Question

Should a washer drain hose go up and right into the standpipe or should it go up the back of the washer have slack and droop back down and then go up to the standpipe?

Answer 1

For proper draining and to avoid potential issues, the washer drain hose should follow a specific configuration when connected to the standpipe:

1. Standpipe Connection: The washer drain hose should be inserted into the standpipe or the wall drain at a height where it will not come out or create a seal. The standpipe should be at least as tall as the top of the washer's drum or higher, typically around 18 to 30 inches above the floor level. This prevents water from flowing back into the washer and ensures proper drainage.

2. Loop or Air Gap: To prevent siphoning and water backing up into the washer, the drain hose should form a loop or an air gap before entering the standpipe. The loop should be above the water level in the standpipe and higher than the highest water level in the washer drum. This loop acts as a trap that prevents wastewater from flowing back into the machine.

3. Securing the Hose: It's essential to secure the drain hose to prevent it from falling out of the standpipe or creating leaks. You can use zip ties or brackets to keep the hose in place and prevent any accidental disconnection.

4. Avoiding Kinks and Drooping: The drain hose should not have any sharp kinks or low points where water can pool. Any drooping or sagging in the hose can lead to water retention, which might cause foul odors or mold growth. Keep the hose as straight and as smooth as possible to facilitate proper water flow.

5. Proper Length: Ensure that the drain hose is not excessively long or too short. A hose that is too long can create resistance and slow down drainage, while one that is too short might not reach the standpipe, causing water spills.

6. Regular Inspection and Cleaning: Periodically inspect the drain hose for damage or blockages and clean it to remove any debris or lint buildup that could obstruct the flow of water.

By following these guidelines, you can ensure the proper functioning of your washing machine's drainage system and minimize the risk of water-related issues. If you're unsure about the installation or have specific concerns, it's a good idea to consult the manufacturer's instructions or seek assistance from a professional plumber or appliance technician.
