Well OK then, next week I shall get on the roof and install a drain insert on top of my PVC vent. Anyone know the dimensions of the PVC? 2", 3" ??? The slots in the drain insert are very similar to the ones used in shower enclosures and will prevent any critter larger than the slots to enter. I can deal with anything smaller than a drain slot :

Handie :joke:
