Study Notes

Plumbing is the art and science of installing pipes, fixtures, and other apparatus to carry and manage water and other substances in buildings.
Plumbing systems move water into and out of buildings.
Plumber is a skilled person in sanitation, derived from the Roman word plumbarius.
Plumbing uses lead (Pb) as a metal.
Plumbing materials were crafted from clay, straw, copper, and terracotta initially.
Early methods included aqueducts, lead piping, flush toilets, and cast iron pipes.
Modern plumbing uses copper and PVC pipes.
Plumbing was introduced in the Philippines during the 17th and 18th centuries.
NAMPAP (National Master Plumbers Association of the Philippines) was created in 1935.
The Philippines adopted the Plumbing Code for the City of Manila (Ordinance 2411).
The Philippine Republic Act No. 1378 was legislated in 1955.
The 1959 plumbing code added asbestos cement piping.
The Republic Act No. 6541 Building Code in 1972 and a revised National Plumbing Code in 1996 were implemented.
Basic plumbing principles include supplying water, proper waste disposal, safety, and hygiene standards.

Principle 1: All habitable premises need clean water.
Principle 2: Plumbing fixtures have sufficient water at good pressure.
Principle 3: Plumbing design uses the least water necessary.
Principle 4: Water heating systems prevent explosions.
Principle 5: Plumbing in buildings touching roads, alleys, or easements must connect to a public sewer.
Principle 6: Every house needs at least a toilet and sink for kitchen and sanitation.
Principle 7: Fixtures are non-absorbent and have smooth surfaces.
Principle 8: Drainage systems prevent blockage issues like fouling, and have proper cleanouts.
Principle 9: Pipes need durability and effective workmanship.
Principle 10: Every plumbing fixture connected to drainage systems has a water seal trap.
Principle 11: Drainage pipes prevent clogging and provide sufficient air movement.
Principle 12: Vent terminals need proper air circulation and expulsion.
Principle 13: Plumbing systems undergo tests for leaks and defects.
Principle 14: No substance that clogs, explodes, or damages pipes is permitted.
Principle 15: Protect food, water, and sterile items from sewage contamination.
Principle 16: Water closets are properly located and ventilated.
Principle 17: If no sewer is in proximity, a regulated sewage system must be arranged.

NAMPAP hosts national and regional plumbing conventions.
NAMPAP hosts workshops with plumbing experts, tools, equipment, materials, and services presentations.
