Study Notes

Plumbing Basics

Plumbing has two main objectives: supplying water and removing waste.
Air gap: Prevents backflow of water by creating an unobstructed vertical distance between the water supply and a tank.
Backflow: Water or other substances flowing from a non-potable source into the potable water supply.
Riser: A vertical water supply pipe that conveys water to branches or fixtures.
Standpipe: A vertical pipe used for water storage, often under pressure.
Liquid waste: Discharge from fixtures, appliances, or appurtenances.
Relief vent: Provides air circulation between drainage and vent systems.
Lateral: A secondary pipe in plumbing or a common sewer that doesn't have other sewers feeding into it.
Main vent: The primary artery of the venting system, connecting vent branches.
Stack venting: Venting a fixture or fixtures through the soil or waste stack.
Wet vent: A vent that carries the discharge from wastes other than toilets.
Dry vent: A vent that does not carry water or waterborne wastes.
Continuous vent: A vertical vent that is a continuation of the drain it connects to.
Common vent: A drain from two or three fixtures connected to a single trap. Also known as a dual vent.
Cross connection: Any physical connection between two separate piping systems, one potable and one potentially contaminated, that allows water to flow between them.
Dead end: A portion of a pipe closed at one end, allowing stagnation of water or air.
Solid waste: Waste being discharged by water.
Liquid waste: Waste coming from various fixtures.
Waste pipe: Conveys liquid waste from fixtures other than toilets.
Soil pipe: Conveys waste coming from toilets.

Plumbing Materials

Acid resistant cast iron pipe: An alloy of cast iron and silicon, commonly used in chemical laboratories.
Asbestos pipe: Made from asbestos fibers and Portland cement. Twice the thickness of standard cast iron pipe.
Cast iron pipe: The most common material for drainage systems.
- SV type: Used for building installations.
- XV type: Extra heavy-duty pipe used for underground applications.
Cast Iron Pipe Varieties: Standard, Single Hub, Double Hub, Hubless.
Galvanized steel pipe: Made from mild steel, often corroded by alkaline and acidic water.
Bituminous fiber sewer pipe: The cheapest sewer pipe option.
Vitrified clay pipe: One of the oldest materials used for sewer lines.
Galvanized wrought iron pipe: Superior to galvanized steel pipe for plumbing installations, more resistant to acid waste.
Brass pipe: Expensive, made from an alloy of zinc and copper.
Copper pipe: Durable and highly resistant to corrosion.
Plastic pipe: A newer plumbing material introduced in the Philippines.
Lead pipe: One of the oldest plumbing materials, used by Egyptians, Greeks, and Romans.
