I specified that all drains and skimmers should have valves at the pad. My PB did not follow this when they did it. They put a 3 way between the two skimmers and then T'ed into the drain line directly (no valve on drain line) then to the pump. So, it appears that I have no way of turning off the skimmers (if I ever want to drain the pool) and I have no way to airlock the drain line after blowing it out.
So, did they just make my winterizing much more difficult? Do I now need to go under water in the deep end, remove the drain covers and plug each line after blowing out?
Are valves usually installed on each drain and skimmer line or is my request overkill and it is fine the way it is?
