Question: I installed my faucet and can not get the sprayer to retract? Also can not figure out what this gravity ball is? The instructions don't help...Please help me!?
Document: The item was ordered twice , both order were missing installation instructions and parts list.I contacted Ligtin for help and they said I would have to call to China for customer service. Also the water line that come with the faucet do not have a standard fitting to the water pipes.
I'm a contractor and had no problems installing this but no instructions were included. Also has very powerful sprayer but needs to be shut off in order to go back to faucet mode, which I don't mind. I would definitely recommend this.
Also, if you had a seperate sprayer, I advise you to fill it with a soap dispenser or faucet hole cover. Hey, you get what you pay for. If you can afford a 500 Moen faucet, then you can afford a plumber to install it. If you're a handy and can overcome the minor details and like to save some $$, then this is for you.
Now, when I use the spray, I have a 50-50 chance that the faucet will reset from spray to solid. The only way to get the sprayer unstuck is the hit it with a dishrag. This $400 (with plumber costs) monstrosity also drips for an eternity after I shut it down because the entire neck needs to drain. If you really need something to vent your rage on, buy this piece of garbage.
well i installed this faucet my self about a month ago. it was a first time i ever installed the faucet and it took me about two hours to install and figure this out. it could be quicker but there were no clear instructions. the main problem with this faucet is that the nobe was keep getting losen and had to tight it over and over.
Love it! Was able to get it installed, but instructions would have been good. Otherwise solid and great! Handle works with just the slighest touch.
Very pretty but not very efficient. Hose does not retract very easily. Thankfully does not leak. If hose went in and out easily it would be the prefect faucet. I have to reach under my sink to pull the sprayer back into place.
The faucet is the most useful gadget in our new kitchen. Great help for my wife, obsessed with cleaning. It also allows her to reach corners of the sink. Great value, fast delivery, this is the way internet retailing should be.
I love this faucet, it was a little difficult to install because it had different ends than our other faucet had. But in all took about 30 minutes to install. I love the pull down sprayer and the handle makes it so easy to turn it on quickly. This was also delivered very fast. I wasn't expecting it before Christmas and it came Christmas Eve :)
I love the faucet. It looks great, works great and it is so convenient to use the sprayer. What I didn't love was the lack of instructions. There were none. Package included a booklet for installation of several faucets, but none that applied to this item. There was a list of parts included, but it was generic and included parts my unit didn't need. In the end I called a friend of mine who is a plumber to finalize the connections that needed to be adapted.
