Question regarding plumbing for next year.
Equipment is only a few feet from pool and current setup has flex hose connecting skimmer to pump to filter to return.
I’d like to introduce shutoffs and possibly unions as these components seem to have value for experienced pool owners.
With that said, what would be a recommended order of installation?
Skimmer to union to shutoff valve to pump to etc… Should I replace the flex with PVC (if so, why?)
Any other suggestions and links to visual aids would be appreciated, as well as existing TFP threads on this matter.
