Make sure that you open the pressure relief valve on the water heater so it can fill with water after the replacement.

Glad you got it working!
No need to open T&P Relief Valve when refilling.
Turn on water supply and then open nearest faucet hotside.
This will allow cold water to flow into WH Tank, displace the air in system AND establish the 'air pocket' at top of tank,
Air pocket helps control pressure increases when heating water as it will SWELL when heated so w/o air pocket pressure can increase and cause the T&P Relief Valve to 'weep'
Opening T&P can cause air pocket to be expelled vs being established
