Study Notes

Plumbing Overview

Plumbing encompasses systems that convey fluids, including potable water and waste removal.
It includes components like pipes, valves, tanks, and fixtures essential for distribution and sanitation.

Revised Plumbing Code and Legislation

Hermogenes Pobre, as PRC Chairman, adopted the Revised Plumbing Code of 1999.
Republic Act 1378, known as the Plumbing Law, was approved by President Joseph Ejercito Estrada on December 21, 1999.

Major Parameters of Plumbing

Waterline System:
- Delivers fresh, potable water via cold and hot water lines.
- Cold waterline connects to municipal sources for direct supply.
- Hot waterline supplies heated water to fixtures.
Sanitary Line System:
- Underground pipes transport sewage from various fixtures to treatment plants.
- Distinguishes between types of waterborne waste:
  - Grey water: less polluted wastewater from sinks and baths.
  - Black water: waste from toilets.

Plumbing Terminologies (RA 1378)

Contamination: Impairs potable water quality, posing public health hazards.
Conductor/Downspout: Vertical pipe for rainwater drainage.
Corporation Cock: Stop valve connecting water service pipes to mains.
Developed Length: Length measurement of piping including fittings.
Domestic Sewage: Waste from everyday living, excluding industrial waste.
Drain: Pipe carrying storm and wastewater into drainage systems.
Drainage System: Piping that routes sewage and liquid waste to legal disposal points, not including public sewer mains.
Fixture: Receptacle in plumbing systems for water or waste collection.
Fixture Unit: Measurement of load or water requirement influenced by fixtures; one unit corresponds to 28.3 liters/minute.

Hydrological Processes

Natural Water Cycle: Illustrates the movement of water through various phases [vapor, liquid, solid] across the atmosphere and Earth.
- Processes:
  - Condensation: Water vapor converting to liquid.
  - Precipitation: Water forms (rain, snow) fall from clouds.
  - Surface Water Runoff: Precipitation that flows over land to rivers and oceans.

Engineered Water Cycle

Human-centered approach for sourcing, treating, and reusing water.
Prioritizes safe drinking water and wastewater management for environmental protection.

Properties of Water

Polarity: Water molecules have a distinct charge that enables it to dissolve substances.
Solvent Capabilities: Known as the "universal solvent," effective in dissolving numerous substances.
Heat Capacity: Requires significant energy to increase water temperature, contributing to climate regulation.
High Heat of Vaporization: Water's evaporation process absorbs heat, providing cooling.
Cohesion and Adhesion: Cohesion bonds similar molecules, while adhesion bonds different molecules.
Density Variation: Ice forms a less dense crystalline structure, allowing it to float.

Impurities of Water

Common impurities include dust, dirt, and harmful chemicals such as lead, nitrates, pesticides, and mercury.
Various treatment methods exist, like filtration and boiling, for removing certain impurities.
