|In response to Re: What are these called????????|
It is called an air admittance valve. One brand is Studor. They are not a panacea, since in certain situations they can prevent the sink from draining.
: I want to install one of those valves to let air into my plumbing system so I do not have to run a stink pipe all the way through the roof. I saw one used on This Old House. Let me know so I know what to ask for at the store. Thanks
