I have just ordered my first custom loop with a CR120 reservior combo and a hercules (V2??) pump inside and very satisified how well it performed. however I just found that industry standard like the D5 pump is rated for 50k+ hours of MBTF and the hercules and other bitspower pumps are only rated at less than 1/3 at 15k hours, which equates to only 1.7 years of 24/7 use. May I ask if that's just bitspower's rating varification process only tops out at 15k hours or it is indeed designed to last that much less than a D5?
