Oatey Co. remains committed to supporting, advancing and retaining its operations associates through world-class, on-the-job training, as well as educational opportunities.
In 2016, Oatey launched its first-ever Industrial Maintenance Apprenticeship Program, designed to promote the advancement of operations associates into higher-skilled positions that are more aligned with their long-term career goals. It also leverages additional career-development opportunities for the company’s more experienced associates, allowing them to hone their leadership, training and mentoring skills, while working with a diverse group of apprentices.
Oatey’s registered apprenticeship program, which is based at its Cleveland Manufacturing facility and led by Maintenance Supervisor Ruben Santos, is sponsored by Manufacturing Works and regulated through the State of Ohio. As the sponsor, Manufacturing Works helps manage the program and provides Oatey with continuous expert guidance about how to offer the most cutting-edge resources for associates.
“Since its inception, the program has received a tremendous response, and associate participation continues to grow,” says Santos.
To date, the program has included three groups (or cohorts), including a total of six registered apprentices. Every other year, Oatey anticipates adding a new cohort to the program roster. “We continue to maintain 100% retention of associates who participate in the apprenticeship program,” Santos explains.
Oatey’s inaugural group of two apprentices successfully completed all of the program’s training requirements in 2020, and two deserving individuals earned the title of Journeyman. After graduating from the program, these individuals have gone on to advance their careers.
“Our Journeymen continue to embody the spirit of Oatey and set a positive example for fellow associates,” says Santos. There are currently two active cohorts with four apprentices making their way through the program. All current apprentices are from underrepresented groups (Hispanic and African American). Oatey also recently welcomed its first female apprentice, who will graduate as part of the third cohort. Oatey’s commitment to small cohorts ensures personal attention to the apprentices’ development.
When the need for new apprentices is determined, positions are opened and the application, recruiting and selection process begins. The four-year program welcomes applications from any active operations associate in good standing, including those at Cleveland Manufacturing and Distribution facilities; however, the selection process for admission is rigorous. Applicants must display a strong work ethic, reliable attendance record, commitment to Oatey, and passion for skilled technical work.
Prior to acceptance, new candidates for apprenticeship must provide evidence of earning their high school diploma or GED, and complete a Mechanical Aptitude Test and a college admissions placement exam to ensure successful completion of the program.
The Industrial Maintenance Apprenticeship is a hybrid program that offers both in-classroom instruction with college credit and on-the-job training (OJT). Oatey partners closely with Cuyahoga Community College (Tri-C) to deliver a robust, specialized curriculum to complement the OJT that takes place at the Oatey facility. Every apprentice must complete up to 10,000 hours of OJT.

For a boiler to operate properly, the liquid it contains must maintain the correct pH levels. If the pH level is not regularly tested and properly maintained, minerals can build up on the inside of the components. Or the water can turn acidic and attack the boiler’s metallic components and piping from the inside out, causing rust to form.
Scale or rust buildup reduces system performance over time. Enough buildup can essentially stop the operation of the system altogether.
Understanding pH levels in hydronic heating systems
Historically denoting “potential of hydrogen,” pH is the measure of how acidic or basic the water inside a hydronic heating system is. According to usgs.gov, the universal reading for pH goes from 0-14, with 7 being neutral. Less than 7 indicates acidity; greater than 7 indicates a base.
- Examples of items that have a pH of less than 7 are black coffee (pH=5), grapefruit juice, soda, or tomato juice (2.5-3.5), and lemon juice or vinegar (2).
- Examples of items that have a pH of greater than 7 would be seawater (8), baking soda (9.5), ammonia solution (10.5-11.5), and liquid drain cleaner (14).
pH is an important indicator of water that is changing chemically. Boiler systems need to have the perfect pH level balance. If the pH goes too high or too low, it can drastically impact a system.
The correct pH level will depend on the metallic composition of the heat exchanger. Some recommended pH levels range from 8 to 8.5. We recommend checking the boiler installation and operation manual to determine the acceptable pH range. Systems with a cast iron, stainless steel or copper exchanger are resilient and usually have a wide range of acceptable levels. Aluminum is more prone to corrosion and may require a specific pH.
Performing pH testing
Do a visual reading by opening the drain valve and bleeding off some liquid. If it appears clear, proceed with a pH test. As mentioned above, the correct pH level depends on the composition of the heat exchanger.

How to test pH levels
You can buy test strips that provide a color-coded readout. If you need a more precise reading for an aluminum system, use a digital pH meter.
Hercules Cryo-Tek Test Strips, available in packs of 6 to 10 color-coded and disposable test strips, can simultaneously check both the level of freeze protection (propylene glycol) and the level of corrosion protection in a system.
To conduct the test, drain some water from the boiler and then dip one of the pH test strips into the sample. Once a bit of color starts to pop up, compare the strip to the color chart to determine the pH level.

How often should you test pH levels?
These are closed systems, so there are usually no external signs of corrosion, making it difficult to spot an equipment leak — unless, of course, water is visibly running onto the floor. (If so, corrosive water inside the boiler is a likely cause.)
This general lack of immediate visibility is why it’s important to test hydronic systems annually. If your locale has hard water or there are conditions causing the water to be more acidic, testing should be done twice a year.
The lack of visibility is also why sampling the water for a test, as described above, is a must: It is the best way to tell if anything is wrong. If rust or sludge appears in your sample, you should test and replace the water.

What happens if a boiler’s pH is too high or too low?
If you find the pH levels too high, you’ll start to notice scale or limescale buildup in the boilers. Too much mineral buildup will restrict the system’s water flow. Essentially, the effectiveness of the boiler is lessened.
If the pH levels are too low, the water has turned acidic. This leads to rust and corrosion — a serious problem since boilers are typically made of copper, cast iron, and aluminum. As mentioned earlier, enough corrosion can stop system operation altogether.

How to balance out the pH
Maintenance managers or contractors can use a corrosion inhibitor to balance out the pH — a seamless fix. However, if the buildup or corrosion has been going on for several years, the system will probably not recover with this treatment. Instead, you’ll have to use a cleaner to flush the system to maximize boiler efficiency.
The Hercules® Boiler and Heating System Cleaner is formulated to clean and condition both steam and hot-water hydronic systems by removing rust, scale, and sludge. The cleaner can also free and lubricate zone valves and help stop priming and foaming with a special anti-foam agent. Ultimately, it is a liquid cleaner and corrosion-prevention treatment.
The Hercules® Sludgehammer System Restorer & Noise Reducer is another option for maintaining a boiler system. More aggressive than the system cleaner, it also cleans and reduces kettling (bubbling and banging), while restoring system efficiency. Maintenance managers or contractors can pair this product with a corrosion inhibitor for annual heating system-maintenance checks.
If the pH level is off:
- Drain about a gallon of liquid from the boiler and dispose of it.
- Fill a container with a quart of corrosion inhibitor, such as Hercules® Sludgehammer™ Universal Corrosion Inhibitor, and 3 quarts of fresh water. Pump it back into the system and allow it to circulate for about a half-an-hour.
- Test again. Usually, a single dose of inhibitor does the job, but if the reading is still too low, repeat the process

In conclusion, you must test the pH of boiler systems to maximize their efficiency, using products that can make monitoring pH levels simple and easy. If this testing uncovers damage to the system, there are also ways to alleviate and fix that damage.
But regardless of your boiler’s condition, Oatey products can offer a solution. For more information, go to Oatey.com for their heating chemicals and antifreeze products/resources.
