Well, I think I may have screwed up.
I have a six zone/14 head pop up infloor cleaning system. After repairing broken T-valves considerable debris fell into the system.
It was clear that the debris was clogging the pop ups so (here's where I messed up), I took all the pop ups out at once instead of one at a time. Five of the 14 have small orifices and 9 large. Now I don't know which ones go where and don't have a pool builders diagram to help me figure this out.
Hoping someone has a solution to this issue.
