We have 3 bubblers in our tanning ledge. I had always wondered why I had two return lines from my equipment pad. Then like a light bulb it hit me!!! One line goes to just the bubblers, the other line goes to the other wall returns. So with great enthusiasm like a kid in a candy shop I hopped right on over to my equipment pad and turned off the wall returns and fired up my new 2.2 sfhp motor that I upgraded to last weekend (it used to be a 1.65 sfhp motor). I was hoping for Yellow Stone guisers! My neighbor has a pool that was built by the same company and his bubblers shoot up a good 4 feet. Well, sadly, while my bubblers did shoot up a bit more, they were only about 3/4 to 1 foot above the water.
So how can I increase the pressure? Right now it's non-threaded 1.5" PVC
Do they make friction expanding eyeballs? Or do they make a tool that can add interior threads to my existing PVC? Also, how bad will raising the pressure be on my equipment/motor? I'm pretty sure once we have a whole gaggle of kids over they'll soon realize if they put their foot on one bubbler, the other two will shoot up even farther. I can just see the antics when they decide to get 3 kids involved to block all 3 returns at once.
