Re: Adding a Return.......
Okay I did some searching...
If you put some red dye in a syringe, and release it within a 1/4 inch of the bottom drain, if the drain is open the dye should flow into the bottom drain. The water needs to be relatively calm so watch your movements. This means you'll have to get in to do this, not sure if your water temps are condusive to this.
If there is a better way to test it I'm sure someone will offer it.
In the skimmer with the 2 holes, I think the one you don't attach the vacume to that might be where the bottom drain goes to....
