FYI -
The 1/4" tap is called 1/4" NPT (National Pipe Thread), or 1/4 - 18 (18 threads per inch).
I wander how we can make a ventury for the CO2. Supposedly this would break up the CO2 into smaller bubbles before it hits the pump.
Maybe we could use 1" PVC to just before the pump inlet, bushing it down to 1/2" & use a 1/2 x 2" nipple w/ a short piece of tubing inside the nipple. Tap the nipple & go through the tubing, & connect nipple to pump w/ a 1/2" threaded coupling. The other side could remain flex tubing for movement option.
Do y'all think this would work?
