Review on WANFAN Kitchen Sink Faucet with Pull-Down Sprayer and 2-Handle Design Including Water Filter Purifier - Brushed Nickel Finish 0195SN by Bryan Reynolds

I love this faucet and have connected it to my reverse osmosis system. It works great but wasn't easy to install. I bought this because I didn't want to drill another hole in my granite countertop for a new reverse osmosis system. For some reason combination faucets like this seem pretty hard to come by. Other three way faucets I've found seem to go with those giant farmhouse sinks. Maybe it's because reverse osmosis systems are more common in rural areas where people drink from well water? Anyway, I've paired this with an Apec Ultimate reverse osmosis system. I have most of the instructions followed, but I have some notes on things that were missing or unclear, or what I did differently in case someone else wants to do the same. I hope I can save someone more pain and their time working under the sink. I'm not a plumber, I'm just a homeowner who finally installed this faucet. I had to remove the original countertop faucet and, to my surprise, needed a special tool called a "sink wrench" to unscrew the nut on the old faucet's stem. None of the tools I had would fit in the tiny space around the faucet stem to unscrew the nut. I went to the hardware store and got one. I now have a $15 tool that I will probably only use once. The instructions that came with this faucet do not match the parts in the box. In particular, a large black plastic ring was missing. It was not clear how the brass ring provided with the kit was to be used and there were no instructions for that part. Hopefully they will update the instructions for this in the future. I put a rubber washer on the shaft and touched the *bottom* side of the countertop (there was no point putting it on the top). I then tightened a thin metal ring and then a threaded brass ring with screw holes. Once everything was in place, I tightened the screws in the brass ring. Note that the ring that threads onto the shank is fairly soft brass so be very careful to ensure the screws are seated properly or you will easily pull the threads off. When I first installed the faucet on the countertop, my wife noticed that the entire faucet (handles and all) was spinning on the countertop. It will rotate freely in any direction and it will not work. So I went back and tightened the screws a little more, but that didn't help. No matter how tight those screws were, the faucet turned. I ended up reinstalling the ring and bolts so many times that I had to replace the bolts (M6 metric bolts, btw. If you also need to buy bolts, use the smallest head you can find. I used black hex bolts ). and the head barely had enough room to fit into the stem) After some troubleshooting we found that the stem (threaded brass pipe) that connects to the faucet was loose and that was why the faucet was moving turned. So little tip: Before installing the faucet, check the stem on the faucet and tighten it very well if it is loose. This saves you a lot of time and frustration. I'll probably use Loctite to connect the rod to the sink if it spins again in the future. Wall. The Apec reverse osmosis system I purchased comes with a complicated three-piece setup, but when every connection is another opportunity for a leak, I wanted to reduce this mess to one piece. I connected the reverse osmosis system to the 1/4 side and the cold water line on this faucet to the other 3/8 side. I used teflon tape on the 3/8 joints. Also note that since there is no on/off valve on the tee I have to close the tank valve while I change the filter or the water will go everywhere. Keep this in mind when using a tee. I also replaced the plastic fitting that connects the filtered water line at the faucet to the 1/4 reverse osmosis hose. I bought a metal version of this from Lowes that had a 1/4 tube compression fitting. I think they called it "gear". The tiny faucet that came with the reverse osmosis system had a plastic hose attached that was designed to connect to the reverse osmosis system. I cut this plastic hose off an Apec faucet and instead used it to connect a reverse osmosis system to this faucet. Before purchasing this faucet I read all of these reviews and wondered why people don't just replace that filtered water supply line. with one connected directly to the reverse osmosis system. Everyone seemed to buy a faucet that plugs into a faucet supply line and then hooks up a reverse osmosis system to the faucet. Now that I've gone through the installation, it's clear why everyone should go this route. While a single feed line from the reverse osmosis system to the faucet would have made this connection very easy, such a line does not appear to exist. The faucet-side connection on the supply line appears to be proprietary (or at least Lowes doesn't have a suitable supply line that appears to be a 1/4" male thread?). Also, the line coming from the reverse osmosis system was a 1 /4" plastic hose, and there was probably no water supply line going into the 1/4" plastic hose on the water side. a hardware store to complete this installation: one to get a faucet wrench to turn off the old faucet remove, one to get replacement screws for the brass ring (because I ended up rounding off the original screws to solve the spinning faucet problem), and another trip to get a brass fitting like the one that replaced the plastic fitting that came with this faucet So, bottom line: you probably have everything you need, but plan on a trip to the hardware store if You don't like plastic fittings. , or you are facing something unusual. Before installation, make sure the threaded rod is screwed tightly into the fitting. Be careful when threading these screws into the brass ring or you will most likely strip the threads on the ring. Consider teflon tape on water fittings, especially brass and chrome or brass and steel fittings (this fixed the leak I had). Much luck!
