DIY Goof of the Day: That Sinking Feeling. I finished connecting the faucet and drain assemblies for a new bathroom pedestal sink for my in-laws. I went to the basement to reroute a few pipes before securing it to the wall. I cut out old copper piping with a reciprocating saw and reconnected the lines. I returned to the bathroom and found that the saw's vibrations had toppled the sink and pedestal, shattering both!
