Ever since Constantin Geambasu established Water Rehab in suburban Phoenix, he’s followed a simple but effective business mantra: quality counts.
That philosophy extends further than just the quality of workmanship and the skills of the company’s three technicians. It also includes a very intentional and selective process of choosing the best parts and vendors, which in turn helps enhance repeat business — and word-of-mouth referrals, which he credits for much of his company’s growth since he started out in 2019.
“Anybody can put two parts together and make it look good,” he says. “But when we do projects, everything works like it’s supposed to.”
Take water-treatment systems, for example, which he says are a necessity in the metro-Phoenix area because of poor local water quality. Geambasu prefers Ameriflow Water Systems, which meet his high standards for quality.
“Installing the best systems available took my business to the next level,” he says. “Ameriflow systems are built the way I like it. I choose things that are customized for weather, environment, water quality and so forth — everything has to be taken into consideration. I do not gamble with jobs.”
More specifically, Geambasu doesn’t skimp when it comes to the parts he chooses to use when installing Ameriflow treatment systems. Manufacturers like Ameriflow offer a variety of parts for system installations — things like valve heads, housings, distribution tubes, resins and tanks — similar to a good-better-best ladder of choices. And contractors can choose what parts they want to use, he says.
“They’re like cars — they come with different options,” Geambasu explains. “I pay more for the best options. It’s our job to select what’s best for our customers. Others might just use the cheapest parts they can get by with to save money, but we don’t. And that’s what makes the difference — what makes us stand out. I value quality and our customers, not the money. If you value the quality of work and your customers, the money will come.”
But doesn’t that mean Geambasu has to charge more to maintain a decent profit margin? He says no, noting that his services are priced competitively. But he points out that it’s important to educate customers about the quality of the parts that will be used so they can make sound value judgments when they compare his bids to others’ job quotes.
“Some customers don’t care about quality — they care about a different value,” he says. “People who don’t do their homework aren’t my kind of customers and I’m OK with that. I just try to educate customers about the value of what we do. That’s where my job becomes more than just a service.”
