Just had my pool and spa resurfaced and tiled. They removed the special spa jets during the process and now I have noticed a few issues which I have never had in the last 16 years.
1. Water backed out the blowe tub so hard it blew the blower off the pipe. This has happened about 3 times in the last month. I have never seen water even come out the pipe before. This has not happened anymore today with my testing after I noticed two of the spa jets were not screwed in all the way.
2. Before the spa had air mixed with water without the blower on and now it is only water.
3. When the blower is on only 2 of the 5 jets get bubbles.
4. If I remove the jets from the spa then more get bubbles with the blower on. When you removed a jet then it would immediately start getting bubbles.
All equipment has has been cleaned and there appeared to be no blockages. I am wondering if it is the air/water mix settings on these 4 jets. There is one jet which is a different style that I cannot figure out how to remove but it does not appear to have a setting to adjust the air mix but has always gotten more air then the other jets. Currently with all jets screwed in the different jet and one other get all the bubbles.
