Friends, for everyone who is considering no-name parts made in China (I am not dissing China, they make some great products, I am really talking about low end), think twice. Be it cartridges, faucets or anything else.
We just recently installed a water filter at customer's place. They wanted to use their own faucet, which suited their kitchen design. From outside, the faucet looked well quality made. Few days later, they notice smell in their water and it gets worse and worse every single day. Of course their first idea that something is wrong with the filter. We are equally worried, but ask them to disconnect the faucet and try the water directly from the filter. Turns out that faucet gives this bad smell, taste and even some film once the water is boiled.
We had similar experience with 2-in-1 faucet. It is made by large Chinese manufacturer, who makes faucets for many well known brands. Never issue with the faucet itself, however, it has flexible lines, one of them being for drinking water. Of course they do not manufacture but purchase them from a vendor. This vendor changed something on their side and one batch of faucets we received gave rubber/plastic smell to the water. Took us long time to track down the issue, change the line, report to the faucet factory.
Actually, it is good when the component gives bad taste or smell, at least you can know that something is wrong and identify it. What happens if there is no taste? If the faucet is leaching lead or the cartridge is leaching silver, you will not know it, you will not taste it.
There are usually alternatives to buying generic made in China water filter parts, and even very budget alternatives, either from known brands who control the quality, or from Taiwan/Korea/Europe/USA. This only applies to components that touch water, so mainly cartridges, faucets, tubes/lines and housings. Again, do not get me wrong, I am not saying they do it on purpose to poison you. They often have no desire or ability to control everything down to raw materials of every vendor they work with. They operate in a highly competitive environment where they need to cut cost to survive.
Thanks for sharing! However, how could a normal consumer know that a product's part is make in China, but marketed/assembled in USA and brand it as "Make in USA"?
