Perhaps,many wholesalers don't check their products quality by themself,if problem comes,you may will lost your time and money.
Perhaps,many wholesalers don't check their faucet products quality by themself,just ask their suppliers to do these,if problem comes,you may need to return to your faucet supplier,and change new some,that will lost your time,why not check the products before you received it?Like faucets,there are many things you should know about.
(of course,you can't check it just at home,because it need some special test equipments).
Maybe the next checking list is boring,but that is what we have to do before shipment,to ensure each of our products is in good quality.
(PS. Also you can set the QC standard to your supplier,that may be easier for you. :) )
1.Appearance quality
Surface plating for the spaut should be in good combined treatment. Organizations should be meticulous and looks sharper and curves smoother.Polishing surface should be brightness and without bubble,burns,dislocation and scratch defect.

Show you the hot an cold faucet working principle in one minute
Faucet is a great invention that we use every day,but what is the internal structure of hot and cold faucet?Do you know which parts will be used when it is working?
China faucet manufacturer distribution
Now more and more wholesalers or builders are purchasing faucets from China,for the price or the quality,but,do you know where to buy the faucets in competitive price and quality in china?
The Critical Role of Valves in Faucet Performance
Valves are the heart of any faucet, playing a pivotal role in managing water flow and ensuring durability. A high-quality valve not only enhances the faucet's functionality but also extends its lifespan. In the realm of certified faucets, such as those with the Uniform Plumbing Code (UPC) mark, the valve must meet stringent standards, with brands like Sedal often setting the benchmark for quality.
