venturi
 

lets see all the venturi's you have made yourself

anyone?

i am about to make one myslef and pictures of some that people have already have made would help alot, thanks

I had a diagram of the one I built, but it is very simple.

3/4" to 1/2" bushing attached to a 1/2" to 3/4" bushing. I use a MPT to FPT, but you can use a glued fitting. Drill a 1/4" hole in the middle, attach a 1/4" tube -- make sure it's higher than the water level, and you've got your venturi. No muss/no fuss!
