@@TanweerAhmed brother thoda NRS valve ke baare mai btao , aur isme post indicator ka kya function hota hai...i think it used in underground pipe line HDPE
NRS Valve is Non Rising Stem and it is used underground for fire hydrant pipeline. Post indicator is basically extension of NRS valve from underground to ground level. OSY Valve is Rising Stem and it is used open or visible pipelines

1:40 Its not skimmer drain. The pool you are explaining is Overflow type swimming pool as you can seen channel grating (overflow grating) all around the pool.
Separate permanent make-up pipeline is required for swimming pool because during filtration, water drain out and some water evaporates therefore pool water level down
@@TanweerAhmed and what abt lights in pool ... do we supply ac or dc ... in case ac supply there will be chance of current leakage ... for that do we use ELCB ..earth leakage circuit breaker
