Gunite tee body connection.

I am redoing my spa plumping. Previous installation the air pipes where so high up, they had to make 2" step around the spa to hide the air piping. Since I am remodeling, I am thinking of putting air pipes below water pipes.

Instructions says the air connections (spigot) should be facing up. I think this is for sucking air with venturi effect. But I do have an air blower. In that case, does it really matter if air pipe (spigot) is set downwards?

I am going to use similar tee body assembly as now, the one in picture below.

Good morning! This may be a good question for @AQUA~HOLICS. Let's see what he has to say next time he hops on the forum.

Sorry for the late response, I personally have never seen that exact type of fitting used in any of my spa applications. I would think that the orientation of the Venturi fitting should be positioned upwards so to keep water out and only allow air in but then again I’m not familiar with that particular product.

Thanks a lot for your responses! I did some experiment, with forced air (Blower) it does not matter if the venturi is faced up or down.
