A dielectric union stops corrosion where two different metals meet. Here is the Myrtle Beach guide.
The problem
Connecting copper to galvanized steel directly causes galvanic corrosion over time.
The union
A dielectric union separates the two metals with an insulating washer.
The spot
It is most common at the water heater where copper meets the tank's steel nipples.

Before you start
For Myrtle Beach homeowners, first identify whether the symptom is isolated to one fixture or appears across the home. Note when it happens, what fixtures were running, and whether the main shutoff is accessible. Photos and model numbers help a professional make a faster, more accurate recommendation.
A simple decision checklist
Before approving work in Horry County, ask what caused the problem, which repair options were considered, what access or permit work is included, and how the finished work will be tested. Confirm the scope, materials, cleanup, warranty, and price in writing.
When to stop DIY work
Stop troubleshooting if water is near electricity, sewage is entering the home, a gas appliance is involved, a pipe may be frozen inside a wall, or the repair requires opening a structural surface. Shut off water when safe and call a qualified professional.
