Jacuzzi JT365 Curc Pump goes again they say it gets clogged
Jacuzzi Jim:
After talking with Jason on the phone it really makes no sense as to whats going on, by what he describes to me there are chunks/psc of calcium that are clogging up the circ pump impeller. I think what might be happening is that calcium is breaking loose from the line and collecting in the circ pump impeller. I told him to drop his PH to as low as he can to maybe solve the problem and get rid of the build up. Whats strange is where the calcium originally is coming from to start with he doesn't use calcium increaser and is on city water.
Usually with calcium build up the walls/sides of the spa will be really rough to the touch "sand paper" like, he has none if this? Another thing is the line that runs from the filter to the circ pump is maybe 6 feet long, so the calcium has to be coming from that line. He is using bromine with the Jacuzzi inline bromine feeder that fits in the lid of the filter, possible chunks of bromine breaking loose and lodging in the pump is doubt full, it would have to get through the screen psc the filter screws into. I told him to switch to a chlorine system and see what happens, worse case Jason which I didn't mention is maybe the spa company can come out and replace the circ pump hose from the filter it wouldn't take much to do that.
Good luck with it Jason and feel free to call me anytime! Jim

Thanks for the insight JJ. That being said, the circ line is 3/4", I would suggest simply pulling the circ pump, using a plug stopper at both the suction screen in the filter bay, and the heater (3/4" vinyl short cut with plug), then inserting a 1/2" or 3/8" piece of vinyl tubing going to the suction screen and examine what comes out. I doubt you are going to find anything of significance, but it would tell the story of what is in that line.
Jacuzzi Jim:
Tell ya whats IDIOTIC? Its the spa company that's been repairing the tub, the dealer he bought from I guess went under and it's a Sundance dealer that's working on it. After the second pump replaced went bad a good tech should/would work the problem as to why, not just replace the pump and tell him his water is bad,specially after what they replaced it 4 or 5 times ::) Then tell him if another goes bad were not replacing it. ???
Alex. Ill take spa service 101 for 200!
Jason feel free to print this thread out and take it to the dealer!! ;D
Good idea Clover.

Yes I have to wonder...
So my shell is perfect...and my fliters are great! I know its doesnt sound right but they are.
I have now taken Jacuzzi Jim and believe you. I have dropped my PH and will wait a few days cycling through the pipes.
Hopefully that will liquify the calcium. I will then drain the tub and flip over to clorine instead of bromine and use qua finess.
