What details should be paid attention to in the renovation of hydropower?

Now decoration companies are promoting the so-called "water and electricity standards". Whether this standard is controversial or not, it at least regulates the general direction of water and electricity threading, pipeline laying and pipeline direction, but the details are not considered by the designers of decoration company standards, let alone ordinary owners. Only the project personnel in the front line know that these details are what I want to talk to you today.

There is no order, write wherever you want, completely random.

1, switch panel installation

The wall switch is divided into three parts: bottom box, panel and panel cover. When we do hydropower transformation, we need to embed the bottom box in the wall first, and then install the panel and panel cover after the latex paint is painted.

The most basic acceptance standard of switch panel is seamless and flush with the wall, but it is very difficult to make the whole roof panel perfect. Many people will have the same row of panels that are not in a straight line and are inclined.

Or there is a gap between the panel and the wall and the panel cover.

To install the switch panel perfectly, first, workers should keep the boxes in a horizontal line when installing multiple bottom boxes side by side, so that the panel and the panel cover can be parallel.

Secondly, some switch panels in the same batch have gaps and some don't, which has nothing to do with the panel quality.

There are cracks in the panel, most of which have not been repaired with paint. There is a gap in the panel cover, mainly because there are too many wires in the box, the two ends are too long, or the electrician has not arranged the wires properly. After screwing in the screws, the panel cover will be jacked up, and the cover will naturally be uneven and there will be gaps.

These details especially affect the texture of the decoration, in fact, as long as the electrician is careful, it will not appear.

2. Network cable

I encountered a wonderful operation when installing the network cable (below). I don't know if I didn't buy enough network cable panels, or if the electrician had a whim, he actually opened a round hole on the blank surface and pulled out the network cable.

ABB: Did I design the blank face so smooth and beautiful just to open a hole for you?

3. Concealed lamp trough

Many designers like to use linear lighting when designing. This kind of lamp can create a better shape and line sense whether on the wall, roof or ground, and the tooling is used more.

But if it is used for home decoration, the details and requirements for construction are even higher. First of all, we must ensure the verticality and flatness of the wall. If the flatness or verticality of the wall is poor, it is necessary to correct the wall first, and then use Jiuli board or joinery board as the base according to the width of the lamp trough to ensure that the lamp trough is completely embedded, slightly higher than the wall. After the putty on the wall surface is leveled and polished, the height of the lamp trough cover plate is completely flush with the wall surface. Otherwise, it may become like this.

4. Lamp position

The lamp position must be determined accurately with the workers in advance, which is one of the links that electricians are most likely to overlook and make mistakes, because many electricians or foremen have a problem, that is, they don't like to look at construction drawings, and they will habitually install them according to their own experience, such as centering the whole room, lamp position = bed and so on.

These are common lamp position errors. The lamp position error is not only ugly, but also because the lamp at the top is usually painted with latex paint before installation. The installation error of lamp position means that the top coat of wall surface must be repainted, and it is a waste of time to rework two processes for one error.

5, Yuba, air warm position

More and more owners choose gypsum board for kitchen and bathroom ceilings. Gypsum board is more difficult to maintain than integrated ceiling, so inspection ports will be reserved on gypsum board ceiling. However, the installation and lighting of manhole, heating and kitchen cooler must be symmetrical to look good. For example, the picture below is ugly without symmetry.

And be sure to avoid the keel when installing. If you don't pay attention to this problem when you are hanging the ceiling, you will find that a hole will be opened in the keel after the ceiling is finished, such as the picture below.

6. Open and approve electricity.

A slightly more professional designer will check the circuit, open the group, the control power of each open group and so on in the electrical design. However, most decoration companies and plumbers will not go through strict accounting, the circuit diameter is based on experience, and the control area of each group is also based on feeling.

For example, a kitchen socket, a living room socket, a set of other bedroom sockets, an air conditioner and so on. There is no power meter to calculate electricity consumption at all, and there is no detailed calculation of how much space and wire diameter to use. In this case, if there are not many appliances at home, the problem is not big. However, if the electrical power is high, it will trip once the electricity consumption exceeds the load in some places. If the electricity consumption of all electrical appliances in the home exceeds the total electricity consumption, it may also cause electricity safety.

For example, as shown in the figure below, the air conditioner has high power and the current exceeds the limit of the air switch, so the air switch needs to be replaced.

Of course, the air conditioner is not changed casually. Generally speaking, the indoor air outlet cannot exceed the main air outlet (63A). If it exceeds, you should apply to the power supply bureau for capacity increase.

To sum up, the on-off and power of the circuit must be strictly calculated, and it is not possible to mess around by feeling. The following is the power of some household appliances I have counted. If you are interested, you can compare it with your own.

7. Pre-hidden faucets and showers (embedded parts)

Hidden faucets or showers used to be relatively small, but now they are gradually accepted by more and more people. However, hidden faucets and showers need to be embedded, and only one water pipe joint will leak after tiling, so the pipeline must be completely flat when embedded, and the embedded size should not be too deep or too shallow, otherwise the installed faucets and showers may be crooked or not installed properly.

If you want to make a hidden faucet or shower at home, I suggest you find a hydropower master with better technology and higher reliability, otherwise it is easy to have an accident.

8. ppr water pipes are smoother with straight elbows than with right-angle elbows.

The downstream elbow (big bend) of ppr water pipe has less damping than the right-angle elbow, which is more conducive to water pressure and flow.

The right-angle elbow is mostly used in waterway reconstruction, which leads to the gradual weakening of the water pressure at the outlet point far from the water heater, especially the hot water pipe. Some bathrooms have insufficient water pressure, which is not necessarily the problem of water pressure, but probably the problem of elbows, because right-angle elbows are more expensive. I suggest you add some money and replace it with a smooth elbow (big bend). The water pressure will be worse than that with a right-angle elbow.

9, live line process (threading)

At present, the horizontal and vertical pursuit of most owners' hydropower transformation leads to the dynamic of cable (live line technology), which is simply a joke.

Decoration companies or many construction teams regard water and electricity as standard in propaganda, saying that wires can still twitch. In fact, it can't be achieved at all in the construction process, and even many construction requirements are wrong.

Live line technology is to lay conduit first and then thread ground wire.

(Emphasis: Pipe laying before threading)

In order to catch up with the construction progress or facilitate the construction, many hydropower masters or foremen lay PVC conduits while threading. Many walls still use yellow wax pipes. Cement mortar trowel, unable to stay.

Moreover, the hydropower transformation of some decoration companies looks good. The elbow of pvc conduit adopts right-angle bend instead of big bend. Right-angle bend is really beautiful, which can be called curing obsessive-compulsive disorder. But when a line has three or four right-angle bends, the lines inside are basically dead lines. For example, the conduit below is neat and beautiful, but the line can never be drawn.

10, cost

Hydropower reconstruction construction is calculated by meter, by point and directly by price.

But after all, there are many industry barriers that people simply don't understand.

So, either way, you may be fooled.

Whether it is a partial reform or an overall reform, the best way is to calculate by the meter.

But pay attention to two problems.

1, water pipe

What is the direction of the wire, whether it is straight or horizontal, and the length of the pipeline required by the two is different, which has a great impact on the price.

2. Price

The first is the labor cost, whether it is a big company or a small company or a construction team. In fact, under the same construction standard, the charges of plumbers should be similar. Even if there is a price gap, it will be two or three yuan a meter at most, which is not as outrageous as expected. Only the construction standard affects the labor cost of hydropower transformation. The more complicated and difficult the construction, the higher the unit price and the lower the price.

Followed by the price of accessories, the price of accessories is not as obvious as the price difference of tens of thousands of main materials. Even if all imported wires, water pipes, pipe fittings, etc. Used for hydropower transformation, it will not exceed half of domestic production at most. Domestic materials, the price gap between major brands is not obvious.

Therefore, a decoration company tells you how awesome and magical our materials are. At best, it is a marketing routine or a selling point.

Finally, advise those owners who are "crazy" about hydropower transformation that you are afraid of being brainwashed, and it is useless to add sockets and switches everywhere. If you want to add it, add it in a useful place. Like those flat apartments, you can spend more than 10 thousand to buy switch socket panels. Two or three hundred panel owners admire you very much, and it is rare to meet a big head who mainly does decoration.
