I have a old pressure washer with 1.25 hp Baldor motor. Sold by Northern Hydrulics. Star brand 1500 psi 2.1 gal per min. weighs about 35 lbs. Its one of those things I seldom use and got neglected., and pushed back in corner. ( good stout frame with tube tires) Water was left in pump and busted it. I can't use a gas one because of a dislocated shoulder and broken fingers on other hand. I was searching for a replacement pumb for it (made by General) The pump costs $500. No way am I going to replace it. I have a couple of cheap Roybi washers that just bearley work. ( cheap nylon hoses, gun, flimsey plastic case and cheap parts. I have been looking for a replacement electric washer, I see on on Temui that looks like most of them, (vaccum cleaner style) It lilsts for under $150 and lists 4000 psi with 3.2 gal. (looks about like Ryobi) How can ther make a preassure washer that meet those specs and weight only about 20 lbs. When purchaseing one I would like to get at 3000 psi. Add says it has 3 adjustments for pressure, low, medium and high. Advice, thanks
