Hello all! I recently purchased a used Red Sea Reefer 450 and have started to uncover some plumbing issues. The drains and return have leaks and I'm having a hard time repairing them. The previous owner must have known about these leaks in the past as they used silicone around the O Rings making the pipes virtually impossible to get loose. Do you guys have any suggestions as to how to get the pipes loose so I can replace the O Rings? I'm not opposed to completely re plumbing the overflow if needed. I just want the thing to work.
I'll attach a picture of where the leak is to show you all the problem.
