1. Look at the material
When purchasing, it is best to choose copper products, which are heavier and have better quality, which can prolong the service life of the product. Do not buy zinc alloy products cheaply, otherwise it will be easily damaged.
2. Look at the valve core
When choosing a product, look at the core of the product. The quality of the core will directly affect the sealing and service life of the product. In addition, it is necessary to look at the sealing ring and the ceramic sheet, and try the feel of the product. Generally, the product with good softness has a longer service life.
3. Look at the gloss of the angle valve
When selecting products, look at the gloss of electroplating. Generally, good products have smoother surfaces and better gloss, while inferior products have poor gloss.
4. Look at the weight
When selecting products, you can weigh the weight of the product by hand. The weight of the product should preferably be greater than 180 grams, so that the wall thickness of the product is sufficient, and it is less likely to be broken during use.
5. Look at the function
When selecting products, the cold water valve should preferably have a water stop valve, so as to avoid the backflow of the toilet. The hot water valve should preferably be equipped with a diverter, which is explosion-proof and leak-proof, so that it is safer to use.
