Recently, my water heater started leaking from the top edges. I can see rust lined up all along the outer rim on the top, and water is very slowly trickling out. I've made an appointment with a local water heater company to come repair it, but it will be three days before they can come. So now, I'm trying to shut down the water heater safely.
Since it's an electric heater, I've turned off the electricity on the breaker panel, and I've shut off the cold water valve on the top of the heater. I heard that I also need to drain the heater through the outlet near the bottom of the heater.
1. Is draining the heater through the bottom outlet necessary?
2. If I do drain the heater via the bottom outlet, will the water be scalding hot?
3. Why can't I drain the heater via my bathroom faucet? Will turning on the hot water in the bathroom cause any issues (besides not getting hot water of course)?
