First time posting. Can't figure this out. All the stuff I've been reading says to use pressure rated pvc. Pressure rated fittings will read NSF-PW on the piece. The 3" to 1.5" reducer I have and all I've seen online are not rated for pressure. I'm trying to make this

It seems all the pictures I've seen are using the standard pvc fitting from lowes/hd. Any help would be appreciated.

Ok...I've googled and checked the supplier links on the previous link. I cannot find a pressure rated 3 x 1.25 bell reducer. I thought McMaster would have had it for sure.

No. I was going to head back to Lowe's and check the ratings on those. I also thought of switching from 3" to multiple 2"
