I made a mod to mine and it was really straightforward. If you look at the collection cup lid there is a small hole with a plastic cross within it, I removed this and attached some airline pipe to the nipple on the inlet pipe and the other end would go through the hole in the collection cup lid. If the cup ever gets too full and reaches the air pipe then the bubbles cut out. Nice and simple and stops any chance of it overflowing.
