Analysis: Water-saving faucet purchase tips and usage precautions
Government agencies purchase consumption of water-saving products to guide consumption, set an example for ordinary consumers to purchase water-saving products, and promote the overall market to develop more efficient and water-saving products, and ultimately form a trend of saving water in the whole society. Scope of application The product range applicable to this guide: the faucet (commonly known as the faucet) used in the cold and hot water supply pipelines in the building facilities, the water supply pressure is not more than 0.6 MPa, and the medium temperature is not more than 90. This guide does not apply to cast iron spiral lifts. This guide divides the faucet products into non-contact faucets, pedal faucets, time-delay self-closing faucets, ceramic nipples and other faucets. Water saving evaluation index To evaluate the water-saving index of the faucet, mainly consider its maximum water flow index and product life index, as shown in the following table. Non-contact faucet Maximum flow rate 0.15L/s (not applicable to bathtubs, washing machine faucets) After the off time leaves the use state, the water is automatically stopped within 2s. Switch life is 150,000 times 2. Pedal faucet Maximum flow rate 0.15L/s (not applicable to bathtubs, washing machine faucets) 300,000 lifespan (rotary outlet pipe life 80,000 times) 3. Delayed self-closing faucet Maximum flow rate 0.15L/s (not applicable to bathtubs, washing machine faucets) 1L of water per time 300,000 lifespans 4. Ceramic sheet sealing nozzle Maximum flow rate 0.15L/s (not applicable to bathtubs, washing machine faucets) 200,000 lifespan (single handle double control water nozzle > 70,000 cycles, conversion switch life of 30,000 times, rotary outlet pipe life of 80,000 times) 5. Other faucets Maximum flow rate 0.15L/s (not applicable to bathtubs, washing machine faucets) 300,000 lifespan (30,000 life of transfer switch, 80,000 life of rotary outlet pipe) Purchase route and identification method Various types of faucets can be purchased from manufacturers or dealers, but when purchasing water-saving faucets, you should look for the water-saving certification mark, and each water-certified faucet has a "section" attached to it. Word sign. Purchase prompt The inductive faucet automatically breaks water when the user removes the handle, which will save a considerable amount of water. The time-delay self-closing faucet can realize the quantitative water supply and save a lot of water. Gently try to open and close the faucet sealed by the ceramic sheet. If the hand feels very relaxed, the left and right sides are very smooth, then the porcelain core is hard and wear-resistant. A bubbler (filter) is installed in the nozzle, a general mesh nozzle uses a steel mesh, and a better bubble nozzle uses ABS (Environmental Engineering Plastics). In general, a good bubbler can effectively filter the sound of running water, more bubbles, and the water will not splash. Use suggestions Check the faucet frequently to see if it leaks. The telescopic nozzle should avoid breakage of the hose. If the amount of water flowing out of the nozzle is small and the water level is abnormal, it means that there is something in the filter at the nozzle of the nozzle, and the filter is removed, and it can be improved by washing it back. In the case that the water pressure is not less than 0.02 mpa, after using for a period of time, if the amount of water is found to decrease, or even the water heater is turned off, the filter cover can be gently unscrewed at the outlet of the faucet to remove impurities. , generally can be restored as ever. Do not use too much force on the switch faucet, and turn it gently, without much effort to screw it. In particular, do not use the handle as an armrest to support or use it. The showerhead metal hose of the bathtub faucet should be kept in a natural stretch state. Do not coil it on the faucet when not in use. At the same time, when using or not, be careful not to form a dead angle at the joint between the hose and the valve body to avoid breaking or damaging the hose.
