We have 2 of these in our 19-year-old Sonoma (by Jet-ster) excercise spa, and I'd like to remove it. The jet opening is about 1-1/4" and two of these are on a 2HP pump by themselves.
The other 7 main jets are American Products, pumps and filter were Hayward.
Should they screw out?

Thanks for you advice to others that helped get the A.P. jets out.
