As a comparison of your units life span to a standard Gast Rotary vane, the rotary vane in my applications have been running for the same run times as yours but twice the depth (14'-15') for 15-17 yrs currently on the first set of vanes. Pump should last for 3 sets of vanes. There is a reason the EcoPlus 7 sells for less $. You got good value for the dollar if you can get 5 yrs on your linear compressor.
Hey Bill,
That's what I figure. I never said it was the best pump out there for sure, but for the money it's works pretty darn good. And if it last 5 years for 105 bucks I'll take that ever day!! We shall see. I will let everyone know if and when it stops working. I know AP has had one for a few years now that he runs all winter long and his is still running strong.
Later,
