I'm redoing my in-ground pool of unknown age (at least 30 years). Part of the project will include adding a spa. It will be formed & plumbed from scratch. I want the spa to have the advanced jets like a stand alone spa, vice the common open throat discharge. I've been searching the net & making calls but have not been able to find anyone that has any experience with this concept. It didn't seem that advanced to me; buy jets from spa company, install pvc sized for jets purchased.

Is there more to it? Am I missing something? Are there options that will thread on to standard 1.5 inch female outputs?

Thanks for any input.
