3. Find the slope and leave the groove: find the slope on the ground, find out the slope of 1% 2% to the floor drain at the leveling layer, the drainage slope of 50mm outward on the floor drain edge is 3% 5%, and leave 20mm 20mm groove around the upper mouth of the floor drain.

4. Fill the groove coating film: the groove around the upper mouth of the floor drain is tightly embedded with sealing material, and then the waterproof additional layer of the coating film is paved with carcass reinforcement material, and the depth of the additional layer coating film into the mouth of the floor drain cup should not be less than 50mm, and then the waterproof coating is painted according to the design requirements;

5. Water storage test: do a good job in water storage test, and observe that there is no leakage as qualified;

First of all, it is a procurement process, not blindly going to the market, which is easy to buy wrong, and it will be troublesome to exchange for it. We should understand the caliber of the drain sewer pipe in advance, the current general 50 PVC pipe, if it is cast iron, it should be larger, the diameter of the purchased floor drain should match the diameter of the PVC pipe, the reserved hole for drainage is larger when handing over, and some will be trimmed during decoration, so it is necessary to do the drainage outlet according to the size of the floor drain, it is not recommended to trim the drain first, and then go to buy the floor drain.

2. The location of the floor drain installation.

Usually it will come with a small section of pipe, put it in the sewer pipe, and then aim the drain core at the drain and apply a layer of cement to basically no problem. If the floor drain will shake back and forth, or there are gaps, then it is easy to leak, so special attention should be paid to the bonding and sealing of the connection between the floor drain and the sewer pipe, which can be sealed with professional adhesives or glass glue.
