InstallationUpdated June 26, 2026
Protecting water quality isn't just a box to check for local businesses, it's a code requirement and crucial for public safety in Hampshire. Our municipal supply is drawn from local wells and reaches all types of businesses here in the western suburbs of Chicago. Commercial spaces are required to install and maintain backflow prevention devices, and regular testing isn't optional. If you run a business like a restaurant, school, office, or anything with irrigation or industrial processes, this applies to your plumbing system.
Why Backflow Matters in Hampshire
Backflow happens when contaminated water reverses direction and finds its way back into the clean supply. This can be caused by a sudden drop in water pressure, a burst main, or improper plumbing connections. With Hampshire's mix of older and newer commercial buildings, we've seen backflow risks in everything from small shops to larger facilities.
Code enforcement in our area includes yearly backflow testing for many types of commercial properties. With our flat terrain and clay soils, drainage issues can put extra pressure on systems, especially if there's a sump pump or irrigation tie-in. Businesses without compliant devices risk contamination, fines, or even forced shutdowns until the plumbing is up to standard.
Common Types of Backflow Preventers We Install
- Reduced Pressure Zone (RPZ) Assemblies: Used for high-hazard applications, often required for commercial buildings with chemical feed systems or fire protection setups.
- Double Check Valve Assemblies (DCVA): Suitable for moderate hazard, like sprinkler systems and multi-tenant buildings.
- Pressure Vacuum Breakers (PVB): Typically found on irrigation lines, less common inside the building but critical outside.
We always check that the right device is matched to the level of risk and building code for Hampshire's municipal supply. If we find outdated or improperly installed backflow assemblies, replacement is usually needed to pass inspection.
What Our Backflow Installation Includes
Our licensed crew handles the full process:
- We evaluate your water supply entry and identify all cross-connection points.
- Our team selects the right backflow preventer for your application, RPZ, DCVA, or PVB, based on local codes.
- We install the device with unions and shutoffs to make future testing and maintenance straightforward.
- We file the required paperwork and coordinate with inspectors after installation.
We've worked in facilities using everything from cast iron and galvanized pipes to newer PEX or copper. If you own or manage an older building, we can tie backflow installation into pipe repair and repiping work if corrosion or leaks are present. We also keep an eye out for sump pump discharges and other cross-connections that often get overlooked.
Warning Signs a Business Needs Immediate Backflow Attention
- Unusual drops in water pressure or visible water hammer in supply lines
- Any sign of discolored or odd-smelling tap water
- Plumbing fixtures with unexplained leaks or backup
- Missing, corroded, or tampered backflow devices
- Annual inspection sticker expired or missing
If your building's backflow preventer hasn't been inspected in the last year, or if you're unsure of its location or condition, schedule a test before it's flagged during a routine inspection. Our crew can also coordinate leak detection and repair if there are signs of cross-contamination or water escaping the system.
What to Expect from Annual Backflow Testing
Annual testing involves checking for valve operation, leaks, and pressure differences across the assembly. We use calibrated gauges, document all readings, and submit test reports to Hampshire's municipality as required. If replacement parts are needed for valves or seals, we handle that on the spot. Regular testing goes hand-in-hand with other maintenance like drain cleaning and sump pump services in commercial spaces to keep the system safe and code compliant.
Handling Older Pipes and Seasonal Issues
Some Hampshire buildings have galvanized or aging clay-tile lines, which are more prone to corrosion and leaks. Local freeze-thaw cycles each winter can also stress buried assemblies and exposed valves. Our team checks for insulation, proper placement, and thermal expansion controls around the backflow preventer so pipes don't burst or shift during temperature swings. When necessary, we coordinate with our sewer line services or other plumbing work to make sure your backflow installation fits the rest of your system and won't be disrupted by drainage or foundation repairs.
