Plumbing Services That Safeguard Your Systems and Your People

At Bassett Mechanical, we deliver more than plumbing repairs—we provide peace of mind. Our plumbing services involve proactive maintenance, regulatory compliance, and long-term system efficiency. Our team ensures your plumbing infrastructure is safe, reliable, and built to last.

We offer a full suite of services, including cross-connection surveys, backflow testing, and preventive maintenance, to help you stay compliant and avoid costly disruptions.

Cross Connection Surveys | Protecting Your Potable Water Supply

Cross connections—points where clean water can unintentionally come into contact with contaminants—pose a significant risk to your facility. Our certified technicians conduct thorough cross connection surveys to identify and eliminate these hazards before they become liabilities.

We evaluate your plumbing system, document potential risks, and recommend corrective actions to ensure local and state regulation compliance. This service is essential for maintaining water quality and protecting your employees, customers, and operations.

What Is a Cross Connection?

A cross connection links the potable (clean) water supply and a non-potable source, where contaminants could potentially enter the drinking water system. Our survey includes an inspection of your building’s water system—from the source to the last free-flowing tap—to identify and mitigate these risks.

Survey Requirements

Most municipalities require cross connection surveys every 2–3 years, depending on your business type and risk level. You’ll receive a notification letter when your facility is due.

What to Expect from a Bassett Cross Connection Survey:

Inspection & Identification – Complete inspection of water supply to identify any potential hazards and cross connections
Risk Assessment – Each cross connection is evaluated based on the type and severity of potential contaminants.
Backflow Prevention Evaluation – We inventory and assess all existing backflow prevention assemblies.
Recommendations – We provide clear guidance on eliminating or controlling cross connections.
Documentation—You’ll receive a detailed report outlining each cross-connection’s location, classification, and status. We will also provide the municipality with the necessary documentation.

Stay compliant and protect your water supply. Contact Bassett today to schedule your cross-connection survey.

Backflow Testing | Compliance, Safety, and System Integrity

Backflow occurs when water flows in reverse, potentially allowing contaminants to enter your clean water system. This can happen due to changes in water pressure and poses a serious risk to public health. Backflow prevention devices are installed to stop this reverse flow and must be tested annually to ensure they work correctly.

Our Backflow Testing Services Include:

Annual Testing & Certification – Per Wisconsin plumbing code, we test backflow prevention assemblies at installation, after repairs, and annually.
On-the-Spot Repairs – Our service vehicles are stocked with standard parts to minimize downtime.
State Reporting & Documentation – We submit test results to the State of Wisconsin on your behalf.
System Mapping & Tracking – We maintain detailed records of device locations, conditions, and service history.
Flexible Scheduling – Testing is typically completed in one visit during business hours (Mon–Fri, 7:00 AM–3:30 PM).

Contact us. Stay compliant with confidence. Bassett’s licensed technicians help you meet regulatory requirements while protecting your facility from costly disruptions.

Preventive Maintenance | Your Customizable Tasking Sheet

Our plumbing maintenance program is built around a detailed tasking sheet that covers every critical component of your system. This checklist allows you to “pick and choose what best fits you,” offering flexibility while ensuring nothing is overlooked.

Services Include:

Fixture inspections and leak checks
Drain flow and water seal verification
Water heater flushing and anode rod inspections
Sump and ejector pump testing
Ice machine
Water softener and water filitration systems
Roof drain inspections

This proactive approach reduces service calls, extends equipment life, and keeps your facility running smoothly.
