Hey Jeremy, I purchased a 1st gen IN-100 from ya'll back in Dec. and it's been doin awesome, but it has gotten really noisy lately and i'm afraid it's the impellar or the pump- what would you recommend? I'm not fishing for free-bies, just want to plan for the future- and if need be replace the pump or impellar whatever you recommend. Thanks for your time
Have you cleaned out the venturi where the air line hooks up to the pump? A lot of times noise is created from the unit by having the venturi slightly restricted (plugged) with calcium carbonate.
Thanks,
Jeremy
