North Charleston, SC: what's different here
North Charleston sits in Charleston County, about 6 miles and roughly 10 minutes by car from Charleston via the main highway. The climate is humid subtropical, with hot, humid summers and mild winters. Those conditions can support seasonal irrigation use and year-round plumbing exposure, which matters for irrigation backflow assemblies at the water meter.
How much does a water meter backflow test cost in North Charleston?
Published Charleston-area prices start at $40 per residential irrigation device, with $65 for DCVA and RPZ devices. Another provider lists $55 residential and $80 commercial subscriptions, plus a $25 dig fee if excavation is needed. Limited-access devices may cost more.
How often does North Charleston require a water meter backflow test?
South Carolina requires each approved backflow assembly to be tested at least once annually by a certified tester, unless a specific exception applies. Assemblies must also be tested after installation and before use by the customer. Ask the pro which schedule applies to your device.
Who can perform a backflow test in North Charleston, SC?
South Carolina requires all backflow testing to be done by a state certified backflow prevention tester holding an up-to-date certification card. Certification expires every 3 years, and recertification requires a written exam plus hands-on testing of a double check valve assembly, pressure vacuum breaker, and reduced pressure principle assembly.
What equipment does the tester use on my water meter backflow test?
The tester's differential pressure gauge must be accurate within 2% of full scale or +/-0.3 psi differential. Certified testers fall into four state categories: General Tester, Limited Tester, Inspector Tester, and Manufacturer's Agent.
