Keep getting water in my mouth?

you mean while your hitting it or when you clear it?

 

Either don't pull as hard, or try putting ice in so the water doesn't go up as far

 

I just picked up one very similar to that and I'm finding that having more water actually makes it bubble less. I've been filling mine to ~2/3 - 3/4 height of the perc --- pull the slide when you fill so that the inside and outside of the perc are even when measuring. Lighter draw and a cube if all else fails...


BTW - love this design and price point for these bongs - picked up mine for $25! My first bong since college (~'90s)!


Edit: this looks like a pretty sweet setup! Slitted down stem - double joint - small ----- this will be on my short list when mine bites the dust!
