New pool owner here. Working on slamming it now, but that's another thread. In the mean time I am trying to get the basics of my system down. I had to replace the motor on the pump and that is up an humming along now. (Mind you the pool company quoted me over $800 for a new pump since they said they couldn't get a motor for this old pump. Somehow I managed to find one on ebay within 5 minutes for $150 and it even turned out to be local so I just drive up and got it immediately)
My system has 3 shutoff valves that you can see in the pic. The one on the far right seems to be for the main return jets to the pool. Just left of that turns on some seat jets, I have been keeping those off for now as I'm not sure they do anything but make bubbles for the seats. The one I cant figure out is the farthest to the left. When I open that one I immediately lose prime on my pump so it must suck air from somehwere? Is it maybe connected to the pipe in the middle sticking up in a T shape?
I have a cartridge filter lurking in the background and am a little disappointed I cant vacuum to waste. I am thinking about plumbing a diverter valve in between the pump and the filter to give myself that option. Any thoughts on if this is a good or bad idea? Thanks!
