Worst relief valve I've seen

couldn’t open if it had to

If it did release or open… where or what is it connected to?

Why is the discharge pipe going up?

Looks like it could open at any minute, tap it with you hammer:mrgreen::shock::stuck_out_tongue:

It is on the hot water tank, and it is going up because the handyman plumber did not know what they were doing…

I wonder if that is galvanic corrosion, probably, nothin’ dumba than a plumba!
