Certified Backflow Testing — Done Right by a Local Master Plumber
If your water authority sent you a notice that your backflow prevention assembly is due for annual testing, we can test it, fill out the paperwork, and file the report for you. Angermeier Plumbing is a PA-certified backflow tester and Registered Master Plumber (PA HIC #5653) working across Bucks County and eastern Montgomery County, PA — restaurants and commercial buildings, irrigation and lawn-sprinkler systems, fire suppression lines, boiler make-up feeds, and residential RPZ and double-check assemblies.
A backflow preventer is the only thing keeping non-potable water — irrigation water sitting in a lawn line, boiler treatment chemicals, a soda-machine carbonator, fire-line water — from siphoning back into the drinking water supply when pressure drops. That is why the testing is annual and why the authority wants a certified tester's gauge readings on file, not a plumber's word.
We show up with a calibrated differential-pressure test kit, run the test in one visit, and tell you on the spot whether the device passed. If it failed, we can usually rebuild it the same trip.

Our Process
How a Backflow Test Works
1. Locate and identify the assembly
We record the make, model, size, and serial number of the device along with its hazard type and location — the water authority's form needs all of it.
2. Notify and isolate
The test briefly shuts water downstream of the device, so we schedule around your business hours or irrigation schedule and let you know how long you'll be off.
3. Run the certified gauge test
A calibrated differential-pressure gauge is connected to the test cocks to check each check valve and the relief valve against the required pressure differentials.
4. Rebuild if it fails
Most failures are worn rubber — check discs, springs, or the relief-valve diaphragm. We carry common rebuild kits so a failed device can usually be repaired and retested the same visit.
5. Complete and file the report
We sign the certified test report with the gauge readings and calibration data and file it with your water authority or township so your record stays current.
What We Handle
Devices & Customers We Handle
RPZ Assemblies
Reduced pressure zone assemblies on high-hazard connections — restaurants, medical and dental offices, boiler feeds, and chemical-treated systems. Tested, rebuilt, and certified.
Double Check Valve Assemblies
DCVA units on lower-hazard connections such as fire lines and some irrigation services. Annual testing plus repair and replacement when checks no longer hold.
Irrigation & Lawn Sprinklers
Initial certification for new systems and annual spring testing before start-up, coordinated with your irrigation contractor's schedule.
Commercial & Restaurant
Kitchen, carbonator, mop-sink, and grease-line hazards. We test the whole set of assemblies in one visit and hand you one packet of filed reports.
Fire Line Assemblies
Testing and repair on fire suppression backflow devices, coordinated with your sprinkler contractor so the system is returned to service properly.
Device Repair & Replacement
Rebuild kits for common Watts, Febco, Wilkins, and Zurn assemblies, plus full replacement when a device is obsolete, frozen, or beyond rebuild.
Southampton, PA
Backflow Prevention Testing in Southampton, PA & Nearby Towns
We're based in Upper Southampton, so most backflow testing calls in Southampton, Warminster, and Richboro get scheduled within a few days of your authority's notice. The commercial strips along Street Road and County Line Road are mostly RPZ assemblies on restaurant and salon services, and those buildings usually have more than one device — we test them all in one visit and hand you a single packet of filed reports.
Residential work here is mostly irrigation. Lawn systems installed through the 1990s and 2000s across Southampton, Richboro, and Holland were fitted with double-check and pressure-vacuum-breaker assemblies that sit outside and freeze. We test at spring start-up, rebuild the ones that fail, and replace the ones that split over winter.
Bring the notice you received with you when you call — the device serial number and the authority's due date tell us what kit to load before we head out. Call 215-364-0133.

Answers
Certified Backflow Testing FAQs
How much does backflow testing cost in Bucks County, PA?+
It depends on the number and size of the assemblies and whether the device needs a rebuild. A single residential or irrigation assembly is a flat test fee; multi-device commercial buildings are quoted per site. Call 215-364-0133 for a firm number before we schedule.
How often does a backflow preventer have to be tested?+
Most Bucks and Montgomery County water authorities require certified testing once every 12 months, plus a test any time the device is installed, repaired, relocated, or replaced.
Who files the test report with the water authority?+
We do. We complete the certified test report with the gauge readings, tester certification number, and gauge calibration data, and submit it to your water authority or township so your file stays current.
What happens if my backflow device fails the test?+
We show you which check or relief valve failed and what it will take to fix it. Most failures are worn rubber parts, and we carry rebuild kits for common Watts, Febco, Wilkins, and Zurn assemblies so we can repair and retest in the same visit. Obsolete or frozen devices get a replacement quote.
How long does the water stay off during a backflow test?+
Usually 15 to 30 minutes per device. For restaurants and commercial buildings we schedule around your hours so the shutdown lands outside your busy period.
Do irrigation systems need backflow testing?+
Yes. Lawn irrigation is a cross-connection hazard, so the assembly needs initial certification when installed and annual testing after that — typically at spring start-up.
Are you certified to test backflow preventers in Pennsylvania?+
Yes. Testing is performed by a PA-certified backflow tester using a calibrated differential-pressure gauge, and we are a Registered Master Plumber, PA HIC #5653.
What areas do you cover for backflow testing?+
Southampton, Warminster, Warrington, Feasterville, Bensalem, Yardley, Richboro, Huntington Valley, Newtown, Doylestown, Jamison, Hatboro, Horsham, Willow Grove, Ambler, Chalfont, North Wales, and surrounding Bucks and Montgomery County, PA communities.
