Ground leakage is an important interface between drainage system and indoor floor. As an important component of drainage system in residential buildings, its performance directly affects the quality of indoor air, and is very important for odor control between bathrooms.
Firstly, the reserved drainage holes should be repaired so that they are completely consistent with the purchased floor drain, because the reserved drainage holes are relatively large when real estate dealers hand in their houses. Among them, the aperture of the floor drain grate should be controlled between 6 and 8 mm, which can prevent the entry of hair, sludge, sand and other dirt.
Secondly, it should be grasped that the multi-channel ground leakage inlet should be installed according to the actual situation. Multichannel floor drain is a floor drain with multi-functional joints, which can undertake facial washers, bathtubs, washing machines and floor drainage. This structure can solve the problem that a sewer outlet needs multiple drainage.
There are two ways to add floor drain where there is no floor drain. One is to raise the ground and distribute sewer pipes; the other is to break through the floor and redistribute sewer pipes.
Texture of material
There are mainly cast iron, PVC, zinc alloy, ceramics, cast aluminium, stainless steel, brass, copper alloy and other materials.
1.Engineering plastics: Engineering is widely used, cheap and inexpensive.
2.Cast iron: cheap, easy to rust, beautiful, sticky dirt after rusting, not easy to clean;
3.PVC: Low price, easy to be deformed by temperature, poor scratch resistance and impact resistance, beautiful;
4.Zinc alloy: cheap, easy to corrode;
5.Ceramics: cheap, corrosion-resistant, impact-resistant;
6.Cast aluminium: middle price, light weight, rough;
7.Stainless steel: moderate price, beautiful and durable;
8.Copper alloy: moderate price, practical type.
9.Brass: Heavy, high-grade, high price, surface can be electroplated.
