can anyone help, i have a in ground pool with spa that spill over. It has venturi jets but there is not enough pressure coming out ( not enough air mix). the pressure gauge say 19 psi when the spa is on. We have tried covering one of the jets to make the other jets work harder but water starts coming out the vent that's on the outside of the spa. ( think this is suppose to suck in the air to mix with the water to make pressure) We have taken out the venturi jets and run the spa and no debits come out so i don't think its blocked . Another factor could be that someone put in a 1 1/4 hp pump and motor. would just like some advise before we change it to a 2hp motor and pump.
