Sink or tub faucet selection advice:

This article discusses kitchen or bathroom faucet types, finishes, features, and valve controls, including the advantages or properties of faucet valve types: faucets using compression valves, ball valves, sleeve cartridges, ceramic disc cartridges.

We include advice on choosing and installing kitchen countertops, cabinets, and kitchen or bathroom flooring, sinks, and other plumbing fixtures and fixture controls such as faucets. A list of kitchen and bath product manufactures and sources is included.

Design Guide to Choosing Kitchen & Bathroom Faucets

The faucet shown in our photo (left) is installed in a hotel in Molde, Norway and includes built-in anti-scald control. For added safety against getting burned by hot water in kitchens and baths, see Scald Protection for Bathrooms, Tubs, Showers.

As noted in Chapter 6 of Best Practices Guide to Residential Construction (Steve Bliss, J Wiley & Sons) :

Manufacturers offer a vast array of faucet styles and finishes. Most homeowners choose single-level models for the convenience of one-handed control, and chrome remains the most popular finish because of its durability and easy cleaning.

New finishing technologies permit nearly any color or metallic finish with similar durability.

Most faucets also have improved valve systems that make leaky faucets a thing of the past.

Finish Choices for Faucets

Most faucet finishes are guaranteed for life. Chrome, the most popular choice, is easy to clean and very resistant to scratching. For a colored finish, the best choice is an epoxy coating.

These come in a wide range of colors and are also very durable and easy to maintain, but they can be scratched with an abrasive scouring pad. Also solvents, such as nail polish remover (acetone), can soften the epoxy coating.

Many higher-end faucets now use a new high-tech plating technology called physical-vapor deposition or PVD, which can imitate almost any metallic finish from brass to pewter to gold. PVD finishes are as hard as chrome and easy to maintain, although they can be stained by drain cleansers containing lye.

Also, abrasive pads, such as steel wool or ScotchBrite®, can scratch these or any finish with enough effort. Where scratching is a concern, a brushed or satin finish is preferable, since it will help conceal scratches.

Solid brass faucets usually come with a lacquer or similar coating to protect against tarnishing. The metal will tarnish, however, when the coating eventually wears off or where it gets scratched. As an alternative, many manufacturers now offer “tarnish-free brass” finishes using PVD technology. Marketed under a variety of names, these finishes are actually applied over a chrome-plated faucet and have the durability of chrome.

A Guide to Kitchen & Bath Faucet Styles

Most homeowners find single-handle faucets more convenient, and experts consider them safer for kids than separate hot and cold levers, which are more likely to cause a scalding injury.

The copper sink and faucet shown at left is installed outdoors at El Charco del Ingenio in San Miguel de Allende, Mexico.

While the sink is attractive and easily accessed, the practice of extending an outdoor hose bib horizontally some distance out from the wall to provide a faucet over the sink is asking for leaks in the copper piping. To operate this faucet without bending the copper pipe requires some delicacy.

Faucet handle tip:

Whatever kitchen or bath faucet5 style is chosen, keep in mind that for faucet handles, levers are easier to manipulate than knobs, particularly for anyone with restricted mobility.

Lavatory (sink) faucet height tip:

Lavatory faucets should be low enough that they do not hit people in the head if they lean down to wash their face. An offset faucet or one that swings out of the way can provide greater useful space.

The faucet spout in a kitchen should be high enough to accommodate large pots and long enough to reach all the basins in a multi basin model.

One that swings out of the way can increase the useful space. High-arch or gooseneck designs are often a good solution (see Figure 6-48).

Pullout spray spouts are also very convenient, but avoid those with flimsy plastic hoses.

Look for a durable double interlock hose that will not kink.

Guide to Bathroom or Kitchen Faucet Materials

Underneath the finish, the base material for most faucet bodies is brass, zinc, steel, or cheap alloys called “pot metal.” Some economy models use plastic.

The highest-quality faucets use solid forged or machined brass, which will last the longest and require the least care, particularly in areas with hard water.

Cast brass is also used, but it is not quite as durable. Midrange faucets use brass or chrome plating on zinc alloys, which provides good durability, but must be replaced when the plating wears through. Plastic, steel, and pot-metal bodies are usually the least durable.

Valve Types Used in Bathroom or Kitchen Faucets

The faucet valve is the mechanism that regulates the flow of water when you turn the lever or knob. There are four basic types, each with pros and cons.

• Compression valves are the old standby used in traditional two-handle faucets. These have a rubber washer on the bottom of a threaded stem, which opens and closes as the knob is twisted.
  
  The washers wear out over time, more quickly with hard water or over tightening. New washers cost less than a dollar and are generally easy to replace. The metal valve seats also get worn over time and need to be ground with fine sandpaper to prevent leaks.
• Sleeve-cartridges have a hollow stem that rotates inside a metal or plastic sleeve to control the water flow in both one- and two-handle faucets. Usually the whole cartridge is replaced when it leaks, although replacing the O-ring at the top or bottom of the cartridge may work.
  
  Most cartridges are easy to replace, but some faucets require a special tool to pry out the cartridge. Choose brass cartridges, rather than plastic, if available. Replacements cost $15 to $20.
• Ball valves. Developed originally by Delta, these are still widely used in single-lever faucets. They use a hollow brass or plastic ball with spring-loaded seals to control water flow. Ball valves last a long time, and replacement parts are inexpensive (under $10), but the small parts can be tricky to assemble. Brass replacement parts will outlast plastic.
• Ceramic-disk cartridges. Considered the most reliable approach, this new type of valve uses hard ceramic disks that rotate in a cartridge until the holes line up to release water. The polished disks are nearly indestructible, but eventually the grease between the disks washes out or the washers or O-rings wear out. Typically, the whole cartridge is replaced. This is a simple operation, which costs about $10 to $20 for parts.

Watch out: while most faucet manufacturers do a great job of stocking replacement and repair parts for faucets, once the faucet is installed, the cost of repair parts may approach the cost of installing an entirely new faucet assembly. We found that some brands (including Kohler™) can list stunning prices for small replacement parts for faucets, cartridges, and handles - DF.

Question:

(June 26, 2015) Kathy said:
We are looking for a new kitchen faucet. All the ones I like have 1.5 gpm, maybe 1.8 gpm. We are used to very high water flow/pressure throughout the house. I can't stand a faucet with low pressure. Looking at Moen Camerist, Braemore or Wetherly in a darker bronze color. They all have a long enough spout reach and good height, but not too tall. I cannot tell how much plastic in each one, whether it is high quality and will last and if there is a way to increase the water flow/pressure in any of them? Can the cartridge be changed? Aerator? Something else to take out?
Also, If I got one with a side spray, would the spray be soft and not very strong? Also want good warranty, customer service and easy to get parts should anything happen. Any advice on any of these faucets or any others I should be looking at? Thanks!

Reply:

Whew. A thorough product review of dozens of choices is in order. Take a look at the specifications on the box or the spec sheets at the faucet manufacturer's website; you'll see the parts explosion, cartridge replacement parts, and also the rated flow in gpm. While I cannot recommend removing it, some kitchen faucets restrict flow by a removable disk found at the base of the faucet spout. If that disk is removed the flow rate will increase as will the flow rate (for the same supply pressure) if you simplify the aerator at the faucet spout tip.
