[VAC] Re: Plumbing vent

["Scott Scheuermann" <s.l.scheuermann@xxxxxxxxxxxxxxxx>]

Dave, if those valves ever let air through the plumbing back into the
trailer, you will not want ANY of these valves. While at a campground you
(or the next owner) will undoubtly hook up to sewer. You may be letting
everyone else's sewer gasses into YOUR trailer. Much better, though
asthetically unpleasing is to have a vent sticking out the top of the
trailer where the odors can diffuse.
