I have a hairline crack in my holding tank that leaks into the lazarette and then into the bilge. Can anyone recommend a patch? Of what material is it made?
My humble opinion on this subject:
Ronco sells a new tank, don’t mess with trying to patch it, you have to take the whole thing out to try to patch it anyway. The model number is on the tank and they probably still make it.

Opinion is worth what you paid for it.

Hi T. 30 plus years ago we patched our tank with "goop" and prayer.. I thought it was a small chance that the crack would seal but it did and is still holding. I hope that I have not cursed the repair by mentioning it. Mid summer problem and I did not want to wait for a new tank and delay a cruise. Caution when you remove your existing tank. I learned the hardway that it is very hard to totally empty tank and when you lift the existing tank out it is easy to slop onto the cabin deck. Good idea to seal off the connections.

What do you mean by goop?
Well, I bit the bullet and replaced the tank after unsuccessful attempts to patch it. I did learn, however, what might have caused the crack in the first place. I was talking to a fellow sailor in a neighboring slip about the crack the cause of which has baffled me. I conjectured that perhaps the boat might have been exposed to a hard freeze, unlikely here in the PNW. He sited his background as a mechanical engineer and said that he thought it might be the result of a plugged holding tank vent line. He explained that flushing in the absence of venting would cause the tank to expand and pump out would cause it to contract and that this repeated flexing caused the crack. Sounds logical to me. What say you?
