Easy Install. No Way It's 3700 PSI.
Easy install. Doesn't seem to leak oil like the original that came with my simpson ps3228 pump did. I don't have a pressure gauge but I'm more than sure this isn't 3700 psi even with the unloader turned all the way in. My old pump was rated at 3300 and would practically life my surface cleaner off the ground. Had to crank the unloader all the way in to get good pressure to turn the surface cleaner satisfactorily. All in all, not bad. It will get the job done. It's just not 3700 psi. Maybe at best 3200 psi.
