How often do you drain and clean?

post #1 of 10
Thread Starter 
When I first got into WC back in 2009, I would drain and clean everything out about every 6 months. I didn't want anything bad to happen so I took good care of the machine. I'm not arguing against maintenance ... however...

I just tore everything down for the first time since Feb 2013. 32 months operation on the same water. And somewhat to my surprise everything came out super clean. I didn't drink the water .... but I considered it as it looked totally pure. wink.gif The blocks are clean. The rads are clean. All I had in there was distilled and a silver kill coil. No critters and no corrosion to speak of.

So, what's the deal with all those additive products and the supposed need to flush every 6 or 12 months (whatever they say). It seems you can sort of set it and forget it and a lot of that might be overblown. The 3000 mile oil change concept as to WC..

After filling this back up I may not touch it for a very long time again. Maybe even longer. Am I rolling the dice? Anyone have a system running for a very long time on the same water?

I guess I should add, part of the reason I didn't do anything for so long was

A) the system / loop was dead stable. Why mess with it and get a leak or something.

B) I was lazy / otherwise occupied with various things.

C) the res I just removed for good was a nightmare to fill every time. (Old rp452x2 Rev 1).

I've left my system for a similar length of time, maybe slightly longer.

My cpu block is showing some discolouration but nothing serious.

My reason for leaving it so long is pure laziness plus it all looks ok.

Some additives will degrade over time, especially colours.
Plus if you were selling expensive additives would you rather people bought new every 6 months or every 4 years?
To be fair some manufacturers do have longer life I think EK has a 3 year life.

I will be breaking mm loop down soon as I'm building a new case and upgrading to skylake.

Btw my eheim 1250 pump is at least 13 years old and still working great.

Last drain and clean was 2012 for me and before that was 2008. Worst that happened was copper oxidation and some gnarly tube discoloring.

I have the rp452x2 Oo. What was so bad about the fill port? Maybe I have revision 2.0 and it isn't bad, but all I do is unscrew the top fill port, use a big syringe and fill it up. Was there something different with earlier revisions?

Also: I never clean my loop unless it's part of a tear down for an upgrade. And every time I have done it, I didn't feel like I let it go too long - in fact, could easily let it go longer. Last time I seriously drained my loop is when I put in my redundant pump a few years ago.

Edit: Re confirming with myself, I have the RP401x2, but my question still applies. What was the fault that made that res so hard to fill?

Never. I upgrade parts so much nothing lasts longer than 3 months in my loop. biggrin.gif

Like 2 or 3 years ago for me lol, and that's only because I was changing blocks. I don't have time to mess with it, it works good as new, I don't see any particles flowing through and the silver coil is doing its job fine. I never replaced the tubing, it's now 4 years old, never had a leak with compression fittings. When I was a little younger and had more time to fiddle with stuff all the time, I would have probably done it a lot more often but now I only do it every couple years when components get replaced.

Just did mine after almost a year. Decently clean system when I drained it, just a few particles swimming around in there. Didn't break anything down, just ran some old cleaner from Primochill I had laying around for 16 hrs. Probably did nothing but I was doing a color change so I gave it a shot. I just put white pastel in so as long as it stays white I'll probably just let it be.

On a side note I thought I would hate just the plain white coolant. Came to find out that with RGB case lighting you aren't limited to certain color schemes (duh) so the white is playing to my advantage. I'm loving that.

Alright, thanks guys, nice to hear I am not the only one letting things sit for long periods of time. I also "got old" and just am not into it as I once was. It's came back a little bit recently. But I fully intend to get this stable again and never do a clean and flush for preventative maintenance as I used to.

The rp401 is a totally different animal. The rp452x2 is the bigger one that there are now 2 (or even 3?) revisions of. The older ones (the one I struggled with), the pumps pinch in from the sides and koolance pretty much botched the design of the internal flow cavities so it's a real PITA to fill and bleed. The way I have the loop laid out with the rads on the top doesn't help either. It's seriously a 2-4 hour ordeal full of tipping, sweating, and swearing to fill it up. (Yes I've tried all this and that to help, I know what I'm doing). The thing doesn't bleed....

So they've remade the rp452x2 where the pumps sit side by side and downwards, they also redid the inner cavity bits and it's supposed to be a little easier to bleed. I have that one in the mail so we'll see how it goes. Bleeding aside it's a nice unit. If the bleeding is fixed it's a GREAT unit.
