No order, think of which to write, completely random
1, switch panel installation
A wall switch is divided into three parts: bottom box, panel, panel cover, we do plumbing remodeling, you need to pre-buried the bottom box in the wall, and then latex paint brushed before installing the panel and panel cover.
The acceptance criteria for switch panels, the most basic is seamlessly flush with the wall, but really the whole house panels are perfect to do it is difficult, many people's homes will appear in the same row of panels are not in a straight line, it is a tilted situation.
Or there is a gap between the panel and the wall, the panel cover.
To make the installation of the switch panel perfect, first of all, the workers have to make the wiring box stay on a horizontal line when installing multiple bottom boxes side by side, so that the panel and the panel cover can be parallel.
Secondly, the same batch of switch panels, some have gaps, some do not, and the quality of the panel has nothing to do.
The panel has a gap, mostly because the paint is not good. Panel cover has a gap, mainly because the wire box in the wire too much, the wire is too long, or the electrician did not organize the wires, screwed the panel will be up, the panel cover up naturally mounted on the uneven, there will be gaps.
These details of the problem especially affect the texture of the decoration, in fact, as long as the electrician careful some will not appear.
2, cable
Installation of the cable I encountered a strange operation (below), I do not know is not enough to buy the cable panel, or the electrician whim, actually directly in the blank surface of a round hole, the cable pulled out.
ABB: I designed the blank surface so smooth and good-looking, just for you to open the hole?
3, concealed light slot
Many designers like to use line lights when designing, this kind of light on the wall, on the top or on the ground can be shaped into a better shape and sense of line, the work of the installation used very much.
But if used in home furnishings, the construction details and requirements are higher. First of all, to ensure that the wall is vertical and flat, if the wall is poor flatness or poor verticality, you need to do wall correction, and then according to the width of the lamp slot with nine percent board or woodworking board to do the grass-roots level, to ensure that the lamp slot is completely embedded, and slightly higher than the wall, such as wall putty scraping and sanding is completed, the height of the lamp slot cover plate and the wall is completely flush. Otherwise it might look like this.
4, light position
Light position must be determined in advance and workers to determine the accuracy of this is the electrician is most likely to ignore and one of the most prone to error, because many electricians or foreman have a problem, is not love to look at the construction drawings, will be habitually based on their own experience to install, such as the whole room in the center of the room, the light position = bed, etc..
These are more common light position error, light position error is not only difficult to see, and because the top of the light is generally sprayed latex paint and then start to install, light position installation error means that the wall top paint must be re-sprayed, a mistake two processes rework, it is a waste of time.
5, bath heater, air heater position
Kitchen and bathroom ceiling choose gypsum board owners more and more, gypsum board compared to the integrated ceiling is more difficult to repair, so will be in the gypsum board on the ceiling reserved access port. But access ports, air heater, kitchen cooler installation and lighting must maintain symmetry to look good, such as the following picture is not symmetrical is very ugly.
And the installation must avoid the keel. If you do not pay attention to this problem when the ceiling, the ceiling will find that the opening will be opened on the keel, such as the following picture.
6, open and approved power
Slightly more professional designers will be in the design of the electrical design of the circuit, open the grouping, each group of open the control power and so on. However, most of the decoration companies and plumbers, will not go through a strict accounting, electric line diameter is based on experience, each group of open control area is also based on feeling.
For example: a group of kitchen, living room outlets, a group of other bedroom outlets, air conditioning a group, etc., there is no power to calculate the power consumption is very clear, and there is no detailed accounting of how much the open air, how big the diameter of the wire. This situation if the home appliances are not much, that is not a big problem, but if the power of electrical appliances, that once some places with more power than the load, there will be a trip, if all the appliances in the home to use more than the total power, but also may result in the use of electricity safety.
For example, in the picture below, this is the air conditioning power is larger, the current exceeds the limit of the air switch, so change the air switch.
Of course, the air conditioning is not randomly replaced, generally speaking, the indoor air openings can not exceed the total air openings into the home (63A), if more than to apply to the power supply bureau to increase capacity.
In summary, the circuit of the air and power is to be strictly calculated, can not be based on the feeling of chaos, the following are some of my statistics of the power of household appliances, we are interested in their own home against the calculation.
7, faucets, showers pre-cryptic (pre-buried)
Hidden faucets or showers before the more niche, now slowly accepted by more and more people, but hidden faucets and showers need to be pre-buried, after tiling will only be leaking out of a plumbing interface, so the pre-buried pipeline must be completely flat, and the pre-buried dimensions can not be too deep or too shallow, otherwise the installation of the water after the installation of the water interface. Too shallow, or the faucet and shower after installation may be crooked or not up.
If the home to do hidden faucets or showers, I recommend that we look for some good technology to rely on some of the plumbing master, or it is easy to accident.
8, ppr water pipe with a smooth elbow than with a right-angle elbow through the water more smoothly
ppr water pipe with a smooth elbow (big elbow) than the right-angle elbow has less damping, more favorable to the water pressure and flow rate.
Most of the water line remodeling with a right-angle elbow, resulting in the farther away from the water heater outlet water pressure will gradually weaken, hot water pipe in particular, some bathroom shower water pressure is insufficient, is not necessarily a problem of water pressure, it is likely to be the problem of the elbow, because the right-angle elbow is more expensive, it is recommended that you can add a little money to change into the downstream elbow (big elbow), the water pressure will be a little more powerful than with the right-angle elbow.
9, live wire process (threading)
Now most of the homeowners plumbing and electrical remodeling pursuit of horizontal and vertical, resulting in wire pulling (live wire process) is a joke.
Decoration companies or many construction teams have taken the plumbing horizontal and vertical as a standard in the publicity, but also said that the wire as usual can be pumped. Actual in the construction process simply can not reach, and even a lot of even the construction of the smooth needs are wrong.
Live wire process is the ground wire cloth good line pipe, and then threading.
(emphasis: first cloth pipe and then threading)
A lot of plumbing master or foreman in order to catch up with the construction progress or figure construction convenience, are laying PVC wire pipe while threading. Many walls are also used yellow wax pipe. When the cement mortar to the wire groove laid, the line is simply impossible to pull.
And, some decoration companies in order to transform the plumbing look good, pvc wire pipe elbow with a right-angle bend, rather than a big bend, right-angle bend does look good, known as the cure for obsessive-compulsive disorder, but when a line has a three or four right-angle bends, inside the line with the wires is also basically dead. For example, the following picture of this line pipe, neat and tidy look good, but the line is definitely not out.
10, the cost
Water and electricity remodeling construction by the number of meters, but also in accordance with the points to calculate, there are also directly say a price.
But after all, there are industry barriers, many people simply do not understand.
So either way, you're probably going to be fooled.
Whether it's a partial or full change, the best way is still by the meter.
But there are two things to keep in mind.
1, plumbing
Wire is how a direction, is to go straight or horizontal and vertical, both the length of the pipe required is different, the price of the impact is also relatively large.
2, price
First of all, the labor cost, whether it is a large company or a small company, or construction team, in fact, the same construction standards, plumbers and electricians should be about the same, even if there is a price gap of up to two or three dollars a meter, and did not imagine so outrageous. The only thing that affects the price of plumbing and electrical remodeling labor costs is the construction standard, complex, the higher the construction difficulty, the higher the unit price, and vice versa, the price is slightly lower.
The second is the price of auxiliary materials, auxiliary material prices are not like the main material tens of thousands of tens of thousands of price difference is so obvious. Even if the plumbing and electrical remodeling with all imported wires, pipes, fittings, etc., up to half of the domestic. Domestic materials, the price gap between the major brands is not obvious.
So, there are decoration companies give you say, we material how awesome, how amazing, that at best is a marketing scheme or selling point only.
Lastly, I would like to advise the homeowners who are "crazy" about plumbing and electrical remodeling to say that you are afraid of being brainwashed, and add sockets and switches all over the place, which is actually not very useful, and you have to add them in useful places. Like those a flat apartment, buy switches and sockets panel can spend more than 10,000, two or three hundred panels of the Lord, admire you, mainly engaged in the renovation of the rare encounter a wrongdoer.
