Holding tank leak

[kellerbees]

Have a leak in my galley holding tank. I've accessed the tank and would like suggestions as to a good product to use for repair.

Where is the leak? On a seam, or a fitting?

Its below the outlet fitting on a seam.

Is it where the outlet pipe sticks into the tank and is held in place by a hose clamp? If so maybe try tightening the clamp. Can you post a pic with an arrow pointing to exactly where the leak is?

If the actual leak is accessible, I had excellent results repairing a crack in our grey tank several years ago using a repair kit from Plasti-Mend. http://plasti-mend.com/cart/index.php?route=product/product&path=59&product_id=96

Ours developed a leak at exactly the same place. Plasti-Mend stopped the leak for a while but then leak re-appeared. I even drilled holes on both ends of the crack to keep it from growing. Ended up replacing tank, no more issues.
