I prefer ddcs bit frankly I like the micro pumps recently and may have to have some fun with those soon
As for me i have something made that attaches to a water hose that I put on my hot water heater. Put the other side down a drain flush one side then reverse the flow and flush the other direction.
Some use vinegar others lemon juice others water .
I actually (indirectly) started the thing going again.
Asked people about the lifespan of my D5, went on to think about switching to a DDC... Then posted some stuff from a review of the Swiftech mcp50x Geggeg placed a while ago with calculations of my loop restriction (~3psi drop). Then found out that the 50x alone wouldn't even help much compared to my d5 currently. So dual's were needed..... and then the overkill topic started rolling again. Making the Correcting One join in. And then the party was complete.
I've actually also used the tap to hose to rad thing before.
Beware to advice people to do that: don't run high pressure, you may damage the tubes in the radiator.

I seemed to have missed the firefight, narrowly.
I was actually honestly interested and serious.
Made calculations and all and wanted some advice on whether to change my d5 or not.
But I have to agree that the contradiction of "overkill man" was somewhat funny.

What is your criteria for "actually pumps"?
The point where it barely moves water?
I don't have actual data to back this up but I don't think the pump will last longer if set on a lower speed (bearing should last longer theoretically). Like said before, above a certain point the gains will diminish. At some point you will get a very small performance increase (lower delta) but that will be cancelled out by the increased heat dump from the pump using more power.

I did flush new rads with just distilled.
However, I do clean them(periodic) with acid (diluted) to get gunk/dye out.Edited by Chopper1591 - 7/24/16 at 1:17am
