toilet connections and solvent weld

[Eddman]

hi there folks, just installing a new w.c. and basin using the 90degree pan coupler with 32mm spigot. I am using all push fit drainage from basin into spigot. I have the vent pipe in the corner of the room with a connection branch awaiting the toilet waste. because of heights, i am connecting the pan coupler to a 45degree angle to another 45degree angle and then a length of pipe into a boss connector in the vent pipe.My (hopefully) very easy and quick question is....do i need to use solvent weld on the pan coupler and the pan? Do i need to use solvent weld between pan coupler and end of the 45 degree bend? Do i need to solvent weld between the 2 bends and do i need to solvent weld between bends and pipe? Oh and also....do i need to solvent weld between new pipe and branch connector on the vent pipe?

all the pipes seem to fit quite snuggly with me just pushing them together but i don't know if the solvent weld makes sure there are no leaks.

thanks in advance for all helpful answers!

Are they ring seal fittings (rubber seal/ring in the collar)? If so you shouldn't use solvent weld.
