There are some points to pay attention to in purchasing.
1. Check at the surface
Although the surface of each brand of spray hose looks similar, if you look carefully, you will find that the surface of the brand hose is flat, the gap is evenly distributed, the hand feels smooth, and the good quality of the spray hose adopts the stainless steel outer surface. The material quality has the advantages of not only protecting the inner pipe, but also playing a certain explosion-proof role.
2. Check at the material
Since we use cold water and hot water during bath, the shower hose plays an important role in connecting the shower and faucet. The use of hot and cold water all need to pass through the spray hose, so the requirements of the material of the hose are higher. Good shower hose should have good inner pipe material, not only to be over water non-toxic, but also to prevent scalding safety, but also to have good ductility, use to turn the flexible. When choosing shower hose, the shower hose can be stretched gently, and the contraction of the pipe body can be obviously felt, indicating that the material of the pipe has good toughness. Before purchase, you can consult the materials used in the guide tube, so as to avoid inferior products. The best material of the inner pipe of the hose is EPDM. The material has the advantages of aging resistance and heat resistance, and is not easy to expand and deform. The most important is that it does not contain six harmful elements of Rosh rules. Therefore, the internal pipe of ethylene propylene rubber is used safely.
3. Look at flexibility
Since we often pull the hose when bathing, so that we can bath or use it in different places, we should choose the flexible material when we buy the hose. For example, the flexible properties of hose made of EPDM are better. We are not easy to deform and recover to the original state when pulling. The outer pipe of the spray hose is made of 304 stainless steel, so the stability and flexibility of the hose are guaranteed.
4. Check at the tightness
Finally, we also need to see if it is closely connected to the interface between the shower and faucet and whether it is well sealed. If the sealing of the two ends of the hose is not good, we will easily leak in use, and there will be some safety risks. The quality of hose joint is made of all copper. The thickness of the interface and the solid washer inside are very durable. The appearance is also equipped with better rubber gasket, which has a good leak proof effect. Some hose ends are made of zinc alloy joints, which are cracked very simply. All copper and stainless steel joints are much stronger and more durable. There is also a small detail, namely, the gasket at the joint, which is usually divided into three types: plastic gasket, rubber gasket and silicone gasket. Most manufacturers choose rubber gasket, and there are few plastic gasket. The better is still using silicone gasket.
The service life of the hose is affected by various factors. In the long-term use, the cracks or burst will occur due to unstable water pressure and internal erosion. The water temperature also has a great influence on the hose. The high water temperature will harden the rubber material in the hose. After a long time, the hose will leak.
