A.0.5% to 1%
B.3% to 5%
C.Any slope, as long as water flows
D.1% to 2%
Explanation: Among the conditions to verify before installing, EC0324 requires measuring on site that the sanitary pipe has a slope (declive) of 1% to 2%. Its glossary defines pendiente as the drop from one point to another that the sanitary pipe needs to evacuate wastewater and rainwater.

4Which of these does EC0324 ask the plumber to mark directly on the construction site from the project, plans, or sketch?
A.Only the location of the water meter and the main shutoff valve at the entrance
B.The water and sanitary lines, drops, slopes, registros, and fixture positions
C.The electrical outlets, switches, and circuits near each fixture and appliance
D.The property boundaries and the setbacks from neighboring lots
Explanation: EC0324 Element 1 requires marking the hydraulic line, the sanitary line, the drops, slopes, and registros of the hydrosanitary network, and the altitude, length, widths, and centers of fixtures and equipment directly on site according to the project, plan, or sketch.
5Before installing, EC0324 asks the plumber to check the finished floor levels against the plan. What must be taken into account?
A.Only the ceiling height of each room where fixtures go
B.Only the color and size of the floor tile chosen by the client
C.The thickness of finishes, fill, and pipe diameters
D.The weight of the fixtures and the load rating of the floor
Explanation: EC0324 requires confirming against the plan that the finished floor levels (niveles de piso terminado) account for the thickness of finishes, fill (relleno), and the diameters of the pipes, so outlets and drains end up at the right height after finishing.
6How does EC0324 require pipes to be prepared before assembly?
A.Cut to length without burrs, bent and threaded as specified, stored per the manufacturer
B.Cut by eye and fitted later with extra couplings wherever the lengths fall short of the plan
C.Stored in direct sun so plastic pipe softens and bends more easily
D.Threaded only if a fitting feels too tight, and deburred only if visible
Explanation: EC0324 requires cutting pipe without burrs to the lengths specified in the project, plan, or sketch, making bends and internal or external threads as specified, and applying the manufacturer's recommendations for handling and stacking pipe.
