Choosing Washer Location
Choosing a suitable location for the washing machine is crucial. The floor should be flat and firm, capable of supporting at least 400 pounds (approximately 180 kg). Hard surfaces such as tile or concrete are best, as they are less prone to damage from vibration. If the washing machine is located upstairs, use a washing machine tray with a drain outlet to prevent leaks. Ensure there is sufficient space next to the washing machine for a dryer, and that connections do not obstruct the dryer’s vent.
Other things to check:
- A shut-off valve should be provided near the hot and cold water lines.
- A good drainage system, such as a 2-inch (approximately 5 cm) riser or a floor drain with a P-trap.
- A GFCI-protected electrical outlet should be available within 3 feet (approximately 90 cm) of the washing machine.
Checking Water & Drain Lines
The washing machine requires suitable water supply and drain lines. The water supply line should be close to the washing machine. A shut-off valve helps ensure safety. The drain hose should be at least 2 inches (5 cm) in diameter. This size is more suitable to prevent blockages. Some older houses have narrower drain pipes, but wider ones are better. Riser pipes or floor drains should be connected to a P-trap. This prevents odors from entering the house.
Planning Electrical Access
The laundry room needs a safe electrical outlet. Regulations require at least one outlet in the laundry area. Washing machines and dryers must be grounded for safety. All outlets in the laundry room need GFCI protection.
“All 125V, 15a and 20a outlets in laundry rooms need GFCI protection.”
