Black water holding tank

35 Allmand
Holding tank under the dinette (assume that in the normally place for it)
I have a small leak (confirmed by dye)
Not sure if it is the screw in "blank" on the stern side of tank or a small crack in the bottom.

Will be trying to remove the blank on the left and using Boatlife to seal it. I have attached a photo of the plug I am talking about.

Assuming that doesn't work, will be needing to R&R it.

Do we know who made the tank and if it still available?
I assume I will have to cut out the fiberglass under the dinette seat to do the R&R and than have it repaired.

If you have to have a custom tank made, who do you recommend?

I recommend plastic not metal after you remove it.

Many reputable fabricators online . Some have a huge variety of premades also. Now's the Time also to have the outlets exactly where you want them placed is where we bought ours.

I had my custom 77 gallon poly tank made by Triple M plastics in Maine. Awesome service. They delivered it to me.
