Default Cap for plumbing stack

Nexus7 wrote:

The plumbing stack sticks out 2' from my roof. It is a 4" iron pipe (OD
is 4.66"). That's all there is, just the pipe sticking out. What kind
of cap, if any, is appropriate for it? I can get a cap that is made for
appliance vents and is adjustable for 3-5" diameter. However this is
designed with an upward flow of combustion gases in mind. Thanks.


As others have noted, no cover is the norm, however after retrieving a
drowned squirrel that was blocking my drain line I capped my vents. All
I did was cut oversized squares of aluminum window screen, fold them
over the top and down the side of the vent pipe and secure them with
stainless hose clamps. No more risk of squirrels or anything else
falling down the vent.
