I'm getting ready to replace an old check valve and 3-way Jandy with new ones, and since most of the pipes in the system are fixed to other parts/lines, at some point, I'm only going to be able to coat the pipe with primer/glue and push together without with any twisting to ensure good coverage. Is that just how it goes sometimes?
Lastly, any great ideas on how to plumb this?

Lastly, any great ideas on how to plumb this?
- I have a new Jandy flapper check valve for spa spillover, so I want to keep it horizontal (yellow star on purple line below)
- My existing 3-way can't be re-used due to prior attempts at reaming/re-gluing
- The polaris line will be connected to standard return, with a few less fittings.
- I will use my reaming tool to re-glue the top of the 3-way valve to the existing 2" elbow, so basically everything under the green line will be new.
