Its a john blue pump it is a nice machine. I used a john blue its a well made pump that performs as advertised. I wouldn't use the hose that comes with it'
It will put out 4gpm @ 300psi and shoot about 40+ ft.The pumps are built right and made to last.Like any other pump rinse it out at the end of teh day and you won't have issues.Rebuild kits are $180ish.
Mel Everett in Vero beach ran the R&D pump for JB over a year without rinsing before he had to rebuild.So holding up to the love isn't as big of an issue as some would think.
