I just replaced my water heater with the same 11 gallon heater I had before. The old one was working but was 6 years old so I thought I’d be proactive. I made the same connections but water only flows out of the cold faucet. The hot side just spits or doesn’t flow at all. Any ideas? Perhaps air in the line or the hot water tank didn’t fill all the way when the new system was turned on? I’m at a loss so any insight would be appreciated. Thanks!
