I just did a water heater flush at my rental house today, and had the tenant open the hot water at the sink.
but the wh was still draining really slowly, until I opened the tp valve, and the water finally started gushing out.
I kept the tp valve open for 30 minutes while i was flushing and draining.
any harm in doing it like this every year?
I don't know why there was still a vacuum even with the sink faucet turned on.
the wh is on a platform and the drain valve is about waist height.
