I've got a skimmer door that occasionally gets stuck in too far forward (in the direction of the pool). It seems that there's some tile on the side of the weir door inlet hanging over a little too far (we just got a new tile a replaster recently). Is it ok to file the tile edge down a bit? And if it is ok to file it, should I be woried about the dust, or will is it ok to assume it will just go into the filter and get cleaned out?
To illustrate, I've attached a picture of the weir door below. It's a bit hard to see, but the edge I would file is in the red box.
