Summarizing the mistakes in the renovation of the bathroom

The bathroom is the wettest place in all rooms where moisture is most needed. The house is usually damp-proofed before it is sold. The damp-proofing of my house is a green layer of glue.
OK, now it's time to get to the point:
If we want to pursue a good leak-proof effect, we should do two more leak-proof measures. One time is done once after the hydropower is installed but no sand and gravel is filled, and the second time is after the sand and stone is filled. After that, you can do it again.
My mistakes:

One, did not test after completing the leak, the results of the rework test water.
The first leak prevention I did was to use pure cement and anti-leakage agent (not leak-proof glue) to prevent leakage, but after filling it up, I filled sand directly. After the results, the defendant needed to test the water and then fill it. It's easy to pour in sand and gravel, but it's difficult and tiring to be cautious, because you already have good water and electricity, and you should pay attention not to damage the water and electricity pipes when you dredge sand and stones.

2. When the water was tested, no stone was pressed against the clothed drainage pipe. As a result, the buoyancy of the water damaged the drainage pipe.
After digging up the sandstone and testing the water, the result was a problem at this step.
Because the water pipes and large drainage pipes have been installed, the water level is very high when the water is tested. As a result, the drainage pipes are subjected to a large upward buoyancy. As a result, the newly installed drain pipe and the existing drain pipe of the building are broken. Suddenly it dropped sharply and was completely drained. Troublesome, at the moment, only cracks are sealed with cement.
Because there are two bathrooms, one bathroom does not have this problem. However, it is still hoped that the “pretending friends” will pay attention when testing the water, and the solution is very simple. Pressing a stone on the drainage pipe is enough.

3. The squatting pan has uneven edges, resulting in irregular alignment of the tiles and the squatting pan.
Because some family members are not accustomed to using a toilet, a squatting toilet is also prepared. This squatting pan is sent when buying bathroom hardware on Taobao. However, the time of purchase does not pay attention to whether the edge of the toilet bowl is even, and the result is that the tile is in contact with the squatting pan. The edges are not neat. I hope you pay attention to this when you "pretend" to buy.

Fourth, Taobao shopping attention to the quality of handouts I have a lot of things this decoration is purchased from Taobao. Many “pretending to be friends” are still doubtful about buying things online. In fact, as long as you choose a good reputation in advance and with Taobao. The seller said "ugly words" in front of it, remembering to use "Taobao Wangwang" when negotiating with the seller. If the "negotiation" using the web version of the chat tool is unable to save the chat.
If you buy more things at a time, some Taobao sellers will send us something. This item must pay attention to quality issues. It is also money to send. This thing also needs the seller to give us warranty. The above "mistakes" The squatting device was said to have been delivered by the seller. At that time, I was unaware of the fact that I did not "negotiate" with the seller. As a result, there was a problem. The seller refused to retreat.

Compared with single-channel pipettes, multi-channel pipettes simplify all the tasks associated with microtiter plates that often occur in immunology, biochemistry, clinical diagnosis and food analysis. Multi-channel pipettes generally have 8 and 12 heads. The gun body can be rotated at 360°C, and each part can be disassembled and repaired separately. The lower half can be sterilized at 121°C.
