Default New pressure relief valve stays open

Hi,

Just replaced my electric hot water system. I installed a new pressure relief valve. When I opened the mains and filled the system, it continues to run out past the valve. Any reason it would stay open? I have not connected power yet.

Thanks

What is the water pressure?
It is a pressure activated valve so you have to now what that is.
2nd What is the valve rated for. there is a tag on it that list it's rating.
maybe you have the wrong type of valve or the valve is defective

Thanks.
The valve came with the system.
It is rated at 1000kPa.
I really didn't think the head pressure here was that high, but I'll look into it. Thanks again.

could be defective. did you open it to bleed out the air? Don't do that.
Replace it

GUILTY, GUILTY. and GUILTY
Had a RayPac boiler that unless you popped the T&P after you had the building water shut off, it got air locked. This particular boiler had the flow switch bypassed. I know, don't say it, Not a safe thing to do. A professional boiler contractor maintains this one. Any who, when you try to heat a tube with little water in it, it is sounds like world war III just erupted.
When the T&P dribbles a little to long I just smack the stem on it.
They finally replaced the whole boiler about a year ago.
