Quick question re: bathtub roof exhaust . . .


We have the 2" PVC pipe installed for our new baththub's vent exhaust and it sticks up through the roof, as planned. My question is:

Should there be some kind of little "hood" or "grill" over the top of this PVC roof pipe to keep leaves, mice etc. from getting into the pipe and clogging it . . . or is this just not necessary? Thanks.

Normally not necessary. Does need to be at least 12 inches high (so it doesn't get covered with snow). If you're really concerned about it, you can pick up a push-on cap at most RV dealers.

I've never once seen any form of cap on a sewer vent. Not needed.

I think he meant it for his exhaust fan in the bathroom, and if that is the case, out of curiousity, what stops the exhaust air from condensating and running back into the fan.

Read the original post again. He's talking about the vent for his bathtub, not an exhaust fan.

Actually the OP is rather vague.
He describes a DWV vent but also asks about a bathtub exhaust.
I suspect he MEANS the DWV... but I'm not certain he does.
