Fear not, this is not a medical post but is related to my pesky sliding window leak. A topic done to death I know. I’ve had a good look round the forum and I’m pretty sure this isn’t right.. but would appreciate confirmation. I’ve poked a cable tie down the front drain hole slot and shown in the photo how far down I can get it… so not all the way down so it comes out of the bottom (ooh er)… does this mean I have a blockage?
