Potential Plumbing Problem / Water Disaster

[corey.nolta]

When I upgraded to my 90, I purchased it off another member who was tearing down. It was a tank he drilled himself. He had drilled a hole in the bottom left corner, about three inches from the bottom, to utilize for water changes (I'm assuming). However, I personally do 95% everything directly from my sump, so I have never used it.
Well I was behind my tank tiding up and tucking away some stray cords and I bumped the pipe. And now I have a pretty consistent drip. It's not an emergency, yet. But it's enough to cause concern.
The drip is located on the threading where the PVC connects to the bulkhead. And everything is as tight as it can be. With it being at the bottom of my tank, I can't really do much without draining 95% of my water, which I really, really do not want to do. But I don't want to keep messing with it in case I make it worse. There is a valve, but with where it is located, it's pretty much useless in helping. What are my options? Any advice on how I can MacGyver this thing? What's the best course of action?
Thanks!
(Worst case scenario, I turn my entry way into a swimming pool. It's a scorcher here, so I guess I'd have a way to keep cool???)

If I am seeing that right, is that PVC fitting screwed on the outside threads on the bulkhead?
If so it needs to be drained and changed. The exterior threads on a bulkhead are not tapered pipe threads and will not seal correctly. You may get a fitting to start on it but it does not tighten up correctly since the bulkhead threads are straight thread like a nut and bolt, they are only there to tighten the nut against the glass .

Insert you a short capped piece of pipe in the bulkhead from the inside it will keep any water from coming out then you can take the plumbing off from the outside and figure out why it's leaking

That looks to be correct. I do not have containers to hold that kind of volume of water in order to drain the tank completely. I do not have a need to actually utilize the drain set up, so is it something I could just silicone around the fitting and threads? It wouldn't be pretty, but it's behind the tank. Or would that just be a temporary band aid?
I'd like to try and find a way to solve the problem without draining the tank. I will if I have to, but I'd like to save that for a last resort.

Pm me your number I'll explain better what I mean

@Greg B I understand what you mean. My last reply was being typed prior to reading your suggestion. I'm looking to see if I happen to have the size I need laying around. Great suggestion!

Maybe too tight? I had one leak when I tightened it down too hard.

It looks like the white PVC threaded reducer is cross threaded
