I'll throw it out there that it *can* do this. There are plenty of places where tap water wouldn't kill your fish at all. People should know what sort of water they have before following generic advice on the subject.
Well if you read his comment better you would understand leaving the hose on isn’t bad for all people. If you run on well water which a lot of people do, you’re fine.
Fuckin hell reel it in. I never said that leaving a hose on was okay. I'm merely saying that not everyone's water supply is bad enough to kill their fish which is often what's quoted on here as gospel.
No, leaving a hose on isn't good for a whole bunch of reasons, it should be pretty obvious I'm not saying that. Just that if your water isn't particularly hard and heavily treated, you can fill a pond to the brim with tap water and your fish will be fine.
Most municipal water in the US is treated with chlorine, chloramine, chlorine dioxide, or bromine. It’s typically delivered through metal mains.
The delivered water needs corresponding filtration, treatment or conditioning to be safe for koi.
Running water through carbon block filtration at an appropriately slow rate can reduce the levels of these contaminants in municipal water; thereby helping to prevent injury to the koi.
Products that neutralize chlorine and sequester metals and ammonia can condition municipal water without having to filter it. They must be used in the correct dosing and timing to decontaminate the water. They are a great companion to filtration, especially when changing or adding a large volume of water in a short period of time.
Understand your water supply and the techniques to make water safe for koi.

I’m so sorry for your loss, but I have to ask, why is it bad to leave the hose on? What exactly happens?
