Yes. if local codes allow and if all fixtures are vented and the fixture units do not exceed the waste line they are connected to
3" house (building) drain allowable. 4" building sewer line needed for house from sewer main.
Either they are on a separate sewer line and connect to the main sewer line later on or they sewerage is pumped by means of a machine into the main sewer line.
Yes i drain line has got to be vented. A sewer line creates gases which has to be vented otherwise two things happen. Either, you get terrible smells around your property or your sewer lines can explode due to trapped sewer gases, this is costly and can be a painful smelly experience.
Not exactly a sewer main normally flows by graviety and a forced main is a pumped system
Unless you know that there is one in the line before it gets to the main line, you should. Sewer gas can come up that drain just like any other.
Could be caused by a couple of things. If you have an onsite septic system (tank and drain field) the tank may be full, and the rainwater is causing it's contents to backup the main drain back in to the house. A vent pipe could be plugged, which causes the sewer gas to back up. If you are hooked to a public sewer, there may be a blockage in the main drain out to the line in the street. Have a plumbing contractor check it out. It can be very dangerous.

You have a main sewer line stoppage and you need to have your drain pipe roto-rootered.
Anytime I have plummbed a house, I always start on the far end of the drain system and slowly drop the grade as I work my way to the main drain. Just always remember sh!t rolls downhill. goodluck
It goes into the main sewer system. It will go through your sewer system and then out to the main sewer. That is if you live in town!
The drain pipe has a blockage somewhere downstream from where the toilets are connected to the main sewer line from the house. All the drains in a house normally connect to one main line that either goes to the city sewer system or your septic tank. If you know where the sewer line exits the house, you could check there to see if the blockage is in the yard. Most sewer blockages are caused by tree roots, broken fittings, or crushed pipes. Good Luck
Firstly, you have a anti syphon problem, this is causing the drainage and the bubbles are caused by a possible blockage in your main sewer line.
