Help with my Hagen loops please

OK, I'm getting hum when I put any of my delays in the parallel loop ONLY when I run my Decimator II G-String in the series loop... If I only use the Decimator without the delay plugged in, it sounds great..... Also, If I only use the delay and don't hook up the decimator, it's great... My delays in the series loop change my tone significantly, but in the parallel loop sound great... I just can't run both without a ton of hum that the Decimator does not get rid of.... I'm confused.

It was a ground loop. The Decimator pedal didn't play nice with the rest of my shit. The rack has a ground lift but Reza is right. I don't really need it to go and buy one.

ground loop. sort out the power issues first. LOVE my Hagen!

Yeah I've had to use that lift on my rack version with certain pedals and amps.

Or try replacing it with a denominator paired with a numerator.
