freshwater tank leaking under v berth
 
The boat is an islander 30 with a 25 gallon glassed in fresh water tank under the v berth. If the tank is full or we are heeled over the water leaks from the 6 " inspection port on top of the tank. The inspection port is a regular deck plate type with a flange, screwed to the top and bedded with marine sealant. Is there a better way to seal the opening in the top of this tank than a deck plate ? What kind of sealant would be better than regular silicone ? Should I use 3m 4500 ? Since I sleep in the V berth it is awful to get into bed and find the cushions soaked from below. And no I do not have bladder trouble.


Thanks,

Mine uses a rubber gasket with mechanical lock fastening. That would be my first choice as you will want to access it periodically.

If its the screw in type deck plate clean the treads and apply plumbers putty. If not there reasonably inexpensive to replace.

I would NOT use 5200 as you would never be able to remove it. Plumbers putty is a good choice or if you need to remove the housing, rebed with silicone, particularly if it is a poly tank as silicone is a good choice for those tanks and is flexible to handle expansion and contraction.

5200 also cures using an isocyanate compound and isn't approved for use on POTABLE water tanks.
