Most reasons of why consumers choose reverse osmosis systems as home water purification units are because the RO membrane can filter off heavy metals such as Arsenic, cadmium, lead, chromium, zinc, copper, etc. People place importance on the filter cartridges and RO membranes when choosing reverse osmosis water purification units. However, there’s one more important accessory besides the filter cartridges and RO membranes, which is the accessory after the RO membrane. The water passed through the RO membrane is the pure water, and will be storage in the storage tank, the filter after the 5th step, and the faucet, so it’s important to choose these three accessories.
In this article, we will show you how the RO faucet is important to the RO system.
The RO faucets all looked the same, every faucet is shine and bright but in a big price range. Do you know the differences between each faucet?
Material: Most RO faucets and home using faucets are made of brass, but brass contains lead. Water can leach lead from the brass and drinking the water with lead is harmful to health. However, people nowadays put emphasis on health, so the market starts selling low-lead brass faucet or lead-free brass faucets. Different materials reflect on different price ranges.
Processing method: Copper is generally cast molding method (foundry) or forged, different processing method costs different, and there are differences in the finished product. Forging products are more detailed, and casting products are rough, this part shows in the inner side of the product, and can’t be viewed from the outward appearance, and the picture below shows the internal state of foundry molding products.
Stainless steel products are hard and with high melting point, it must adopt casting method processing, but machines are easily wear out, and it’s difficult to polishing. Therefore, the cost is a lot more products and more than copper.
Above mentioned points are why the RO faucets are looked similar but the prices are quite different. You may think that faucets all looked the same and are just the outlet for the water, why should we care about it? However, we want to tell you that faucets are not all the same and it’s important to know it.
Following picture is a low price RO faucet you can get everywhere in the market, the water will be storage in the sliced part of the picture, so every time you turn on the faucet, the first water come out from this place. If you use brass faucets as RO faucet, the water sitting in this part of brass faucet will leach high level of lead, and the water will not be filter again and goes into your body when drinking.
Lead is one of the heavy metals and it’s harmful to our health, and it can’t be remove from our drinking water by boiling, so if you choose brass RO faucet as the last part of the RO system, the RO membrane filtered water will be polluted again when passing by the brass faucet. Therefore, your drinking resource is not secured if the last accessory of your water purification unit is the faucet made of brass! We strongly suggest you that no matter what brand your RO system is, please choose lead-free stainless steel faucets for the system to secure the last defense line of your drinking water.
