Where the alert applies
The alert covers Summerville, Goose Creek, and Charleston. Sub-freezing temperatures can crack backflow preventer bodies and test cocks. Drain or insulate these assemblies to prevent damage.
5 things to check right now
- Insulate exposed assemblies. Wrap backflow preventers with foam covers before temperatures drop below freezing. This helps prevent cracked bodies and test cocks.
- Drain irrigation lines. Allow water to drip slowly or drain lines if possible. Standing water in pipes can freeze and cause bursts.
- Check for leaks. Inspect the assembly for visible cracks or dripping water after the thaw. Do not touch frozen components directly.
- Schedule a retest. If repairs are made, the device must be retested by a certified pro. Ask the pro for proof of licence and insurance.
- Call for referral. Contact CHS Backflow at (843) 286-4721 to connect with a local tester. We do not perform the work ourselves.
Testing Costs and Fees
Typical backflow tests cost between $75 and $175 per device. Some residential tests are advertised at $85 for standard sizes. Commercial tests may run $125 for larger devices. Emergency same-day tests can cost $225.
Signs of Freeze Damage
Look for cracked bodies or broken test cocks on the assembly. Water pooling around the device indicates a potential breach. Do not attempt to repair cracked brass or plastic parts yourself. A local pro must handle replacements and recertification.
Hiring a Local Pro
We provide free referrals to state-certified testers in your area. Always ask the pro for proof of licence and insurance. Scheduled tests often avoid dispatch fees found in emergency calls. Verify certification status through the state program list.
