Question: Do you have to use the included water dispenser our can I keep my faucet sprayer and connect the filter to the faucet cold water line only?
Document: Let me first start by saying I really do like this unit. It comes with everything you need to swap out a soap dispenser or sprayer on your sink and replace it with the included faucet to have fresh water at your finger tips. The only issue I had was with the installation parts.Specifically, the plastic adapter that taps you into the cold water and runs the tubing from the filter and also from the faucet.
This water filtering system includes a faucet that has to be installed separately, the filter, tubing and an indicator that shows how long the filter has been in place. This connects to your cold water line. Instructions are included but they do not show all the parts or do a good job at explaining how to install the system. The hardest part was a plastic T piece that proved difficult and it kept leaking. Upon further investigation, I located a small plastic nut that attaches to the plastic T and prevents leaking.
I break out in a cold sweat at the words "compression nut" so at least I didn't have that to deal with. The tube connections are "push in" and the filter is "quick connect". The aggravating part is the little  plastic thing I call a "T" connection. Maybe it has a more technical name. It goes into the cold water line. I wonder how much of a bump it would take to cause a leak. I didn't test it.
I was hoping that the unit would be compatible with the cold water line (created a bypass so that cold water would have to travel through the filter - therefore hot water would not and so washing dishes and such wouldn't use much filtered water). But the additional spigot setup is ideal.Here are the problems:  This unit is kind of pricey. And it is a bit of a pain to install. Anything you are installing that affects water lines is a pain.
He said with other systems he's installed he's had to run out to get one or more parts that weren't included . I told him I'd write the letter!!! I live in a rural area and have a lot of sediment in my water. I have an under-house sediment filter, but stuff was still getting through to the tap. I LOVE the separate faucet that came with this system...it was a quick install where the old sprayer used to be.
But that means changing the filter more often (i.e. more work and more cost), because you end up filtering cold water that you use for cleaning instead of drinking.Thus, the ideal water filtration for me seemed to be an under-sink filter with a dedicated drinking water faucet.
We recently moved to a county where the water is not too tasty. In the summer under drought conditions the water hast a dirt taste too it as the reservoir gets lower. I found the filtrete 4us-Maxl system a great replace ment for the easily breakable and inconvenient Brita Jugs and environmentally unfriendly bottled water.We aren't plumbers but were able to follow the directions enclosed. they are simple and straight forward for most sink systems. It was easy to connect the filter to the water line under the sink.
I hired my usual handyman to install this product. I have the correct sink design to use this product - you *must* have a hole next to the faucet where a handheld sprayer or other device would normally be found, otherwise it involves too much expensive work to have a hole cut into your stainless steel sink.The handyman realized there would be an additional $40-50 that would need to be spent at Home Depot buying extra parts in order for this filter to fit and work right underneath my sink.
I like having an installed filter for drinking water. My refigerator has one, but I don't always use the water from there (such as for jello or drink mixes.) We already had many of the parts for ours (unlike some reviews) because the previous owner of our house had a filter in that "sprayer" spot.
The hole for the sprayer was much bigger than the filter assembly so you just have to center it by eyeball and tighten it the best you can. Be sure you have the little white do-nut shaped thing in the "T' connector. It isn't mentioned but I think it is supposed to be a washer. I never did figure out what the white adapter-quick-connect thingy was so I guess I didn't need it. You might want to replace the mounting screws with shorter pan-head screws.
Answer: You can with adapters, but the water lines that come with this filter are really small, so you won't get much volume or pressure.
