Loop maintenance / draining?

post #1 of 25
Thread Starter 
Ive got my first loop setup, but i plan to add the GPU and another rad a little later, so i would need to drain the loop. Ive got no idea how i would drain the loop though, my other question is, what maintenance would i need to do / how often?
Thanks thumb.gif

basically once every year or so, drain, clean blocks, reassemble, replace any tubing you feel necessary.

far as draning, remove the pipe from a barb at the lowest point in your loop, and have a pot to catch the water.

Alright that is pretty much what i thought. Now when i remove the tubing from the lowest point... should i run the pump to pump all that water out? or will gravity sorta just do its thing?

You can open it at the lowest point and than open another point in the loop to force air... you can just take the cap off the res that works also.

I would hesitate to suggest a time period for a drain / refill as it is really dependant on your loop as to when you need to do it. Many factors, like the cleanliness of the components, purity of the water, duty cycle and any additives can affect the conditions of the loop.

I would say check it every so often (up to you, I have a quick look every few months at most) and see what is happening. Things you are looking for are any changes in the colour of the coolant or tubing, any floaters in the res or any change in performance. I personally only strip my loop down when I am changing things, I see any of the indicators I just mentioned or I am really bored. Other than that it is possible to run a loop for years without draining.

When you do drain the loop do not run the pump. It it too easy to run it dry, and at most it will safe a few minutes. I actually blow into my fill line to clear some of the water out, but otherwise gravity is your friend here.

I would suggest having drain valve at the lowest point of you loop, in that case you won't spill any water and draining it will be very simple task

My first WC setup was a pain to drain. When I reworked it, I put in simple quick-disconnect fittings so next time I just unplugged one. Blow in one end, put pan under the other.

With my current setup, I included a drain (ball valve on a short hose) at the bottom. Taking the fill cap off lets air in so it does in fact drain.

I think next time i drain it i will probably add quick disconnects or a drain valve... any suggestions for how to do either?

it all depends on your loop, mine has T connector and quick disconnect, here is a pic to give you an idea:
