Why Are backflow tests required?
Every home with an irrigation system is required to have a backflow prevention assembly. You may also be required to have a backflow prevention assembly if you have a swimming pool. Many businesses are also required to have a backflow prevention assembly for various reasons.
Backflow prevention assemblies are designed to prevent waste water, chemicals, and other hazardous substances from being pulled into the public water system from your home or office.
Your water provider requires that all backflow prevention assemblies be tested every year to ensure they are working properly.
A Quick Lesson On Backflow Terminology
You’ll see a lot of online information talking about PVB, RP, DCVA, water purveyors, etc.
SCDES (formerly SCDHEC): South Carolina Department of Environmental Services is the agency that administers the state’s cross connection program and certifies backflow testers.
Water purveyor = your water provider. Some of the larger water providers in our service area include Charleston Water System, Berkeley Water, Dorchester Water, Goose Creek Water, and Summerville Water.
DCVA = Double Check Valve Assembly. Most water providers no longer allow these for irrigation use.
RP = Reduced Pressure Principal Backflow Preventer. Used for irrigation and high hazard commercial facilities.
PVB = Pressure Vacuum Breaker. Used mainly for irrigation systems. Many water providers, such as Charleston Water, no longer allow PVBs to be installed for irrigation systems.

Why Choose Swell Guy Plumbing For Your Annual Backflow Test?
SCDES Certified Backflow Testers & Fully Licensed Plumbers: Some testers will only tell you if your system passed or failed. Because we are SCDES certified backflow testers and fully licensed plumbers, we can handle repairs, or replace the entire unit to keep your water running safely.
We Clean and Retest Before Recommending Costly Repairs: If your initial test fails, we don’t just hand you a failing grade and an expensive bill. Debris and dirty internal components are the most common reasons for a failed test. We will attempt to clean the internals and immediately retest to save you money.
Fast, Reliable Submissions: Once your assembly passes, we handle the paperwork and submit the results to your water provider by the end of the week. If it truly needs a repair, we’ll provide an upfront, transparent estimate.
Lowcountry Born and Raised: We aren’t a massive corporate franchise based out of California. We are local, experienced, and lifelong Lowcountry residents. When you call, we answer. When you text, we reply.
Honest Value Over Cheap Shortcuts: We might not be the cheapest tester in town, but we don’t cut corners. We value your time, protect your clean water, and want to be your go-to choice for years to come.
Please note: Because outdoor testing is highly dependent on the elements, severe weather events like heavy rain or freezing temperatures can occasionally impact our testing schedule.

Frequently Asked Questions
Some common questions we get from customers.
No, you don’t need to be home for us to complete your backflow test! However, if your backflow assembly is located inside a fenced area, please ensure the gate is unlocked and any pets are safely kept indoors during our visit.
Nope! If your irrigation system is officially retired, you don’t need to keep the backflow assembly. Swell Guy Plumbing can cap your inlet and outlet pipes safely underground and remove the assembly.
This service typically runs between $250 and $350.
Just a quick heads-up: We’ll need your water provider account info before we start so we can verify the line is only used for irrigation. (We aren’t able to disconnect assemblies that double as pool fillers!) We’ll also send the information to your water provider so you stop receiving annual testing notices from them.
