Washing machine drain pipe...

[karlsultana8]

Hi,

The washing machine drain pipe goes through a hole in the wall. But there is a gap in the hole. Is it ok to block this gap, with a cloth or something more professional? Because maybe cockroaches can come out of it.

Thank you

That's not right, what if it backs up? How do you know? Open that up and install a box is what a professional will say.
