The property management of the community does not allow the balcony floor drain to discharge laundry water. Why?

Residential property management also prohibits balcony floor drains from discharging laundry water for various reasons. The details are as follows:

1. Considering the pipe diameter, rainwater pipes are generally standard It is made of pipes with a diameter of more than 2 inches, that is, more than 50mm. Washing machine drain pipes are generally made of pipes with a diameter of 1 inch, that is, 25mm. Therefore, from the flow of water, the rainwater pipe is enough to withstand the drainage of the washing machine, and there is plenty.

2. Nowadays, the rainwater pipes on the balcony are usually drained directly into the drainage ditch on the first floor. There are drainage ditches that are drained to the rainwater wells, but the water from the washing machine is sewage and contains chemical components. During the drainage process It will cause soil pollution on the ground, may also cause the building to be corroded and the pipes to age, which will be very troublesome for future maintenance.

3. Nowadays, regulations in many places require rainwater and sewage to be diverted, and gray water treatment (reclaimed water treatment is required by individual cities). Rainwater collected on the roof and ground can be reused. It can mainly be used for greening irrigation. If there is a washing machine, The mixing of sewage will cause the chemical composition of the water to exceed the standard.

4. The drainage of kitchens and bathrooms is sewage discharge. When designing, the discharge of washing machine water is directly set according to the sewage discharge. These sewage are treated by sewage treatment plants and purified to meet the standards. It flows out of the natural river.

In current residential designs, some developers have taken into account the location of washing machines and installed sewage pipes on balconies and bathrooms, but only a few high-end residential areas have them. If the conditions at home do not meet the requirements, you can check to see if it is close to the kitchen and bathroom, and you can lead a pipe there. If not, then just leave it to the bathroom.
