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?

thanks

Steve,
On my Eheim 2026 i tried to use the primer...got it to work once (filled the canister and tubes from the tank so all i had to do was plug it in). Otherwise i spent a lot time fussing with it (push it fast...push it slow...move the tubes this way and that...i felt like i was trying to pull in a tv station with an old fashioned antenna). So now when i clean the filter i fill it with water, add dechlorine, add media and snap on the top with it full of water (do this in a sink or tub since you will have overflow). Then when i attach the tubes and plug it in it is off and running. My tubes stay full of water during this process since i have no need to remove the water from them. I sometimes give the primer a push to dislodge air...but don't rely on it. Be careful not to run your canister with air trapped at the top or you run the risk of burning out the motor.
Good luck

thanks. how would i know if air is trapped at top? is it a good idea to gently rock the canister side to side to dislodge any bubbles?

when I start my 2126 (when a full canister & tubes) I get a quick, slight thwack of something kicking into gear (maybe the impellor hitting the impellor walls and stabilizing), but then all is fine and quiet. Do you get this, too, when you first plug it in after cleanings, etc?
thanks!

I also fill my 2128 to the brim, hook it up, and then violently press down on the priming "button" and allow it to come up by itself. I then repeat as soon as the button has come up and repeat again until the pump stops making any noise whatsoever. A properly running Eheim is silent.

I have a 2028 and priming is a bear. I had to have my husband do the initial prime--once the tubes are filled with water, it's not an issue for me. I just make sure to fill the canister after maintenance.

I do have one recommendation--make sure you have an extra gasket seal on hand. I recently moved and had to break down my set-up. I just reconnected the filter, made sure everything was fitted properly and there were no leaks. I came down the next morning to find my 2028 pouring water out of the back (where the pump head meets the cannister)--it was the gasket. I luckily found one lfs that had an extra one in stock. The owner said he has had a rash of Professional II gaskets go bad, so he keeps a few on hand.

That being said, I love the filter. I've had many different canisters over the years and this has been my favorite.

When I first installed my 2028 I could not get it to prime no matter how many times I pushed that #%^$ button! Finally I disconnected the pipes and took the cannister to the sink to fill it with water, thinking that it would help start the prime. What it did do was show me that the gasket wasn't seated properly as water began running out between the lid and body. Took the thing apart, removed the o-ring, re-greased and reseated it, then put it all together again. After reconnecting the tubes it primed in two pushes of the button.

I love those installation sets. I actually use them on my non-priming 2228 and 2226. They are great. You simply close the outlet and inlet valve. You open the valve at the top of the intake and put a tube full of water in it. Close the valve at the top of the intake, then reopen both the outlet and inlet valve on the filter. This starts a siphon (hopefully I did not miss a step).
