J 465 has a primary filter and a secondary filter. Here is what I discovered;
The water ONLY flows across the secondary filter when one the blower motors or motors are running. When the Hot Tub is just recirculating in Primary mode, No water flows across the Secondary filter.
If you set up the timers for primary and secondary filter, you will see that the secondary filter timer actually runs a blower motor and the recirculation pump. It is near to impossible to take off the secondary filter cap when in this mode.
When the Primary filter is running, Water only flows across the primary filter; The cap is easily removed without resistance on the secondary filter.
Can someone explain what is going on in the underneath plumbing to make this happen?
Thanks for the help.

Your circ pump draws through the floating wier side of the filtration, pump 1 draws through the closed system. Pump 2 draws from two of the suctions in the btm of the spa. Pump 2 use to draw from the closed system but they changed it.
As far as plumbing goes pump 1 is tied into the fitration (closed system) then it also probably draws from one of the suctions as well. There should be a check valve built in between the filtration part and the suction part then tee's to the pump. This is so if the filter becomes so clogged up, the check valve will open and alow water to come from someplace else other than the closed system.
Most spas today "except" the upper end H,Spring and all the Cal-Spa's will always have multiple suctions to draw from so you don't have so much suction coming from one suction that a child or (adult for that matter) can be trapped by it.
VGB act I believe. Virginia Graham Baker act which you can look up if you wish, a very sad story that has changed safety standards in pools and spa's.

are some of the new Cal's setup differently? all the new models I've seen still have bypasses on the bottom of the spa, but then again they have dozens and dozens of models so admittedly I haven't seen them all of course. To my knowledge Hot Spring is the only tub still setup to filter 100% of the water while jets pumps are running

Cal has something called safety suction.. If the suction becomes blocked it alows air to be sucked in from somewhere to break the seal? Something like that, has nothing really to do with filtration.
On a side note, why hasn't anybody else done the 100% no by-pass filtration? (maybe they have) You would think, if it's so great why don't more manufacturers do it?? I will admit it is a great selling tool just strange HS is the only.
Just curious..

Well, I know when both Jets/blower motors are running on my J 465, The circulation pump runs also. Actually anytime 1 or both of the jet pumps are running the circulation pump where the big filter is automatically come on.
I do not see how the primary filter could ever be bypassed but I could be wrong.
I run my circulation pump a max of 6 hours a day; As much water as this pump turns over, I feel it is more than enough.
Jacuzzi Jim:
Circ pump filtration is only dedicated to a filter, not many kids or stupid people are going to get sucked into or stuck the the filter system. I suppose if a really fat person sat their butt up there without the floating wier there, they would get one heck of a hickey. :o

Anyone that ignorant needs to buy a kiddy pool. 8) It would be VERY uncomfortable to even get ones booty to the opening on the weir; If one attempts this, make sure you sit and not the other way; That would "really suck" :D

Honestly don't know...cost of manufacturing comes to mind, but that would be a question for the sales reps from various companies that don't use it...One thing I have learned since we have spas with both styles of filtration (always at least 4 models filled in my showroom) is that you can never have enough circulation and filtration...it just makes for slightly less maintenance and chemicals in the end....I would never even contemplate buying a spa without 24hr cirulation
