Good projects are based on good materials, especially hydropower projects. Some consumers choose low-quality hydropower materials in order to purchase electricity and water materials, but do not know that inferior hydropower materials may cause fire, run water, and other dangers. Experts believe that in the purchase of water and electricity materials, in addition to the selection of good water pipes and regular wires, water and electricity accessories can not be ignored.
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. Consumers are advised to use PPR tubes. 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.
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.
Consumers should not 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.
Circuit: check the package to see the copper core wire
Regardless of whether it is surface mounted or concealed, the materials used for circuit reconstruction generally include wires (plastic copper wires), telephone lines, television lines, network cables, audio cables, conduits, switches, sockets, and various accessories.
Now home decoration generally use single strand copper wire. Different power systems should choose different sections of wire. The general lighting system should select a wire with a cross-sectional area of ​​2.5 mm2; for an outlet system with air conditioners, disinfecting cabinets and other power greater than 1000 watts, a wire with a cross-sectional area of ​​4 mm2 should be selected.
The circuit reformation has the highest requirements on the quality of the wires, because poor quality wires can easily lead to short-circuit fires and other dangers. At present, there are many wire brands on the market, and prices are chaotic. It is recommended that consumers go to large supermarkets, factory outlets, or specialty stores to purchase wires.
When purchasing electric wires, first look at the “Great Wall Mark†and the production license number of the China Electrical Products Certification Committee on the outer packaging; then look at whether the plastic skin on the outer layer of the wire is bright in color and fine in texture. The normal wire should be ignited with a lighter. Open fire. Informal wires use recycled plastics, which are dull in color and can ignite open flames; they can also cut a head and look at copper core material. Regular red copper wire is used for normal wires, and non-formal wire copper cores are recycled copper. Copper is dark and hard.
Threaded pipe application of flame-retardant PVC pipe, with a foot gently step on the line pipe should not be flat. The best choice of accessories is the brand, the same material, and the same specifications. Weak lines, switches, and sockets, such as telephone lines and television lines, should also be purchased in the formal market.
Budget: Clever Planning to Reduce Waste
The type and quantity of hydroelectric materials are generally determined by the living appliances, water appliances, furniture placement locations and furniture dimensions. However, if the same living appliances, water appliances, furniture placement and size, if it is well-planned, it can avoid waste and save money.
The size of the furniture is best not to change at will, so as not to waste water and electricity materials. Taking a bedside socket as an example, if the 1.5 meter wide bedside cabinet is used to install the socket, if you change the bedside cabinet to 1.8 meters wide, it will cause some sockets to be blocked and cannot be used.
If you do not affect the beauty of your home, you may consider keeping the original switch, sockets, etc. of the house. If the original socket is located inside the cabinet, or behind the TV cabinet, the socket set behind the TV cabinet can be selected as the socket and socket board. TVs, VCDs, and stereos are often not plugged into the TV cabinet. Plugging directly into the socket will increase the power consumption. Selecting a patch panel with a switch not only reduces the number of sockets, saves money, but also avoids power. waste.
