12 months ago I bought and Island inflatable electric kite pump from Kitepower. It has been great for the last 12 months. Just after 12 months the pump failed to switch from low pressure pump to high pressure pump. I opened it up and discovered the switch mechanism was a simple spring. The spring had lost it's tension after 12 months use. I shortened the spring by looping more of it over one of its anchor points. This solved the problem temporarily. I would like to get some replacement springs. The rest of the parts seem quite sophisticated and it is strange that a $300 pump can be rendered useless by the failure of a 10 cent spring. Any one know where I can get replacement springs?
