Hi, having a little problem, someone might be able to help figure out. I am not getting enough flow pressure to make the (4) jets roto, or even feel any pressure.
Have a Hayward Tristar 3200 2 H.P. 2 Spd Series Full Rated SP32202EE - rate at 80 gpm for 2" pipe
max horse power is at 2.7
I was told that the loss is 5.8 lbs per gallon? ( when the pump is lower than the spa)
the spa is a 350 gal unit
This pump unit is sitting approximately 6 ft below the water line, jets are about 20" below the water.
the pump is 60 ft away from the spa.
I run the pump on High speed.
using 2" line from the pump to the spa
then the looped lines connecting each spa jet body - Watwerway (210-5860) is 1- 1/2" all 4 are connected together on to the one 2" line.
the spa jets being used are: Waterway 210-6120 Poly Jet Internal Roto Smooth Face rated at 10 - 12 gpm at 15 psi.
It is a pool spa unit - so the same pump being used for filtration is being used for the spa jets, (set up on valves to divert water from one to the other.
I have great water flow to the return lines for the filtration, but once it goes to the jets, the 4 of them, it does not have pressure.
I plugged 3 of the jet lines at the spa, and have pressure, as I remove them one by one, the pressure disappears to a slow flow.?
Not sure which way to go? Is my pump large enough? its not a large body of water. ? a little lost.

Re: low water pressure output at spa jets
Some simplified will be of help.
What is the maximal pump pressure at zero flow? (or at some flow rate) - in psi
You need to have 15 psi for your jets - if I understand you correctly - in order to have 10-12 gpm.
I do not understand you words:
I was told that the loss is 5.8 lbs per gallon? ( when the pump is lower than the spa)
which loss did they mean, and loss should be declared in psi?
