Fixed our problem
Quality product and brand. Previously, we purchased a off brand, cheaper vent from our local hardware. That valve only worked 50% and for 6 months. This valve immediately allowed the proper air flow which resulted in drain emptying. Easy installation.

Not need to cut a hole in your roof anymore. Never smelled anything in the past 2 years since the installation.

Doesn't work in rv
Failed less then a month in service. I am out of the return window and no response from seller since it is fulfilled by Amazon. Thought the more expensive one would be better. Save yourself headache and choose another brand.
