Can you hook a water drain pipe to a 3'' sewer pipe and it be safe?
If you are talking about a roof water drain pipe to sewer it is illegal. If you are talking about a sink drain pipe well that is where they all connect to so yea.
can a clogged vent pipe cause leaking onto the roof and bust a joint in the sewer line?
Yes
What is the purpose of the ventilation pipe in a plumbing system?
It allows the drains to flow freely and the stench of the sewer to be sent to the highest point in the roof. That is why p-traps are installed, so the sewer gasses go to the roof vents and not through the water in the traps.
What is the height of the sewer vent pipe above the roof?
A vent Terminal and depending if the roof is strictly for weather protection it terminates about 24" above the roof. If the roof area is for people then it is 7 ft above the roofing surface.
How can you clean roof sewer vents?
Very rarely will a roof sewer vent need to be cleaned. On the occasion that you need to remove debris or a nest, the best way is to try a shop vac. Then you could try a hose to clear any other items down thru the drain pipe. These methods should be adequate to remove 99% of the blockages. Never try to snake a roof vent! There are too many dangers and problems that may occur from trying to do so.
What is a pipe extended above the roof level called?
A pipe extended above the roof level is a soil pipe.
How come your 40-year-old house that has had no plumbing problems did not have any smoke come back up out of the roof pipe when a smoke bomb test in the manhole sewer system was conducted?
This could have occured if the sewer lateral line has a belly (low spot) in it. It would cause the line to be full of efluent thus keeping the smoke from flowing up to your roof vent.

Where are your sewer vents?
A vent pipe is located afte a fixture trap to remove dangerous fumes from the system and exhauts them through the roof terminal as the fresh air enters through the fresh air inlet
Can I increase the height of the sewer vent pipe which is below the ridge line of the house to reduce the occasional smell of sewer gas outside when the wind blows just right?
Of course, the codes do require a minimum of height and diameter (normally 4" to prevent hoarfrost) and depending if the roof is used for weather protection I have installed vent piping 7 feet above the roof to prevent sewer fumes from entering the structure and 7 feet is the min required for promenade roofing systems.
Will acid decompose a dead animal in a roof vent pipe?
Yes, acid will decompose a dead animal in a roof vent pipe. Lye or refined lye caustic soda will dissolve organic materials without hurting the pipes. But the best way to remove the obstruction would be the hook end of a coat hanger, the retriever head of a sewer snake, or the treble hook of a strong cord.
When the washer drains it sucks the water out of the toilet?
Sounds like your washer doesn't have a connection to your "stack pipe". As water moves through a drain pipe, it creates a vacuum behind it, the "stack pipe" or "vent pipe" is usually a pipe that goes through the roof of your house and provides an open air connection to all of your plumbing fixtures so the vacuum is provided a way to suck air rather than sucking the water out of your "P" traps or other fixtures such as your toilet. Chances are your toilet is also "sucking" from your washer, but you just don't notice it. It is also dangerous because if the washer or other fixtures are sucking water out of your "P" traps, then you may be getting methane and other sewer gases into your house. Have a pipe run from washer drain to your vent pipe and this should eliminate the problem. Be sure it connects to the vent pipe because if you ever have a sewer backup, the vent system won't allow the gray water to empty into your house through the air pipe.
