    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.
