Picture shows the plumbing out of my filter. ignore the two small 3/4" for aerators, not finished yet.
Pipe 1 i believe is the return.
Pipe 2 and 3 are for the bubbler and water sheer.
Given how the jandy valve is installed between pipe 2 and pipe 3, my understanding is:
a. i can turn off both pipe 2 and 3
b. i can turn on both pipe 2 and 3 (as shown in picture, current jandy valve position)
c. i can turn on pipe 2 and turn off pipe 3.
But given the current installation, can I have pipe 2 off and pipe 3 on ? It seems like it won't do this? But i think i would want that capability, for full independent control of bubbler and water sheer.
