That would depend on what type of stoppage FOG* or roots or gravel how one would clear it
* Fats oil greaseRent an auger and clear it yourself or call a plumber.
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
A trap doesn't cause the blockage. Something IN sewer line causes a blockage.
there is a blockage in your sewer line
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.
Not exactly a sewer main normally flows by graviety and a forced main is a pumped system
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.
3" house (building) drain allowable. 4" building sewer line needed for house from sewer main.

is is most certainly a blockage in the sewer line. Call a plumber to come and check it out and clean your sewer line for you.
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.
The only reason for this would be due to a blockage. Either snake your sewer line or call a plumber to carry out an investigation to find out where the blockage is.
This is due to a blockage on your main sewer line, this is an indication that it may just be starting and getting it cleared asap will be beneficial to you.
