Hello and thanks in advance for any help provided. I am building a spool as an owner/builder and had some questions regarding plumbing. I say spool but this is basically a large spa. It is approximately 17 feet by 10 feet and 3.5 feet deep (single depth). Excavation is complete and steel is going in on Saturday.
I am trying to decide on proper plumbing pipe size. I have 2 pumps, one VS Intelliflo, 1 3 HP Whisper flow. A 420 cartridge filter and a 400,000 BTU Master Temp heater and a Polaris air blower already bought and paid for sitting in my garage.
The perimeter of the spool is about 54 linear feet and trench from pad to pool is about 25 feet. I want to put about 10-12 jets in here, nothing fancy just good action. I'm assuming standard jets would require 15-20 gpm per jet. We are planning on the following:
Suction lines from skimmer and drains at 2.5"
Air line at 1.5"
Two return lines one for each pump handling 5-6 jets each will have 2.5" up to where the loop starts and scale down to 1.5" for all jet connections
Would this be ok, or does the pipe size need to be bigger? Also, planning on placing second pump after heater so hot water continuously goes through all jets when spa is running.
