I ran a DC10 for about 15 months & the power supply failed on me 2 weeks ago. I had no backup & needed a pump immediately so i quickly bought another DC10 ... (Turns out my old one just needed a new power supply) The NEW DC10 came with a new controller which I hated as well as a nicer looking power supply made from aluminium vs. plastic & it got VERY HOT... I put a laser on it and it was running at 130 degrees. Ii had to run it 100% to get the 14 feet of head from my basement to display... The new power supply quickly started heating up my sump closet & was making me nervous so i ordered the Ecotech M1 ... The M1 is noticeably smaller (maybe 25%) & puts out more water into my display at the same head... I also only have to run the M1 at 80% to get the same results i was getting with the DC10 ... The power supply gets WARM, but nothing like the DC10 power supply... I will likely order another power supply for the DC10 to keep as a backup, but for now, Ecotech M1 is the clear winner for me in my system. Not knocking the DeepWater DC10 in any way & I am not going to pretend to know anything about electricity, but it was freaking me out that the power supply was so darn hot.
