I was getting tires at Discount Tire and struck up a conversation with a plumber (he was getting tires for his van). I asked him what he thought about Pex and installing it in an attic. He expressed concern about mice and rats eating into it.

Is this a legitimate concern?

What do you think of "sleeving" Pex with something like electrical conduit (for the large radius bends) where this could be an issue?

I've fixed one mouse cut in PEX. It was an old farm house. It happens.

I have it on good authority (from a mouse I know) that if you give them more palatable stuff to chew on, they'll leave the Pex alone. :whistling:

Go ahead and run it in the attick if its conditioned space (or it doesn't freeze in your area). Mostly mice will try to get from room to room by chewing pex to get to the hole in the wall.

I have had to make several repairs were mice have chewed through pex, apparently they chew it so they can get past and through the same hole and not because they like eating it particularly.

If you are going to go the expense of sleeving it wouldn't running rodent proof pipe make more sense?

I have seen rodent activity on PEX pipes, dishwasher drain hoses, dishwasher supply lines, and washer pressure hoses.

So yes they will crew through PEX pipe with relative ease.
