We took our new coach out for its first camping trip this past weekend. It was a short trip, but we wanted to get to know everything. Aside from the refrigerator not working, and a pretty large leak in the roof, one of the things I noticed was that the grey tank flush bulkhead was leaking. Not terrible, but one of those things that will surely get worse. I decided to fix it now before becoming a bigger problem on a longer trip. It looks like a previous owner overloaded the male metal fitting with teflon tape and cracked the female bulkhead. Maybe it was an attempt to fix a small leak. In any case, I tried a couple things to repair it but made it worse.
Here is a picture.
My question is, how are these bulkheads replaced? Do they need to be accessed from the inside? I'm not familiar with this type of thing. I'm hoping other Alpine owners have the same tank and have tackled this in the past.
For reference, here is the healthy fitting on the black tank.
