    IGP Spa jet venturi adjustment.

    Hi, all.

    Quick question. I have a IGP with a spa attached. I have five jets. Four of the five produce a venturi effect, but the one by the step does not when the blower is off. Is there any way to adjust this so it also has a venturi effect? I have tried adjusting the jet tube (screwing in and out various amounts), with no success on this particular jet.

    And ideas?

    If you have a blower on the air pipe and it is not running, it isn't a surprise that one of the jets isn't working. They really aren't designed to do that. The blower restricts air flow unless it is on so if you want to try the jets without the blower, remove the blower from the air pipe.

    Even then, it isn't guaranteed to work unless the spa was designed to work without a blower and many PBs don't know how to do this.

    Interesting.....I will try that this weekend. If it works, I'm sure I can create a cap with some holes it. Thanks for the suggestion!
