Ro water reservoir question /silicone help

Bapeluso · Apr 3, 2020

Hello all, so I transformed a 55 gallon plastic drum into a reservoir when I had first started up my tank about 2 years ago. I had made the design flaw of drilling the hole for my bulkhead on the side of the drum where it is curved. I hadn't had any issues with it leaking until recently. I decided it would be worth a shot tightening the bulkhead a little and that didnt work. Then I decided to put silicone around the bulkhead to create a better seal. When I did this, I didnt realize I had gotten the wrong silicone which in the fine print said "mold free". Now I'm trying to remove the bad silicone and put on the right stuff. My problem is, I cant get the bulkhead loosened up now. It doesnt matter to me how clean it looks, but was wondering if I were to remove as much of the wrong silicone as I can and reapply the right silicone, if it would hold and would it be ok to use

Remove the bulkhead completely and buy a uniseal. They are basically bulkheads designed for curved surfaces.

I would get as much of the silicone off as you can.

Try using large channel lock pliers. Even if I had to take a dremel and cut the old bulkhead off I would. And like Homer said, replace with a uniseal.

I was just going to post that I would cut the bulkhead off.
