Troubleshooting Common Issues during Gas Valve Replacement

While replacing a water heater gas valve can be a smooth process, unexpected issues may arise. Here are some common troubleshooting scenarios you may encounter during the replacement process:

Corroded Connections

Corroded connections can make it difficult to remove the old gas valve or install the new one. One way to deal with this is to use a wire brush or sandpaper to scrub away the corrosion.
