If you wanted to get fancy you can order you a plastic welding kit from Harbor Freight or some other outfit and it would probably work if you could find the crack but I think it would be a much cheaper and less time consuming just to replace the water chamber!! LOL!

Yeah that works also at times, but when all eyes are in your mouth you have to create a bit more motion sometimes to get their attention!

I have a hard time breathing out my nose when my mouth is open, and then they got there hands and tools in there and filling the back of your throat with water and I have to start kicking my legs to get their attention to call for a time out every once in a while to breath and keep from drowning! LOL!

AYR saline nasal gel works for me!
