Air-trap - draining
 

I building the air-trap to Turbokeu, since the two T's is not very good to fil or make the system air-free.
But they are very good if you drain the system, you blow air at the first and the water comes out the secend T.

How can I make the draining part easy with the air-trap?

Hmmm, no reply.......

Do you think a single valve on the bottom of the case would be enough?

Put a 2 valves on a T directly after the pump, and switch it on.
(requires closed loop, og very airtight res.)

Yes, one valve in the lowest part is enough to drain the system (do not forget to unscrew the lid of the airtrap for air intake).

For easy filling & bleeding you need the second valve.

Doesen't you just put water in the air-trap to fil it and then the air-trap does the draining part?

Only if the outlet of each preceding component is at the highest point of that component as you bleed through (otherwise you need a valve at the highest point of that component).

That's how I see it anyway. Think of underground caves full of water but for an air pocket at the top.
Or better still, an upturned funnel pushed into a sink full of water - it will hold air as long as you keep a thumb on the top but will fill with water as soon as you release the thumb.

This could apply to vertical mount rads for instance - with the barbs at the bottom, it's easy to trap air at the top, even with an airtrap, unless you can bleed it in an orientation where the barbs are at the highest point, then reorient it to suit.

For filling of the system see next picture...
Close lid of airtrap firmly, close big valve, open 2 little valves, suck on tube on upper valve until pump is filled with liquid, start pump, let circulate a few minutes, open big valve, close 2 little valves, and circuit is filled and almost bleeded...(+ disconnect 2 filling tubes)

To drain: Stop pump, open airtrap, open lowest valve and let liquid drain in a recipient (to empty system)...
Easy...

I use the the airtrap only to fill with cooling liquid when level goes too low...
