01
Why the pipe objects
Caulk cures into a flexible waterproof solid that can adhere to pipe walls or obstruct a trap.
02
Do this instead
Let small leftovers cure on scrap material and follow the label and local waste instructions.
03
Already did it?
Do not add solvent or chemical drain cleaner. Remove uncured material from the fixture without pushing it deeper, then contact a plumber or hazardous-waste program.
