Help with Connecting Primer

[Jeff8242]

I need some help understanding how to connect the primer lines that were installed during my plumbing rough-in. The white pex is the supply line and the two black pipes are the primer lines.

Please see the attached photo. Any information would be appreciated.

I assume from your question you intend on hooking up your trap primer to the water line.
if that is a lav sink rough in, I would hook it up to the drain, it would be a whole lot cheaper
but the choice is yours
here is how to hook up to both

Thank you very much for the information. In the blue drawing, what is the part used for #2 - trap primer?

Primer for what

For the basement floor drains.

the trap primer, lets a little water leak into the trap every time the water at the fixture is used

That would be the Trap Primer Valve. Where are those 2 primer lines coming from?
Oops too late.

The 2 primer lines go to the 2 basement floor drains.

Is there anything special happening in the distribution splitter after the trap primer or could I just split it using various threaded and pex fittings?

1/2" threaded brass to 1/2" pex, pex to 1/2" splitter to my two pex primer lines.

 

[frodo]

yes, it has a cone shaped thingy inside the splitter
that separates the water evenly,
you could do it if the tee was dead ass level

I get it now. It ensures equal distribution, which is critical. Thank you.

When I went to buy the parts for option 2, primer tailpiece, the salesman said I should be concerned about grey water sitting in my floor drains. I am not sure if it is a real concern but decided to go with option 1, just in case.

Thank you for the help.
