Venting Code Flashcards
What is the maximum length of a vent pipe sized 3 inches?
61 m
What is the minimum size of a vent stack or stack vent?
One-half the size of the soil-or-waste stack at its base
True or False: The length of a stack vent or vent stack is its developed length from its lower end to outside air.
True
What is the minimum size of a vent stack serving a wet vent stack over 4 storeys high?
Full size of the wet vent to outside air
Fill in the blank: A stack vent shall be sized based on the total hydraulic load that is drained to the _______.
[lowest section of soil-or-waste stack or stacks]
What is the maximum length of a vent pipe sized 6 inches?
15 m
What is the maximum length of a vent pipe sized 4.5 inches?
30 m
What is the maximum length of a vent pipe sized 14 inches?
46 m
What is the maximum length of a vent pipe sized 12 inches?
30 m
Fill in the blank: For the purposes of sizing, the length of a vent stack or stack vent shall be its _______.
[developed length]
What is the maximum length of a vent pipe sized 9 inches?
30 m
What is the maximum length of a vent pipe sized 18 inches?
7.5 m
What is the maximum length of a vent pipe sized 76 inches?
Not Permitted
What is the maximum length of a vent pipe sized 245 inches?
7.5 m
What is the maximum length of a vent pipe sized 2200 inches?
Not Permitted
What is the maximum length of a vent pipe sized 5600 inches?
Not Permitted
What size should a vent stack or stack vent be based on?
Total hydraulic load plus any additional vent loads
What is the minimum size of a vent stack for a wet vent stack over 4 storeys high?
Full size of the wet vent
What is the minimum size of a vent pipe for a macerating toilet system?
Less than 1% inches
This refers to the sizing requirements for vent pipes in specific plumbing systems.
What hydraulic load does a wet vent serve?
Hydraulic load that drains to wet vent shall conform to specific sizing tables
This involves understanding the maximum permitted hydraulic loads as outlined in the relevant tables.
What is the maximum hydraulic load for two water closets draining to a wet vent?
2 fixture units
This indicates the maximum number of fixture units allowed for specific plumbing configurations.
What table is used to determine the size of individual and dual vents?
Table 2.5.7.1
This table provides the sizing guidelines based on the largest trap served by the vent.
When sizing an individual vent or dual vent, what factor is not considered?
Length
The length of the vent does not affect the sizing for individual or dual vents.
Branch vents, vent headers, circuit vents, and continuous vents shall be sized according to which table?
Table 2.5.8.3
This table outlines the sizing requirements for various types of vents.
What is the developed length of a branch vent?
From the most distant soil-or-waste pipe connection to a vent stack
This definition is crucial for understanding vent sizing calculations.
True or False: The length of a vent header is its developed length from the horizontal soil-or-waste pipe connection to outside air.
False
The length of a vent header is measured from its connection to a vent stack, not the horizontal connection.
What does the developed length of a continuous vent refer to?
From the vertical soil-or-waste pipe connection to a vent header or outside air
This measurement is essential for proper vent sizing.
Fill in the blank: The size of a wet vent is determined by the _______.
Hydraulic load from Table 2.5.8.1
This table outlines the maximum hydraulic loads that can be drained to a wet vent.
