A) My Turnaround time is under a week, but usually just a few days..

B) I do not need cores because fix them down to component level, and I suggest rebuilding the original as four different physical flavors exist with nine software versions, so it is important to use the original.

C) Three year warranty is excessive as someone can destroy the pump in a few months for a leak, $120 USD fix is low cost and replace the motors, replace relays if necessary, repair the board, clean contact, fix broken nipples, and etc..I can offer a few month warranty.. Typically the pump last five to ten years...

All the best,

Martin
