Notes on water and electricity acceptance Let’s talk about things about water and electricity acceptance

In the decoration industry, water and electricity decoration is the most common, and water and electricity decoration is also necessary at home. After many home owners and friends have completed the water and electricity decoration at home, they have to inspect and accept the water and electricity projects to see if the water and electricity projects are qualified. Qualified. Generally, when it comes to water and electricity acceptance, many owners and friends don’t know how to go about it, or even what things should be paid attention to during water and electricity acceptance. So next, the editor will share with you in detail the precautions for water and electricity acceptance. I hope it will be helpful to everyone.

Precautions for water and electricity acceptance

Preparation for water and electricity acceptance

1. Tools?

Simple pressure test tools. Test tools include pressure test pumps , flow wrench, hexagonal outer wire, raw material tape, plug, etc. The picture on the left is a 30cm square simple pressure test tool, including a jack, pressure gauge, water tank and connecting hose.

2. Preparation

(1) Use a hose to connect the hot and cold water pipes to be tested to form a circle. The pressure at this time is 0.

(2) Seal all water outlets except the lowest outlet of the pressure test pipe tightly with plugs. It is recommended to use solid and durable copper plugs and other metal plugs.

Water acceptance process

1. Pressure test

(1) Open the water inlet valve, slowly fill the water from the lowest outlet of the pipeline, and fully discharge the gas in the pipeline Tighten the pressure test pump switch.

(2) Close the main water inlet valve, slowly increase the pressure on the pipeline, and after increasing the pressure to the specified test pressure, observe whether the joints and plugs are leaking.

(3) Welded pipes such as PPR, aluminum-plastic PPR, and steel-plastic PPR should be kept for more than 30 minutes, and non-welded pipes such as aluminum-plastic pipes and galvanized pipes should be kept for 4 hours. At the end of the test time, if the pressure drop does not exceed 0.05MPa, it is qualified.

2. Water pressure relief? After confirming that the pressure test is qualified, connect the pipe end to the water distribution fittings, supply water at working pressure, open the water distribution fittings in batches, and check whether each water outlet is smooth.

Electrical acceptance process

1. Inspection? Check whether the intercom and emergency call button of the house are normal, whether the doorbell is normal, the safety of the insurance socket, and the TV broadband socket, including Number and safety of bathrooms, kitchens, living rooms, bedrooms, etc.

2. What is the safety of the electrical circuit switch box? The safety and convenience of the electrical circuit. According to regulations, the number of circuits in each house should not be less than 5. The switches in the switch box are firmly installed and can be moved to check whether they are loose. Phenomenon. Each branch switch in the switch box should be clearly marked. If not or unclear, correct it immediately during renovation.

3. Test the socket panel with an electric pen? Use an electric pen to test the socket panel to see if there is any problem. If there is any problem with all the switches, sockets and main valves in the house, pull down the socket switch in the main switch box to indicate The light goes out and several frequent tests prove that the switch and wiring are in good condition and the socket is safe.

4. Pull the valve to cut off the power test? If the switch and electric meter are outdoors, you should check whether they can control the indoor lamps and indoor sockets. The method is to check whether the indoor power is completely cut off after the switch is pulled; If there are branch circuits, you should also check whether each branch circuit fully controls each branch line.

5. Check whether the electric meter is powered on.

Currently, most electric meter installations are 10(40)A single-phase electric meters. Check whether they are operating normally. Whether it is fast or slow, it should be reported for repair. Read the usage amount of the electric meter, because during construction, workers may have used your energy, and the owner should not pay for this money.

Notes on acceptance of hydropower decoration

1. The test pressure should be 1.5 times the working pressure of the pipeline system, and shall not be less than 0.6MPa. The pressure value is generally between 0.6MPa-0.8MPa , bigger is not better, nor is pressurization time longer.

2. Pipes buried in the floor surface and walls must undergo a hydraulic pressure test before sealing.

3. During the pressure test, the pipes should be fixed, the pipe joints should be exposed, and the water outlets of the pipes should not be connected to water distribution equipment.

4. For pipes connected by hot melt, the hydraulic pressure test should be carried out 24 hours after the pipe installation is completed.

5. Other reasons for unqualified testing: the plug is not installed properly, and the stop valve type main water inlet valve has quality problems.

The above is what the editor has shared with you in detail about the things to pay attention to in the acceptance of water and electricity. We hope that everyone can better understand the things to pay attention to in the acceptance of water and electricity through our sharing.

Water and electricity acceptance is very important, and it is also necessary to ensure whether the water and electricity at home are safe and whether there are any problems. Prevent problems from occurring when using it in future life. In addition, the biggest issue in water and electricity acceptance is whether the functionality is perfect. We have shared the precautions for water and electricity acceptance in great detail. We hope it will be helpful to everyone.
