Cover for plumbing vents

Posted by canicci (My Page) on

Our neighbour saw a rat going in one of the pipes sticking out from our roof...Ewwwww.

We checked and there are no holes around the pipe. None of the vents have a cover. I would like to put covers on the vents. I saw some plastic covers, but they can't be used on gas exhaust. One bathroom is beside the furnace/AC/Water Heater location. There are 6 pipes there - I think one each for toilet/2 sinks/bath tub ?? The other 2 might be for the furnace. How do I know which pipes are plumbing vents? Silly question, but I have no idea.

Should I use a plastic cover or just clamp wire mesh over the vents?

Thanks for any help.

I would treat the local rat problems and not worry about the vents.

RE: Cover for plumbing vents

Depending on where you live, covers on plumbing vents can be problematic. If you live more in the northern US, covers can frost up in the winter. Plumbing vents typically are uncovered. You can use 1/8" x 1/8" galvanized wire mesh over heating vents and intakes. I would probably place rat poison around.

Take Care,
