Oversizing the drain lines-any problems?

[AZBigJohn]

I am switching my overflows to dursos-the previous owner had these silly foam and plastic bubble silencer things... Using the instructions for dual, one-inch overflows, I used 1 1/4" PVC to create the dual dursos, and, without thinking, bought all the plumbing for the drain lines below the bulkheads in 1 1/4" as well. I can't imagine it would be a problem. There shouldn't be any air to get sucked in there to be an air bubbling problem; can you think of anything else that might rear its ugly head that I am not thinking of before I start gluing?

Thanks for any thoughts!

I don't think it would be any issue at all. Bigger pipes can flow more water. I'm doing 1 1/2" on my new tank.

No issues; you're fine.
