Can you vent a toilet with a Studor vent? ›

The Studor vent lets that air to be sucked in the pipe during water flow but doesn't let sewer gas escape out. Code is the thing that determines pipe size and also water flow. Hence no studor vents are permitted to toilets because more air is required to keep water flow going with more waste added to the toilet.

Air admittance valves have a typical life expectancy of 20-30 years, so if you start to have issues with sewer gases or smells being released around your sink or in the attic-wherever installed- the air admittance valve could be faulty or failed and should be replaced as soon as possible.

The Studor Air Admittance Valve (AAV) is a one-way valve that allows air to enter the plumbing drainage system when fixtures discharge.

Yes, the toilet and sink can share the same vent, as can the shower.

Poorly-vented drain lines will not be able to effectively move wastewater and solid waste out of your building. This could lead to problems such as overflowing drains, backed-up toilets, and similar plumbing issues.

The main problem with using an Air Admittance Valve instead of a Soil Vent Pipe, as discussed earlier, is that by preventing the gases from escaping through the top of the soil stack you are causing them to be forced down into the main drains and sewer system instead.

The Studor valve must be installed a minimum of 4" above the horizontal branch the horizontal branch drain or fixture drain being vented. Studor AAVs must be installed within 15 degrees of the vertical position. Studor valves can be installed below the flood rim level of the fixture.

To see if the AAV is working properly, take the valve off and shake - if you shake hard enough you should hear the diaphragm rattling. If you hear no noise the AAV may have failed. Additionally, smelling sewer gas is another sign that the AAV has failed in the open position.

It must be located a minimum of 4” above the horizontal branch drain, 6” above any insulation material and within 15 degrees of vertical.

Does a Studor vent go before or after the P trap? ›

Air admittance valves are typically placed between the P-trap of a fixture and the drain line. They're usually mounted on one leg of a sanitary tee, with the other leg going to the drain. The unit must be placed per local codes and the manufacturer's instructions.

STUDOR AAVs must be installed in the vertical, upright position. A maximum deviation (in either direction) of 15 degrees is allowed. The vent shall connect to the drain vertically to maintain an unobstructed opening in the piping to the STUDOR AAVs.

NO. The toilet uses the main stack of the building. If you blocked off the main stack any poisonous sewer gases could force back through the various water traps in the building including the toilet, so my contention is you must have a main stack.

AAVs are a great alternative if you can't connect to an existing venting system due to complex pipe routing issues or obstructions – an ideal venting solution for island sinks, remote bathroom groups, home remodels and additions that would otherwise have to be tied into a stack vent utilizing specialized venting ...

Behind or within the Wall: In most cases, the vent pipe for a toilet should run vertically from the toilet's waste pipe (known as the closet bend) and extend upward to connect with the main vent stack or a branch vent line that ultimately exits through the roof of your home.

The fixture cannot drain effectively if there are no vent pipes connected to them. For example, in a bathroom fixture group, if you flush the toilet and there is no vent to that toilet, or the vent is not working properly, it may suck the water out of the trap on the bathtub.
