## Description

Product Description The Studor Maxi-Vent Air Admittance Valve (AAV) is an accepted alternative to replace all forms of conventional stack venting, utilizing active air pressure control, allowing the air to enter the system at the point of need. The Maxi-Vent admits air under condition of reduced pressure in the discharge pipes and prevent water seals in traps from being drawn; thus contributing to the ventilation of the main drain to which the discharge stacks incorporating the Maxi-Vent are connected. Fits 3- or 4-inch connections. Dimensions: 5.25-inch vent height x 4.875-inch vent diameter. Rubber construction with a temperature Rating of -40 to 150 deg F. From the Manufacturer This advanced AAV protects the trap seals in the drainage system by allowing the intake of air, so a soil pipe can maintain the right level of pressure within the drainage system.

## Questions & Answers

**Q: does the unit come with the rubber connector? It does not show in the photos and no mention in the description.**
A: The Studor Maxi-Vent I purchased did come with a heavy rubber "adapter" for 4" ( 4"OD) fits hub or coupling. The unit itself is 3" OD, fits 3" hub or coupling. I have used many mini vents and this one works as well or better.

**Q: I want to install it under a wooden deck over a flat roof. How much height is the minimum required to install it?**
A: Carlos , I can't measure the vent as it was installed at a vacation home, but if I remember correctly the vent itself is at least 6", top to bottom, and then add any other fittings , pipe , etc. Sorry I could not be more precise. I used it in the crawl space and with a 3" elbow in a horizontal pipe ,it took up about 13". Carlos, just estimating here, so use your judgment on your project. Good luck! PS the vent works as advertised!!

**Q: Does it come with a donut (or wide o-ring) for connecting to inside of 4" pipe? Female for the vent, male for the pipe?**
A: No. If I remember correctly. I used a 3 inch fernco coupling t connect it to the pipe. 
It is same O.D. as 3 inch pvc.

**Q: Does it require any unclipping or adjusting before you install or just put it up?**
A: It slips right onto the end of your PVC pipe. No adjusting.  I removed my old one and slipped this one on in it's place.

### ⭐⭐⭐⭐⭐ works the best
*by M***Z on January 21, 2024*

i was having an issue with a basement bathroom with a rear eject toilet connected to an ejector pump. the bowl did not empty on one flush, needed several attempts. i located the issue to being not enough air coming in when flushed, since when the standard air admittance valve was removed from the riser it flushed well. i replaced the two riser vent pipe standard air valves with these and it works perfectly now. more air is coming in to allow a full flush. i highly recommend the product.
