Homeowners in Bucks, Montgomery, Chester, Berks, and Delaware Counties often ask:

“Can I buy my own water softener, UV light, filtration system, water heater, or well pump online and hire a plumber to install it?”

With online stores advertising low prices, it seems like an easy way to save money. But at Dierolf Plumbing and Water Treatment, we never install customer-supplied equipment, and here’s why this policy protects your home, your water quality, and your wallet:

1. Protect Your Warranty and Avoid Costly Repairs

Most manufacturers require equipment to be purchased and installed by approved professionals for the warranty to remain valid. Systems bought online or from big-box stores often have limited or voided warranties.

If a system fails or leaks, the replacement cost could fall entirely on you. When we supply and install your system, your warranty is protected, and we stand behind both the equipment and the installation. Our 100% Satisfaction Guarantee is the best in the industry.

2. Get the Right System for Your Water Chemistry

Water conditions vary across Southeastern PA. Homes in Berks County may have high manganese, while Bucks County often deals with acidic water. Hardness, iron, pH, sulfur, and well depth differ from one township to another.

Store-bought systems are usually sized using guesswork. Incorrect sizing can lead to:

  • Poor performance
  • Unsafe drinking water
  • Premature system failure
  • Leaks or flooding
  • Low water pressure

We perform a professional water test, evaluate your plumbing, and design a system tailored to your home for optimal performance.

3. Quality Equipment Saves Money Long-Term

Many online systems use non-repairable parts or disposable cartridges. When one piece fails, the entire unit often needs replacement.

We only supply equipment that:

  • Uses repairable, readily available parts
  • Is supported by reputable manufacturers
  • Is built for longevity, not short-term replacement

Better equipment means fewer breakdowns, fewer surprises, and a lower total cost of ownership.

4. Full Accountability and Peace of Mind

If we didn’t supply the product, we can’t guarantee:

  • It wasn’t damaged during shipping
  • Parts aren’t missing
  • It meets Pennsylvania plumbing codes
  • The manufacturer supports it

When we provide the equipment, we take responsibility for selection, installation, warranty, and long-term support, giving you confidence, not confusion.

5. Factory Training Ensures Safe Installation

Many systems require manufacturer-approved training and programming. Incorrect installation can cause unsafe water, high operating costs, leaks, or system failure.

Our fully trained, well-qualified team follows precise procedures to ensure:

  • Safe drinking water
  • Correct programming and calibration
  • Full warranty coverage
  • Optimal performance

Online purchases rarely include full technical documentation, and untrained installers often miss critical steps.

6. Compliance with Local Codes

Some online equipment is not certified for Pennsylvania use or fails to meet township plumbing codes. Installing non-compliant products can lead to:

  • Failed inspections
  • Denied insurance claims
  • Expensive replacements

We install products that are certified, tested, and compliant with local code requirements, protecting your home and property value.

7. Store-Bought Equipment Often Costs More Over Time

Online systems may look cheaper upfront, but long-term costs tell a different story. Homeowners often pay more due to:

  • Frequent repairs
  • Limited or no replacement parts
  • Higher operating costs
  • Poor performance
  • Early replacement
  • Water damage from improper sizing or leaks

Professionally designed and installed systems last longer, perform better, and cost less to own over time.

Our Promise to Southeastern PA Homeowners

Our policy isn’t about making a sale. It’s about delivering a complete service that protects your home, backed by the best customer service possible. When we supply the equipment, we take full responsibility for:

  • Proper sizing
  • Product quality
  • Safe installation
  • Code compliance
  • Warranty protection
  • Long-term support and maintenance

That’s how we deliver the most exceptional service experience possible.

Frequently Asked Questions

1. Can I save money by buying my own water treatment equipment online?

It may seem cheaper upfront, but most store-bought systems have limited warranties, non-repairable parts, and are often incorrectly sized leading to higher long-term costs and expensive plumbing repairs.

2. If I already bought a system, can you install it?

No. To protect your home and avoid liability issues, we only install equipment we supply directly. This ensures full warranty coverage and performance.

3. What if I need a replacement for my existing system?

We’ll evaluate your current system and recommend a replacement that matches your home’s water chemistry and plumbing needs.

4. Are online water systems the same as professional systems?

No. Many online systems use disposable components and one-size-fits-all sizing. Professional systems are built to last and programmed based on your exact water test results.

5. Will hiring a professional installer improve water quality?

Yes. Correct sizing, programming, and installation ensure safer water, longer efficiency, and better protection for plumbing and appliances.
