I have a problem with my spa jets - and am doing everything I can to try and research the problem before posting a generic 'help' request. I am sure my problem is already answered in one of the threads here, I just need to piece together a few more details.
These are the two threads I have been focusing on
The background - I have an in-ground pool with a spa that overflows into it. (It was built in 2000, and we bought the house in 2010). Since we have been here we have always had to run the air blower for a few minutes when switching to spa mode to encourage the jets to start acting like a spa (the venturi effect?). We could then turn off the blower and the jets would work ok - although certainly some seemed to be at a lower pressure than others. I never thought this was behaving correctly - but it got the job done.
In the past few weeks this process has stopped working - as soon as we turn the blower off the jets go back to just shooting water into the spa with no noticeable air in the stream (a few bubbles here and there). I have also noticed that one of the water returns into the pool itself has a few bubbles in it.
One of the main questions I have is that, given there is an air blower, should there also be a separate air vent for when the air blower is off? Or is the air pulled down the same tube that the blower is attached to? I can't find anything that looks like it it would otherwise be an air intake for the jets?
Appreciate any help in understanding how this is meant to work!
