Hi, please help preserve my sanity here! I purchased the 30m Garden Basics hose this weekend and have been attempting to install it into brick. The instructions say to drill 4 x 8mm holes, which I have done but the supplies plugs seems to be far bigger than 8mm (see pic).
I’ve drilled one at 10mm which seems a little better but at this point I’ve broken two masonry drill bits in these extremely hard bricks and want to be 100% sure before I persist.
What do I need to do here? Why are the instructions seemingly at odds with the supplied plugs? And going by the diagram I need washers as well however these were not included in the box - do I need to make a second trip to purchase these separately?
