I have an inground, gunite spa that spills into my pool. It has a 2 hp spa pump, 1 hp blower, and eight (8) spa return jets as follows: six located approximately 7" above seat level and 2 located approximately 6" above floor in seat wall. The attached picture from during the spa construction shows the jet locations.
My problem is that the flow from the jets is uneven. The highest jets have more flow than lower jets, resulting in the foot area jets having very little flow. Is this to be expected? Can it be corrected, perhaps with different size jet inserts?
Thanks for any advice!
