Can this be done? (with diagram)

hello,
i was wondering if for my first w/c build,
could i, instead of haveing a "T" section at the bottom for dranage,
could i get a valve to put at the bottom of the T bit to stop any loss of
flow as it would cause resistance having that bit of pipe there?
hopefully this diagram will explain

thanks

You could pop something like this straight after the T joint, though I dont think its quite the solution you were looking for!

Have you considered using a Y fitting instead? Like so (excuse the awful paint skills haha)

Possibly smoother flow? I dont think the amount of disruption a T fitting causes is noticable anyway, I wouldnt worry about it!

i had seen those valves and think thats the way to go,
i also think im going to use a Y anyway as that will help also,
its also a lot easier for draining, without having it gushing out, just controls it abit

(lol i used photoshop and a graphics tablet so you did quite well

)

The most common thing I've seen is to have a t-piece somewhere near the bottom of the case and a fillport fitted into the base so you can put a tray under the case and drain it. This works very well for big cases eg. Mountain Mods UFO, Lian Li PC-343 where picking it up and carrying it to a sink isn't really an option.

well im looking to get a haf 932 so yes it would be quite hard to lift it to a sink

You say "instead of" but what you've drawn is basically the same as a T line without a valve, as far as water flow in concerned they will behave exactly the same whether there is a valve there or not. The advantage of a valve is you can remove the length of T to tidy the case up a bit, and put it back in when you want to drain. To sum up there is no difference between a T with a valve on the end, and a T with a length of tube and a fill port stopper on the end, water still has the shear at the T.

ok thanks a lot,
i think ill go with the T with a valve so i can screw in a extention pipe for dranage ect.

I'd put the valve on the other end though. The stationary column of water has little effect on the water flowing through the loop, but a valve does make draining it a lot easier.

After a moments thought, the valve makes a bit more sense at the end you've picked, as you can then have a usefully long drain tube that you take off when not in use. I'll change mine to this arrangement. Cheers.

p.s. if you've got a graphics card with a full cover block in the loop, you can take the drain line off a spare port underneath the graphics block, thus avoiding using a T junction.
