Home appliances can not be separated from the wires, especially the old houses, but the wires are small and “responsible†is significant. A lot of fires are caused by the aging of the power lines, their unreasonable configuration, or the poor quality of the wires used. Therefore, consumers must polish their eyes when buying electric wires, carefully identify them and prevent them from occurring.
Waterway: Choose PPR Tubes and Premium Accessories
Waterway construction materials include water pipes and a wide range of accessories. The water pipes are mainly divided into galvanized pipes, aluminum plastic pipes, PPR pipes, copper pipes and stainless steel pipes. Huang Xiangling, director of decoration engineering at Yuanzhou, advises consumers to use PPR. PPR pipe is non-toxic, light weight, pressure-resistant, corrosion-resistant, simple construction, and can be used as cold and hot water pipes at the same time. Because the interface uses hot-melt technology, the tubes are completely integrated, no aging leakage occurs, and the price is moderate.
Aluminium plastic pipe is also a kind of pipe material that is more popular on the market. It is light, durable and easy to construct. However, the material of aluminum plastic pipe is difficult to adapt to hot and cold changes. When used as a hot water pipe, long-term thermal expansion and contraction is easily damaged. Wall leaks.
Successful smart cabling
Galvanized pipes are pipes that the country has banned. Most of the old houses in Beijing used galvanized pipes. Galvanized pipes are apt to be oxidized and corroded, and easily generate a large amount of rust. As a result, the content of heavy metals is too high, which is harmful to human health. Copper pipes and stainless steel pipes are particularly resistant to corrosion, and they are high-grade pipes. The cost is relatively high. It is not necessary to use copper pipes and stainless steel pipes for ordinary home decoration.
Plumbing fittings include elbows, tees, direct heads, etc. Although the accessories are small, the expenditure is higher than the water pipes, and sometimes even exceeds 1/3 of the water pipe expenditure. Some consumers believe that as long as the quality of the water pipes is good, the use of a little accessory will not affect the quality of the project and it will save money. In fact, the construction of waterways has higher requirements on the quality of accessories. Take the connector as an example. If the joint is more than half a knurl, it will cause the joint to be twisted. The cracks that are often cracked are very small and difficult to find, so leakage is not known.
Huang Xiangling reminded consumers not to use quality accessories in order to save money. It is best to buy high-quality water pipes and purchase the same brand, same material, and the same specifications. If the funds for renovation are limited, a combination of ordinary water pipes and high-quality accessories can be selected.
