we have not decided 100% yet to switch suppliers. i am leaning towards it, but the latest few pumps that shipped out seem to be in working order. i would like if possible to stick with the current supplier and work out my issues with them, but that depends on them.
perhaps i am misreading this, but by using the exact same parts we're using, you're implying our assembly is at fault moreso than the parts themselves. if thats your opinion i have no problem with that, but i would rather you let us know what - if anything - you feel we are doing wrong which would cause these pumps to fail when it is pretty clear that improper machining is the cause. perhaps thats not the message you intended to convey, but it is how i interpreted it.
your help in getting our pump to market was instrumental despite the well advertised drama involved in doing so, and i value your input and help on its continuance. if you would rather do your own with the parts we've been seeing problems with, i have no issue with that or any other kind of competition, just be careful with the parts and people supplying them to you.
