Antifreeze draining out

[sevenoakspool]

Hi, I have a problem with filling my pipes with antifreeze. The returns into the pool are plugged so I am assuming the antifreeze is draining out of the main drain. This is my set up. Are the valves positioned wrong? I am filling the pipe on the left with 3 at bottom.

Where is it leaking from? I'm assuming you mean when you pour it in that union? If the returns are plugged the antifreeze is having a tough time going in a closed pipe. Simple really, if the returns are above the water, open one up, that will make the pouring easier. Did you blow out all the lines and skimmer and main drain?
