I have a 6x6 square spa with four jets connected via 2" PVC to intelliflow VS pump which is used used for both pool/spa. The venturi jets are connected to a 2" air pipe which extends approx 15' from my spa. Spa is located approximately 50' from pool equipment pad and is connected via 2” piping.
I noticed my existing venturi tee nozzles are 1/4" and assume I should I should swap these out with 1/2" or 7/16" venture nozzles to get better performance? Should I also change the return size on each jet? Return jet openings are 1.5” (rings w/o eyeball)?
If it matters venture tee nozzles are recessed approximately 10” behind the return jet opening.
Thanks in advance for recommendations.
