Default If regular water is bad for cooling system should I flush with garden hose?

Im flushing my coolant this weekend and have a few questions to clear up. I already bought the coolant, mopar MS-9769 coolant, and will make that a 50/50 mix with distilled water.

Basic steps:

1. drain radiator then tighten drain plug back up
2. take out thermostat and reinstall housing
3. take lower radiator hose and put into bucket
4. start car and turn on heat full blast
5. put garden hose in radiator and flush system till it comes out clear
6. Once clear shut down engine, install thermostat, tighten everything back up and fill w/ 50/50 mix
7. Start engine, keep heat on full blast and radiator cap off to bleed system and fill as needed.
8. Done

My concern is the garden hose. I was told not to use regular water in the cooling system, so shouldn't I avoid the garden hose?

My idea is to just buy a ton of distilled water and pour that in the radiator instead to flush it.

what are everyone's thoughts on this?
