What features are generally associated with a main supply pipe? (Select all that apply.)
waste stack
water meter
vent stack
main shut-off valve
water meter
main shut-off valve
The features that are generally associated with a main supply pipe include:
1. Water meter: A water meter is typically installed on the main supply pipe to measure the amount of water being used.
2. Main shut-off valve: The main shut-off valve is used to control the flow of water into the building. It is usually located near the point where the main supply pipe enters the structure.
Therefore, the correct options are:
- Water meter
- Main shut-off valve
To determine the features associated with a main supply pipe, we can go through each option provided and analyze if it is generally present in such a system.
1. Waste stack: A waste stack is not typically associated with a main supply pipe. Waste stacks are vertical pipes that carry waste and sewage from different fixtures in a building to a sewer or septic tank.
2. Water meter: A water meter is commonly found in association with the main supply pipe. It is a device that measures the amount of water consumed and is usually installed on the main supply line, typically near the point of entry into a building.
3. Vent stack: A vent stack is not directly associated with a main supply pipe but is a crucial part of a plumbing system. Vent stacks are vertical pipes that allow air to enter the plumbing system, preventing pressure fluctuations and promoting the smooth flow of water through drain pipes.
4. Main shut-off valve: A main shut-off valve is a vital feature of a main supply pipe. It is typically located near the point where the main supply pipe enters a building and allows the water supply to be shut off completely in case of emergencies or repairs.
Based on the analysis above, the features generally associated with a main supply pipe are:
- Water meter
- Main shut-off valve
Thus, the correct options are "water meter" and "main shut-off valve."
