Drain line

Tackle_Berry · 25 Mar 2013 at 14:16

Hi,

Thinking about putting in a drain like this, so basically I can just undo the stop cap underneath the case to drain the loop. My question is will having a tube of around 15cm coming of the reservoir down to the drain port be a issue for flow as it the fluid will just flow down and then stop.

EDIT although I am using a T at the end, there will be nothing coming out the other side. This will just be a seperate line coming of the res just to allow me to drain.

no, no issues, the pump is drawing directly from the res, the extra tube will just fill with fluid and then be of no concern to the rest of the loop, though it will fill with stagnant water which could go off quicker than the fluid in the rest of your loop depending on what fluid you are running

thanks, gone with mayhems UV blue.

I may put a ball valve coming of the res maybe to prevent that.

No issue as said above, but try to fit the drain line to the lowest point of the loop, in the above image - there will be some fluid on the pump+top and tube connecting the res and pump. You will be able to get all of the fluid out by tilting the case but it would be far easier if the drain point is connected to the lowest point of the loop.

Thanks for pointing that out, how about if I connect it to the pump top?

Avathar77 · 25 Mar 2013 at 14:43

D5 pump will hold some fluid(small amount though) in the chamber. You will still have to tilt the case upside down to get all of it.
Show us a diagram of your planned loop layout, maybe there are better places.
What case are you using?

Case is a 650D. This layout will be changed a little (200mm rad in front) when I add in GPU in 6 months time.

How about this using a EK D5 top mounted this way:

When I add GPU and 200mm rad:

How many HDDs you have?
If you put them in the 5.25 bay, you may have more room to play with

I see your in bournemouth ash good to see another southerner

Tackle_Berry · 26 Mar 2013 at 10:59

Avathar77 - I have got 3 HDD's in the bottom cage, and then 2 SSD's in one of the 5.25 bays plus a fan contoller and a BD-RW.

Stuie - I know not many ocuk members down here, where abouts in Dorset are you?

stuie · 26 Mar 2013 at 11:11

Bournemouth or more specifically moordown

Tackle_Berry · 26 Mar 2013 at 11:14

Ah, I'm actually in Christchurch.

stuie · 26 Mar 2013 at 11:25

oh, you dont come across as being a pensioner

Tackle_Berry · 26 Mar 2013 at 11:31

lol, I was one of the old lady's that Top Gear dropped of at the bingo a few weeks back.

here ya go :

"T" piece with a tap and drain line

below the components level so you can drain away without too much hassle
it is NOT the ideal place for it, but it gets fluid away from the dangerous places so you can strip and clean etc. without killing CPU

stuie · 26 Mar 2013 at 16:19

looking at your planned layout you already have an ok spot at the bottom wont just decoupling the tube from the bottom rad serve as a draining option

andybird123 · 26 Mar 2013 at 16:20

good shout - even better for the OP as he can allow a little slack in the line from the GPU to the rad and he won't have the problem of a rad full of water like that pic has, just put a T line in between GPU and Rad and a bit of slack to clear the case when taking the stopper off

The other point worth considering is how the air will get into the loop. If the only access to atmosphere is through the drain line, the water tends to stay in the computer and dribble out slowly. I imagine the usual approach is to open a fill port on a reservoir, so air goes in there.

Water doesn't always follow the route you expect, so there's a chance that opening the reservoir fill port and the drain line will cause water to come out of both.

The XSPC reservoirs I favour have a M20 tapped fill port. Otherwise, you may be using a T line as a mini-reservoir. In either case, you can run a tube upwards from the loop to the top of the case, as a "fill" line. Plus the tube running downwards as a "drain". Then the loop is filled easily and safely by pouring water into the fill line. When you want the water out, open both fill and drain lines and it'll flow out freely.

Tackle_Berry · 26 Mar 2013 at 16:51

So what your saying is how it stands if I remove the stop cap to drain the loop from the bottom the water pressure may not let it drain, therefore I would need to remove the top cap from the reservoir? But doing so may allow water to push out the reservoir top?
