When I drilled the bulkhead in my
sump I put it centered along the bottom of the
sump. But now I have decided to add a
refugium and to clear space under my stand, I need to move that bulkhead so it is aligned towards the right side of the
sump.
How should I block or plug the hole I drilled for the bulkhead once I remove it? I used
PVC glue to attach the
PVC to the bulkhead, which is then attached to a Union, so I could reuse the bulkhead, but I need something small than a bulkhead to block that hole.
Also, I bought some flexible
PVC (spa flex tubing) to replace
PVC on my return line. I am planning on attaching it to some slip Unions and attaching those to my existing union connections. Can I use
PVC glue on the spa flex tubing? I don't really feel comfortable with a slip fitting.
Thanks!
