I just moved into a new place, and I've got an older gas hot water heater that I believe is an A.O. Power House Power Shot. There's a sticker on it from 2003, but I couldn't find a serial number or any installation date. So, I'm a bit concerned about whether the heater has ever been bled before. I want to keep it working as long as possible without racking up big expenses just yet. I've read mixed opinions online about whether bleeding the tank is a safe move for an old unit. Some say it could actually harm the heater by disturbing built-up sediment, while others have had no issues. Is it alright to drain it now to clean it out, or should I just wait until I'm ready to replace it?

Draining might not directly harm the tank, but it could cause leaks at the drain valve afterwards if it’s old. Make sure to check the sacrificial anode and pressure relief valve while you’re at it if you do decide to drain it, though. Just be cautious with such an old model!
As someone who's had their water heater for 26 years, I wouldn't touch that thing unless it's acting up. Draining could simply invite issues if it hasn’t been done before, especially if you don’t have the history on that heater. Better to leave it be if it’s still functioning well.
Appreciate your take! That’s what I'm leaning towards based on what I’ve read.
I wouldn’t recommend draining a worn-out heater. If it's working fine now, that could change if you disturb any built-up stuff inside. It's always a risk when dealing with older units. Just make sure to budget for a new one in the future!
Honestly, I wouldn't worry too much about flushing that old heater. Once they age, it's often more trouble than it's worth. I’ve seen tanks last over 20 years without ever being drained. Just continue to enjoy your hot water for now and save up for a replacement when the time comes, instead of risking potential headaches from draining it now.
Thanks for reassuring me! That totally makes sense. I guess keeping it running smoothly is the priority until I decide to replace it.
Thanks for the tips! I'll definitely keep those valves in mind if I ever go through with it.
