It's great for those who want to add a splash of color to their kitchen. It's easy to install and easy to clean.

It costs a bit more than your standard kitchen faucet for hard water, but it seems well worth the price for all it offers.

Kohler K-99260 Features:

  • DockNetik – a magnetic docking system within the faucet body offers secure locking for the spray-head in place when not in use, which means the spray head won't droop. The pull-down function glides smoothly.

7. Delta Essa Single-Handle Bar-Prep

The Delta Essa uses a contemporary take on euro designs and comes with many of the features you would expect from Delta.

It's a mid-range priced quality kitchen faucet that offers the basic features of a pull-down faucet.

8. Kraus KPF-1602 Single Handle

Kraus KPF-1602 Single Handle Pull Down Kitchen Faucet

The Kraus KPF-1602 faucet is constructed of lead-free brass and has a rust-resistant finish. It's a bit different from most faucets in that it has an open coil spout and is listed as a commercial styled faucet. The faucet comes in a choice of chrome or stainless steel finish. The spray face uses a Neoperl aerator, a Kerox ceramic cartridge, and a two-way diverter for drip-free flow control. One of the functions we like is its pre-rinse spray, which is quite powerful.

Kraus KPF-1602 features

  • Commercial Design – the open-coiled spout and high arch gives a more modern industrial aesthetic.
  • Flexible – the pull-down sprayer and comfort height spout makes this faucet very functional and flexible. The single lever handle gives easy flow and temperature control.
  • Integrated Diverter – allows you to switch from a powerful pre-spray to spout instantly.
  • Kerox Ceramic Cartridge – one of the best in the industry, these cartridges have been tested over 500,000 cycles and give drip free usage.
  • Neoperl Aerator – reduces water waste without having to sacrifice on water pressure.
  • Pre-Rinse Spray – this function allows you to divert your water flow from the main spout with the press of a lever on the sprayer.
  • Open-Coil Spout – the spout can swivel 360 degrees allowing you to reach all areas of the sink.
  • Easy Installation – with its single hole mounting, you can effortlessly integrate the faucet into your sink. All of the mounting hardware needed is included.

Pros

Easy installation

Ceramic cartridge

Pre-rinse spray function

Easy to clean and maintain

Heavy duty components

Cons

Some don't like the diverter function because they can't use the main faucet and sprayer at the same time.

Main valve is directly under the main spout making it hard to not get yourself wet when turning it on.

Final Verdict

This faucet has a very dramatic look to it and is pretty heavy duty. So, if you want something contemporary with an industrial aesthetic, this faucet is for you. It does seem that a ¼ turn screw has been removed as a feature to this model, where older versions had it. While it says it saves water with its aerated spout, many feel that it wastes more water and is harder to use based on its design. This may be more a problem of preference for the buyer, but something to take note of.

9. Delta 978 DST Leland Single Handle

Delta 978 DST Leland

The Delta Leland faucet has a more traditional look, giving it a timeless appeal. It comes with a soap dispenser and has two finishes to choose from; Brilliance Stainless and Chrome. It uses MagnaTite technology for easy docking and undocking and falls in the lower to mid-range pricing.

Delta Leland features:

  • MagnaTite technology means your spray head won't droop over time and it makes it easy to dock and undock smoothly.
  • Diamond Seal technology has a tough diamond coating for the valve for long lasting durability.

  • Duramount mounting system and one piece supply line eliminated leaks.
  • Touch-Clean soft, rubber nubbins are equipped with the nozzle for easy cleaning and the prevention of mineral buildup.
  • You have both a spray and stream option.

  • Can be installed for a 2 or 3 holed sink

Pros

Supply lines are included

Fairly easy to install

Easy to clean

Good quality for the price

Cons

Soap dispenser sits lower than expected, giving little clearance between the pump and your hand, and making it difficult to fill

Cold and hot lines could be more flexible to make installation easier.

Final Verdict

This faucet has the usual Delta quality and a traditional appeal to it. While the soap dish inclusion is a great idea and is still functional, it seems to have some issues being awkward to fill because it screws from underneath. If you can get past that issue, this seems to be a pretty good kitchen faucet for hard water with its features.

10. Delta Cassidy Single-Handle 4197

Delta Cassidy Single-Handle 4197

The Delta Cassidy has that old time appeal that is a great addition to rustically styled kitchens. The shape is designed after the silhouette of a woman and comes in a Venetian Bronze finish. It only has a 120-degree swivel range, however, which may be an issue for some. It uses Delta's Diamond Seal and MagnaTite technology, the Duramount mounting system, and Touch Clean sprayer.

Delta Cassidy features:

  • MagnaTite technology means your spray head won't droop over time and it makes it easy to dock and undock smoothly.
  • Diamond Seal technology has a tough diamond coating for the valve for long lasting durability.
  • Duramount mounting system and one piece supply line eliminated leaks.
  • Touch-Clean soft, rubber nubbins are equipped with the nozzle for easy cleaning and the prevention of mineral buildup.
  • You have both a spray and stream option.

  • Lifetime Limited Warranty

Pros

ADA compliant

20 inch reach on hose

Reasonably priced

Unique design

Cons

Tough to install

120-degree swivel as opposed to 360-degree swivel on many other faucets

Many have found the hose to be troublesome when pulling with it lagging to push and pull in and out of the hole

Final Verdict

While the Delta Cassidy has a unique design and many of the features you would want in a pull-down faucet, there seem to be some issues with flexibility and smooth application. The sprayer part of the faucet is made of a chrome plated plastic material, which may not withstand the wear and tear as well. The hose isn't reinforced and can kink and pulling out and pushing the sprayer back is not very smooth, with no automatic retraction. While it's not a bad faucet, these are things that may put buyers off.

What Are The Advantages Of Using A Kitchen Faucet For Hard Water?

A kitchen faucet that is made specifically for hard water has special elements, such as a filter and a ceramic sealed surface that makes them pretty much invincible to the effects of hard water and the damage it can cause.

Staining, Residue, and Buildup

For a start, you will be eliminating the issues caused by hard water, such as stains and buildup. Minerals left behind can build up over time, leaving your sink and faucet stained with white, green, red, brown, and blue stains, as well as leaving a slimy or filmy residue. These stains can be extremely hard to remove, sometimes needing professional products to cut through and remover any scaly buildup. A buildup of residue can also lead to your faucet becoming blocked, which minimizes the amount of water that can come out of the faucet. Installing a kitchen faucet for hard water will eliminate these issues.

Hard Water Damage

It's not just your faucet that can become discolored or damaged. Hard water deposits can also damage any rubber washers used to seal your faucet against leaks, which can lead to even more damage. If you use water from your kitchen sink to fill appliances, such as your tea or coffee pot, these can become damaged with buildup and limescale deposits as well. This not only leads to leaking but can make your hot beverages taste awful. The same goes for crock pots, irons, steamers, and cooker that you fill from your kitchen faucet.

What to Look for in a Kitchen Faucet for Hard Water

We've shown you the top 10 kitchen faucets for hard water on the market. However, it's important to know what to look for when purchasing a new faucet. Here's our buying guide to help you.

Filter – this is the most important aspect to consider when buying your faucet. Your faucet should have a high-quality filter that is made to remove minerals from the water.: Faucets with single piece filters are best because filters that have several pieces can easily become damaged from mineral deposits over a period of time. They are also harder to clean than a single piece filter.

Faucet Design – something to keep in mind, like with filters, is that a faucet that has a more complicated design has more of a chance of accumulating mineral build up over a period of time. A simple, straightforward design is the best way to go.

Materials – it's important to know what your faucet is made of because some metals are more easily damaged than others. Polished chrome and brushed nickel are the most recommended materials for your faucet.

Sealing – a faucet that has a sealing coat tends to last longer and be more effective over time. Ceramic coating is usually the best option and these are designed specifically to withstand the damage caused by hard water.

Price - price is also an important factor when buying a faucet. Top of the line faucets will cost a lot more. However, there are a number of good quality faucets that will do the job and not break the bank. More expensive doesn't always mean better, so make sure you verify the quality of the faucet before you buy it.

We hope the research we have presented, along with the buying guidelines will help you choose the best kitchen faucet for hard water sinks in your home.
