Rating Newest Oldest. Best Answer: The short answer is YES you need a vent. Toilets themselves are self venting in that they vent to the pipe directly below them. The vent is the tall tube in the tank of the toilet.BUT the drain pipe below the toilet will need to be vented as well so this is perhaps where your confusion lies.oilets are not self venting they do have a built in trap so that is probably your confusion. The main stack the toilet is tied into is also the main vent for your whole plumbing system so as long as the toilet is with in a couple of feet of it you do not need a vent. Donald P Â· 7 years ago.
