Take a look: Check whether the body of the flush valve and the electroplating process layer on the surface are smooth and smooth. This is because, in the wet and cold natural environment such as the indoor space of the cabinet and bathroom, the surface of the flush valve must generally be treated with stainless steel, but the same is stainless steel, but the treatment process is quite different. According to the store’s detailed introduction, a good tube body is made of pure copper material, and the surface layer should undergo grinding and polishing, grinding and polishing, ash removal, nickel electroplating, stainless steel and other solutions to ensure that it is not easy to turn black and black during application, and bubbles fall off. , Generally speaking, from the surface of the flush valve, the brighter and more detailed the human eye can see, the better the coating process.
Second grip: Hold the tube body in your hand to judge the quality of the material. The same is a stainless steel shower head, and some poor shops will use cast iron drain pipes to fake full air-conditioning copper pipes. If the mist does not disperse for a long time, it is likely to be a cast iron drain pipe. If the pipe body basically does not change after the hand is removed, it can be basically judged as an air conditioner copper pipe. In addition, the copper pipe body is brittle and brittle, and the cast iron drain pipe is thick and clogged, and beating is also a way to judge the material of the flush valve body.
Three questions: As the saying goes, laymen watch the fun, and experts watch the doorway. The quality of the flush valve is the most important, and the invisible area is the most important, so be sure to understand the material and service life of the store’s valve core.
