Review on Enhanced Performance: Introducing the 1-1/2 inch Tuuber Vent 2x Superior Seal Air Admittance Valve by Oliver Waiker

I tried another brand and it didn't work for me. I have a septic tank that is not connected to a municipal septic tank. I also live in a trailer. When I tip the tanks onto the van, a large amount of waste water is immediately poured into the system. This amount of liquid displaces a lot of air in the tank. When using a different brand of valve, the pressure was high enough that the other valve had little to no resistance to the gases being expelled, forcing septic gases through the valve into the room. Thanks to the Tuuber valve, it is resistant to dynamic pressure and thus prevents pressurized sewage gases from entering the room. This valve worked perfectly.
