Why does a 10-minute test cost $150?

Pros typically charge $75 to $150 per hour, and a short visit still includes travel, setup, and reporting. Prices also vary by location, property type, and number of devices. Commercial properties and larger cities often cost more than a simple residential test.

What should I check before I pay?

Ask the pro for proof of a South Carolina state certification and proof of licence and insurance. Confirm the quote covers the test, the report, and any repairs or extra devices. Repairs and testing are at the property owner's expense under Mount Pleasant Waterworks policy.

How often does my device need testing?

Mount Pleasant Waterworks requires backflow assemblies to be tested annually by a certified tester. Higher-hazard properties may need testing more often. Plan for this recurring cost when budgeting.

Why does backflow testing matter here?

Charleston-area water systems serve a humid coastal region where pressure changes can let contaminated water enter the potable supply. Testing confirms the assembly is working. The test is specialized work, not general handyman work.

What to do next

Confirm the tester holds a current South Carolina backflow prevention tester certification, since certifications expire every 3 years.
Ask for a quote that itemizes the test, the report, and any repair parts before work begins.
Ask whether the quote includes the certification report submitted to the water utility.
