Adding Vent run to Soil Pipe Drainage and wastage systems and plumbing help, advice and answers

[nigrob]

Hi,
I have a 3 meter socketed soil pipe installed and connected to toilet and now wish to add the vent run.
Do I use a socketed pipe run with single socket bends ?

Are there any other options ?

Also to get the pipe round the roof line do I use 135 degree bends?

Thanks
