Difference between high and low faucets
1. Test the water to see if the sealing performance of the faucet leaks. If the faucet head does not leak under the high pressure of 2.5Mpa and the low pressure of 0.05Mpa, it is OK. 1.2Mpa refers to the water pressure.
2. Low-pressure faucets are generally used in the British market because the water pressure there is relatively low. This kind of faucet has special requirements for water flow, one is that the valve core hole is larger, and the other is that the outlet nozzle has no net wire, so as to minimize obstacles and increase flow.
The main difference is naturally the valve core. High pressure requirements generally bear more than 20 kilograms of water pressure. Low-pressure faucets need water, which is generally required by Britain in Europe. The valve cores sold by some manufacturers are all rotten goods, the shells are all recycled materials, and some are cracked when boiled with boiling water. The quality is poor.
How to choose the right faucet;
1, depending on the material: generally according to the quality grade, there are titanium alloy products, copper chrome-plated products, stainless steel chrome-plated products, aluminum alloy chrome-plated products, iron chrome-plated products and so on.
2, look at the valve core: the valve core is the heart of the faucet, and the ceramic valve core is a good valve core. The products with better quality are all made of ceramic valve core, which has the characteristics of strong wear resistance and good sealing performance, and can generally be used for more than 300 thousand times; Low-grade products mostly use seals such as copper and rubber, which have short service life but low price.
3. Look at the coating: in chrome-plated products, the coating thickness of ordinary products is 20 microns, and the material is easy to be oxidized by air after a long time, while the coating thickness of copper chrome-plated with exquisite workmanship is 28 microns, with compact structure, uniform coating and bright and smooth color, which can keep bright as new after long-term use.
4, look at the appearance: it can be integrated with the style of basin, bathtub and bathroom, which plays the role of finishing touch.
5, practical: most imported brands are titanium alloy or copper chrome plating, and the "color face" is crisp and exquisite, but the price is expensive; Domestic brands of copper chrome plating are relatively affordable, and stainless steel chrome plating products are cheaper.
