I'm not liking the Harvest Right warranty, right up front, for such a pricey piece of equipment.
Is there a webpage where you downloaded the parts list from Harvest Right?
If you direct me to the correct places, I can post pictures for you from their website and elsewhere, that may help us diagnose and solve your issue.
Harvest Right’s website has the parts list. I have downloaded that but most parts websites want a manufacturer or a model number. The pump has none of that and Harvest Right won’t tell me anything.
