I sent in four more air operated flo-jets this month; under warranty. Made in China, ofcourse. I wish they would bring production back to the US, and charge what they need to charge to make to the pump right. It is getting to be a pain in the a$$ changing these all the time. And ofcourse, it is always a Saturday or Sunday when it gives out. They have been lasting only 8-12 months on my pre-soak and tire cleaner. Yet at one location they are the original units (over 10 years old) made in the US (running same chemicals). I think that says it all.
