Pardon my newb-ness, but I just bought a 2005 model year Master Spa Legend in really nice shape. Had it about a month now.
The pumps work great, some jets are so strong that they push you out of the seat!! I am very satisfied.
However, there are two seats in the tub, they are upright seats (not lounges) with 2 back jets. A bigger jet and a little one. The little jet on both puts out ample flow, but the big jet barely does anything. Adjusting the air, pumps, etc... doesnt change this.
Funny that its on BOTH of the seats. Every other jet works great. Ive tried turning the ring (they are ON), what do I do next?
