Backflow Preventer Installation Services

Getting the right backflow preventer installed means knowing your system — the pipe configuration, water pressure, connection points, and what local code requires for your property type.

We match each installation to those specifics, using components from Watts and Zurn built for long-term performance.

Properties with water line or drainage needs can combine this service with water line repair, repiping, and sewer line repair in the same visit.

Backflow Preventer Valve Installation

Backflow preventer valve installation starts with identifying cross-connection points and assessing water pressure levels.

From there, our technicians match the right valve type to your system’s specific configuration — whether that’s a reduced pressure zone (RPZ) device, double check valve, or pressure vacuum breaker.

Every installation is pressure-tested on-site to confirm the device is performing to code.

Sewer Backflow Preventer Device Installation

Sewer backups can cause serious damage and health hazards. Installing a sewer backflow preventer device helps stop wastewater from reversing into your property through aging or overwhelmed sewer lines. Regular maintenance from a drain cleaning company in Erie, PA, can also help keep wastewater flowing properly and reduce the risk of recurring drainage problems.

This service is particularly important for:

Properties in low-lying areas
Homes with a history of flooding
Buildings tied into older municipal sewer infrastructure

Our technicians size and install each device to handle real-world flow conditions, and every job is completed to local code requirements.

Backflow Preventer Testing

Annual backflow preventer testing keeps your system performing to code and gives you documentation to back it up when inspections come around.

Many municipalities across Western New York and Northwestern Pennsylvania require certified testing every year — and TJ’s Plumbing & Heating, Inc. handles that process from start to finish.

Backflow Testing and Prevention Services

Our backflow testing and prevention services use calibrated equipment to verify your device is holding up under real operating conditions. Every test covers:

Pressure testing and performance checks
Leak and failure detection
Compliance verification against local code requirements
Documentation prepared for municipal inspection records

Any issues found during testing get addressed on the same visit — we walk you through your repair options and get it handled.

Backflow Preventer Repair and Replacement

A backflow preventer showing signs of wear or failure puts your entire water supply at risk until it gets fixed. Our team diagnoses the problem on-site and determines whether repair or full replacement is the right call for your system. We handle:

Faulty or leaking devices
Failed annual inspections
Aging or outdated systems
Emergency backflow issues

When replacement is the right move, we install devices that meet current safety standards and are built for long-term performance.

Commercial Backflow Services

Commercial plumbing systems carry stricter compliance requirements and less room for downtime.

Our team provides commercial backflow services built around keeping your operations running without interruption and your property inspection-ready at all times.

Frequently Asked Questions

What is a backflow preventer, and why do I need one?

A backflow preventer stops contaminated water from reversing into your clean water supply. Most local codes require one, and properties with irrigation systems, boilers, or fire suppression lines are especially common candidates.

How often should backflow testing be done?

Annual testing is the standard requirement for most properties. Regular testing keeps your system compliant with local regulations and confirms the device is functioning as intended.

What happens if my backflow test fails?

A failed test means the device is no longer blocking contamination effectively. Repair or replacement restores both compliance and the integrity of your water supply.

Do I need backflow prevention for my home or just commercial properties?

Backflow prevention applies to both residential and commercial properties. Homes with irrigation systems, boilers, or any cross-connection between potable and non-potable water lines are subject to the same requirements as commercial sites.
