Kind of boring actually..in a very good way, i.e., there were no surprises, no mods to be done, and therefore, no memorable moments of blood, sweat, n tears drama involved. Cranked right up in synch with my existing Honda GX390. This pump replaced my General Pump TX 1510A which in comparison appeared to be superior in quality to this pump and I believe more expensive. Firstly, there's an obvious size and weight difference (if that means anything), where the General was larger and heavier, and also, the quality of the unloader on the General Pump which I know 1st hand down to the packing washer was a much more involved build when taken apart, but perhaps thats why it gave me so much grief, was so temperamental and unforgiving, and practically killed and nearly took down the Honda engine with it before it failed and blew the pump's crankcase open. Anyhow, lesson #1, don't rely on the unloader during downtime, just turn off the engine! So, its not the same pump as the General with all brass parts and with a much more substantial unloader probably reflected in the stats but you know what I don't care, I'm up and running, the price is right, it works great, and seems to be not as temperamental when it goes into recirc mode (trigger release downtime). It definitely seems gentler on the honda engine when placed in recirc mode, where with the General both pump and engine went audibly and visibly ballistic when there was any downtime or decrease in water flow which needed a quick adjustment in water flow. Point being, this leads me to think that the power output is perhaps nowhere near what the General engine put out but I'm unable to verify this. That would require a side to side comparison using same power setting dialed in using each pump's respective unloader. The one application where I likely need that extra power up front is jetting a difficult residential sewer line clog from inside the house without the fear of it backwashing into the workspace (the kitchen) which it did using this pump. But in all fairness, that couldve happened with the general too, I don't know, noone told me about that catastrophic possibility and how to prevent it from happening. Brutal experience. I'll throw that in, pressure jetting is not a cure-all or direct replacement for the sewer snake unless you have an astronomical psi at your disposal like the city trucks do. Snake then jet. For those of you doing a ground up install, this did not come with any bolts nor the easy-to-lose little metal axle rectangular slot key that marries engine to pump. Also, to alleviate concer, the shape of the bell housing (chambered area around the axle) where it interfaces directly to the engine and bolts on was different in that it was more of a trapezoidal shape unlike the square shape bolt pattern found on the General but universal fit it was and all the right holes lined up with no issues. It does have its own built in inline venturi soap dispensing inlet (post-unloader valve) but, it did NOT come with a thermal relief valve which has so far seemed useless to me anyway, as it never was utilized/engaged/popped-off while I watched the General crankcase explode while the engine kept running freeing itself of the shackles (gotta love the Honda). But the pump's relief valve definitely showed no signs of relief as I would have expected the high temps generated during this dramatic jaw-dropping, and wand-dropping moment to produce some sort of visible steam/water/or gasping of both out of the temp relief valve, but nada. I've read that its a desperate too little, too late, last-cigarette, last resort valve. Nonetheless I xplanted it from the general to this pump with perfect fit. The in/out fittings on this pump might need modifying depending on your existing accessories. I like to make my in and out fittings all male, which at the cost of convenience is my insurance and way of idiot proofing the pump from the possible trapped air or water after finishing up, therefore allowing the pump to burp and bleed out whenever it wants to, on its own terms, eliminating standing water and theoretically preventing airlock from happening hopefully allowing for a trouble free startup the next time i hand crank the engine using the pull. Lastly, the oil level indicator is not as cool looking or as easy to read as on the general but keeps me vigilant with a closer eye as I have to do a double take on that very crucial oil level. As for the longevity of this pump I can't answer that but all in all, up to now its been a great replacement pump. Review: Easy to install and came pre-loaded with pump oil! - Replaced my old water pressure pump from my Honda GX340 pressure washer. They both had a 1” shaft diameter which is an important bit of info to know when changing out your pump. The only inconvenience was that the unloader valve came separate so that had to be installed. No biggie. I’ll update if anything changes but so far so good, gave it a test run today and works great. ## Features - COMMERCIAL-GRADE PERFORMANCE: Heavy-duty triplex plunger pump delivers smoother operation, higher durability and higher efficiency than axial pumps, ensuring long-lasting, consistent pressure for residential and commercial cleaning applications - ENGINE COMPATIBILITY: Standard SAE J609-A mounting flange fits most 13 hp (390cc class) direct-drive horizontal-shaft gasoline engines with 1″ shafts, including Honda GX390, GX340, Briggs & Stratton, Generac, DeWalt, Simpson, Blackmax, Troy-Bilt, Craftsman, Ridgid, PowerStroke, Campbell Hausfeld and Excell models.
