Upflow Carbon Filters, for Excellent Whole House Water 

For City Water Users


Simple “in/out” upflow carbon filters offer an inexpensive way to remove chlorine or chloramine from city water. Among the simplest of water treatment devices, they require no electricity, no drain connection, no setup programming, no cartridges to change, and, for years, no upkeep.

Our version of the in/out upflow is the best product we can make, and we think it’s the best anyone can make. Our in/outs feature the best parts available for simplicity of operation, long service life, effective performance. We use the superior Vortech mineral tank and the tough, reliable Clack In/Out Head. We provide a  clear-bowl media trap to assure that no filter media enters the home’s service lines, plus a specially designed installation adapter to make startup of the filter easy. An optional bypass valve is sold separately. (more…)

Adding a 4th Stage to your 3-Stage Black and White RO Unit


Black and White filters and RO units are designed for easy modification.  If you want to add a fourth stage to your three-stage Black and White RO unit (a calcite post filter to raise pH is the most common addition), we have a kit with everything you need.

The picture shows the finished modification.


To install, just turn off the inlet water, turn off the tank valve,  open the faucet to relieve pressure, then remove the faucet tube from the white housing.  (Quick connect fittings release by pushing in to the collet and simultaneously pulling out the tube. See website for details. )

Install the inline filter on top of the membrane as shown in the picture.  You’ll want to determine which way the water flows through the filter by looking at the directional arrow.

When the inline is mounted on the membrane, use the 1/4″ tube to connect the white vertical housing to the inlet of the inline filter, then attach the faucet tube to the outlet side of the inline filter.

Turn on the water and check for leaks.  The new filter will need to be rinsed for 3 or 4 minutes.







Wild Ride Awaits for Water Issues Under Trump

by Matt Weisser

Like his vow to build a border wall, Trump’s promises around water issues will be difficult to fulfill. And the path to get there could be disruptive for water agencies and the environment.

Donald Trump made some big campaign promises about water during his election campaign. Now that he has been elected president, those promises could dramatically shake up how water is managed in the arid West.

In one of his few direct statements about water, Trump has said he wants to invest in treatment systems to prevent problems caused by aging distribution lines, citing as an example the drinking-water contamination in the Michigan city of Flint. To do this, he proposes to triple funding for a federal loan program, called the state revolving fund, from the current $2 billion to $6 billion.

This could be a boon to local water and wastewater utilities struggling to pay for decaying infrastructure.

Paradoxically, Trump has also vowed to slash Clean Water Act regulations. In particular, he is targeting rules adopted by the Obama administration to protect wetlands and marshes, the nation’s natural water filters.

Like Trump’s vow to build a wall on the Mexican border, these proposed changes would encounter a host of inconvenient realities associated with government. Working that out is certain to be disruptive, whatever the outcome. (more…)

California Is Sinking


Joseph Poland of the U.S. Geological Survey used a utility pole to document where a farmer would have been standing in 1925, 1955 and where Poland was then standing in 1977 after land in the San Joaquin Valley had sunk nearly 30 feet.

In the 1930s, scientists noticed that the land in the fertile San Joaquin Valley was sinking. The cause was a mystery. No one blamed corporate farmers who in the 1920s had begun massive pumping of groundwater to support the growth of highly profitable but very thirsty crops. (more…)

Bathing in Well Water With Arsenic

by Gene Franks


Is it safe to shower in water that is contaminated with arsenic?

Dr. Kelly A. Reynolds in a December 2016 Water Conditioning and Purificication article on arsenic got my attention in her beginning  paragraph: “Exposure to arsenic via inhalation, ingestion and skin absorption can lead to cancers of the lung, bladder and skin.” I took note because I have been advising our customers for some time that arsenic in well water is mainly a drinking water issue and that there is little or no evidence that exposure to arsenic through bathing in water that is a few parts per billion over the current recommended limit of 10 parts per billion has any serious health consequences. Consequently, when a well water  customer calls or writes with an arsenic issue, we usually recommend taking care of the drinking water, which is easy and not too expensive, and forgoing the much more costly, complicated and often unreliable whole house treatments for arsenic.


Are US Dams Safe?

Editor’s Note. The piece below is excerpted and adapted from a Circle of Blue article by Brett Walton.


If you live downstream from a dam, you hope that someone is maintaining it and monitoring its safety. This is not always the case. In Alabama, for example, all but 10% of the state’s dams are privately owned and regulatory oversight is minimal.

The universe of American dams is expansive. There are tailings dams that hold back a slurry of mine wastes, stock ponds for irrigation or watering cattle, and artificial lakes for sailing and speedboats. There are dams to detain flood waters and dams to filter debris. Then there are the hydropower behemoths such as Grand Coulee and Hoover, symbols of 20th-century engineering might. Though iconic, these canyon-bridging concrete plugs are the minority. Most dams are small structures less than 25 feet tall made of packed dirt and rock and built more than 50 years ago.

Surprisingly little is known about why individual dams fail. Few states do autopsies to learn precisely what went wrong. That is why a Stanford University professor founded the National Performance of Dams Program in 1994. The program’s goal is to learn from past failures so that managers can identify problems before they become tragedies. The program’s researchers have found that the U.S. dam industry is far behind the nuclear power and oil and gas pipeline industries in the amount of data it collects. (more…)

Hyponatremia, or Water Intoxication


Drinking too much water left a woman with a urinary tract infection seriously ill, and doctors said water intoxication can kill you. The case in point is a 59-year-old London woman who, in an attempt to “flush out her system,” drank water so copiously that she developed hyponatremia, also called water intoxication.

According to the Mayo Clinic:

Hyponatremia is a condition that occurs when the level of sodium in your blood is abnormally low. Sodium is an electrolyte, and it helps regulate the amount of water that’s in and around your cells.

In hyponatremia, one or more factors — ranging from an underlying medical condition to drinking too much water during endurance sports — causes the sodium in your body to become diluted. When this happens, your body’s water levels rise, and your cells begin to swell. This swelling can cause many health problems, from mild to life-threatening. (more…)

Not Afraid to Look


Since April, 2016 thousands of demonstrators have been camping out at the confluence of the Cannonball and Missouri Rivers on the Standing Rock Sioux reservation in North Dakota. These peaceful water protectors—representing more than 200 Native-American tribes, plus many nonnative allies—are demanding a halt to the construction of the Dakota Access Pipeline, which threatens the water and sacred land of the Standing Rock Sioux. Tensions are escalating—on the night of Nov. 20, North Dakota law enforcement deployed water cannons, tear gas and rubber bullets against the unarmed group in subfreezing temperatures. (more…)

Trump’s Pledge to ‘Open Up the Water’ for Valley Farms: Easier Said Than Done

by Craig Miller

“We’re gonna solve your water problems.” –Donald Trump.


California Drought Expected to End After January Inauguration

President-elect Donald Trump might have trouble living up to one of his more sweeping campaign promises in California.

On the stump in Fresno last May, he made headlines for declaring, “There is no drought” here.

It’s a bit unclear from his remarks whether he was voicing an opinion or simply reporting what some farmers told him at a pre-rally gathering. Either way, he was badly mistaken.

Though conditions have improved over much of the state since then, about 73 percent of California remains in some level drought, according to the U.S. Drought Monitor, and nearly 43 percent is still classified in “extreme” or “exceptional” drought, including much of the San Joaquin Valley. (more…)

Water Treatments that Work and Those that Don’t

by Gene Franks


The eminent water treatment specialist Peter S. Cartwright, a man of long experience and unchallenged expertise in the field, recently published a two part article in Water Conditioning and Purification magazine (October and November 2016) that concentrates on some of the shady areas of water treatment. Mr. Cartrwright skips the obvious health-related humbugs like “alkalizers” and concentrates on the technical aspects of genuine water treatment issues like scale prevention, TDS reduction, and removal or inactivation of bacteria and cysts.
