[enujmarathon]

Help! I have a new 2022 Jayco jay flight 174bh , and is trying to sanitize fresh water tank before 1 st use. According to the Manual I need to run hot faucet first until I small chlorine after filling up the fresh tank with chlorine solution, but the hot faucet just doesn’t have water coming out, yes, I have water pump on and can hear the sound. Cold water seems to be running with water pump. I tried both shower and kitchen sink, just air popping out for a long time , I tried like 5minutes for each , shall I try longer ? I am a newbie and any help is appreciated!

It is in bypass mode , I know I won’t get hot water , I just expect cold water comes out from my fresh water tank due to bypass.
