I am currently in the process of hard piping some of my plumbing, and I have been wanting a water jet in my AGP. So I have decided to do that, basically what I am going to do is come out of the heater with 1 1/2" PVC, and put a PVC union in, then to a long sweep 90, then down under ground to another LS90, over to the pool, roll up with a LS90 and a 45, level off to a combo tee, up to a valve so that I can drop a flex hose right off of the jet. Out of the back of the tee, I put in a 1 1/2 x 1/2 reducer to a 1/2 butterfly valve, from there to a female adapter to a quick connect tubing connector for 3/8 tubing. Seems like it should work, I am going to run the tubing around about a third of the way and then up next to a vertical support, and possibly drill a hole in the coping, although I think I will first just test it by running over it first.
Any thoughts? My hope is dual purpose, I want to use it architecturally with the light especially at night, and also I hope to get my Total Alkalinity down, which is still at around 180, after having messed with dropping it from around 270 last year to there. I honestly hoped it would go down over the winter, but alas it didn't, and I am sure that it is just God's way of teaching me to have patience even if it takes more than one season.
