    What is my spa doing?

    Hi all! I'm new here. We just finished our new inground pool. It is about 35 ft x 24 ft. We have all pentair equipment. We just started heating our spa and it seems that when the heater is on sometimes the water coming through is very finely aerated. Anyone have any idea what could be causing this. It only happens when the heat is on to the spa and not to the pool. The spa heats very quickly. Here's a pic and I also have a video of it. The pool is a salt pool. The jets were not on at this time. Any info would be appreciated. Thanks!

    How long has your pool been plastered? I have read where most PB say to wait 30 days before using the heater. I am not sure why...........that might be a good search question.

    What did your PB say?

    We did wait the 30 days. It was plastered about 45 days ago. We didn't use heat or salt until the correct time.

    That is good news. Does it do it the whole time the heater is on or just at start up or for a minute or two?

    Looks like a suction side leak in the spa to me. Air is probably getting into the lines before they enter the pump. Try checking the unions and valves in the suction side of the spa leading up to the pool pump.

    1. Does your filter also get a air in it when this is happening? If you open the valve at the top of the filter is it air then water or just water that comes out?

    2. Can you run only the spa without the heater on and if so is the result the same?

    When I run just the spa I don't believe this happens... But I will go check. I will run the heater and check everything. I hope it is not a leak underground. Ugh! That would be a mess!

    I'll check the filter valve too.

    Of course right now it isn't doing it. Weird. It did it two nights in a row. I can't think of what is different.

    It got scared because it KNEW you had asked TFP! LOL

    My guess is there was some air pockets or such in the lines that just needed a few on/offs to work through.

    Well I'll try it again tonight perhaps and report back again. Seems like it was too much air for the fix to be so simple. But fingers crossed!
