Answer first
Modern washers dump fast. Modern dryers pull hard. Legacy laundry rooms were not built for either.
01
Definition
What is this?
Laundry planning covers dryer receptacle type and breaker size, washer drain/standpipe height, supply valves, and GFCI where required for the space.
02
When to use
When does this apply?
Use before buying new machines or when the washer overflows the standpipe.
03
Failure modes
What goes wrong?
Adapter cords on dryer plugs. Shared 120V circuits for 240V loads. Ignoring flood-safe valves.

Questions homeowners ask
FAQ
What size breaker for an electric dryer?
Follow the nameplate — commonly a 30-amp 240V circuit with the correct receptacle.
Why does the sink back up when the washer drains?
Standpipe or shared drain limitations — cleaning alone may not fix capacity.
Are GFCI outlets required in laundry rooms?
Requirements evolved; we apply current code for the jurisdiction when remodeling.
