No. The filters sold for faucet application are not certified to remove microorganisms removal from raw water to make it safe to drink. Even a reverse osmosis (RO) membrane isn't certified for microorganism removal to protect health. Although the RO membrane pore size is small enough to filter out parasites, cysts, bacteria, and viruses, there is always a potential for a breach in the membrane. To remove microorganisms from a raw water source you need to add an NSF/ANSI Standard 55 Class-A certified ultraviolet disinfection system.
Can you advise the model number? Most Bunn machines use a faucetwith a rubber membrane inside which is difficult to repair. Its simpler for the owner to replace the faucet with a new Bunn item. If I know the model I may be able to give you the part number you need
Inside the faucet is a rubber membrane and this has become detached from the handle. You can order a replacement faucet from the Fetco agent in your area. Swapping it out a simple process requiring only basic hand tools. Turn the machine off and remove the left side panel. Behind the side panel you should find a clear silicone pipe. Remove the bung in the end and drain water into a bucket or drain. Once level is low enough, you will be able to remove existing faucet and replace with new one. Reassemble, turn on machine and allow to fill and heat.
Check the capillary tube to make sure it is not plugged. This will restrict the flow from membrane. Also make sure the seal for membrane is not damaged. It takes several hours to refill the RO tank if it is empty. RJ
Green is the color it should be when producing GOOD (low TDS) water. A constant Red light indicates the TDS is high (relative to what the normal TDS rejection is on your water supply) and the membrane needs to be replaced. Frequently the TDS light will be RED when initially drawing water at the RO faucet because of a spike of TDS coming through membrane from static water in line. I suggest taking a sample of pretreated water and RO water to a dealer for a TDS test to see if the Membrane needs replacing. RJ
Try this open faucet to make sure water is flowing to the machine, then remove the pour over cover and pour in water until it flows through the sprayhead, then turn brewer on.
OK, now I understand. First, on the Reverse Osmosis Membrane Housing Outlet Ports there is only a Check Valve attached to the Permeate (Pure Water) Port, not the Concentrate Port (Drain Water). The Permeate line is what fills the storage tank, so you don't want back pressure from the tank reversing into the membrane filter which could severely damage it. So, there is a high Risk for Sewer Water to Back-flow into the Membrane Filter and Contaminate it as it is discharging water to the sewer drain if there is any noticeable pressure restriction in the drain distribution manifold. Second, this is why "Air-Gap" Faucets are supposed to be used when installing Reverse Osmosis Systems. With an Air-Gap Faucet, there are three (3) attachments for tubing at the base of the faucet, and a small hole drilled out underneath the lever or handle of the faucet. The 1/4" pressurized drain line tube from the RO System attaches to the 1/4" barbed fitting under the faucet base, then a 3/8" drain line tube attaches to the 3/8" barbed fitting. So when the drain water is pumped up to the faucet under pressure, it returns to the sewer line under Gravity, or No Back Pressure. Then, if the plumbing becomes restricted in any way that the RO Unit can't drain into the sewer under gravity feed, the hole drilled in the base of the faucet allows the back pressure to be escaped to the atmosphere, and if necessary drain water out of the hole until the plumbing pressure restriction can be resolved. This eliminates the possibility of a reverse flow pressure situation from occurring. Hope this helps, and you can always visit us online at www.puresafe.com We have filter cartridges for all makes and models of RO Systems, and 1/2 micron filters that no one else in the trade is using at this time.
