As the title states I need to do a partial drain and I have googling the issues with hydrostatic pressure and I have been hesitant to do so thus far. Just FYI, I am very new to pool ownership. I have been in the house for one month and my pool is turning into the green monster.
I have the TF-100 kit and ever since I moved in, my CYA levels have consistently been in the 90s -100s if not more. I have tried to go higher ends of FC levels, however it's not successful.
Attached are the pics of my setup, I just need to know step by step what I need to do.
So, The first picture is my main drain and the two skimmer returns...Currently the "off" is pointing towards the plant and valve handle is in line with the skimmer returns. When draining which should the handle point.
The second picture shows my drain pipe --- it's underground and ends at the tree line at the end of the yard.
Please give step by step directions as I am a novice...Also, with my multiport valve, do I point to waste or Backwash.
Thanks in advance. Looking forward to doing my first SLAM
