Anyone know where I can find a replacement bulkhead like this one that is used for the drain on a closed loop? I have looked around, but can't find anything like this one. The dimensions are 6" long 2" wide threaded rear, 2 3/4" drain head. If this came apart at one time I think it is glued now. I would like a NFT threaded and not a slip as well. Don't know if you can tell from the pictures but I dremeled the glued PVC that was in this. I just don't trust it enough to use it at this point. If this failed about 125 gallons would spill out! Any help would be appreciated.
