China faces increasingly strained water resources and a deteriorating environment. Government agencies can effectively reduce water stress and reduce the negative impact on the environment by purchasing water-saving products, thus achieving direct water conservation and indirect environmental protection.
Green Sun Faucet
As a large consumer group in the consumer market, government agencies will greatly reduce the cost of product use through purchasing and using water-saving products, thereby effectively reducing fiscal expenditure.
Government agencies guide consumers through the purchase of water-saving products, set an example for ordinary consumers to purchase water-saving products, promote the overall market to develop more efficient and water-saving products, and finally form a society-wide water-saving fashion.
Scope of application
This guide applies to the scope of products: installed in the building facilities within the hot and cold water supply pipeline, the water pressure is not greater than 0.6MPa, medium temperature is not greater than 90 °C under the condition of the water nozzle (commonly known as the faucet).
This guide does not apply to cast iron spiral jacks.
This guide divides tap products into non-contact faucets, foot-operated faucets, time delay self-closing faucets, ceramic seal faucets, and other spouts.
Water saving evaluation index
Assess water faucet's water-saving index, mainly consider its maximum water flow index and product life-span index, as shown in the following table.
1. Non-contact faucet
Maximum flow ≤ 0.15L/s (does not apply to bathtubs, washing machine taps)
After the off time leaves the state of use, automatic stop of water within 2s
Switch life ≥ 150,000 times
Foot pedal
Maximum flow ≤ 0.15L/s (does not apply to bathtubs, washing machine taps)
Lifetime ≥ 300,000 times (rotary outlet pipe life ≥ 80,000 times)
3. Delay self-closing water nozzle
Maximum flow ≤ 0.15L/s (does not apply to bathtubs, washing machine taps)
Each time the water supply ≤ 1L
Lifetime ≥300,000 times
4. Ceramic sealing faucet
Maximum flow ≤ 0.15L/s (does not apply to bathtubs, washing machine taps)
Lifetime ≥ 200,000 times (single-handle double-control water faucet> 70,000 cycles, transfer switch life ≥ 30,000 times, rotary outlet life ≥ 80,000 times)
5. Other water nozzle
Maximum flow ≤ 0.15L/s (does not apply to bathtubs, washing machine taps)
Lifetime ≥ 300,000 times (Transfer switch life ≥ 30,000 times, Rotary outlet pipe life ≥ 80,000 times)
Purchase channels and identification methods
Various types of water spouts can be purchased from manufacturers or distributors, but when purchasing water-saving spouts, they should be conscious of the signs of water-saving certification. Each water-saving water faucet is affixed with “festivalâ€. Word sign.
Purchase tips
Inductive taps automatically shut off water after the user removes the handle. This will save a considerable amount of water.
Time-delay self-closing water nozzle can realize quantitative water supply and save a lot of water.
Try to open and close the taps of ceramic seals by hand. If the handle is very easy, the left and right sides are very smooth, then it shows that the porcelain core has good hardness and wear resistance.
The water nozzle is equipped with a bubbler (filter), the general bubble nozzle uses steel mesh, and the better bubble nozzle is ABS (environmental engineering plastic). In general, a good bubbler can effectively filter the sound of flowing water, with more bubbles and splashes.
Use suggestions
Always check the spout for leaks.
Telescopic taps should avoid hose rupture.
If the amount of water flowing from the spout is small and the water level is not normal, it means there is debris in the outlet spout of the spout and the filter is removed.
When the water pressure is not lower than 0.02mpa, after a period of use, if the amount of water is found to decrease or even the water heater turns off, the filter cover can be gently unscrewed at the water outlet of the faucet. Impurities can generally be restored as originally.
Do not use too much force to switch the water nozzle. Gently turn it with a gentle turn. It does not take a lot of effort to screw it to death. In particular, do not use the handle as a handrail to support or use it.
The metal hose of the showerhead's showerhead should be kept in a natural stretch, and should not be coiled on the spout when not in use. At the same time, when using or not using, pay attention to the joint between the hose and the valve body not to form a dead angle, so as not to break or damage the hose.
