We had Navien tankless water heater installed about a week ago. The pressure relief valve was installed away from the drain opening in the floor and the installed told us that it was ok beacuse there wouldn't be any water leaking from it anyway.
Well, there has been quite a bit of water coming from the pressure relief pipe, flooding the floor in that area.
My question is: Should the pressure relief valve leaking this often or was the pipe installed incorrectly away from the drain?
Thanks for your help!
