I have a 2019 2800bh and over the past several trips, I've notcied water leaking from the under belly weep holes. I found it that the kitchen gray tank has a leak coming from where the gray tank connects to the drain valve. There seems to be some gray silicone type stuff that it's leaking from. Is this something I can just separate and recaulk? I'm not sure if this is supposed to be hard plumbed like home plumbing, but I assume it needs to be removable in case you have to replace the dump valve. I'm attaching a link to a video of the leak, along with a photo and hoping someone can give some advice. Thank you.
