They are designed to block sewer gases in DWV systems by opening and closing when the slightest change in pressure is detected. Available with PVC or ABS adapters, this Sure-Vent air admittance valve vents up to 160 DFU (branch) or 24 DFU (stack) and fit 1-1/2 in.–2 in. pipes.

Review: Quality - It woks as it should, very pleased with the quality and price
Review: Works without any modification w/ 2" pipe, works with adapter w/ 1 1/2" pipe - The threads on the actual automatic vent unit are 2" male. The included ABS adapter has 2" female threads on one end and a 2" female slip joint on the other end. If your vent pipe is 2", the included ABS adapter will glue directly on to your 2" ABS vent pipe. If your vent pipe is 1 1/2" ABS, you will need to purchase an additional ABS adapter at your local home improvement store to reduce the diameter from 2" down to 1 1/2". Installation is straight forward. Make sure you use Teflon type tape on the threads of the automatic vent to completely seal off any sewer gasses. I like that the automatic vent is threaded (not solvent welded) to allow for easy removal if the unit requires replacement in the future.

### ⭐⭐⭐⭐⭐ saves vents
*by T***M on December 10, 2024*

Not sure why everyone does not use these - saves vents and roof penetrations. They work great, no sewer gas leakage. Last two new builds I have used as many as I can practically use. Great product.
