Yes if the vent pipe is 4" and vertical by code and there is nothing connected between your toilet tee and where you would connect your new toilet tee. If not worried about codes then yes you can connect to a 3" vent line if no other vent lines are connected down stream. If you have a vent pipe that is less then 3" and or you have other vents connected between your old toilet tee and your new toilet tee then NO you can not connect a new tee for your toilet.
Yes. If not it will be a wet vent and cause MAJOR problems.
where one toilet is draining to its own unshared line, the line can be 3" but once both toilets are draining to the same line, it needs to be 4". in other words, from the first toilet to the second toilet can be 3" but past the second toilet needs to be 4". there needs to be a vent downstream of the second toilet in the direction of flow if there is another fixture of any kind downstream of the two toilets.
You will either have to break up the concrete to tie into the under-slab main waste pipe, or you will need to build a subfloor high enough to run the drain pipes underneath, and then connect into the main drain above grade. Keep in mind that you will need some amount of fall (slope) on the pipe, and that you will also need to tie in to the vent stack, or run a new vent through the roof. This should be 4"ABS for a toilet, and 1 1/2" - 2"ABS for a sink or shower.
You can, I'm not sure that I would. Probably doesn't pass code for one thing. If that is not an issue, that is the main stack. Down to the sewer, up to the roof vent. If you attach a sink drain there, when the toilet is flushed, it will pull venting from wherever it can. Most will still come down from the roof, but being as close as it is, it will also pull from the sink drain and cause a gurgling from the sink. The other consideration is the sink itself. Make sure it has an overflow vent in the rim of the sink. If the one you use doesn't the drain will need a vent of its own, otherwise the sink drain will be trying to pull against a vacuum. Another thought. They make what is called a Saddle Clamp to do what you are talking about. A half piece of pipe with a female connection in the side of it. Made of PVC and held on with two clamps that go around the existing pipe.
You need a new wax ring.

The short answer is yes, but like all answers comes with conditions. In a traditional residential plumbing system all drain lines eventually connect together, everything is interconnected.The long answer is that connecting fixtures to a drain system must follow certain rules and good practices which have been proven over time. Assuming you have a rudimentary knowledge of plumbing systems you may proceed with the following.You may connect to your horizontal toilet waste pipe but should be 3-5 pipe diameters downstream any vertical portion (like where it turns up to the toilet, or turns to go up a wall for an upstairs toilet.) If you do connect to a horizontal portion the new pipe must be sized to serve as both a drain (for the new fixture) and as a vent (for both the new fixture and the toilet.) this means that the new drain must connect back into the vent system (at least 6" higher than the rim of the highest fixture connecting to that system) OR must vent separately out the roof of the building or through an approved air admittance device. (basically an air valve in the cabinet or wall space that lets air into the system but not out. - -air valves have special provisions and are tricky so research them thoroughly before installing one.)You may also connect to a vertical stack. (a large pipe serving fixtures on the floor above) When connecting to a stack you need only size the new pipe to serve as a drain and vent for the new fixture. Generally you may connect to any portion of the vertical stack (high or low) as long as you use a wye branch fitting or other approved drainage pattern fitting. hope this helps.
2" VENT. Many codes say the vent can be 1/2 the size of the pipe being served but in no case less then 11/2" and considering a lead bend (toilet drain) can be 3" and the new fixtures have 1.6 GPF in lieu of the 3.5 GPF a 11/2 vent pipe is fine

Normally 11/2" vent and a 3" soil line=BUT some codes want a 4" waste and then a 2" vent may be required depends on the local inspector=

To install a new toilet flange, first remove the old flange and clean the area. Place the new flange over the drain pipe and secure it with screws. Make sure it is level and properly aligned. Finally, connect the toilet to the flange and secure it in place.
To properly install a new toilet flange, first remove the old flange and clean the area. Place the new flange over the drain pipe and secure it with screws. Make sure it is level and flush with the floor. Finally, connect the toilet to the flange using a wax ring and bolts, then secure the toilet in place.
To relocate a dryer vent in a home, follow these steps: Determine the new location for the vent, ensuring it meets building codes and is easily accessible. Turn off the power to the dryer and disconnect the vent pipe from the dryer. Remove the existing vent pipe from the wall or ceiling. Install a new vent pipe in the desired location, making sure it is properly sealed and secured. Connect the new vent pipe to the dryer and ensure it is properly aligned. Test the dryer to ensure proper ventilation and functionality.
To install a toilet in your bathroom, first turn off the water supply and remove the old toilet. Place a new wax ring on the flange, then carefully lower the new toilet onto the flange and secure it in place with bolts. Connect the water supply line and tighten the connections. Finally, test the toilet for leaks and make any necessary adjustments.
The toilet is 3 or 4 inch and the shower is 1 1/2 or 2 inch. You could reduce the toilet to 2 inch, but it would never flush correctly or be of much use. The current toilet drain has no trap in that section because one isn't needed. The toilet itself is the trap. If you are using existing waste lines, they should already be connected to the vent stack. If you are adding lines, connecting to the existing stack is fine as long as it is above the last drain.
The biggest difference from an old toilet to a new one is the water consumption. An older toilet can use up to 16L of water per flush! A modern toilet only uses between 3-5L per flush. A big money saver!
