First, the wall surface
1. Check the wall for cracks.
2. Check whether there is empty drum on the wall. If you hit the wall with a small wooden hammer or something, the sound you make when you knock on the empty drum is not true. It is easy to hear it. Make a mark and fill it with putty during the renovation.
3, check the wall putty, whether it is waterproof putty, you can bring bottle of mineral water, splash water on the wall, hand to touch, to see if there is mud, if not proof of the wall of waterproof putty qualified.
Second, the roof
1. Check the roof for cracks.
2. Check whether the yin and yang corners of the roof and the wall are horizontal lines. If not, use a stucco plaster to lower the water level and then use a waterproof putty to level it.
Third, the ground
1, check the formation of the ground
2. Check for cracks and backsuds: Whether sand appears on the ground when the floor is used for ankles. This problem occurs when mortar ratio or cement quality is unqualified and the mixing is uneven.
After the big face is checked, the details are checked. The construction unit of each house is different, and the quality and design are also different. The professionalism of supervision plays a very obvious role in these aspects. The details are very important. Many places are invisible to us, or there may be problems with the decoration of furniture in the later period.
Fourth, doors and windows
1, check the strength of doors and windows
2. The function of the inspection window a. The sliding of the door and window is smooth, smooth and smooth without serious scratches, and the profile is not cracked or broken.
b. hardware accessories: complete, correct position, solid c. seal quality: when the door and window are closed, the fan and frame, fan and fan no obvious gap, the seal is not loose, does not fall off, not exposed.
d. Door and window frame, fan vertical, not bent e. Glass pollution, no damage, double glass sandwich without dust and moisture, evenly divided.
f. Whether the window drain hole has been opened. Unopened water will flow into the profile.
Fifth, the circuit
1. Check whether the sockets and switches are set properly. Whether the circuit needs to be remodeled in the decoration. First, look at the individual needs. Second, see if the socket and switch settings in the house are reasonable and convenient to use.
2, check each light switch and power outlet can be used normally, with a mobile phone charger, or electric pen plug to check whether the power outlet power, of course, professionals will use a dedicated socket check.
Six, waterway waterway is mainly reflected in the kitchen, bathroom. The general situation in the bathroom is 2 floor Drains, a toilet water pipe, a bathtub water pipe, a sink basin, see if the setting is reasonable, and then according to the needs of their own decoration to decide whether to change, but the specific transformation program To listen to experts' opinions.
The most problematic problem is that many people want to change the toilet's sewers and have gained more space. However, rebuilding the toilet water pipes needs to be reconstructed at the sewer pipe road at the top of the downstairs, which can easily cause a lot of trouble. It is difficult for the owners in the downstairs to agree to make such changes. Therefore, it is not advisable to change them by yourself (using the method of raising the ground is prone to poor drainage). Listen to the opinions of professionals.
Seventh, the gas pipeline gas meter is a small thing that occupies space. How to adjust the position of this meter also needs to listen to the opinions of professionals. It must be transformed by the gas company. It is very important.
Eight, waterproof waterproof said here, refers to the kitchen and toilet waterproof. Of course, some of the houses that are currently delivered have already declared that they have not done waterproofing. This requires renovation. If waterproofing is already done at the time of delivery, we have to verify whether the waterproofing is done well. If you don't try it before the renovation, then if you find something leaking when you finish it, then the maintenance project will be big. You have to remove the floor that has been renovated to make a new waterproof layer.
Acceptance of the waterproof method is: use a cement mortar to make a gong to block the toilet door, and then take a plastic bag covering the sewage / outlet, and then tied, and then put the water in the toilet, shallow on the line (greater than 2cm) . Then, about 24 hours after the property and owner downstairs, check if there is any leakage in the ceiling of their home toilet.
Nine, inspection pipeline The pipe referred to here refers to the drainage/pollution pipeline. Utah is a sewage outlet such as a balcony. When it is accepted, take a water-filled appliance in advance and pour water into the outlet. See if the water is flowing smoothly. Why do you want to accept this? Because during construction, some workers often “stolen†this work when cleaning. Put some cement residue into the drain and run away. If the cement is more viscous, it will clog at the elbow and cause drainage difficulties. There is another situation, but it is not related to acceptance. That is to look at whether the sewage pipe has water storage deodorant elbow. According to experience, if the sewage pipe does not contain water and deodorant elbow, then the overall quality of the house will have to hit 12 points. Why do the sewage pipes need such elbows, because the elbows will store water so that the smell from the lower pipes will be blocked under this layer. Without an elbow, the laundry outlets and toilet drains emit a odor. There may be developers who think that the use of deodorant floor drains will work. The practice of the project proves that deodorant floor drains are far from meeting actual needs. And because of this small place, it is often best to reflect the construction quality of the builders.
Special reminder: In general, the drainage pipes in the lower part of the bathtub have return traps, while other locations do not, and it is necessary to install deodorant drains! ! !
Tip: Equipotential protection devices are mainly used for leakage protection in relatively humid environments such as kitchens and bathrooms. Metal racks, such as wash basins, have stainless steel sewer pipes. They are connected to a stainless steel pipe and are connected to a box with a wire (not less than 4 square feet) to prevent leakage due to moisture. Protective effects. In the high-end decoration are mandatory, almost everyone in the home improvement did not notice this point, and then there is a nut under the cast iron bathtub, but also for the wiring here, so the equipotential box should not be sealed.

Globe Valves and angle valves are designed for throttling or regulating flow in commercial and industrial applications. Bronze, cast iron, or cast ductile iron materials. Threaded, flanged, or solder end connections.
Angle valves for use in commercial and industrial applications. Typical services include hot and cold water, HVAC, steam, compressed air, gas and other general utility services.
Vacuum angle valve is used for turn on or shut off the airflow in the vacuum pipeline, the applicable media is air and non-corrosive gases.
It has two structures, one is angle type and another is a 3-way type within an ISO-KF or ISO-F various flange end pre-pump port.
a) Small diameter (≤DN50) valve body are precision investment casting.
b) Large diameter (> DN50) valve body are molding shaped seamless steel or steel plate.
c) Bellows sealed structure can withstand 150ºCtemperature, metal sealed structure can withstand 450ºCtemperature.
d) Can install on any position to control the airflow in the vacuum pipeline, as an on-off valve purpose
