How to seal inspection ports on water tanks and leak repair
Have old "food grade" polyethylene fresh water tanks on our 1966 Alberg
Odyssey 30. One does not have an inspection plate. I cut a hole and installed one using a neoprene ring (cut from a mouse pad) for a gasket but don't feel confident that it will be a 100% seal. Was wondering if plain old silicone would be OK to use? Will it contaminate the water? Any other suggestions? Cork gasket with rubber cement? Also --- I repaired a few small leaks by heating the tank area with a heat gun, then using a hot glue gun to "weld" over the crack. This seems to have worked for the time being, but, once again, I'm after the "mil spec" method of repairing this material. Anyone know? Thanks for any suggestions.

The leaking cracks are near lower edges so an inspection plate wouldn't
be an option. Is silicone safe for drinking water? |

Does any vendor have a satisfactory inspection-port kit for a built-in
water tank in a fiberglass boat ? If not, how is one properly fabricated/installed ? Also, how should said built-in tanks be repaired in the event of cracks, fractures, etc. ? Thank you.
