Query: Tube breaks and leaks at nozzle attachment.

With braces on my teeth, I needed some way to dislodge food that would stick between the wires. I bought this model.It's loud (I wore earplugs) but it served the purpose, UNTil the tube sprung a leak at the base of its permanent attachment to the nozzle piece. I had not used it that long, and did not think I'd been rough on it.I tried to pull the tube out to recut and reattach, but couldn't. I foolishly bought a 2nd water pic. I tried to be more conscientious about the way I held the nozzle, and even strapped a tape around the area of attachment. But the 2nd one also sprung a leak in the same place after some months of (less than daily) use.
