When it comes to protecting your home’s water and plumbing systems, you have no shortage of contractors to choose from. A quick search might turn up a dozen options nearby—plumbers, water treatment “specialists,” even big box stores offering installation deals.
But here’s the truth: not all contractors are created equal.
At Dierolf Plumbing and Water Treatment, we’ve spent years fixing the mistakes of others—improperly sized systems, poorly installed equipment, or water problems that were never truly diagnosed in the first place. That’s why we believe education is just as important as installation. And it’s why we created this guide to show you what makes our approach different.
Expertise That Goes Beyond the Basics
Most plumbers know how to connect a pipe or replace a fixture—but when it comes to water quality, things get far more complex. At Dierolf, our team isn’t just licensed and experienced in plumbing—we’re also certified by the Water Quality Association (WQA), the industry’s most respected authority on water treatment.
WQA certification isn’t a casual credential—it’s earned through rigorous training, ethical standards, and a deep understanding of water chemistry and treatment best practices. When we recommend a system, it’s based on real data and sound science—not a sales pitch.
A Team That Specializes in Wells
If your home relies on a well, you need more than just a general plumber. You need someone who understands yield, pressure, drawdown, pump sizing, and water chemistry. At Dierolf, we’ve built our reputation as Eastern Pennsylvania’s go-to well experts, with licensed inspectors and technicians who are trained to spot issues before they become problems.
While many contractors shy away from wells, we’ve helped thousands of buyers, sellers, and homeowners navigate everything from well inspections to pressure problems.
Water Testing That Actually Means Something
It’s shocking how many contractors install water treatment systems without ever testing your water—or worse, using unverified test strips as their “analysis.”
At Dierolf, we begin with a lab-based water test to determine exactly what’s in your water, from minerals and acidity to chlorine and PFAS. We then design a system that treats the specific issues present in your supply—not a one-size-fits-all solution.
And because we follow WQA best practices, we’re confident that what we install is built to last and truly improve your water.
Licensing That’s Public and Proven
Unlike many contractors, we don’t just claim to be licensed—we invite you to look it up for yourself. Dierolf Plumbing and Water Treatment employs licensed Master Plumbers, ensuring that all work complies with code, protects your investment, and is held to the highest professional standards.
Unfortunately, many plumbing and water treatment businesses operate without these credentials—and homeowners often pay the price in the form of failed inspections, water damage, or code violations.
A Service Experience That Speaks for Itself
We’ve heard it all before: “They installed the system, and then I never heard from them again.” That’s not how we do business.
At Dierolf, we pride ourselves on delivering the most exceptional service experience ever. That means:
- Upfront pricing
- Transparent, pressure-free recommendations
- Complimentary consultations and follow-ups
- A genuine desire to help you understand your options
It’s no accident we have over 1,000 five-star reviews. It’s the result of consistently doing things the right way.
Compliance and Real Estate Support
If you’re selling or buying a home with a well, or need DEP water testing for a commercial or residential property, you need someone who knows the regulations inside and out. We’ve helped thousands of real estate transactions move forward quickly with accurate testing, clear reports, and fast remediation when needed.
Most contractors won’t touch this kind of work. We’ve built a specialty around it.
Final Thoughts: The Contractor You Hire Matters
It’s easy to assume that all plumbers or water treatment companies offer the same thing—but the reality couldn’t be more different. Between licensing, testing, product selection, and long-term service, the gaps are wide.
Here’s what you get with Dierolf Plumbing and Water Treatment:
- Licensed Master Plumbers you can verify
