nice looking conTRAPtion. i can see how having water flow with gravity (top to bottom) in a large area can make it harder for bubbles to escape.
IMHO, my vision of an ideal air-trap is sort of like this:
Code:
put filler cap here
tangential | |
inlet | |
------ |<----------this region needs to be widened
------ |
| |
| |
| |
| |<-----------the longer this region is, the better
| |
| | |_____|______
| |_______ ______centered outlet
|______________|
just a pipe dream for me, since my simple "T-coupler trap" has done OK so far.
