How big is the vent for a toilet?
The toilet vents connect to the plumbing vent stack. The waste pipe leading away from a typical toilet measures 3 inches in diameter, although some houses have 4-inch pipes.

Do you need a plumber to vent a toilet?
If you don’t know how to vent a toilet, you can always hire a plumber, but if you’re installing the toilet drain pipe yourself, adding the vent is fairly easy. The actual vent configuration depends on factors such as the toilet location with respect to the home’s existing vent system and whether it’s on the ground floor or an upper story.
How do you connect a vent to a toilet?
Connect the Vent Underneath the Toilet: If the toilet waste pipe drops vertically to a long-sweep elbow, you can install the vent in the vertical pipe before the fitting. You would do this with a reducing wye with its sweep pointing downward and use elbows to change the direction of the vent pipe as needed.
How does a plumber plumbed a new toilet?
So the plumber had plumbed the new toilet by cutting into (intercepting) the waste pipe from existing toilet to the soil pipe. Therefore the waste from both toilets is effectively going out to the soil pipe from one pipe.
What is the distance between the toilet and the vent?
The Toilet’s Trap Arm Length (aka Trap To Vent Distance). The toilet’s trap arm, also referred to as the fixture drain, is the pipe between the trap and the vent. This distance depends on your local plumbing code. If you’re in the IPC, there is no limitation in length for the toilet’s trap arm. That’s right, no limitation!

So those in UPC jurisdictions, simply make sure this distance is 6 feet or less (Footnote 2 of Table 1002.2). Additionally, if you plumb your toilet with a 4 inch toilet drain (which isn’t usually necessary), the UPC still limits the trap to vent distance to 6 feet.
How do you install a vent under a toilet?
Use a reducing wye to transition from a 3- or 4-inch drain line to a 2-inch vent and direct the sweep of the wye fitting toward the sewer. Connect the Vent Underneath the Toilet: If the toilet waste pipe drops vertically to a long-sweep elbow, you can install the vent in the vertical pipe before the fitting.
Why does a vent need to be in a toilet?
In short, the toilet wouldn’t work. The vent allows air into the waste pipes to equalize the pressure, which keeps everything flowing and prevents the trap from emptying. The plumbing and building codes have requirements for pipe size and placement to ensure that enough air gets in and that it goes to the right places.
