Well, life once again got in the way, i really need to know what bit i will need to drill for a return with 1 1/2 '' drain lines, when i went to lowes i bought the wrong valves and bought 2'' true unions, stress is getting the better of me and im really not wanting to start drilling through a brand new tank so i need to make sure i do it right the first time.
I really wanted to be able to say i did it myself, but its starting to look like that's not going to be the case and it seems im losing faith faster then i can come back up.
