Tiny, tough, LONG LIFE... 12 years!

Ok.. this little guy has lived through 2, yes TWO , Honda engines (Yes they were properly maintained, gc160 died, moved to Gx200)! 12 years ago! It has been left hooked up to a garden hose nearly constantly, outside 100% of the time, accidentally frozen at least five times, has outlived two other triplex style pumps, (one triplex died and donated its Gx200!) I have literally been baffled by the durability of this pump... It may not be the most GPM or the highest pressure.. but it is an absolute beast, almost indestructible! The amazing part? Towards the end of its life, unbeknownst to me, it developed a pressure-side water leak towards the sealed oil case side.. at some time during the last year all of the oil was replaced with water... The dang thing ran with water as lubricant instead of oil for what I'm guessing is the better part of this last year.... UNREAL Lol! The only way I ended up knowing this was due to the growling of the bearings... IT WAS STILL WASHING WHEN I TOOK IT APART! ABSOLUTELY BUY THIS! TAKE BETTER CARE OF IT THAN I DID AND THERE IS NO TELLING HOW LONG IT WILL LAST! And to the engineer who designed this product... Be proud, you've made something that truly makes people's lives easier!
