Thanks for your reply! Unfortunately, I have removed the pump from the filtration unit, and the filtration unit from the pool, so I can't photograph it. It's the model from 8 years ago. The pump sits on the floor of the unit, in the part outside the pool, and below the water line. Normally, I lift out the whole lot, then disconnect the pump. I once tried to disconnect it without raising the unit, and the compartment flooded. There are two pipes screwed to the pump, one in and one out, and they screw off easily. There must be a sequence or procedure for unscrewing them without flooding. There is a picture on one of the Desjoyaux sites, but I can't find it!
