Best place to put drain tap on pump/res?

Reality|Bites · 25 Sep 2018 at 14:11

Just a quick question, Is it better to put the drain tap on the inlet or outlet of the pump/res combo?

Depends were your pump is located.

Always best to have the drain port at the lowest position in a loop to let mavity help drain it.

If it has to go direct on a pump i would choose outlet

it's going on an alphacool eisbecher 250ml.....still to swap it out as the EK 140 hasn't leaked again yet....It only gives me grief the first few days of a new fill as I tilting the case. The res doesn't screw it properly and easily pops out with pressure from air or just the weight of the water. I'm not alone I read a similar thread on reddit about it.

I was going for the ek d5 140 res and got a t-piece for the out let of the pump with a 90 degree and drain valve with a end cap on it.

I don't even bother with a drain plug, if for any reason I need to drain my loop (which is pretty much only if I buy a new part for it or a new case), all I do is get a jug, remove the CPU block off the CPU, carefully remove one of the tubes off it, and tip the initial fluid out of the block and tube into the jug, then put a clean piece of tube onto the barb on the cpu block, the other end that I removed into the jug and gently blow through the clean tube, 20 seconds later my loop is empty.

It's always so much easer with a drain valve,I fit one in every loop I do.

Must be nice having all that flexible tubing and movable blocks

Oh yes

, I don't have the funds or the patience to go hardline, and as im always changing parts, especially motherboard lately, it makes it so much easier.

Would it still work on the inflow port as it makes loop easier in new build I’m doing?

Yes it will work on the inlet port as that's where I have my drain valve connected to my xspc photon d5

Do you have to turn the pc upside down to drain?

No the pump has one outlet and 2 inlets, all located at the bottom of the res which is mounted low in the case. Once I've drained most out I take off a tube from one of the radiators and connect a clean tube which I blow through to get any remaining liquid out.

Exact same process with mine. I have a multi-port top and have a valve on the standard return inlet back to res.

Drain what’s in the reservoir and top of the loop. Then blank the outlet on the res and blow through the bottom radiator which pushes everything through the loop back to the reservoir and out the valve.
