When the trap is too deep, liquid may flow through it too fast, which can lead to siphoning of the trap seal and sludge buildup. If installing a sink with a deeper bowl results in a trap seal deeper than 4 inches, you’ll have to open up the wall and relocate the trap arm connection at the drain (see photo, above).
