Guess everyone has forgot or gave up.

Maybe have all the books they need.

Someone will get it. I missed it by one. No cigar though.

1. The size of the sewer pipe should be equal to the size of the vent pipe through the roof. T/F
False - The aggregate size of the vents must be equal to the largest sewer connection, but the sewer need not be as big as the aggregate vent size (UPC 904.1)

2. You are only allowed up to 8 fixtures on a 2" vent pipe? T/F
False. Capacity is determined by fixture units. A lavatory sink is only one fixture units

3. Drain- waste and vent pipes can be tapped if air gap is 6" above flood level? T/F
True. If by “tapped” you mean connection between them

4. You can combine separate vents of smaller size to equal the sewer vent size? T/F
True. to satisfy the aggregate vent size requirement to be at least the same as the largest sewer connection from UPC 904.1 (we are talking logically vs physically combining them)

Boner question is: Um False.

Exactly
