Hello everyone,
We moved into a house that recently had a leaky tap, and I want to check that the water hasn't leaked below the laundry trough cupboard, but I don't know how to open the floor panel pictured below.
First picture is of the "screw" which doesn't really have any groves and thus match anything I have in my toolbox and the second is a view of the entire panel I want to remove and check / clean under. Sorry this is way out of my expertise and I hope it doesn't sound stilly, but if anyone can help me with where to start that would be fab 🙂
