Nope, no auto fill that I'm aware of. It is a maybe 30-yr old pool, and the guys only did the bare minimum to retore it back to function, mainly replaster and tile/coping repair.
It is not fully stopped but now water rises very slowly. Not sure if it is because I plugged the polaris ports or because there is indeed this much water in the pipes. It took over 3 hours to reach this point.
Now that it is open, and considering this much hassle of water needs to drain out, what apparatus I can use to not having to go through this next time pvc repair is needed?
I do still have that plastic ball valve, but not sure if it is that unreliable (I heard return line isolation valve is not absolutely needed, but in my case...).
