Is it OK to drain hot water tank?

Why does my hot water heater not drain?

Easy enough, right? If you’re not so fortunate, and are experiencing issues where the tank won’t drain there’s a good chance the drain valve is clogged or blocked.

Why is there air coming out of my hot water tank?

As you open the drain tap, cold water will continue to enter the tank — remember, the feed is still open.

If you do want to check your tank for sediment, place the hose into a bucket (outside) and fill it halfway.
