BAROSSA® Pull Down Kitchen Faucet - High Arc Stainless Steel Sprayer with 360° Swivel for Modern Home & Commercial Use | Perfect for Washing Dishes, Filling Pots & Cleaning Sinks

I chose this faucet for a customer's kitchen for two reasons: Because of the good reviews; and the Kohler name.Their design is really good, along with very simple installation design. They make it easy to install. Better than many of the competing brands. However, there is one fatal flaw in this faucet, and perhaps others on the market. There are water flow-restrictors inside the main hose. After I installed it according to all the instructions, I turned on the faucet only to see nothing better than a good trickle of water. I asked the customer if they have low water pressure? They answered NO, our pressure is great! I double checked all hoses, rechecked the fittings to see they weren't over tight. No change.Next, I called customer service and after trouble-shooting over the phone for 10 minutes, the woman said she too was stumped, and offered to send a replacement. I said; no thanks, since that would take 7 days to arrive, and I could return it to Home Depot in 15 minutes. But I hadn't given up yet.I looked over all the hoses and connections for a solution. It got narrowed down to one connection. The faucet wand connector hose has a white quick-release clip on it. I disconnected it from under the sink and then unscrewed it from it's hose connection. The white plastic piece had parts inside, so I unscrewed this part and used a small screwdriver to get out the first two pieces. They were blue one-way flow valve parts, and I wondered if they could be the issue. But there was still one more small piece inside the white plastic housing. I tried to blow air through this housing and could barely get enough air through it to amount to a small fa*t. It was pathetic. Using a chopstick, I pushed it out of the tube. Then I replaced the other two blue one-way flow valve parts, and reassembled it all. Voila. The faucet now works perfectly, like it should have out of the box.There were no visible signs of anything blocking this little part I removed. Nothing at all. This was simply in place to restrict the water flow. Perhaps according to some Federal standard for water conservation. But this was extreme, and if not remedied, would have meant a product return along with a really negative review. As it stands, I give Kohler a huge thumbs up for making the part in a fashion that allowed the buyer to unscrew it and remove the restrictor. The flow now is what most would consider normal. It is not Huge flow, just normal flow. We will never see Huge flow with the design of the faucets today. But you must remove this part in order to gain normal flow.I've attached a photo to show you this part I removed.I hope this helps you all in your decision to purchase a new faucet.
