Wow....i just use a rubber hose and a bucket....
Stick the hose in the DWC container, suck on it to start syphon action then stick other end in the bucket...just like stealing gas...
Your DWC has to be higher up then the bucket if you want to get it all...
I just crack the lid and slide the hose in...I think it's 3/4 size...
