woke up and water heater noise and water discharging outside
I just woke up, went to the restroom i kept hearing a noise, i assumed someone was washing clothes. As I went to the kitchen the noise was louder and i checked the laundry room. I'm not familiar with terms so excuse my description but the noise was continuous and sounded like air blowing inside the electric tank. I turned off the breaker, looked outside and water was pouring on the ground and with the breaker off the air sound from the tank continued and water kept flowing outside. I just released relief valve a month or so ago so i didn't think that would be a problem. But, i went ahead and released it, the loud air blowing sound stopped as well as the water outside.
Any thoughts on what may have caused the issue. I must admit, its pretty startling to wake up to something like that and a little panic because at first you wonder if this tank is going to burst while i'm releasing the valve burning me.
Currently hot and cold are working normal and the i don't hear any noise coming from electric hot water heater. The temperature the past 2 nights have been 24 and 27 Fahrenheit. The coldest nights of the year here so far. I don't know if that effects water heater.
The relief valve is probably a little over a year old, that a plumber installed.
A couple of quick questions the relief valve dial is currently at 6 o'clock. I left it a month or so ago at 12 o'clock. When you release does it matter? also when you release or have a bunch of water released outside like this morning are you supposed to run the water or anything before starting back up? Thanks
