How does priming work on the 2126 (or like models for that matter)?
I hooked up my 2126 with an inline Reactor 1000 on the output of the 2126. I also used Eheim's Installation Sets 1 & 2 for the intake and outflow pipes.
I pressed down the 2126 Primer button. It presses down with some resistance and springs back fast (is this correct)? A little water seems to be sucked into the intake AND outflow pipes. And that's it. I do the same thing a few more times... always seeming to pull in a little water from both pipes.
So what is priming suppose to do? Is it designed to fill the canister? OR, is priming meant to fill the intake tube with a solid column of water that starts a siphon, which flows water down into the canister and out into the outflow pipe (then plug the thing in)?
I know priming can vary for folks ... depending on how far filter is to ground, length & twists in tubing, etc. I know I have one rollercoaster loop in my intake tube! (the culprit?) I wound up just removingthe caps on the installation sets and pouring water down them to fill the canister and tubes. But, in the future, if I have an empty canister and tubes again, I'd like to know what I'm actually trying to accomplish with priming: is it filling the intake to start a siphon (like my old gravel vaccum) or pressing priming over and over again until the dribbles fill the canister? If it's about starting a siphon for the intake, why did my suction keep dying, only resulting in a few gulps of water pulled into the tube? Why is water coming into the outflow tube, too?
