I was not aware of these discussions between you and MSA prior to the motors shipping. See email below from Clint. We need to resolve this. Tom Tom Shedek, PMP | Project Manager TRICON CONSTRUCTION GROUP C: 913.238.6689 [email protected] From: Clint Wienen <[email protected]> Sent: Monday, February 23, 2026 3:20 PM To: Tom Shedek <[email protected]> Subject: FW: Tiffin WTP Low Lift Pumps - 0915659 Tom, See correspondence below and attachment. The reason the shop drawings were not returned is b/c the low lift pumps did not meet the specified e2iciency requirements. The shop drawings indicated the pumps were 76% e2icient at the duty point. When they ran the pump tests, the e2iciency was 72%. I asked for an explanation which Z&F provided but that fact remains the pumps do not meet the specification. Based on the pay app., it appears that the pumps have already been delivered to your shop. Please discuss with Z&F to see if they are willing to provide a credit for acceptance. Thanks, 5
