leaking MLT

[allied35]

just finished my mlt its a 48 quart cooler with a copper manifold. it is leaking a little around the fittings... i was looking at some different websites about this problem and a saw a few had used silicon on the inside to seal it. is that a good idea?? doesn't seen food safe to me. if it's not good then i'll have to do the pvc thing inside the walls for more strength. thanks

Not knowing how it's mounted I'll throw out the idea of using plumbers putty. Mine was weeping so I put some putty in between the washers. It's for potable water and can always be removed if need be.

never thought of that. that seems like a much better idea then silicone

do you have a half inch ball valve on it?
you need one of these Half inch gaskets

Or make a poor man's gasket out of a silicone baking dish... I found one at some outlet store for a few bucks... Hell I just made a gasket for a sanke / tri-clamp fitting...

I like this design. I have had very little problems with leaking.
