I am starting a new thread (for the continuation of http://www.troublefreepool.com/threa...961#post760961) since the topic queries has changed.
1. I need to figure out what the different parts of the pool are. See pics attached.
pic1 - what valve is this
pic2 - What is valve1 and valve2. When I switched off value2, the water to skimmer stopped. Does that also stop water from the main drain ?
2. I am trying to drain water from my pool to get CYA levels to normal (Its above 100 now). I looked at the option of renting/buying a sump pump but do not want to spend on it. I guess I can use the backwash option (by connecting the water exit to a hose)
I saw a youtube video where it is instructed to switch off water to skimmer and drain using the backwash option. I seem to have figured the valve for skimmer but want to be sure.
FWIW, there was a pump for the spa that does not exist now, so there may be some valves that are not required.
Thanks again for your help.
