Rated 1 out of 5 by from What a lemon! This is the worst faucet ever! Do not buy it! While it is super easy to install, it didn't hold up under regular use. In less than 6 months it started dripping. I thought it was because my children were not turning it off all the way after using it. Boy was I wrong (sorry kids for fussing at you!). Even after replacing the handle cartridge with a brand new one (which cost almost half a much as the faucet itself!), it still dripped. Not to mention when I went to change the cartridge and turn the water off under the sink, under the sink was damp. Upon further inspection, there were drops of water running down the tubing from inside the faucet under the sink. What a waste of $70!

Rated 5 out of 5 by from easy installation, works great When our kitchen faucet broke, we went to Lowes for a replacement. Since we'll be swapping out our counter and sink in the next 2-3 years, we looked for the "cheap stuff". Our eyes came to Delta 400-DST-L for $79. We only needs to last a few years. Upon installation, I was pleasantly surprised. The water lines were configured to hook to the 3/8" shut off valve. Awesome! One less point of failure and less accessories to buy. Thank you Delta. After removing the old Moen faucet that was rusted on and took quite a bit of effort and time to remove, I appreciated the plastic threads and nuts on the Delta faucet. Won't have to work about rust there. Installation was a breeze and no special tools were required! Water flow is so much better than the replaced Moen faucet, so kudos there too. So far, I am very satisfied and happy. If it lasts the 2-3 years, I'll be very happy, but I'm thinking next time I need a faucet (whether kitchen or bath), I'm heading right to the Delta faucets. It looks to me like they did their research and offered an easy, homeowner product. Thank you!

Rated 4 out of 5 by from This product has no mounting parts underneath the sink that would rust which makes it great when the product has to be changed years down the road. The installation was easy and the water connections were extra long so no extra supply hoses were required. Only one thing: wished the end of spout would be higher in the air. It's a little difficult to get standard jugs under for filling, etc.

Rated 5 out of 5 by from Super product Bought this to replace another Delta faucet that another brand of fixit rings & gaskets didn’t work well. Had it for about 10 years & told my wife let’s go get a new one. This one was the choice & with the sprayer too I am glad we got it. Make sure per instructions to silicon seal it to the sink just to prevent leaking. Buy it & you’ Be glad you did.

Rated 1 out of 5 by from Plastic supply lines on a "quality" Delta faucet? I first learned about Delta faucets when I was a teenager sweeping the floors of a wholesale plumbing supply company in the 1970s. "One of the best" said the Delta rep, and it was often repeated by our salesmen. I have purchased and recommended Delta faucets for the past 40 years. Recently, I purchased a Delta bathroom faucet, got it home, opened the box, and found permanently attached PLASTIC supply lines - plastic that becomes brittle over time and breaks (as did my plastic supply lines, 10 years ago, that I had attached to my Delta faucet with permanently attached COPPER supply lines. That WAS a mess. That was my fault and I replaced ALL my supply lines in the house with braided lines). Needless to say, I returned my new Delta bathroom faucet, looked for a Delta with copper lines with no success, and had to purchase an American Standard brand which has permanently attached COPPER supply lines. Now for the Delta kitchen faucet, relevant to this review, I had installed 3 years ago. I had a contractor redo the counter top and install new sink, disposal, faucet and all pipes. I INSISTED on the Delta brand faucet, but never looked under the sink until my experience with the Delta bathroom faucet above. What did I find? Yes, permanent PLASTIC supply lines. Please advise. A loyal customer for 40 years.

How long are the supply lines from sink top to end?

Asked by: Hazfran
I just recently replaced my kitchen faucet. I reinstalled another Delta faucet. The supply lines on the new faucet were about 2 ft or more in length. More than enough to reach the cut-off valves at the bottom of my kitchen sink cabinet.

Connecting an appliance

Can I attach a small single hose inlet portable clothes washer to this faucet?
Asked by: Wxyz
Hello K, Thank you for your question. A hose can be attached to the faucet, but an appropriately sized adapter will need to be used. Best Regards, Courtney

how to stop a drip on delta 400-ss-dst-l

can we eliminate the mounting plate and add a escutcheon ring to mount the faucet to a undermount corian sink /

we have a new (1yr old) 400-DST-L Delta faucet that we like to reuse with our new undermount corian counter top? Does delta make a Escutcheon ring that we can remove the chrome mounting plate and use the existing faucet with a single hole instead of three holes ? Please advise, Thank you, Tony Merlino
Asked by: Tony
Hello Tony, Thanks for your question! Unfortunately, the escutcheon on the 400-DST-L cannot be removed. If you are looking for the faucet to install with the faucet going through one hole and the side sprayer going through another with a similar style to this unit, then any of the following faucets would work: I hope this helps! Best Regards, Justin

Disconnecting Sprayer Line

I need to disconnect the sprayer line from the faucet to move it. I loosen the clip, but the sprayer coupling won't release the sprayer line. Is it supposed to be removable or is it a permanent coupling once installed?
Asked by: Renmax
Hi Renmax, Thank you for your question! As long as the diverter clip is completely out of the way you should be able to pull down on the sprayer hose to disconnect it from the diverter tube of the faucet. Best regards, Brandis
