Plumbing pressure relief
I'm running on internal water (not city water). I don't leave the water heater turned on all the time (too wasteful to do so) and when I turn it on it raises the pressure in the whole plumbing system ...

No need to drain the water heater.
1. Turn off the pump.
2. Run hot water until no more will run.
3. Connect to city water. The hose should not have any water in it --- only air.
4. With the pump still off run some HOT water until all the air is out of the hose and in the water heater.
5. Now you can refill your freshwater tank.
The air in the hose will enter the water heater and form the air pocket.
When I connect to city water, I ALWAYS run hot water first to get the air in the hose to enter the water heater.
