What is the proper way to cap off a drain pipe behind a dishwasher that you no longer use?

Answer

if it's plastic pipe you can just buy a glue cap and glue it on. If it's galvanized or cast iron pipe you can use a gym cap, (arubber cap that comes with a hose clamp). Just put that on the pipe and tighten it down firmly. this will prevent any sewer gas from coming out of the drain.
