Got a new replacement pump sent to me with the help of April and Hany at FlowZone. Helped me figure out the issues and quickly sent me a new pump via UPS.. Fast and furious - what can I say.. up and running now and all is A OK.

Perfect Warranty Replacement
I received this one as a warranty replacement. Wired it, plumbed it, put it all back together, and back in business.
Thanks, Flowzone

Flow Zone Pump
This company is great to work with! We bought a backpack sprayer that apparently had a faulty pump and they replaced it quickly and with little effort from us. Thanks Flow Zone!
