The most critical place for acceptance of new houses is hydropower projects. This is different from the fact that the walls, doors, and windows are small projects. Therefore, the acceptance of hydropower projects for new houses must master acceptance skills and should not be ignored by developers.
Water and electricity acceptance criteria
First, the acceptance of the water pipes
1. Acceptance prerequisites
The quality of water supply and drainage pipe materials and water pipe fittings must comply with the standards set by the current state, including the name of the manufacturer, the factory brand, the product certificate, and the warranty book.
2. Acceptance requirements
(1) The pipeline should be installed with special tools. The nozzle must be treated with a standard reamer on the aluminum-plastic pipe at the nozzle end to prevent damage to the inner double-layer guard ring of the copper joint. No leakage shall occur.
(2) All kinds of valve installation positions should meet the design requirements and be easy to use and maintain.
3, acceptance methods and common sense
(1) Whether the running direction of the water is correct or not can be determined by visual inspection according to the drawings.
Second, the acceptance of electrical and electrical appliances
1. Acceptance prerequisites
(1) Concealed wires must be laid with PVC sleeves or iron pipes, and light or sheathing lines cannot be fed directly into the wall.
2. Acceptance conditions
(1) The discharge of the wire is horizontal and vertical, and it is fixed with a metal wire clamp. The wire connection box is fixed with metal sodium. There is no scar on the surface of the wire.
3, acceptance methods and common sense
(1) All electrical connectors connected to switches, sockets, leakage protection devices, distribution boxes and other electrical appliances should have a certain margin, usually 15cm.
The correct procedure for acceptance of hydropower
First, look first at the water pipeline. Water pipelines should meet the following requirements:
1. The pipelines are arranged in a rational and well-laid manner; switches and valves are installed smoothly.
2. Water pipes and accessories are tightly connected.
3, to ensure that the drainage pipeline is free, no obstruction, no leakage.
Second, look at integrated wiring. Check from four aspects:
1. All electric wires and conduits must be national standard products. The general power cords are divided into hard wires, cords, and sheathed wires. For ease of maintenance, the power cords should be sleeved.
2. The electrical wiring should be laid with a dark pipe. There should be no joints and kinks in the pipe. No twisting is allowed. It is forbidden to bury the wire directly in the plaster layer.
3, the pipe and wire are firmly installed, straight and smooth, tightly packed, and there is no joint in the pipe.
4, in line with the "phase line into the switch, zero line into the lamp" provisions, three-hole socket grounding wire should be laid separately, not mixed with the work of the zero line.
The third look at the water treatment.
1. All waterproof materials must comply with the requirements of environmental protection standards and related standards, and the products should have factory-qualified certificates.
2, brushing the surface of the waterproof layer of the grass-roots level, small uneven, loose, empty drums, sand, cracking and other defects, the moisture content should be less than 9%. Floor draining kitchen and all toilet floor waterproofing layer around the wall and should be turned up, a lot of 250mm above the ground, not pour water, water, 24-hour closed water test no leakage.
3, waterproof layer should be firmly bonded, no slip, edge, blisters, wrinkles and other defects; floor drains, pits, drains, etc. should be kept open, the construction of protective measures.
4, through the wall, floor, etc. have been firmly in good roots, should be protected during the construction process shall not damage the displacement; for all parts that are prone to voids to be finely processed to prevent leakage.
5, waterproof material must be uniform coating, no leakage coating, no damage, uneven thickness, etc., must be closed after the water pass the next process of construction.
Hydroelectric acceptance skills
I. About the acceptance of water
1, open the tap to see if there is water, how the water quality, whether there is a rust valve affect the water quality, can be replaced by the developer. Check each faucet and observe whether there is any seepage, leakage, or blockage in the upper and lower water pipes. It should be noted that as much as possible, let the water flow be a bit larger and anxious. Let's take a look at the water pressure and try the drainage speed.
2. Check whether the water meter has been installed, whether the water meter is empty, the valve is not closed tightly, the valve is off the wire, and the connector is dripping. The discovery of the empty water meter indicates that the meter is damaged or there may be a leak.
3, copy the water meter figures, this part of the water fee should not be borne by the owners. In addition to recording the data of the water meter, look at whether the water meter moves slowly when all the valves are closed and check whether there is any seepage or leakage in the upper and lower water pipes.
Second, on the acceptance of electricity
1. If there is electricity in the socket panel, it can be tested with the electric pen. Try to find out if there are any problems with all switches, sockets, and mains in the house. Pull down the socket switch in the main switch box. The indicator light is off. Test frequently several times to prove that the switch is well connected and the socket is safe.
2. Power off test. When the gate and meter are outdoors, they should check whether they can control the indoor lamps and the indoor outlets. After the gate is turned on, whether the indoor power is completely turned off; if the gate is open, the gates should also be checked separately. Control each branch line.
3, to see whether the electricity meter, electricity meter installation is currently more than 10 (40) A single-phase power meter, the operation is normal. Or fast or slow should be repaired. The number of meter readings used, because during construction, workers may use your energy, and the money is not the owner.
