Hello and thanks for providing the forum. I've been doing some reading on my issue but hoping for some advice before I call the service guy.
We picked up a used 2008 Jacuzzi J-480 last January.
The J-480 has 2 pumps. Pump 2 controls the Jets for 2 seats, plus the water fall. The water fall can run all the time if wanted. Normally I leave it running on low as the system circulates. Right now the water fall is not coming on unless I turn on the pump. Currently if the jet is off, there is no flow to the waterfall. If the pump is turned on (only on/off not a off/low/high) the waterfall runs, but the seat jets to not. No jets and no bubbles. When I turn on the switch for that pump the water fall begins to flow and I can hear a humm, that humm lasts for several seconds then stops - it sounds like a switch. After a minute or so I can hear it activate again. This makes me think I am getting flow through the circulation side but not through the primary side (I hope that makes some sense. I do not think I have a air lock, but I haven't ruled that completely out either.
I have tried using my shop vac to clear the lines by blowing air through the diverter that would normally divert water between the two seats on that line. I have also done a drain and fill, the problem remained even after the fill. I have also tried using the hose to spray into several jets and I've used the ShopVac to blow into the waterfall diverter as well.
The problem remains though. I still have no water to the seats, though the waterfall works.
The other pump works just fine.
Any thoughts or advice? I am working slowly on removing the skirt, but because it's up to the deck that's a bit of a pain.
Thanks in advance.
Steve
