How to check and accept hydropower projects?

As a hidden project in the home, hydropower project will bring inconvenience to the later stage once there is a problem. Therefore, in the process of renovation of new houses, the acceptance of water and electricity must be especially careful! I. Waterway acceptance 1. Turn on the tap to see if there is water, how is the water quality, and whether there is rust on the stop valve that affects the water quality. You can ask the developer to replace it. Check each faucet and observe whether the upper and lower water pipes are leaking, leaking or blocked. It should be noted that the bigger the water flow, the more urgent it is. One is to look at the water pressure, and the other is to try the drainage speed. 2, check whether the water meter has been installed, whether there is a water meter empty. The valve is not tightly closed, the valve is out of line, the joint is dripping, and so on. It is found that the water meter is empty, indicating that the water meter is damaged or there may be water leakage points. 3, copy the water meter figures, this part of the water fee should not be borne by the owner. In addition to recording the data of the water and electricity meter, it is also necessary to check whether the water meter moves slowly when all valves are closed, and check whether the upper and lower water pipes are leaking or not. 4. Does the toilet run smoothly? Is the flushing sound normal? Is the water tank working properly? Many toilets will be blocked or blocked by construction waste. 5, waterproof, this is a place that is prone to problems, and once renovated, the responsibility is not easy to identify, so you must do a waterproof test when inspecting the house. First, visually check whether the leveling layer is 30mm and whether the shower room wall is waterproof 1800mm or more. 6. Do another closed water experiment. Use cement mortar to build a U-shaped threshold of about 10cm around the door, block the drain such as floor drain and fill it with water (only 2 cm at the highest point), and go downstairs to check it after 24 hours. This test is best carried out at the same time as the upper-level residents, so that the top floor and floor of their own bathroom can be tested at the same time. Toilet drainage, just shallow (about 2cm high). Then make an appointment for the owner downstairs to check the smallpox in his toilet 24 hours later. 7, floor drain and flashing slope comply with the design requirements, not flashing, joint tight smooth, no leakage. You can put the ping-pong ball on the ground. It would be nice if the table tennis rolled to the floor drain. When testing, remember to check from multiple directions. 8. Top-level households check the rain. If you buy a top floor, be sure to check how waterproof the top surface of each house is and whether there are any signs of rain leakage. Because according to the requirements of building construction, the delivered house has either passed the "test" of two rainstorms, or the construction party has carried out a rain experiment under the supervision of the supervision unit. Second, regarding the acceptance of the circuit 1, whether there is electricity on the socket panel, it is ok to use electricity for a written test. Try all the switches, sockets and master switches at home. Pull down the socket switch in the main switch box, and the indicator light goes out. Frequent tests prove that the switch and wiring are good and the socket is safe. 2. Power failure test. When switches and meters are outdoors, check whether they can control indoor lamps and sockets. The method is whether the indoor power supply is completely cut off after the switch is turned on; If there are switches in the room, you should also check whether each switch completely controls each branch line. 3. See if the electricity meter is electrified. At present, most electric meters have installed 10(40)A single-phase electric meters, which are running normally. Either it's fast or it's slow. The number of meters used for copying, because during the construction process, workers may use your energy, and the money should not be paid by the owner. 4. Generally speaking, the cross-sectional area of lighting line is 1.5mm, that of ordinary socket line is 2.5mm, and that of air conditioning line is 4 mm.. Test whether the socket is electrified with a professional shaking table or small appliances, and pay attention to whether the air conditioning hole and air conditioning socket match the outdoor air conditioning seat. 5, socket should also test whether the insulation to the ground is good, whether there is a grounding device. The zero ground voltage should be less than1v; ; If it is equal to 0, then it may be that zeros are connected together. 6. Usually fires are caused by electrical accidents, which has a considerable relationship with the setting of electrical circuits. In order to use electricity safely and conveniently, the number of loops per household should not be less than 5. 7. The switches in the switch box should be installed firmly, and each switch should be checked by shaking. If it is found to be loose, it should be tightened or replaced. Otherwise, it will cause greater danger when there is poor contact and fire in future use. Each branch switch in the switch box shall be clearly marked. If there is no or unclear, correct it immediately when decorating. 8. Check the cable TV socket, broadband socket and plug for looseness or unplugging. Check the number of weak current sockets, especially don't forget to open the line interface of telephone and TV, and pull it hard to see if it is dumb. 9, check the visual intercom, emergency call button is working properly. 10. Check the doorbell of the entrance door: test the doorbell with two No.5 batteries. Ring or not. 1 1, a safe socket for protecting children. In order to prevent children from putting their fingers into the socket holes, all sockets 30 cm above the ground must be equipped with safety devices. 12, there are many rules for toilet sockets. The power socket in the bathroom should be moisture-proof and splash-proof. The lighting seat in the bathroom must be a magnetic mouth safety lamp holder, and there can be no socket above the washbasin.
