How to start as a backflow tester in Arkansas today

Last updated 2026-08-18

Do you need a license to be a backflow tester in Arkansas?

You need a tester credential a water system will accept, and you need an Arkansas plumber license if you install or repair the assembly. Arkansas does not hand out one statewide backflow tester license the way some states do. Confirm both paths with the Arkansas Department of Health and the utility before you advertise.

People type backflow tester arkansas into a search bar and expect a single card. That is the myth. Public water systems here sit under the Arkansas Department of Health Public Water System Supervision program. That is how the state carries out the federal Safe Drinking Water Act. ^[3][4] The water system has to keep the mains clean. A cross connection is one way the mains get dirty.

The U.S. EPA published its Cross-Connection Control Manual as EPA 816-R-03-002 in 2003. ^[1] The manual's definition is the one I still hear in class. "Backflow is the undesirable reversal of flow of water or mixtures of water and other liquids, gases or other substances into the distribution pipes of the potable supply of water from any source or sources." ^[1]

Testing an assembly is not the same job as installing one. Testing is a field check with a differential pressure gauge, a signed report, and a copy to the water purveyor. Installing or repairing the device is plumbing work.

The Arkansas Department of Health Plumbing and Natural Gas Section licenses master, journeyman, and apprentice plumbers. ^[5] Arkansas Code § 17-38-301 is the license required section. Read the current text before you cut a pipe. ^[6]

If you only want to test, start with the water department, not the plumbing board. If you want to hang devices, you are in the plumber lane. Plenty of testers do both. Plenty should not, at least not in year one.

I would not print State Licensed Backflow Tester on a truck until a real person at ADH or the city has told you what paper they want. Those words get people in trouble.

How much does it cost to start as a backflow tester in Arkansas?

Startup cash is the course, the gauge kit, calibration, insurance, and whatever the city charges to list you. There is no single official Arkansas starter price. Course tuition and kit prices move. Confirm every fee with the school, the water system, and ADH.

The tester class (ASSE 5110 or another card your target utility names) is the first check you write. Schools quote their own tuition. I will not invent a number. Call two providers and ask what Little Rock, Fayetteville, Fort Smith, and Jonesboro actually take. Out of state online only promises are usually a waste.

A differential pressure test kit is the second check. New midrange kits commonly land in the low thousands of dollars. I have seen people overbuy computerized kits they do not need. A clean analog or simple digital kit plus a current calibration certificate beats a fancy box. Budget annual calibration. Labs set their own prices.

Then come the quiet costs. General liability. Some cities want to see it before they add you to the tester list. If you have employees, workers compensation is a separate conversation. I am not quoting premiums. Shop them.

Business paper is cheap next to the kit. The IRS does not charge for an EIN. "Applying for an EIN is a free service offered by the Internal Revenue Service." ^[7] Arkansas Secretary of State business filings have published fees. Read the current forms and fees page. Do not trust a blog for that dollar figure. ^[9] If you sell taxable services or parts, the Department of Finance and Administration runs sales and use tax. Combined city and county rates sit on top of the state rate. Look up your shop address on the DFA tables. ^[8]

Waste of money: paying a middleman for a license package that is just a reprint of public forms. Also a waste: a vinyl wrap on the van before you are on two tester lists.

Cost pile	Who sets it	What I'd do
Tester course	The school	Call two, pick the one local utilities name
Gauge kit and calibration	Vendors and labs	Buy used only with a fresh cert
City tester listing	Each water system	Ask before you pay anyone else
ADH plumber license	ADH Plumbing	Only if you will install or repair
EIN	IRS	File it yourself, it is free
Entity filing	Arkansas SOS	Confirm the current fee

How long does it take to become a backflow tester in Arkansas?

Plan on a one week tester course plus however long your first water system takes to list you. If you also need a journeyman or master plumber license, that is a multi year apprenticeship under ADH rules, not a weekend. Nobody should promise you a start date.

ASSE style tester courses are usually taught as a multi day block with a written exam and a hands-on exam. Schools set the calendar. I have no honest statewide processing clock because Arkansas is not issuing a single tester permit with a published queue.

The slow part is local. You finish class. You get the card. You send the card, a sample report, maybe an insurance certificate, to the water system you care about. Some lists update fast. Some sit on someone's desk. Call. Do not email once and wait.

If your plan is test and repair, stop and read the plumber path. ADH plumbing licenses are a different clock. Apprentice time, exam, application. Confirm current hour and exam rules with the Plumbing and Natural Gas Section. ^[5] I will not invent those hours.

People ask how this compares to nearby states. Alabama is its own paper path. If you might work the border, read how to start as a backflow tester in Alabama before you assume the same card travels.

Federal rules also do not give you a timer. 40 CFR 141.2 is the federal definition section for a public water system under the National Primary Drinking Water Regulations. ^[2] It does not say how many days Arkansas has to put you on a tester list. That silence is the point. Local paper wins.

What certification do Arkansas water systems actually accept?

Most Arkansas water systems want a current backflow assembly tester credential from a known program such as ASSE 5110, and they want your name on their list. Ask the utility in writing. Do not guess from a Facebook group.

ASSE 5110 is the tester professional qualification the trade actually talks about. USC's Foundation for Cross-Connection Control and Hydraulic Research also runs tester training and publishes the Manual of Cross-Connection Control. ^[10] ABPA has a tester certification path some utilities know. ^[11]

I would take ASSE 5110 unless a specific Arkansas city told me they want USC or ABPA instead. Taking three cards in year one is a waste.

Federal drinking water rules sit underneath all of this. The water system, not you, holds that legal duty. You are the person they allow to test private assemblies so they can show a cross connection program. ^[2][3]

Get the acceptance in an email from the cross connection person. Save it. If they change staff, you still have the email.

Schools will try to upsell specialist or repairer credentials on the same week. The repairer card does not replace an ADH plumber license in Arkansas. Buy it later if a utility asks. Most will not ask in your first season.

Do you need an Arkansas plumber license just to test?

Not if you are only testing and the water system will list a non plumber tester. Yes if you break the seal, repair, replace, or install. Confirm that line with ADH Plumbing and with the city inspector, because local practice is not always written clearly.

This is where people get sideways. A test is data. A rebuild is plumbing. Swapping a failed RP for a new one is plumbing. Moving the assembly is plumbing.

ADH is the plumber licensing agency. ^[5] Title 17, Chapter 38 of the Arkansas Code is the plumbing chapter. Section 17-38-301 is the license required rule. ^[6]

If you are already a journeyman or master, you still need the tester credential. A plumber license is not a magic test card. I have watched licensed plumbers fail the hands-on gauge work because they never practiced.

If you are not a plumber and you want repair revenue, you are signing up for apprenticeship time. That can be the right long game. It is a bad surprise if you thought testers just fix it in the field on day two.

California runs a tighter statewide tester model than Arkansas. If you are comparing systems, how to start as a backflow tester in California shows the contrast.

How do you get listed with a city or water utility in Arkansas?

You call the water system's cross connection or backflow person, ask for the tester application, and send exactly what they name. Each utility keeps its own list. One listing does not cover the state.

Little Rock area work usually means dealing with Central Arkansas Water. Fayetteville, Fort Smith, Jonesboro, Pine Bluff, Conway, Rogers, Springdale, and the smaller systems all have their own habits. Some want a copy of your tester card, a photo ID, and a W-9. Some want you to sit through their orientation. Some charge a listing fee. Confirm it. I will not invent that fee.

I would pick two systems you can actually drive every week. Get on those lists. Then expand. Statewide tester is a marketing line, not a legal status in Arkansas.

Ask them which report form they want. Some still want paper. Some want a portal. If you invent your own pretty PDF and they want their form, you will redo the work.

Keep a folder (digital is fine) with your current tester card, calibration cert, insurance cert, each city's approval email, and every test report for at least as long as that utility says. If they have no retention rule, I keep five years. That is my habit, not a statute I can cite.

If a utility requires you to live in district, believe them. Argue after you have other lists.

What equipment and paper do you actually need in year one?

You need a calibrated differential pressure gauge kit, the fittings for RP, DC, PVB, and SVB assemblies, a way to submit the water system's report, and a current tester card. You do not need a new truck or a high dollar data logger.

Kit contents people forget: extra hoses, adapters for odd test cocks, a small bucket, a towel, a flashlight, and a backup analog gauge if your primary is digital. Test cocks on old Arkansas assemblies are often ugly. You will leak on yourself. Wear stuff you can wash.

Calibration is not optional. If your gauge is out, your report is junk, and the utility can drop you. Get the interval from the lab and from the city. Annual is the usual ask.

Paper path: class certificate, wallet card, calibration, insurance, city listing letters, test reports, invoices, and if you repair, your ADH plumber license and job permits as required.

If you want that paper stack in one place, ASSEPath sells a $149 one-time ASSE 5110/5115 Tester Kit. You can also build the same folder yourself. I would not delay class to wait on any kit.

Tools that are a waste in month one: a full repair parts van, and branded shirts for a crew you do not have.

How do you set up the business legally in Arkansas?

Get an EIN from the IRS for free, decide if you need an Arkansas entity with the Secretary of State, and ask DFA whether your services or parts are taxable at your location. Confirm city privilege or occupational licenses with the clerk. I would not hire a pricey business launch coach for this.

Sole prop is how a lot of testers start, especially if they already work under a plumbing shop. An LLC is fine if you want the entity. File it with the Arkansas Secretary of State and read the current fee on their forms page. ^[9] Then keep the entity alive. Annual reports matter.

The IRS treats you as self employed if you are not a W-2. That means estimated taxes and a Schedule C world. Use the IRS self employed pages and a real bookkeeper if numbers are not your thing. ^[7]

Sales tax is the part testers mess up. Testing labor and parts are not always taxed the same way. I am not your tax advisor. Ask DFA or a CPA who actually does Arkansas sales tax. ^[8]

City business licenses are real in some Arkansas towns and ignored in others until you get a letter. Call the clerk. It takes twenty minutes.

Insurance: general liability first. Ask the water system the minimum. Errors and omissions is worth a quote once you are writing a lot of reports. I would not buy a huge policy suite on week one.

If you ever bid construction install work over the Contractors Licensing Board threshold, stop and read ACLB rules. Testing a small assembly is not the same as contracting a building. Confirm the current dollar trigger with the board. I am not printing a number the legislature can move.

Should you test only, or install and repair too?

Test only if you are new and you are not already a licensed Arkansas plumber. Add install and repair only after ADH says you can legally do that work. Repair pays more per stop. It also puts you under plumbing law.

Path	Paper you need	Revenue shape	My take
Test only	Tester card plus each utility list	Seasonal, many small stops	Start here
Test and repair	Above plus ADH plumber license	Fewer callbacks, parts markup	Only if you already plumb
New construction install	Plumber license, maybe contractor license	Project bids and waiting	Not a year one plan

Repair is where testers daydream. Failed RPs on old restaurants. That work is real. It is also how unlicensed people get a visit from the plumbing inspector.

If you already hold the plumber license, get the tester card and go. You are the person this trade is built for.

Alabama's license story is not Arkansas. Do not copy another state's truck lettering. See backflow tester license in Alabama if you work that line.

What does first-year work look like in Arkansas?

First year is commercial assemblies, a few industrial sites, and a lot of driving between towns if you chase every lead. Irrigation devices pop in spring. Restaurants and medical offices are year round. Nobody has clean public data on average tester revenue in Arkansas.

I would build the book from property managers, mechanical contractors, and the water system's failed-test letters (where they will talk to you). Cold calling every church is a grind. Being the person a plumber calls when they do not want to own a gauge is easier.

Pricing: I will not publish a fake statewide test fee. Cities and competitors set the street price. Call three testers as a customer if you must. Then decide if you can live on that number after gas and calibration.

BLS tracks plumbers, pipefitters, and steamfitters, not backflow testers as a separate job. Use those tables for a labor market snapshot, not as your price list. ^[12]

Summer is hot on an Arkansas pad next to a grease interceptor. Winter still has indoor devices. The work is physical and repetitive. If that sounds dull, you will hate the job.

How do you keep the credential and stay legal after year one?

Recertify on the cycle your card uses, keep the gauge in calibration, and stay on every list you still want work from. Most ASSE style tester credentials run on a multi year cycle the school will print on the card. Confirm the date. Do not let it lapse in June when every irrigation device is due.

When the card renews, send the new copy to each utility. They will not hunt you down.

If you hold an ADH plumber license, that has its own renewal. Different desk, different fee, different late penalty. ^[5]

Keep CE if your cert body requires it. Do the hours. The one day recert class is cheaper than retaking the whole week.

If you move counties, redo the local list. Arkansas is not reciprocity in a box even inside the state.

For a different state model, how to start as a backflow tester in Arizona is a useful contrast, not a template.

What should you skip so you do not waste money?

Skip anyone selling a fake Arkansas backflow tester license. Skip a new truck. Skip three certifications. Skip bidding general construction. Do the class, the kit, two city lists, and a simple invoice.

Also skip waiting for a state website to give you a start date. That page is not coming.

If you later want a single packet of forms and checklists, see /start. ASSEPath is an independent publisher, not a law firm and not a service company. This guide works without that packet.

Read backflow tester license in California only if you like seeing how a big state over builds the same job. Then come back and call your Arkansas water department.

Frequently asked questions

Do you need a license for backflow tester in Arkansas?

You need a tester credential the water system accepts, plus an ADH plumber license if you install or repair. Arkansas does not issue one statewide tester card. Call ADH Plumbing and the utility. Do not advertise a state tester license they did not give you.

How much does backflow tester cost in Arkansas?

There is no official starter price. You pay course tuition (set by the school), a gauge kit (often in the low thousands new), calibration, insurance, and any city listing fee. An EIN is free from the IRS. Confirm SOS and ADH fees on their current pages. I would not buy a new truck in month one.

How long does backflow tester take in Arkansas?

The tester class is usually a multi day course plus exams. Listing with a water system can be quick or slow. A plumber license, if you need one, is a multi year apprenticeship under ADH rules. Confirm current course dates with the school and current plumber hours with ADH. No one can honestly guarantee a start week.

Can I test backflow in Arkansas with only ASSE 5110?

Often yes for test-only work, if that water system lists ASSE 5110 testers. You still have to apply to each utility. ASSE 5110 does not let you install or repair unless you also hold the right ADH plumber license. Get the utility's rule in writing.

Does Arkansas accept ABPA or USC tester cards?

Some systems will. Some want ASSE 5110 by name. USC and ABPA are real programs. Ask the cross connection staff before you enroll. I would not collect three cards unless a city demanded a second one.

Do I need a plumber license to test backflow in Little Rock?

If you are only testing and the system that serves that property will list a non plumber, you may not need the plumber license for the test itself. Repair and install still sit under ADH plumbing rules. Confirm both desks. Local practice can be stricter than the statute.

How often do I recertify as a backflow tester in Arkansas?

Follow the date on your tester card and the school that issued it. Many industry cards run on a multi year cycle. Arkansas does not publish one statewide recert calendar for testers. Send every new card to each utility that lists you. Do not let calibration lapse either.

What test kit do I need to start in Arkansas?

A calibrated differential pressure kit that can test RP, DC, PVB, and SVB assemblies, plus hoses and adapters. Ask the water system if they care about brand. I would not start with the most expensive computerized kit. A current calibration certificate matters more than the case color.

Can I work statewide with one registration?

No. Each public water system keeps its own tester list. A listing in Fayetteville does not put you on a Fort Smith list. Build two lists you can drive, then add systems. There is no Arkansas statewide tester roster that replaces local approval.

Do I need a contractor license to test backflow?

Usually not for ordinary test stops. The Arkansas Contractors Licensing Board is about construction contracting over a dollar threshold they publish. Confirm the current trigger with ACLB before you bid install projects. Testing a device for a restaurant is not the same as taking a building.

How do I report tests to an Arkansas water system?

Use that system's form or portal. Ask before your first test. Some still want paper dropped at the window. Keep your copy with the gauge readings, serial number, address, and pass or fail. If you fail a device, tell the customer and the utility the way that utility requires.

Is backflow testing a good first-year business in Arkansas?

It can be a decent side book if you already plumb or you live near a city with a strict program. It is a thin standalone business if you have no customer list and you refuse to drive. Nobody publishes honest first year tester revenue for Arkansas. Price against local competitors, not national blogs.

What insurance should a new Arkansas tester carry?

Start with general liability in the amount the water system names. Ask them. Add hired auto if you use a personal vehicle. Look at errors and omissions once reports are a real part of your income. If you have employees, talk to the Arkansas Workers' Compensation Commission. I would not buy a huge bundle on week one.
