ual Washing Machines? Here's How to Effectively Use One Drain

Now, many households use two washing machines, but there is only one floor drain, which can lead to situations where one washing machine cannot drain properly. In this case, how can two washing machines share one floor drain?

How to drain two washing machines with one floor drain

You can modify one floor drain to create two drainage outlets. This can be done by using a T-joint to design one drainage outlet as two separate outlets, each serving one washing machine. The drainage center should be positioned at the location of the floor drain, which should be the lowest point of the tiled surface. The surrounding gaps need to be filled with prepared cement mortar. Generally, developers only leave one drainage outlet in the bathroom and balcony. If you want to use two washing machines simultaneously, you must convert one outlet into two.

What to do if the floor drain drains slowly

1. A slow-draining floor drain may indicate a blockage. If this occurs, immediate action should be taken. You can submerge the floor drain in water to use water pressure to open the plastic gasket and then clean it, making the cleaning process more manageable.

2. Inappropriate materials for the floor drain can also cause slow drainage. In this case, the only solution is to replace the floor drain. To ensure smoother drainage, install a direct-through closed floor drain, which not only drains more efficiently but also prevents backflow and helps with odor elimination.

3. Insufficient slope can lead to slow drainage. In such cases, you may need to increase the slope toward the floor drain. The slope of the drainage pipe should be more than 1%, particularly in smaller bathrooms where drainage pipes are more concentrated. If the slope is too low, water stagnation will occur.

4. Increase the slope in the area where the toilet or bathroom cabinet is located. If there is water accumulation in the bathroom, the water can drain toward the floor drain along this slope. If your bathroom has a squat toilet, design the shower area next to the toilet to resolve drainage issues.

In summary：this article provides guidance on how to manage drainage for two washing machines with one floor drain. I hope this information is helpful to those in need.
