I noticed a page within your site which claims that the Medtronic pump is waterproof to IPX7 link: http://www.diabetes.co.uk/insulin-pumps/waterproof-insulin-pumps.html Where did you get this information from? I only ask as it is entirely false. The Medtronic insulin pump is not a submersible unit. We have lost two units now due to accidental submersion, the most recent of which was in only 2ft of water for 2 minutes! This latest incident resulted in my son being administered too much insulin by the (apparently functional) pump, meaning a desperate midnight fight to regain control of his sugar! Medtronic's technical support team advised us that anything more than a slight bit of moisture (caught in a little bit of rain) is likely to damage the pump, causing potential malfunctions!
