I have been test running my mag 3 I bought from MarineDepot for the last 3 days. (I was busy doing other things so I just let it run; making sure to get any air etc.)
It died today. No extra heat, no weird sounds, just quit. I added a couple of drops of anti-algae solution from my pool kit this morning. It first clouded then cleared up.
About 30 min (?) later I walked by and noticed it was foaming in the T-line pretty bad.
There was a small amount of air in the line (heater core), but the pump definitely was primed from the beginning to the end. I find it hard to believe that it was a failure due to any miniscule air bubbles trapped somewhere.
So I guess since I am passed the point of return on the watercooling adventure, I'm now looking at pumps - again. My next pump will probably be something different.
Off topic but -
I also noticed that after install;
With clearflex 60 1/2"id tubing & black "DD type" plastic hose clamps (where applicable)
black 1/2" nylon fittings - without clamps - near impossible to remove hose. I think you would break a fitting before the hose would come off these barbs...
black 5/8" nylon fittings on pump - without clamps - near impossible to install, will probably have to cut all the hoses off any nylon fittings...
Brass 1/2" DD barbs included on my Maze 4 GPU, easy to install, w/ clamps snug.
Chrome barbs on RBX (requested brass
) easy to install, easy to remove. With clamps, snug but a good tug they can turn.
**Hoses heated by pump only after 24+ hours**
Brass barbs easy to remove hose unless clamps are _tight_.
Chrome barbs are either leaking or have moisture forming past all the clamps. *granted, the clamps weren't extremely tight at that point
I would say imo, even after tightening the plastic clamps w/ pliers you could pull a hose off the chrome barbs if you wanted w/o too much effort.
The nylon fittings? Forget it. I know I will be cutting them off.
