7/2/19 – Park Tool PFP-4 (floor pump) malfunctions
7/3 (4:34 AM) – Email Park tool: “When I use on a Schrader valve, air comes out of the presta valve opening. Thus, no inflation takes place. What part do I need?”
7/3 (9:31 AM) – Email from Park Tool (St. Paul is a bit behind time-zone wise): “Hi —– It sounds like an issue in the head of the pump. We will send a replacement head. Thanks. Dan”
7/3 (2:29 PM) – Email from Park Tool with shipping notice for 3-day delivery.
7/8 – Not only the new head but complete head and hose arrive.
7/11 – Switch head and hose – 30-45 seconds. Problem solved.

While the PFP-4 was laid up, the 1971 Schwinn pump came out of semi-retirement after continuous use from 1971-2007. This came from Klarsfeld Cycles – now CK Cycles – https://ckcycles.com/ . Charles Klarsfeld, “CK,” founded the business in 1905.
