3/4 inch mip connection leak
Author: Frank1234 (IL) I piped a Kohler 728 bronze body transfer valve. None of the sweated fittings nor threaded leak except the 3/4 inch copper mip connection. I used thread sealant and tightened the @#$%& out of it. Is the problem the nibco big box store fitting? Any suggestions?

Author: PlumberLoren (CA) Probably. Take it back and see if it will thread into a fitting at the Big Box. They should exchange it for you.

Author: packy (MA) solder a short piece of copper into the adapter first. use GOOD teflon tape not the thin crap that if you hold it up to a light you can see thru it.

Re: 3/4 inch mip connection leak
Author: packy (MA) solder would work but needs to be very clean. flux the threads of the adapter before screwing it in. be sure to remove the guts of the valve before you apply heat.
