Hello all!!! I can't wait to show y'all some before and after of my pool remodel but goodness, it is taking forever to complete.
1) I think my pool may have been serviced by idiots, who knows, but I know the part in yellow is unnecessary. How can I best fix that ? just cap it at the blue line and make the rightmost valve a 2 way? Is there a better way? Am I correct in understanding that if I ever set the left valve to off (which I *think* controls the pool jet returns), I cannot run the Polaris? If I would want them off to heat the spa, why wouldn't that be controlled by the actuator? Or is it?
2) The spa plumbing on the left I do not understand. I do not understand the two horizontal pipes and why they are needed. I understand that the purple actuator moves when the controls are put into spa mode. In pool mode (shown) the water flows down the right vertical pipe? and in spa mode it flows down the left? The red check valve is preventing water flowing which way (red)? what exactly is the green valve doing? I assume it's only doing something in pool or spa mode but I'll be darned if I know which. Does this look right?
3) getting a new heater and I am going to put in a bypass before it's installed if I can. I'm taking out the tablet dispenser because I don't use it, and it just gets in my way and is one more place for leaks. (we have hard water and my understanding is that tablets will raise my CH which I do not need). I already have the check valve for the bypass in place and just need to add the 3 way valve in the correct place. My question is how do you set it all to be certain you have the correct small amount of water running through the heater? We do not use the heater much so it'd be bypassed from about March to October, maybe even more.
I hope these are not really dumb questions. Y'all have taught me a ton and I appreciate it so much.
Thank you thank you thank you,
Marci
