1. Check whether the tube body and the electroplating layer on the surface of the shower head are smooth and smooth. This is because, in humid environments such as toilets, the surface of the shower is generally chrome-plated, but the same is chrome-plated, and the process treatment is very different. A good tube body is made of all copper material, and the surface needs to be polished, polished, dust-removed, nickel-plated, chrome-plated, etc., to ensure that it will not become black and bubbling during use. Generally speaking, it is from the surface of the shower. Look, the brighter and finer the naked eye can see, the better the coating process is.
2. Hold the tube body in hand to determine the quality of the material. The same is a chrome-plated shower. Some unscrupulous merchants will use cast iron pipes to pretend to be all copper pipes. A simple way to determine is to hold the pipe body with your hand and release it after 2-3 seconds. If there is fog on the pipe body If it stays for a long time, it is likely to be a cast iron pipe. If there is almost no change in the pipe body after the hand is left, it can basically be judged to be a copper pipe. In addition, the knocking sound of the copper tube is crisp, and the sound of the cast iron tube is low and dull. Knocking is also a way to determine the material of the shower tube.
3. Whether the quality of the shower is good or not, the invisible place is the most important, so be sure to ask the merchant about the material and service life of the switch spool of the shower. The shower switch spool is made of ceramics with extremely high hardness that has been fired through an extraordinary process. The service life must reach the national standard of 200,000 times. Life causes inconvenience.
