Water OK for 2 min Radiator test?

Hello. My replaced radiator in my 1990 sprung a leak which i hope i have amended w/ the help of the local radiator shop.

Anyway, i was wondering if i could test my leak repairs with normal water instead of antifreeze. I dont have a suitable container for catching leaked antifreeze and i cant afford to replenish my supply after every leak repair....soo...would normal tap water work to run in my radiator for like 2 minutes, or would it be a bad idea? Distilled water, if anything, or tap water OK?

I'm going to assume this is a dumb idea but i'd figure i'd ask anyhow...

Water is fine to run in the springtime. Just dont leave it in too log because it will rust your cooling system

would normal tap water work to run in my radiator for like 2 minutes

I skipped the water test and just went with antifreeze.... i figured that if it was going to leak id see it fairly soon since the leak was at the bottom of the radiator
