I have a spa that had the booster pump not work for awhile so it was running with the air blower and it worked well. I decided it was time to fix the booster pump so i ordered the motor for it. I put it all together and when i turned on the jets with booster pump and air blower on it seemed to stop blowing bubbles out and would not work together, overheating the air blower. Turn off the booster pump and works fine again as far as bubbles coming out. This is an in ground spa. Also before the initial failure of booster pump it was working fine with no problems. Any ideas?
