Firstly this is my first post to what seems to be a fantastic site. I uploading a photo of my equipment and hope have someone explain to me what each of the valves do and exactly what controls what in the spool/spa, if it would be possible from the picture I have uploaded (I numbered each valve 1-5).
When we bought the house, I had the pool inspected and the Pool inspector guy went through everything with me at the time, but my brain was too busy being excited that I was about to own a house with a pool so it really didnt sink in (and boy how i now regret not listening intently to every single thing he was saying!)
If anybody could help me understand or give a basic idea what each thing does I would appreicate it more than you could imagine, nothing worse than having all that equipment in front of you not knowing exactly what would happen if I decided to turn one (which I am too scared to do). some are quite obvious where they go to and the automatic ones seem to control the spa and the other the drain...I think. Thank you in advance for your time.
Hopefully the picture is clear enough to identify where everything goes.
EDIT: Added additional photo (note the filter is wet as I opened it earlier to check the catridges and that weird green color is because I reduced the quality of the photo so much to make it so I can upload it)
