1. Which of the following is the standard material for residential
water supply piping in Alberta?
A. Cast iron
B. Copper
C. PEX
D. Galvanized steel
PEX is widely used in residential plumbing due to its flexibility,
corrosion resistance, and ease of installation.
2. The primary purpose of a trap in a plumbing system is to:
A. Increase water pressure
B. Prevent sewer gases from entering the building
C. Filter debris
D. Control water temperature
A trap holds a small amount of water that blocks sewer gases from
entering occupied spaces.
3. What is the minimum slope required for a 3-inch horizontal drain
line according to the Alberta Plumbing Code?
A. 1/16 inch per foot
B. 1/8 inch per foot
C. 1/4 inch per foot
D. 1/2 inch per foot
, Proper slope ensures adequate drainage and prevents blockages.
4. When soldering copper pipes, it is essential to:
A. Apply flux only after heating
B. Clean the pipe and fitting, apply flux, and heat evenly
C. Heat one side of the fitting only
D. Use water to cool immediately after soldering
Cleaning removes oxidation, flux promotes solder flow, and even
heating ensures a leak-free joint.
5. When joining PVC pipes, the primer is used to:
A. Seal the pipe

contaminating potable water C. Water pressure fluctuations
D. Air entering the water system
Backflow can introduce contaminants into a drinking water system,
so prevention devices are critical.
7. The primary function of a vent pipe is to:
A. Increase water pressure
B. Allow air to enter the drainage system to prevent siphoning
C. Carry sewage to the main line
, D. Filter water entering the system
Vents maintain proper pressure and allow waste to flow smoothly.
8. Which type of valve is typically used to control water flow to
a fixture? A. Gate valve
B. Globe valve
C. Angle stop valve
D. Butterfly valve
Angle stop valves provide localized control at fixtures for
maintenance and repair.
9. What is the maximum allowable temperature for domestic
hot water supplied to a fixture?
A. 45°C
B. 55°C
C. 60°C
D. 70°C
