Fill and Vent Pipes

I just had a Roth 275 tank installed in my basement, the original copper pipes that ran through the siding were replaced by 2" steel through foundation

.

The pipes are horizontal, there is no pitch in either towards the tank. I'm aware of the reasoning behind having a pitch in both pipes: seeping through joints, the possibility of oil blowing out through vent after overfill, etc.

I've been told that having a pitch is not required, and that sometimes the run through the foundation prevents adding some pitch to the pipe.

Is this acceptable or do I need to insist that the installer return?

Please see the attached photo, thanks.

    I doubt you will have any issues. The installer looks to have done a nice job from what I can see.

    As far as the pitch issue goes, yes the pipes should be lower on the tank end. They look level.

    The only reason for pitch is so any oil leftover in the pipes will drain to the tank.

    As long as the pipes are not back pitched and are level you should be fine.

    Thanks Ed, I do believe that they did nice work and I couldn't imagine overfilling the tank to the point where oil got up into the horizontal part of the vent pipe, but I wanted to confirm with you experts.

    The vent pipe is ~6 feet long: would you have given that some support from the joist above or not necessary?

    Hopefully the fill is on the left. So its only about 2 ft horizontal.

    The only concern would be if the piping is below grade outside. If so I would've used galvanized over the black steel.

    Yes, the fill is just under 4' and the vent is 6', and both above grade.

    Have you put a level on them?

    Yes, I have a 2' level.

    That the pipes are horizontal as noted thanks.

    ARE THEY LEVEL OR PITCHED???

    In using my level to determine if the pipes were pitched towards the tank, I determined that they were not, so I wrote my original post. Naturally, I was referring to the horizontal sections as opposed to the vertical, so I assumed that it was clear what I meant by 'horizontal'. I guess I should have written either 'level' or 'perfectly horizontal' to make it clear, but others seem to have understood what I meant.

    I don't want to be a PITA (but I will if I need to be), it looks like they'd have to chip out whatever they patched with and then shorten the vertical, adjusting the 'swing' section accordingly.

    I posted in order to determine if it was something to be concerned with, it appears that it really shouldn't be.

    What is the desired degree of pitch, 1/4" per foot or similar? And should they have supported the longer pipe via the joist above?

    Edit: I took a closer look, both pipes are very slightly pitched towards the tank along the lines of 1/32" per foot.

    then it’s not an issue!

    It would appear that way, thanks.
