Kpar As well as Kevin s have a good look at your channel pour some water into it with the rubber out the upper channel should catch any that gets past the rubber if it should fill up then any spill over should be cort by the secondary lower channel and feed out the drain tube ,Lower one is often rusted , the Ones I have fitted I glue the flat side to the lid the lower part seams to fit the channel ,not sure if its right
