Found a big hole in the early stage of renovation! If you are preparing to decorate, just installed, or like me, the developer brings its own water and electricity and then renovates, you must pay attention to the problem of neck reduction when the most waterway! Otherwise, it is very easy to cause you to have low water pressure in the later stage, which will not only be troublesome to take a bath, but also may not be able to use the smart toilet.
The new house comes with water and electricity, but the kitchen and bathroom do not have water
I don't have a lot of work, so I want to try to change the water by myself, after all, I do other projects by myself (smashing walls, painting walls, wooden floors), and I don't necessarily have a master to come to this job.
I did a lot of homework, and I finally got it done. After operating it myself, I also found that water is much more trouble-free than electricity, and electricity is too laborious, so the water is clicked and finished.
After the end, I accidentally found a big thing, these developers who cut off their own water pipes, and the necking inside is quite serious! I don't know what the other interfaces are buried in, and no matter how powerful it is, it will inevitably affect the water pressure!
This kind of concealed construction can't be seen without cutting, and it can't be found when suppressed, because the suppression is to see the leakage rather than the pass, and it can be suppressed and passed through if it is completely blocked.
In contrast, this is the invalid connector that I connected myself, is the difference between the two very big?
I remember that when I was doing my homework, the plumber came to repair the waterway, and the cut head was either completely blocked, or it was only the size of a needle's eye.
Why is it so bad? Because I did it myself, it's easy to judge why the diameter was reduced like this.
The best hot melt temperature of PPR tube is 260~280 degrees, and 265 degrees Celsius is the most suitable setting.
Moreover, the depth of the interface should be drawn like this before hot melting, so as to avoid the reduction of the diameter caused by multiple melting.
Because the temperature is suitable, the sub-mouth and the female mouth do not melt quickly, they are very hard, you have to press hard, slowly, wait 3 seconds after inserting to the end, and the time of the whole process from the beginning to the connection takes 2-30 seconds.
The qualified requirement is that the glue overflowing here in the seam is two layers, one layer of the sub-mouth and one of the female mouth, commonly known as double eyelids. One more layer or many more layers means that the hot melt is excessive, and the inside will be more or less necked.
Personally, I don't think it's a long process, but if you treat it as a job, it will definitely feel slow when you have more joints. The unreliable master will definitely adjust the hot melt machine very high, so that the dissolved fast plug is also simple, anyway, this kind of concealed construction, even if there is a problem, he can't find him, regardless of the depth of the slam plug will not shrink the neck.
Therefore, whether your home decoration is all-inclusive, half-package, or always accompanied, you must go to the scene on the day of the waterway, see if the master's hot melt action rules are not standardized, see if the connection is a double eyelid, and take a look at the opening in the half, and touch whether there is a shrinkage inside.
If you miss it, it doesn't matter if the waterway has been completed, all the sluices including the main gate of the property well are opened to the maximum, find a container for water testing, as long as 10 seconds can produce 2 liters of water, that is, it meets the minimum standard, there is no big problem.
If the water pressure is not satisfied, first look at the entire floor, whether the water pressure of the unit is the same problem, if others are okay with their own water pressure is low, then check the joints, if most of them are double eyelids, individual three or four layers of eyelids are suspected. If you can't see the joint if you are already buried, there is no good way, and it is estimated that you can turn off the sluice endoscope, but the waterway is a right-angle turn, and you can't go far, but you can also see the level of welding if you look at a few casually.
I really don't know if I don't want to learn, there are too many doorways, big pits and small pits in different industries, and if the house is decorated, the joints inside are all this and that.
In the next issue, I will share how I made this whole wall of hanging paintings by hand with waste wood strips and paper shells~Ps: The cost of each painting is only a dozen.
If you want to buy it, there are also finished products~
If you are interested in self-decoration or want to know how to check the quality of decoration, the content of slotting, water and electricity will also follow.
