17
Q

What size should a vent stack or stack vent be based on?

A

Total hydraulic load plus any additional vent loads

18
Q

What is the minimum size of a vent stack for a wet vent stack over 4 storeys high?

A

Full size of the wet vent

19
Q

What is the minimum size of a vent pipe for a macerating toilet system?

A

Less than 1% inches

This refers to the sizing requirements for vent pipes in specific plumbing systems.

20
Q

What hydraulic load does a wet vent serve?

A

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.

21
Q

What is the maximum hydraulic load for two water closets draining to a wet vent?

A

2 fixture units

This indicates the maximum number of fixture units allowed for specific plumbing configurations.

22
Q

What table is used to determine the size of individual and dual vents?

A

Table 2.5.7.1

This table provides the sizing guidelines based on the largest trap served by the vent.

23
Q

When sizing an individual vent or dual vent, what factor is not considered?

A

Length

The length of the vent does not affect the sizing for individual or dual vents.

24
Q

Branch vents, vent headers, circuit vents, and continuous vents shall be sized according to which table?

A

Table 2.5.8.3

This table outlines the sizing requirements for various types of vents.

25
Q

What is the developed length of a branch vent?

A

From the most distant soil-or-waste pipe connection to a vent stack

This definition is crucial for understanding vent sizing calculations.

26
Q

True or False: The length of a vent header is its developed length from the horizontal soil-or-waste pipe connection to outside air.

A

False

The length of a vent header is measured from its connection to a vent stack, not the horizontal connection.

27
Q

What does the developed length of a continuous vent refer to?

A

From the vertical soil-or-waste pipe connection to a vent header or outside air

This measurement is essential for proper vent sizing.

28
Q

Fill in the blank: The size of a wet vent is determined by the _______.

A

Hydraulic load from Table 2.5.8.1

This table outlines the maximum hydraulic loads that can be drained to a wet vent.
