Trap seal primer set-up

[Jeff8242]

I am having trouble getting a plumber to install a trap seal primer, so I will try it myself.

I have a pex supply line (white). I have 2 pex drain lines (black) that run to the traps in the basement floor.

I will use the PPP P1-500 (primer value) and PPP DU-4 (distribution unit) and various

Please see my diagram below.

I must pass an inspection on this.

Thank you.

What we do:
Start with lever handle ball valve, 1/2” brass nipple, the a 1/2” x 1/2” no burst to the PPP device.
Without a lot of pressure differential (like toilet flush) those PPP don’t drip much.
The no-burst flex line allows for easy servicing.
