I want to replace some multi turn inlet shutoff valves with 1/4 turn ball valves in a relatively tight space under my kitchen sink. The distance between the valve and a second sweated T connection is 1.5-2 in.
1) How best do I keep cool the T connection while I remove original valve and replace it with a half in male thread?
2) what's a cheap but effective insulator I can use to prevent overheating the adjacent wood and pvc structures?
Thanks,
David - Dallas

the tee joint should not be effected by low heat applied slowly to remove fitting.
YES! don't start the cabinet on fire by carefully applying directional heat away from flammable surfaces. I often use a piece of sheet metal as a heat barrier.

Because of the way the valve is constructed, and depending on how the piping is arranged it the wall, you MAY NOT be able to drain all the water out of the valve and if so, you won't be able to unsweat no matter how much heat you use.

loosen the packing nut to remove the stem and handle. you will have less mass to heat. depending on the orientation of the valve and the type flame you use, you can aim the flame into the inside of the valve to help keep the heat localized.

Sheet metal can help deflect a direct flame, but there is still significant heat behind the metal, and the flame will sometimes follow the metal to the edge and catch something there. I would use a spray bottle with water and wet the cabinets first, use sheet metal, and keep the bottle there just in case something starts steaming heavily or smoldering.

You can use a heat shield gel that will stop the heat where you apply it. It's good stuff.

Thanks guys,
I appreciate the advice. I will cut some sheet met. al and use the spray bottle and probably wrap a wet cloth, too. All the while cussing out these damn cheap cutoffs.
