What should I do this week if I think I was overcharged last year?

Compare your old invoice to the per-device rate. A standard residential-style irrigation device is often priced around $40 each, while a DCVA or RPZ device is often around $65 each. Ask the new quote to list each device separately so the math is clear.

What should I check when hiring a backflow tester?

All backflow testing in South Carolina must be done by a state-certified backflow prevention tester. Ask the pro for proof of licence and insurance and confirm the tester certification is current. Certification is valid for 3 years and must be renewed.

Why do some quotes come in higher than others?

Prices vary by device type and access conditions. Some testers add charges for limited-access devices such as underground vaults. Ask whether a truck or service charge applies before you agree to the job.

How often do backflow devices need testing?

South Carolina requires annual testing of backflow prevention assemblies at least once every year. Charleston's wet climate, with about 45 to 58 inches of annual rain depending on the measurement source, makes timely annual testing important.

What to do next

Ask for a per-device quote listing each of the two devices and its type (standard, DCVA or RPZ).
Ask whether the quote includes the city submission fee and any truck or service charge.
Verify the tester's South Carolina backflow tester certification is current; certifications last 3 years.
Ask the pro about access for any underground or hard-to-reach valves before booking.

Quick answers

Is there a discount for testing multiple devices at once?

Volume discounts are not listed in our source facts, so confirm this in your quote. Ask the pro to price each device separately and to state any multi-device discount in writing.

Does the price include the city submission fee?

Our facts do not state whether a city submission fee is included in every quote. Ask the pro to itemize it so you can compare quotes fairly.

Are there extra charges for hard-to-access backflow valves?

Yes, limited-access devices such as underground vaults may cost extra. Ask for that charge to be listed in the quote before the work begins.

How does your pricing compare to other Charleston testers?

CHS Backflow is a free referral service, not the tester, so we do not set the price. Use the per-device ranges here and the state certification list to compare quotes from independent pros.
