plumbing Components
- Water Service Pipe: From main supply to building.
- Water Distributing Pipe: Conveys water to fixtures.
- Wet Vent: Receives waste discharge, excluding water closets.
