Note the omission of the word “fellow”…. Does anyone know if this flange / bushing can be unscrewed or not? Is the plate threaded or is the the inset welded in? I know the elbow will come out.I do not want to break it if it is not supposed to come out. I am wanting to go from the existing size elbow to next size up that will fit when the bushing is removed.I am assuming the elbows are bronze. Is that correct?

Should be threaded into the plate, looks the same as mine, mine are all threaded holes.

Re: Marine sanitation enthusiasts, holding tank question
Ok, thanks, I will give it a try. Should have put some pb blaster on it before I left.

They are threaded but will most likely teak. Drill the holes out and re-tap. Easy job. Just be ready for the smell once you open it.

Re: Marine sanitation enthusiasts, holding tank question
Also about that plate... I'm getting head smell in the boat. An inspector found that the flange on top that everything connects to is leaking smell through a crack in whatever connects the plate to the tank. How is this plate attached and how is this issue fixed. All ideas are welcome!!!!

Re: Marine sanitation enthusiasts, holding tank question
The access plate is held on by screws, going into nutplates inside the tank. You can carefully remove each individually and re-tap without damaging the nutplates or breaking the tank to cover seal. I had to do so after the bonding system failed and the screws all wasted away.
