How old is the hose? My DME, granted take that for what it is worth, will replace my hose every 3 months "to prevent infections". I have a standard hose so the cost is pretty cheap, less than $10. Might be worth just getting a new one. Not trying to spend your money though.

Using this with W-03 and works just fine. I haven't had the time to look into scripting that runs when a file is written to push to my PC. It's on the list.
