Great product
Eliminated the need for the vent stack through the roof. Since my roof leaked at the vent stack I decided to cut stack down to attic level and have the roofers re-roof and delete stack exposure. Works perfectly.

Best product to keep sewer gas out.. install takes seconds
The product is amazing it has a rubber gasket attached to it that fits over a 3-inch pipe or slides into a 4-inch pipe. I had a different brand put on last year when there was a lot of pressure it released a gas smell. And the other one went bad and I could not get the gas smell out of my basement that's sewer gas. I put this on yesterday came down this morning to the basement it smells fresh and clean with no sewer gas. I am excited to have this product well worth the money. I have attached the studor photo... and the competitors that does not work
