Hello everyone, I have a question and I hope I will get some help. I have a used PDC SPA hot tub , I have got from a family member. it is working fine and it is old with pneumatic push button control. it has two jets the filtration pump which runs continuously all the time is a full size jet pump similar to the second one. the other jet pump run either manually through the push button or through the timer. most probably I will upgrade the control system. here is the question Can I replace the full size jet pump that runs all the time with a tiny small pump that has no noise and save energy like the ones at the new SPA models? or the size of the pipes and the mechanical configuration will not work and must be a full size jet pump like the current one. Thank you appreciate your help and support.
