New pool build -- pipes and pump sizes

[eljefe281]

I've read about your pool build eljefe, your pool looks great. So can a 1 HP pump drive 8 spa jets? They wouldn't allow me more than 6 even with the 2.5.

Thanks for the answers.

Thanks for the kind words.

I have a 1 HP pump feeding 8 spa jets and they are plenty strong for my taste. I also have a blower to juice them up when I want more action.

Each of my jets is designed for 13 gpm, so eight of them would require 104 gpm. Remember, if you have a separate jet pump, you won't have the pressure drop of the filter, SWCG, heater, and three-way valves in that circuit, so a given sized pump will deliver more flow.

I looked up the outlet pressure that the jets are designed to operate at, added some pressure drop for the piping and the jets themselves, converted the result to feet of head, and selected a pump by reviewing the pump curves.

In any event, I can't imagine needing more than 1.5 HP for a spa jet pump service (separate from the main circ pump).
