There are many details of the decoration, bathroom water pipe installation is also a very important part of the water pipe installation is also a hidden project, the correct installation method to ensure the service life of the water pipe, to ensure the smooth follow-up work. The purchase of water pipe materials is also an aspect that can not be ignored. At present, there are a variety of plumbing products on the market, such as PP-R pipe, PVC-U pipe, plastic-lined steel pipe, stainless steel pipe, and copper pipe. Next, Xiao Bian also collected a lot of information to let everyone know about the installation of water pipes and the installation of toilet water pipes.
I. Preparation of toilet water pipe before installation
1. There should be a main valve in the water inlet. Before the installation, check whether the water pipe and connecting accessories are damaged, trachoma, cracks and other phenomena.
2. When installing kitchen and sanitary pipe, the size of the pipe on the wall should take into account the final size of the wall tile after it is attached, that is, the thickness of the wall tile is taken into consideration in advance.
3. In the wall and under the ground, use as few or no connection fittings as possible to reduce the potential for leakage. The connection fittings must be installed securely and without leakage.
4, the design of the water pipe should be taken into account with the faucet installation location of the washing machine, the layout of the water. At the same time pay attention to the location of the power outlet is appropriate. Put the drum washing machine in the kitchen cabinet to determine the size of the washing machine and the kitchen cabinet, so as to keep the position of the water.
Second, tap water pipe installation method
1, material acceptance
The quality of construction materials will directly affect the quality of the construction and the hidden dangers caused by poor materials used in the future. Before installation, the pipes shall be strictly inspected. The inner and outer walls of the pipes shall be smooth and flat, free from air bubbles, cracks, cracks, dents, peeling, and severe cold spots and obvious marks.
2, on the spot
The installer should carefully read the drawings to confirm the location of the water heaters, sinks, washbasins, washing machines, etc., and understand whether the owner or designer has special requirements. If there are special requirements, the construction should be done in accordance with the owner's or designer's instructions.
3, pipe cutting
In order to avoid unnecessary waste during the installation process, the installer should measure the length of the required pipe to cut it. The pipe cutting adopts special pipe shearing, and the bayonets of the pipe clip should be adjusted to match the diameter of the pipe to be cut. When rotating and cutting, the force should be evenly applied. When the pipe is broken, the section should be perpendicular to the pipe axis. After cutting, the entire round section of the fracture should be cut. No glitches.
4, pipe connection
The water pipes are connected with pipe fittings by means of hot melt, the hot melt connection is the most reliable, the operation is convenient, the airtightness is good, and the interface strength is high. Before connecting, remove dust and foreign matter from pipes and accessories. The pipeline connection uses a fusion splicer to heat the pipe and fittings. The depth and time of heat fusion of the pipe and fittings should meet the requirements. Do not rotate while welding. When the tubing is connected, the raw material should be wound to ensure sealing.
5, fixed pipeline
In order to ensure that the water pipes will not be resonated due to water pressure in the future, all water pipes must be fixed with a pipe clamp. Pipe clamps with 400mm to 500mm clearance, outer diameters below 25mm, pipe corners and water meters, and 100mm pipe terminations. If the water pipe is in a special situation, the thickness of the mortar must be >100mm. Pressure check point
After the installation of the water pipe, the pressure test shall be carried out. After all the installed inner wire bends, bulkheads or triangular valves shall be installed to ensure the seal. Water pipe pressure test is to ensure the quality of the water pipe and installation quality test, water pressure measurement using the pressure pump to enter the pipe into the pressure ≥ 0.6Mpa (some manufacturers in order to reflect the quality of their own brand pipe, the proposed pipe pressure 0.8Mpa.), pressure measurement time Not less than 30 minutes, pressure drop <0.05Mpa. When installing the water pipe, it should be horizontal and vertical, left and right cold, spacing ≥ 30mm. Hot and cold water pipe spacing is not less than 150mm. Hot and cold water pipes can not be worn together with a hole, they should be opened separately. When the water supply pipe and the gas pipe are applied in parallel, the distance is ≥50mm, and the cross-laying distance is ≥10mm. When the balcony needs to install a water pipe, a water valve should be installed.
Third, the water pipe what material is good
What we call safety durability means that no water leakage, burst or other life-threatening and home-safety events occur during the service life of water pipes, and long-term use can be guaranteed.
This requires the water pipe to be resistant to corrosion, high temperature, frost resistance and good mechanical properties. The comparison found that plastic pipe can not be high temperature resistance, in the case of large temperature difference is easy to deformation caused by leakage, and its small pressure resistance, easy to embrittlement, these are destined not suitable for long-term heating, not suitable for use in cold northern Is not suitable for high-rise buildings.
Composite pipe combines the advantages of metal and plastic, but precisely because of the different expansion coefficients of plastic and metal, long-term use will inevitably lead to delamination of the pipe, causing harm.
PP-R and copper pipes can be buried in walls
We all know that plastic pipes are extremely convenient to install, but most of the parts connected to them are metal parts. Because the mechanical properties of plastics and metals are very different, they can easily cause bursts or leaks. Therefore, they cannot be buried in the walls during construction. Can only be laid outside. The PP-R, brass and its accessories and specifications are complete and can be selected from 6mm-250mm. PP-R pipe can be welded seamlessly, and manufacturers can also be buried in the wall when installing. Its advantages are that the price is cheaper and the construction is convenient. The cutting, bending and processing welding of copper tubes are also simple, and the connection forms are various. There are brazing, ferrules, crimping, plugging, flanges, grooves, etc., which can fully meet various occasions and situations. need.
Copper tubes can inhibit the growth of bacteria
The main components of plastic pipes are some high-molecular polymers, which have certain toxicity and are relatively easy to infiltrate. Especially if they are used in direct drinking water supply systems, they have serious harm to the human body. Another example is the water pipe that you have not used for a long time. When you suddenly open it, you find out that the outflow is “yellow†water. In the past, the galvanized iron pipe in the house was prone to such a thing. This “yellow†water is also harmful to the human body. Copper pipes can inhibit the growth of bacteria. E. coli can no longer reproduce in copper pipes. More than 99% of E. coli and pneumococcal bacteria will eliminate themselves after entering the copper pipes for 5 hours, maintaining the cleanliness of drinking water.
Fourth, bathroom water pipe selection method
First, according to the needs of the formal building materials market to buy, so that the quality of water pipes is more assured.
Second, check the surface of the water pipe to see if its appearance is smooth and even, you can touch it with your hand to see if it is delicate; at the same time, look at whether the pipe is marked with the manufacturer's anti-counterfeiting label. If not, it is best not to purchase it.
Third, look at the color of the water pipe, high-quality stainless steel water pipes are generally silver and white, black and white are generally not pass acid-base passivation treatment, easy to scale. The quality of the PPR tube is generally matt white, and there will be no variegated particles. If the color of the water pipe is mixed with some variegated colors, it means that the quality of the water pipe is not good.
Fourth, plastic pipe to smell the smell of water pipes, if the water pipe has a stimulating odor, it shows that the quality of water pipes is not good, high-quality water pipes will not have a stimulating odor.
Fifth, metal pipes should pay attention to the connection method, home use generally simple self-locking spring type connection.
Quality determines water quality
"The water quality is good, the key is to look at the pipeline." Traditional galvanized pipes are apt to rust, corrode, and prone to fouling. They are prone to microbial growth, produce secondary pollution, and threaten human health. We often have such experience, no one in the family for a few days, open the tap, and shed yellow rust. This is the best example of pipe pollution of water quality. Household drinking water pipelines are mainly used in drinking water pipelines because of their corrosion-resistant scaling characteristics. However, due to the fact that plastics are easily doped to make false, secondary pollution is serious. Therefore, if conditions permit, try to choose stainless steel water pipes or copper pipes.
Summary: The relevant information on the installation of toilet water pipes has been introduced here for everyone. I hope this article will be helpful to everyone. If you still have something you don't understand, you can leave a message to Xiaobian at the bottom. We will answer your questions as soon as possible.
