My home hot water heater appears to be releaing water via the presure
release value. Its a Gas 40 gallon heater that is 3 years old. I keep the
water temp on the tank at its highest setting. Should flush the tank and
turn down the temp or do I have a much bigger problem.
Thanks in Advance.
The temperature and pressure relief (T&P) valve is your water heater's last ditch
defense against a dangerous event. The time is past for do-it-yourself repairs
once your T&P valve is opening. The huge catastrophic potential within a 40 gal
water heater is not something to mess around with. Call a plumber and be safe.

It might be as simple as the expansion tank being waterlogged, or maybe
the relief valve itself is defective. The dangerous possibility is that the
gas valve isn't shutting off properly, causing the water to heat way past
its norm. Does the water seem super-super hot (like scalding)?
If the water seems normal in its heat, then have someone check the
expansion tank and change the relief valve. Remember, if the tank itself
isn't leaking, then there's no need to change the whole water heater (unless
it's cheaper than messing with the gas controls.
