One thing that has come to mind on this subject: My J480 had 2 filters, a large one that I think fed the main pumps, and a slightly smaller one that I think fed the circ pump. Together their combined surface area would be fairly big. The Maax and Sundance spas didn't have quite the same total...

Hi, I've posted a number of threads which have separate issues being discussed. But something keeps merging them into the same thread, defeating the whole point of having separate threads in different forum areas. Asking about insulation is different to asking about jet pressure, which is...

Hi, We're looking at new hot tubs, and I've had a wet test of a Maax and a Sundance tub, but for some reason, in my mind they don't seem to have as much pressure coming out of the jets as our old Jacuzzi J480. Does the J480 have unique high pressure jets, or is my memory playing tricks on me...

Hi, I have a '07 Jacuzzi J480, and want to locate the subwoofer speaker unit. Does anyone know where it would be? I don't see it anywhere inside the motor compartment. Thanks - D

Hi, Does anyone know where the forum member Chem Geek is? He gave me some excellent advice several years ago when I was overhauling my hot tub. I don't see him here at the moment. Thanks - D

We've been looking at new hot tubs, and both the Bullfrog and Maax dealers say their tubs are at the top of the list of most efficient hot tubs. Bullfrog say the list on the Californian Energy Commission website, the Maax guy says it's on the Californian Energy Group website. We've searched...

Hi, We're looking at new hot tubs, and want some clarification on a few points: The Maax Spa dealer has combined UV / Ozonator units on his tubs. He says the UV acts not on the water but on the Ozone, turning it into a much more powerful sanitiser. Because of this, you hardly need any...

Hi TFPers, My '07 Jacuzzi J480 has started to leak. I suspect it's from a jet, but can't see any visible signs anywhere to point me to the jet responsible. One of my main pumps has a leak, prominent when it's running (sprays water off the driveshaft like a tap just slightly open), maybe that's...

Hi MDRagger88, It was from learned suggestions from here that I now operate at TA 40. It was said that, if using Borates at c. 40 - 50 ppm and CYN Stabiliser at c.30 - 40 ppm, the chemicals would be stable at TA 40, so that's what I've done for the past 7 years. I forget why TA 40 is good. I...

Hi TFP, Long time no post. Anyway, I've just upgraded my Controlomatic ChlorMaker to a Controlomatic SmartSpa, as my electrodes had failed after 6 1/2 years (a record apparently!). On the top of the control box, it states: Stabiliser: 0 Alongside recommended chlorine levels / pH / etc. Now...

I've checked from the phase and anti phase power feeds in reference to earth on both the circ pump and heater. I get no reading atall = no connection I have various multimeters. My main meters are currently: Precision Gold meter Sinometer M-830B

The underside of the circ pump.

Here's a photo of my circ pump. Note the white encrustation around the impeller housing to motor area.
