Okay so I'm sure there's another post similar to this but I ran a quick leak test on my new build last night for a few hours however I've got 2 ek 18w ddc in my loop an I can't believe how noises they are whining etc, they arnt bolted to anything only the flexible pipe that attaches to them so it's not a viabration sound, I have today order 2 EK d5 vario crop pumps to replace them, is this the better option? Appreciate your comments cheers
