What Our Backflow Prevention And Testing Includes
Every backflow service visit covers the test, the documentation, and a clear explanation of what we found. If repairs are needed, we quote them before we start.
Work order
Backflow Prevention and Testing- Full Assembly Inspection: We inspect the backflow preventer for leaks, corrosion, and debris before testing. We check the shutoff valves and test cocks to make sure they operate correctly. Any issue that could affect the test result gets noted and addressed first.
- Certified Performance Test: We connect a calibrated differential gauge and run the manufacturer's test sequence for your device type. For an RPZ assembly, that means checking the first check, second check, and relief valve. The test takes 20 to 40 minutes depending on size.
- Repair Or Replacement Quote: If the assembly fails, we explain what failed and what it takes to fix it. We quote parts and labor upfront so you can decide. Common repairs include check valve kits, relief valve discs, and test cock replacements.
- Test Tag And Report: After a passing test, we attach a tag showing the test date and technician information. The report includes the gauge readings and your next test due date.
- Compliance Record Keeping: For property managers with multiple devices, we track test dates and remind you before each one is due. We keep copies of past reports on file so you have a complete compliance history if the water authority asks.

Backflow Prevention and Testing Lancaster OH Explained
Backflow prevention is not paperwork for its own sake. It keeps the water your family and customers drink from mixing with water that has been used. Testing it once a year is how you know it still works.
Backflow prevention and testing Lancaster OH is the work of installing, inspecting, and testing the assemblies that keep contaminated water from reversing into your clean water supply. A backflow preventer is a mechanical valve assembly that stops water from flowing backward through the pipe. We test reduced pressure zone assemblies, double check valves, and pressure vacuum breakers using a calibrated differential gauge, then file the results with the local water authority so your property stays compliant.
Lancaster properties need this because our water system serves a mix of older homes, commercial kitchens, irrigation systems, and industrial sites, and each one creates a possible cross-connection. A drop in main pressure from a water main break or heavy fire demand can pull stagnant water back into the supply. If you have been searching for backflow testing near me Lancaster OH, we handle the test, the tag, and the report in a single trip.
- What it is
- A valve assembly that stops water from flowing backward.
- When it helps
- When pressure drops and contaminated water could siphon back.
- What you get
- A tested device, a tag, and a filed report.
Our Backflow Testing Process
Every job follows the same five steps so you know exactly what to expect from the moment we arrive to the moment you get your report.
Tools And Methods We Use
Each method answers a different question. Together they leave very little to guess.
Used to remove and reinstall test cocks, check valve caps, and fittings on the assembly during repairs. We carry several sizes to fit residential and commercial devices.
Crimps press fittings when we need to replace a section of copper or PEX piping near the backflow assembly. It makes a clean, code-correct connection without soldering.
Push-to-connect fittings used for quick repairs on copper and PEX lines around the assembly. They let us restore water service fast when a line needs replacement.
Electronic listening devices and pressure gauges that help us find hidden leaks that could drop system pressure and trigger a backflow event.

PhotoFailed RPZ Assembly Repaired Same Day
Before: A restaurant in Downtown Lancaster had an RPZ assembly that failed its annual test. The relief valve was leaking and the first check valve would not hold pressure. The health inspection was two weeks away.
After: We replaced the relief valve disc and the first check valve kit the same day. The assembly passed on retest with a differential of 5.2 psi across the first check. We filed the report and tagged the device.

Six-Property Compliance Schedule Set Up
Before: A property manager in Lancaster Heights had six commercial buildings with multiple backflow devices. Test dates were scattered, and two properties had already received violation notices for overdue testing.

Backflow Problems We Solve In Lancaster
Backflow issues range from a failed annual test to a contaminated water supply.
Failed annual backflow test
A failed test means your assembly is not protecting the water supply, and the water authority can issue a violation or shut off service until it…
Missing or expired test tag
An expired tag tells the water authority your device has not been tested on schedule.
Backflow device leaking or stuck
A leaking relief valve or a stuck check valve can waste water, drop your pressure, and fail the next test.
New irrigation system without backflow protection
An irrigation system connected to the water supply without a backflow preventer can siphon fertilizer and pesticides into your drinking water.

Testing your backflow assembly protects your drinking water and keeps you on the right side of local codes.

What Lancaster Customers Say
We needed our backflow assembly tested before a health inspection and the first company we called could not get to us for two weeks. Lancaster Hocking Flow Plumbing came out in two days, tested both devices, and filed the report the same afternoon. The inspector had our paperwork on file before he arrived. That saved us a lot of stress.
Our irrigation system backflow device failed its annual test and the previous company just told us to replace it. These guys opened it up, found a torn check valve disc, and had the repair kit on the truck. The whole thing cost less than a new device and it passed on the retest. They also tagged it and showed me the gauge readings.
I manage six commercial properties in Lancaster and keeping up with annual backflow testing used to be a nightmare. Lancaster Hocking Flow Plumbing set up a schedule, reminds me before each due date, and files every report with the water authority. I have not had a single violation since we started working with them.
