This Company In Brief

Masco's Delta fau­cet was organized in 1954 to market faucets designed around the Delta Ball valve invented by Landis Perry in 1952.
At first, the company made only kitchen faucets. Bath faucets were added in 1960. By 1958, just four years after the product was launched, Delta's sales topped $1 million for the first time.
Delta is still one of the best selling faucets in North America, and one of the faucets most preferred by plumbers. It has been our pick for best value American-made mid-priced faucet since 2010.

If there is an 800 lb. gorilla in North America's world of kitchens and baths, it is Masco Corporation — one of the world's largest faucet manufacturers. Note 1 In addition to Delta fau­cet, it owns in Germany, and Bristan Group, Ltd. in the U.K.

Masco's Faucets

are really the low, middle and high ends of the same Masco fau­cet line.

fau­cets are made by another Masco company, Brasstech, Inc. and are at the middle/high end of American faucets. Brasstech also makes fau­cets for the upscale retailer.

owned by Masco Canada, is a manufacturer of budget fau­cets for the Canadian market.

the upscale fau­cet manufacturer in Germany, is the last player in Masco's rollcall of famous fau­cets, also at the high end of the Masco lineup.

In addition, Masco owns Bristan Group, Ltd. in the UK, but none of these faucets are sold in North America.

Masco is also a major player in cabinets (Kraftmaid, Merillat, Mills Pride, Quality Cabinets, Moores Furniture (UK)), paints and coatings (Behr, Kilz, Hammerite), bathtubs and showers (Aqua Glass, Hüppe, Mirolin, Watkins Spas), water, gas and steam fittings and connectors (Brasstech, BrassCraft, Master Plumber and Plumbshop ), replacement windows (Milgard, Masco UK Window), decorative hardware (Liberty Hardware, Franklin Brass), and even staplers (Arrow).

Founded in 1929 as Masco Screw Products Company by Alex Manoogian, an Armenian from Smyrna, Turkey, who fled to the U.S. at age 18 from the Armenian Genocide (1915-1918). The company was renamed Masco Corporation in 1961.

The company history states that Alex Manoogian invented the company's signature ball valve. He didn't. It was invented by Landis H. Perry, a professional inventor, who started tinkering with the design after his discharge from the military in 1945. In 1952 he patented it and started shopping for a company to make it.

Manoogian realized its possibilities, and after refining the design to eliminate some defects and make it more easily manufactured, founded Delta fau­cet in 1954, initially as a separate company, later as a division of Masco, to make single handle faucets using the hugely successful new valve.

Delta's Diamond Seal Technology® Cartridge

Delta's new Diamond Seal Technology® cartridge features a coating of diamond powder on the rotating disk to continuously polish the fixed disk and scrub away any minerals that may insinuate themselves between the disks.

Delta tested this new technology to 5 million on/off cycles without a failure — ten times the current standard for cartridge durability and equivalent to about 700 years of normal use in a kitchen or bath.

At first, the company made only kitchen faucets. Bath faucets were added in 1960. By 1958, just four years after the product was launched, Delta's sales topped $1 million for the first time. Delta is still one of the best selling fau­cets Note 2 in North America, and one of the fau­cets most preferred by plumbers.

Masco is an American faucet manufacturer that has resisted exporting all of its manufacturing to China. Delta makes faucets in Greensburg, Indiana and Jackson, Tennessee. It owns two more plants in Ontario: one in London and another in Cambridge that serve the Canadian market.

Delta claims that over 4,500 of its products (not just faucets) comply with the Buy American Act (BAA), including its new Diamond Seal Technology ceramic disk cartridges (see below). Delta employs over 1,300 Americans in the U.S. and nearly the same number of Canadians in its various subsidiaries in that country.

Not all Delta fau­cets are made in North America, however. Delta closed one of its factories, in Chickasha, Oklahoma, laying off 600 American workers, soon after its new plant in Panyu, China became operational in 2001. The China plant makes Delta products for the growing Asian market but also provides faucet parts to Delta's U.S. and Canadian factories

Delta also contracts faucet manufacturing to other companies. Customs records show that Delta imports faucets, fully assembled, in the box, and ready to sell from,

So, you cannot assume that a particular Delta fau­cet was made in the U.S. In fact, there are indications from plumbers that the same model faucet may be made in more than one factory, some in the U.S., some not. So always check the "Made in…" label if you are looking to buy a faucet made in the U.S.

Alex Manoogian (1901-1996)

"Do not be satisfied with average performance. Strive for excellence. If you cannot give your customers a better value and a better product, do not sell the product."

Some of Delta's ceramic cartridges are from Fluehs Drehtechnik in Germany, a manufacturer of some of the world's best ceramic cartridges. These are being phased out, however, in favor of the new proprietary DST cartridge that is giving the Germans a run for "best-in-show" honors (see more, below).

Among plumbers, the Delta line of faucets is a perennial favorite. In every plumber poll, we have ever read, Delta is almost always the first or second choice as the go-to faucet.

Plumbers like faucets that don't cause trouble — which pretty well describes Delta fau­cets to a "T". And, if it does break, Delta gets the plumbers' vote as the easiest faucet to fix, even easier than Moen.

Delta also ranks well in our homeowner "top of mind" survey. Consistently between 25-28% of the readers taking the survey identify delta as the first brand to come to mind when they think "faucet".

Delta was one of the early faucet innovators. The pioneering Delta ball washerless cartridge has been widely copied and sometimes outright counterfeited. It is on its way to a justly-earned retirement after a 60-year career.

Its replacement is a proprietary ceramic disk cartridge invented by Delta. The company claims that this Diamond Seal Technology cartridge is a quantum leap in cartridge design. We think it a major improvement — "quantum leap", however, remains to be seen. Check back in 20 or 30 years. We'll have more information then.

WaterSense Sustained Excellence


Delta Faucet Company has been repeatedly recognized by the U.S. Environmental Protection Agency (EPA) as a WaterSense® Sustained Excellence Award winner.

The award is the EPA's highest recognition for continued, exemplary efforts to help advance the WaterSense program and water efficiency.

Since 2012, all new Delta Faucet lavatory faucets have been designed to meet or exceed WaterSense standards set by the EPA.

Since the program's inception in 2006, the WaterSense program has helped consumers save a cumulative 2.7 trillion gallons of water and more than $63.8 billion in water and energy bills.

More than 1,900 utilities, manufacturers, retailers, builders, and other organizations partner with the EPA through its WaterSense program.

One disk in the two-disk set is coated with diamond dust, a feature that Delta says helps keeps the disks absolutely smooth since the coated disk continuously scrubs and polishes the other disk so they always mesh perfectly. It also continuously grinds away any mineral deposits that may insinuate themselves between the disks. The more you use it, the smoother it gets.

Delta has had this cartridge tested through 5 million cycles — about 10 times the lifespan of a typical ceramic cartridge and equivalent to about 700 years of daily use in your kitchen. Note 3 But, if it does break and you ever need to change the cartridge, it's very easy to do, and the new cartridge is free to the original owner of the faucet for as long as he or she owns the faucet.

The DST technology is already available in many better Delta and Brizo faucets, and will eventually be the only cartridge used in Delta sink faucets. DST-equipped faucets are easily identified by the "DST" at the end of the faucet's model number.

Delta's second major innovation in fau­cet technology is its patented process of moving water through a faucet without any contact with metal.

The company uses a cross-linked polyethylene tube threaded through the faucet all the way to the tip of the spout through which water is channeled. Because water never touches a brass component in the faucet, it cannot pick up any lead or other harmful material from the faucet's brass body or spout.

Cross-linked polyethylene, or PEX, is so strong that it is now the preferred material for residential supply piping, replacing copper in most installations. (For more detail on the materials used in manufacturing faucets, see Faucet Basics: What Are Faucets Made Of?.)

Most Delta fau­cets are available with the company's patented Brilliance® finishes developed by Vapor Technologies Inc., another Masco company that was one of the early pioneers of PVD technologies. Twelve PVD finishes are available, three of them All Delta finishes are guaranteed never to corrode, tarnish or discolor for as long as you own your Delta fau­cet.

Delta's newest innovation is its electronic hands-free faucet which it calls Touch2O® technology. Delta is ahead of most faucet companies for its electronic technology, but we are somewhat skeptical of electronic technology of all kinds in a faucet. What the hands-free feature does at this point is nothing more than turn the water on and off. So it's not really a hands-free operation. Flow rate and water temperature still have to be adjusted manually.

Additionally, electronic technology is not very robust. We have little confidence in its long-term durability, and neither does Delta. While The Delta warranty on all of the other parts of its faucets is for the lifetime of the buyer, the warranty on the electronic parts of the Touch2O technology is just 5 years, which is much longer than the 1-year warranty offered by many other faucet companies on their electronics, but still considerably shorter than a lifetime warranty.

In our experience, once the novelty of hands-free operation has worn off, the feature is rarely used because it simply is not that much more convenient than manual operation, and when the technology fails, many of our customers don't bother to have it fixed. For more reliable "hands-free" operation, opt for a wrist-blade handle of the type used in hospitals which can be operated with an elbow if your hands are too really too dirty to touch your faucet.

Delta fau­cets have historically been long on solid engineering and precise manufacturing but more than a little short on style. But, things they are a-changin'.

Delta has borrowed a few designers from Brizo and Hansgrohe to lend a little pizzaz to its collection as a complement to the introduction of its new faucet technologies, and we are starting to see Delta fau­cets that, while certainly not avant-garde, are a giant step up in the style department.

The collection is still skewed toward traditional and transitional faucets — Delta's meat and potatoes market — but some crisp contemporary designs are starting to show themselves, and we expect more will come.

For a true designer faucet from Masco, However, you might have to step up to its higher-end Brizo faucet line. Same first-class warranty and customer service, same precise engineering and quality manufacturing, just more style.

Our opinion of Delta is that it is a good, solid, reliable, durable, dependable, and increasingly stylish lifetime faucet. It has been the most popular faucet in America for over 50 years for good reason. It is, overall, a very good faucet, and reasonably priced with some of the best warranty and post-sale customer service in America.

Our rating of the company's products has improved one point due to the widespread adoption by Delta of the Diamond Seal cartridge and InnoFlex waterways in its faucets. The new cartridge is proving to be something of a phenomenon, with very few reported problems since its introduction. As more faucets in the Delta lineup are converted to the new technologies, we expect the company's rating will continue to improve.

Faucets comparable to Delta include

It is almost impossible to go wrong buying a Delta fau­cet. If there is a better fau­cet made anywhere in the world, we have not found it. The finish, cartridge, and water channel technology used in Delta fau­cets is unmatched by other faucets in the same price range. In fact, cartridges equal to the DST cartridge are not available from other companies at any price. The nearest equivalent is the PVD+ cartridge coated with diamond-like-carbon used in faucets. These are, however, priced at about double the cost of a Delta fau­cet.

We are continuing to research the company. If you have experience with Delta fau­cets, good, bad or indifferent, we would like to hear about it, so please contact us or post a comment below.
